The following illustration shows the items that you need to install the controller in the rack cabinet. If any items are missing or damaged, contact your place of purchase.

Note Some items come with the controller, not in the rack installation kit.

Note Use cage bars with square-holed racks, clip nuts with round-holed racks, and your own screws or the screws provided in this kit with threaded-hole racks.

Note If the slide rails in your rack installation kit came with shipping thumbscrews, remove them before you begin the following installation procedure.

Step 1 Select an available 1U space in your rack to install your controller. If you have either a round-holed or square-holed rack, install cage bars or clip nuts in the middle and the bottom (optional for the upper) holes of the lower U on each side of the front of the rack. Then, install cage bars or clip nuts in the upper and the bottom holes of the lower U on each side of the rear of the rack.

Step 2 Use a screwdriver to install the cage bars or the clip nuts on the inside of the mounting rail, as required for your rack, into the selected holes.

Step 3 The rail depth can be adjusted from 17 in (432 mm) to 31.25 in (794 mm). To adjust the depth, you can loosen the nuts on the posts and slide the bracket until the distance between the front and rear slide rail flanges matches the distance between the front and rear EIA rails of the rack cabinet. If you need further adjustment, remove the nuts, move the bracket to the appropriate set of posts (A, B, C, and D) to obtain the appropriate slide rail depth, then reinstall and tighten the nuts.

Step 4 To remove the support bracket, remove the screw (1) and remove the bracket (2) from the rear of the slide rail.

Step 5 To remove the mounting brackets, remove the screws (1) and (3). Slide out the brackets (2) and (4) from the rear of the slide rail.

Step 6 Attach the front of the slide rail and EIA latch to the front of the rack cabinet by installing a screw in the bottom hole of the lower U; then, install another screw in the middle hole of the lower U to attach the front of the slide rail to the front of the rack cabinet.

Note When you fasten the slides to the rack, ensure the screws are engaged but the flange can move slightly. You will use a screwdriver to fully tighten them in Lift the locking levers (1) on the slide rails and push the controller (2) all the way into the rack until it clicks into place..

Note Use 12-24 screws (not hex head M6 screws) on the front mounting bracket if you are installing this system into a rack with round or square holes (i.e., not threaded holes).

Step 7 Use two screws to attach the rear of the slide rail to the rear of the rack cabinet in the upper and the bottom holes of the lower U.

Repeat The rail depth can be adjusted from 17 in (432 mm) to 31.25 in (794 mm). To adjust the depth, you can loosen the nuts on the posts and slide the bracket until the distance between the front and rear slide rail flanges matches the distance between the front and rear EIA rails of the rack cabinet. If you need further adjustment, remove the nuts, move the bracket to the appropriate set of posts (A, B, C, and D) to obtain the appropriate slide rail depth, then reinstall and tighten the nuts. through Use two screws to attach the rear of the slide rail to the rear of the rack cabinet in the upper and the bottom holes of the lower U. to install the other slide rail into the rack.

Step 8 Pull the slide rails forward (1) until they click, two times, into place. Carefully lift the controller and tilt it into position over the slide rails so that the rear nail heads (2) on the controller line up with the rear slots (3) on the slide rails. Slide the controller down until the rear nail heads slip into the two rear slots, and then slowly lower the front of the controller (4) until the other nail heads slip into the other slots on the slide rails. Make sure that the front latch (5) slides over the nail heads.

Step 9 Lift the locking levers (1) on the slide rails and push the controller (2) all the way into the rack until it clicks into place.

Slide the system in and out twice to make sure the system slides correctly. Push the system inwards to the rack as close as possible but able to access the screws with a screwdriver. Then tighten the screws with a screwdriver.

Step 10 Slide the controller into the rack until it snaps into place. To slide the controller out of the rack, press on the release latches (1).

Note When you move the rack cabinet, or if you install the rack cabinet in a vibration-prone area, insert the optional M6 screws (2) in the front of the controller.

Cisco 8510 Wireless Controller Power Features

Specific steps to power-on the Cisco 8510 Wireless Controller are provided in Powering On the Controller.

