Safety Overview
Throughout this publication, safety warnings appear in procedures that can harm you if performed incorrectly. A warning symbol precedes each warning statement.
Supervisor Engine 6L-E
This section describes the Catalyst 4500 E-series Supervisor Engine 6L-E (WS-X45-SUP6L-E). See Figure 1. This supervisor engine provides IPv6 data path and data control for all Layer 2 network interfaces, and provides 10-Gigabit Ethernet interfaces for uplinks.
The Supervisor Engine 6L-E is supported in the Catalyst 4503, 4506, 4507R, 4503-E, 4506-E, and 4507R-E switches. On the Catalyst 4503, 4503-E, 4506, and 4506-E switches, you can install the Supervisor Engine 6L-E only in slot 1. On the Catalyst 4507R switch, you install the primary supervisor engine in slot 1, and you can install an optional redundant supervisor engine in slot 2. On the Catalyst 4507R-E switch, you install the primary supervisor engine in slot 3, and you can install an optional redundant supervisor engine in slot 4. The supervisor engines in a redundant system must be of the same type.
The supervisor engine is hot swappable, but packets are not forwarded when the last supervisor engine has been removed from the switch. When a supervisor engine is reinserted into the switch, the supervisor engine reboots.

10-Gigabit Ethernet Uplink Ports
The 10-Gigabit Ethernet uplink ports operate in full-duplex mode only. These ports use the hot-swappable X2 optical transceivers. The X2s have SC connectors to interface with multimode fiber (MMF) and single-mode fiber (SMF) cable. For further information on X2s, see the "X2 Installation" section.
When two Supervisor Engine 6L-Es are present in a Catalyst 4507R or Catalyst 4507R-E switch, one X2 uplink is active on both the primary (active) and secondary (standby) supervisor engines by default, or two uplinks will be active in a nonredundant configuration.
Gigabit Ethernet SFP Uplink Ports
If you want to use SFPs instead of X2s as your uplink transceivers, you can use the Cisco TwinGig converter modules already provided in the X2 slots. Installation documentation for Cisco TwinGig converter modules can be found at:
http://www.cisco.com/en/US/docs/switches/lan/catalyst3750e_3560e/hardware/install/notes/1757202.html
Note The 10-Gigabit Ethernet ports default to operating at 10-Gigabit, and will need to be configured in Software to use the Cisco TwinGig converter modules. For details on this configuration change, refer to the chapter on configuring interfaces in the configuration guide for your software release.
Ethernet Management Port
The Ethernet management port, also referred to as the Fa1 or fastethernet1 port, is a Layer 3 host port to which you can connect a PC. You can use the Ethernet management port instead of the switch console port for network management. When managing a switch, connect the PC to the Ethernet management port on a Catalyst 4500 series switch. (Figure 2).
Note When connecting a PC to the Ethernet management port, you must assign an IP address.
Figure 2 Connecting a Switch to a PC
By default, the Ethernet management port is enabled. The switch cannot route packets from the Ethernet management port to a network port, and from the network port to the Ethernet port. To obtain these, the Fa1 interface is automatically placed in a separate routing domain (or VRF domain), called mgmtVrf. (You observe the ip Vrf forwarding mgmtVrf line in the running configuration when you boot up.)
Even though the Ethernet management port does not support routing, you might need to enable routing protocols on the port. As illustrated in Figure 3, you must enable routing protocols on the Ethernet management port when the PC is multiple hops away from the switch and the packets must pass through multiple Layer 3 devices to reach the PC.
Figure 3 Network Example with Routing Protocols Enabled
The specific implementation of Ethernet management port depends on the redundancy model you are applying.
Console Port
The Catalyst 4500 E-series Supervisor Engine 6L-E console port has an EIA/TIA-232 RJ-45 connector. The console port allows you to perform the following functions:
•Configure the switch from the CLI
•Monitor network statistics and errors
•Configure SNMP agent parameters
Note EIA/TIA-232 was known as recommended standard RS-232 before its acceptance as a standard by the Electronic Industries Alliance (EIA) and Telecommunications Industry Association (TIA).