When the controller is connected to an AC power source, or a DC power for source for the AIR-CT85DC-K9, but is not turned on, the operating system does not run, and all core logic except for the service processor (the Integrated Management Module) is shut down; however, the controller can respond to requests to the service processor, such as a remote request to turn on the controller. The power-on LED flashes to indicate that the controller is connected to power but is not turned on.

Turning on the Cisco 8510 Wireless Controller

Approximately 5 seconds after the controller is connected to power, one or more fans might start running to provide cooling while the system is connected to power, and the power-on button LED will blink quickly. Approximately 20 to 40 seconds after the controller is connected to power, the power-control button becomes active (the power-on LED will blink slowly), and one or more fans might start running to provide cooling while the controller is connected to power. You can turn on the controller by pressing the power-control button.

If a power failure occurs while the controller is turned on, the system will restart automatically when power is restored.

Turning off the Cisco 8510 Wireless Controller

When you turn off the controller and leave it connected to power, it can respond to requests to the service processor, such as a remote request to turn on the controller. While the controller remains connected to power, one or more fans might continue to run. To remove all power from the controller, you must disconnect it from the power source.

Caution The power control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.

The integrated management module (IMM) can turn off the controller as an automatic response to a critical system failure.

Safety Information

To install the DC power supply, complete the following steps:

Step 1 If the controller is operating, turn off the server and peripheral devices.

Step 2 Turn off the circuit breaker for the DC power source to which the new power supply will be connected. Disconnect the power cord from the DC power source.

Step 3 Attach the DC power cable to the new power supply.

Step 4 Connect the other ends of the DC power cable to the DC power source. Cut the wires to the correct length, but do not cut them shorter than 150 mm (6 in.). If the power source requires ring terminals, you must use a crimping tool to install the ring terminals to the power cord wires. The ring terminals must be UL approved and must accommodate the wires that are described in Note 1. The minimum nominal thread diameter of a pillar or stud type of terminal must be 4 mm; for a screw type of terminal the diameter must be 5.0 mm.

Step 5 Turn on the circuit breaker for the DC power source to which the new power supply is connected.

Step 6 Make sure that the green power LEDs on the power supply are lit, indicating that the power supply is operating correctly.

Connecting the AC Version of the 8510 [AIR-CT8510-K9] to a Power Source

When you apply AC power to a controller, the bootup script initializes the operating system and its stored configurations. You are prompted to enter a user ID and password and enter key configuration details.

Follow these steps to power up the controller.

Step 1 Plug an AC power cord into the back of the two power supplies (Figure 1-6). If only one power supply is connected to a power source, the system will still function correctly but the monitoring components of the controller will detect the absence of the second power supply and will raise an alarm. Connect the other end of the power cord to a properly grounded 100 to 240 VAC 50/60 Hz electrical outlet.

The end of the power cord that plugs into the controller conforms with the IEC 320 standard.

Step 2 Use the front-panel Power On/Standby button, located in the operator information panel, to turn the controller on (Figure 1-3).

Step 3 At the login prompt, enter the controller operating user ID and password. The default user ID is root and the default password is password.

The user ID and password are case sensitive.

You are now logged into the controller operating system.

Continue to the “Running the Bootup Script and Power-On Self Test” section.

Connecting the DC Version of the 8510 [AIR-CT85DC-K9] to a Power Source

1. It is the customer's responsibility to supply the necessary power cable to connect the DC power supplies to a DC power source.

To reduce the risk of electric shock or energy hazards:

– Use a circuit breaker that is rated at 25 amps.

– Use 2.5 mm ² (12 AWG) at 90° C copper wire.

– Torque the wiring-terminal screws to 0.62 newton-meters (5.5 inch-pounds).1-35

2. If the power source requires ring terminals, you must use a crimping tool to install the ring terminals to the power cord wires

Running the Bootup Script and Power-On Self Test

When you plug the controller into an AC power source, the bootup script initializes the system, verifies the hardware configuration, loads its microcode into memory, verifies its operating system software load, and initializes itself with its stored configurations. Before performing this test, you should connect your terminal emulator application to the controller’s CLI console as described in the “Connecting and Using the CLI Console” section. Follow these steps to run the bootup script and conduct the power-on self test (POST).

Step 1 Plug an AC power cord into the back of the controller and connect the other end to a grounded 100 to 240 VAC, 50/60 Hz electrical outlet. Be sure to connect both power supplies to a power source.

Step 2 Turn on the power supply.

Step 3 Observe the bootup on the CLI screen.

The bootup script displays operating system software initialization (code download and POST verification) and basic configuration as shown in the following sample bootup display:

Step 4 If desired, press Esc to display the Bootloader Boot Options menu.

Note Enter 1 to run the current software, enter 2 to run the previous software, or enter 4 to run the current software and set the controller configuration to factory defaults. Do not choose the other options unless directed to do so.

Step 5 The rest of the process takes two to three minutes. Do not reboot the controller until the user login prompt appears.

Step 6 If the controller passes the power-on self test, the bootup script runs the Startup Wizard, which prompts you for basic configuration input.

Logging into the Controller

Follow these steps to log into the controller.

Step 1 Enter a valid username and password to log into the controller CLI.

Note The administrative username and password you created in the Startup Wizard are case sensitive.

Step 2 The CLI displays the root level system prompt:

The system prompt can be any alphanumeric string up to 31 characters. You can change it by entering the config prompt command.

Note The CLI automatically logs you out without saving any changes after 5 minutes of inactivity. You can set the automatic logout from 0 (never log out) to 160 minutes using the config serial timeout command.

Note Cisco Aironet lightweight access points do not connect to the Cisco 8510 Wireless Controller if the date and time are not set properly. Set the current date and time on the controller before allowing the access points to connect to it.

Verifying Interface Settings and Port Operation

Follow these steps to verify that your interface configurations have been set properly and the controller’s ports are operational.

Step 1 Enter show interface summary. The controller’s current interface configurations appear:

Step 2 Enter show port summary. The following information appears, showing the status of the controller’s distribution system ports, which serve as the data path between the controller and Cisco lightweight access points and to which the controller’s management interface is mapped.

A link status of Up indicates that the controller’s ports are fully operational.

Connecting the Network (Distribution System)

The SFP+ module supported by the Cisco 8510 Wireless Controller is the Cisco SFP-10G-SR.

Cisco SFP-10G-SR: The Cisco 10GBASE-SR Module supports a link length of 26m on standard Fiber Distributed Data Interface (FDDI)-grade multimode fiber (MMF). Using 2000 MHz*km MMF(OM3), up to 300m link lengths are possible.

Depending on the distribution system physical port to be assigned, use only standard compliant fiber-optic cables to connect the network equipment to the controller

Note Only connections with patch cords with PC or UPC connectors are supported. Patch cords with APC connectors are not supported. All cables and cable assemblies used must be compliant with the standards specified in the standards section.

Connecting the Controller’s Service Port (Optional)

The service port is controlled by the service-port interface and is reserved for out-of-band management of the controller and system recovery and maintenance in the event of a network failure. The service-port interface enables the controller to be managed on an interface different from the one used for your network traffic. Use of the service port is optional.

You can perform out-of-band controller management from a PC running a terminal emulation program or a PC running Cisco WCS, a network management tool that enables you to configure and monitor a network of controllers, or the controller GUI. However, you must first connect the PC to the controller’s service port in one of two ways:

• Use an Ethernet cross-over cable to connect the PC directly to the controller’s service port.
• For a remote connection (using Telnet or SSH) through a dedicated management network, use a Category 5, Category 5e, Category 6, or Category 7 Ethernet cable to connect the management network to the controller’s service port and the appropriate cable to connect the PC to the management network.

Connecting Access Points

After you have configured the controller, use Category-5, Category-5e, Category-6, or Category-7 Ethernet cables to connect Cisco lightweight access points to the network.

As soon as the controller is operational, it starts to scan for access points. When it detects an access point, it records the access-point MAC address in its database. The controller radio resource management (RRM) feature then automatically configures the access point to start sending and allowing clients to associate.

You have prepared the controller for basic operation. Refer to the Cisco Wireless LAN Controller Configuration Guide for information on configuring the controller to meet the specific needs of your wireless network.