Reset Button
The Reset button is used to restart the switch.
Note Use a paper clip or other small, pointed object to press the Reset button.
Compact Flash Port
The Flash port accepts both 64 MB and 128 MB Type 1 CompactFlash cards. You can use it for file transfer tasks such as loading a new software image. The Flash card is optional and can be obtained from third-party suppliers.
For more information, refer to Using the Compact Flash on the Catalyst 4500 Series Supervisor Engines at the following URL:

Removing the Supervisor Engine
All Catalyst 4500 series switches support hot swapping, which lets you install, remove, replace, and rearrange supervisor engines and switching modules without powering the system off. When the system detects that a switching module has been installed or removed, it runs diagnostic and discovery routines automatically, acknowledges the presence or absence of the module, and resumes system operation with no operator intervention.
This section contains the following subsections:
•Installing the Supervisor Engine
•Removing the Supervisor Engine
Note When installing modules in a chassis with empty slots, populate the upper empty slots first and work down.
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040Required Tools
You will need these tools to install a supervisor engine in a Catalyst 4500 series switch:
•Number 1 and number 2 Phillips screwdrivers for the captive installation screws on most modules
•3/16-in. flat-blade screwdriver for the captive installation screws on other modules
•Antistatic mat or antistatic foam
•Wrist strap or other grounding device
Note Whenever you handle supervisor engines, use a wrist strap or other grounding device to prevent electrostatic discharge (ESD) damage.
Preventing Electrostatic Discharge Damage
ESD damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Port adapters and processor modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.
Following are guidelines for preventing ESD damage:
•Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
•Connect the equipment end of the strap to an unfinished chassis surface.
•When installing a component, use any available ejector levers or captive installation screws to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.
•When removing a component, use any available ejector levers or captive installation screws to release the bus connectors from the backplane or midplane.
•Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.
•Place a removed component board-side-up on an antistatic surface or in a static shielding container. If you plan to return the component to the factory, immediately place it in a static shielding container.
•Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components from ESD voltages on the body; ESD voltages on clothing can still cause damage.
•Never attempt to remove the printed circuit board from the metal carrier.
Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm (Mohm).
Installing the Supervisor Engine
Catalyst 4500 series and Catalyst 4500 E-series switches have horizontal chassis slots that are numbered from top to bottom. On the Catalyst 4503, 4503-E, Catalyst 4506, and 4506-E switches, you can install the supervisor engine only in slot 1. On the Catalyst 4507R switch, you install the primary supervisor engine in slot 1, and you can install an optional redundant supervisor engine in slot 2. On the Catalyst 4507R-E switch, you install the primary supervisor engine in slot 3, and you can install an optional redundant supervisor engine in slot 4. The supervisor engines in a redundant system must be of the same type.
Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034
Caution To prevent ESD damage, handle supervisor engines by the carrier edges only.
To install a supervisor engine in a Catalyst 4500 E-series switch, follow this procedure:
Step 1 Take the necessary precautions to prevent ESD damage as described in the installation guide for your switch.
Step 2 Ensure that you have enough clearance to accommodate any interface equipment that you will connect directly to the supervisor engine ports.
Step 3 Loosen the captive installation screws that secure the switching-module filler plate or the existing supervisor engine (whichever is present) and remove it.
Step 4 Remove the supervisor engine filler plate or the existing supervisor engine from slot 1. If a switching module filler plate was installed, save it for future use. If you are removing an existing supervisor engine, see the "Removing the Supervisor Engine" section.
Step 5 To install the new supervisor engine, grasp the switching module front panel with one hand and place your other hand under the carrier to support the supervisor engine, as shown in Figure 4. Do not touch the printed circuit boards or connector pins.
Step 6 Align the edges of the supervisor engine carrier with the slot guides on the sides of the switch chassis, as shown in Figure 4.
Figure 4 Installing the Supervisor Engine in the Chassis (Catalyst 4506-E Shown)
Step 7 Pivot the two module ejector levers out and away from the faceplate.
Step 8 Carefully slide the supervisor engine into the slot until the notches on both ejector levers engage the chassis sides.
Step 9 Using the thumb and forefinger of each hand, simultaneously pivot in both ejector levers to fully seat the supervisor engine in the backplane connector.
Caution Always use the ejector levers when installing or removing a supervisor engine. A supervisor engine that is partially seated in the backplane will not function correctly.
Step 10 Use a screwdriver to tighten the captive installation screws on each end of the supervisor engine faceplate.
To check the status of the module, follow these steps:
Step 1 Ensure that the LED labeled Status is green (module operational).
Step 2 When the switch is online, enter the show module command. Verify that the system acknowledges the new module and that the module's status is good.
Step 3 If the module is not operational, reseat it. If the module is still not operational, contact your customer service representative.
Removing the Supervisor Engine
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051
Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034
Caution To prevent ESD damage, handle supervisor engines by the carrier edges only.
To remove a supervisor engine from a Catalyst 4500 E-series switch, follow this procedure:
Step 1 Disconnect any network interface cables attached to the ports on the supervisor engine that you intend to remove.
Step 2 Loosen the captive installation screws (see Figure 5).
Figure 5 Captive Installation Screws and Ejector Levers
Step 3 Grasp the left and right ejector levers and simultaneously pivot the levers outward to release the supervisor engine from the backplane connector. Figure 5 shows a close-up of the right ejector lever.
Step 4 Grasp the front panel of the supervisor engine with one hand and place your other hand under the carrier to support and guide it out of the slot. Do not touch the printed circuit boards or connector pins.
Step 5 Carefully pull the supervisor engine straight out of the slot, keeping your other hand under the carrier to guide it.
Step 6 Place the supervisor engine on an antistatic mat or antistatic foam, or immediately install it in another slot.
Step 7 In chassis configured with redundant supervisor engines, if the chassis slot is to remain empty, you must install either a blank faceplate (C4K-SLOT-CVR) or a blank line card (C4K-SLOT-CVR-E). The following guidelines explain when to use a blank faceplate and when to use a blank line card.
•If you have either a Catalyst 4507R or a Catalyst 4510R switch chassis, you must install the blank line card (C4K-SLOT-CVR-E) rather than the blank faceplate to cover the empty chassis slot. A blank faceplate does not direct sufficient airflow to adequately cool the remaining Supervisor Engine 6L-E.
•If you have any other Catalyst 4500 series chassis, you can install the blank faceplate (C4K-SLOT-CVR) over the empty chassis slot. The airflow is sufficient to adequately cool the remaining Supervisor Engine 6L-E.
Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029
Memory Upgrade
This section describes how to perform a memory upgrade from a MEM-X45-512MB-LE (shipped with the supervisor engine) to a MEM-X45-1GB-LE. You might need to upgrade memory on the Supervisor Engine 6L-E for the following reasons:
•To upgrade to a new Cisco IOS feature set or release that requires additional memory. (Memory requirements for each feature set and release are available in the release notes for that release.)
•To use very memory-intensive features.
This document describes how to upgrade dynamic memory. The Supervisor Engine 6L-E ships with 512 MB and can be upgraded to 1 GB in the form of an SDRAM SODIMM.
Tools and Equipment Needed
You need the following tools and equipment to remove and install DIMMs in a Supervisor Engine 6L-E:
•ESD-preventive wrist strap
•Antistatic mat
Performing a Memory Upgrade
This procedure presumes you have already removed the supervisor engine from the switch, as described in the "Removing the Supervisor Engine" section.
To upgrade the memory, follow these steps:
Step 1 Attach an ESD-preventive wrist strap and ensure that it makes good contact with your skin. Connect the equipment end of the wrist strap to the metal back plate of the chassis, avoiding contact with the connectors.
Step 2 On the mainboard, locate the DIMM module slot. The Supervisor Engine 6L-E has one slot, which already has a MEM-X45-512MB-LE installed. (See callout 9 in Figure 6.)

Caution Handle the SODIMM by the edges only; do not touch the memory modules, pins, or traces (metal fingers along the connector edge). Handle carefully. DIMMs are ESD-sensitive components and can be damaged by mishandling.
Step 3 Release the plastic clips for the DIMM slot, and press down on them to unseat the 512 MB DIMM module. (See Figure 7.)
Figure 7 Removing DIMMs in the Supervisor Engine 6L-E
Caution Handle the DIMM by the edges only; do not touch the memory modules, pins, or traces (metal fingers along the connector edge). Handle carefully. DIMMs are ESD-sensitive components and can be damaged by mishandling.
Step 4 Hold the DIMM between your index fingers (See Figure 8). The DIMM is notched on the connection edge, and there is a corresponding key on the memory slot, make sure they are oriented to seat correctly.
Figure 8 Handling a DIMM
Step 5 Tilt the new 1 GB DIMM to the same angle as the socket, then insert the connector edge into the socket. Gently push into place until the plastic clips snap into place. (See Figure 9.)
Figure 9 Installing a DIMM
Caution It is normal to feel some resistance when installing a DIMM, but do not use excessive force and do not touch the surface components.
Step 6 Check the plastic clips for a secure and similar fit. If necessary, carefully remove and reseat the DIMM.
Step 7 Replace the supervisor engine in the switch as described in the "Installing the Supervisor Engine" section.
Step 8 To verify the upgrade was successful, look for the following output lines in the bootup output, or in the results of a show version console command:

Attaching Module Interface Cables
Figure 10 and Figure 11 show the connector types used to attach interface cables to the supervisor engine.
Figure 10 RJ-45 Connector
Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables. Statement 1021
Note Always keep caps and plugs on the fiber-optic connectors on the cable and the switch when they are not in use.
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051SC Connector
The SC connector, shown in Figure 11, is used to connect fiber-optic module ports or transceivers with the external SMF or MMF network.
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051
Note Make sure that the optical connectors are clean before making the connections. Contaminated connectors can damage the fiber and cause data errors.
Always insert the network connector completely into the socket. A secure connection is especially important when you are establishing a connection between a module and a long distance (1.24 miles) (2 km) network or a module and a suspected highly attenuated network. If the link LED does not light, try removing the network cable plug and reinserting it firmly into the module socket. It is possible that dirt or skin oils have accumulated on the plug faceplate (around the optical-fiber openings), generating significant attenuation and reducing the optical power levels below threshold levels so that a link cannot be made.
Caution Use extreme care when removing or installing connectors so that you do not damage the connector housing or scratch the end-face surface of the fiber. Always install protective covers on unused or disconnected components to prevent contamination. Always clean fiber connectors before installing them.
Figure 11 SC-Type Fiber-Optic Connector
LC Connector
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051The LC fiber-optic connector, shown in Figure 12, is a small form-factor fiber-optic connector that provides high-density fiber connectivity. The LC connector can be used with either MMF cable or SMF cable. The LC connector uses a latching clip mechanism that is similar to the one used on the RJ-45 copper connector.
Note Make sure that the optical connectors are clean before making the connections. Contaminated connectors can damage the fiber and cause data errors.

Configuring Your Supervisor Engine
For information and commands to configure your supervisor engine, refer to the software configuration guide for your switch. Configuration guides are located at:
X2 Installation
An X2 transceiver is a hot swappable input/output device that plugs into the 10-Gigabit Ethernet port of the supervisor engine and links the supervisor engine with a fiber-optic network. X2 transceivers are online swappable.
Full documentation of the X2 transceiver is in the 10-Gigabit Ethernet X2 Transceiver Installation Note.
You may also use Cisco TwinGig and Cisco OneX converter modules in these ports. Installation documentation for Cisco TwinGig converter modules can be found in the Installation Notes for the Cisco TwinGig Converter Module.
For supported X2 transceiver media types, refer to:
Tip For complete information on inspecting and cleaning fiber-optic connections, refer to the white-paper document at this URL:
http://www.cisco.com/en/US/tech/tk482/tk876/technologies_white_paper09186a0080254eba.shtml
Caution The 10-Gigabit Ethernet X2 transceiver is a static-sensitive device. Always use an ESD wrist strap or similar individual grounding device when handling X2 transceivers or coming into contact with modules.
X2 Transceiver Maintenance Guidelines
To properly maintain X2 transceivers, follow these guidelines:
•To prevent ESD damage, follow normal handling procedures.
•When the transceiver is stored or when a fiber-optic cable is not plugged in, always keep plugs in the optical bores.
•The most common source of contaminants in the optical bores is debris picked up on the ferrules of the optical connectors. Use an alcohol swab or Kim-Wipe to clean the ferrules of the optical connector.
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051SFP Guidelines
The Supervisor Engine 6L-E has two X2 ports that can support Cisco TwinGig modules providing two SFP connections to other network devices. You can have a total of four SFPs.
For installation information, refer to the Cisco SFP and SFP+ Transceiver Module Installation Notes.
Use only Cisco SFP modules on your Cisco device. Each SFP module has an internal serial EEPROM that is encoded with security information. This encoding provides a way for Cisco to identify and validate that the SFP module meets the requirements for the device.
For supported SFP transceiver media types, refer to:
Fiber-Optic Connectors
Fiber-optic cable connectors can be damaged by improper cleaning and connection procedures. Dirty or damaged fiber-optic connectors can result in communication that is not repeatable or inaccurate.
Fiber-optic connectors differ from electrical or microwave connectors. In a fiber-optic system, light is transmitted through an extremely small fiber core. Because fiber cores are often 62.5 microns or less in diameter, and dust particles range from a tenth of a micron to several microns in diameter, dust and any contamination at the end of the fiber core can degrade the performance of the connector interface where the two cores meet. Therefore, the connector must be precisely aligned, and the connector interface must be absolutely free of trapped foreign material.
Connector loss, or insertion loss, is a critical performance characteristic of a fiber-optic connector. Return loss is also an important factor. Return loss specifies the amount of reflected light; the lower the reflection, the better the connection. The best physical contact connectors have return losses greater than -40 dB, although -20 to -30 dB is more common.
The connection quality depends on two factors: the type of connector and the proper cleaning and connection techniques. Dirty fiber connectors are a common source of light loss. Keep the connectors clean at all times, and keep the dust covers installed when the connectors are not in use.
Before installing any type of cable or connector, use a lint-free alcohol pad from a cleaning kit to clean the ferrule, the protective white tube around the fiber, and the end-face surface of the fiber.
As a general rule, whenever there is a significant, unexplained loss of light, clean the connectors.
Caution Use extreme care when removing or installing connectors so that you do not damage the connector housing or scratch the end-face surface of the fiber. Always install protective covers on unused or disconnected components to prevent contamination. Always clean fiber connectors before installing them.
To clean the optical connectors, use a CLETOP cassette cleaner (type A for SC connectors or type B for MT-RJ connectors) and follow the product directions. If a CLETOP cassette cleaner is not available, follow these steps:
Step 1 Use a lint-free tissue soaked in 99 percent pure isopropyl alcohol to gently wipe the faceplate. Wait five seconds for the surfaces to dry, and repeat.
Step 2 Remove any residual dust from the faceplate with clean, dry, oil-free compressed air.
Warning Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or view directly with optical instruments. Statement 1051Step 3 Use a magnifying glass or inspection microscope to inspect the ferrule at an angle. Do not look directly into the aperture. Repeat the process if any contamination is detected.
The connectors used inside the system have been cleaned by the manufacturer and connected to the adapters in the proper manner. The operation of the system should be error free if the customer provides clean connectors on the application side, follows the previous directions, and follows these guidelines:
•Clean the connectors using either a CLETOP cassette cleaner (Type A for SC connectors and Type B for MT-RJ connectors) or lens tissues before connecting to the adapters. Use pure alcohol to remove contamination.
•Do not clean the inside of the connector adapters.
•Do not use force or quick movements when connecting the fiber-optic connectors in the adapters.
•Cover the connectors and adapters to keep the inside of the adapters or the surface of the connectors from getting dirty when you are not using the connectors or while you are cleaning the chassis.
