Installing the Cisco
NCS 2015 Door and Other Modules
This chapter
describes how to install the NCS 2015 door and other modules.
The sections are:
Front Door
The front door of NCS
2015 provides access to the shelf, fiber-routing tray, fan-tray assembly, and
LCD screen.
There are two types
of front doors that act as protective panels—standard door and deep door. The
deep door provides additional space in front of the shelf to accommodate cables
that do not fit inside the standard door. The deep door has a hinge and can be
rotated like the standard door.
The laser warning
label is placed on the rear of the chassis.

External Connection
Units
The NCS 2015 external
connection unit (ECU) is a replaceable module that provides interfaces for
passive device inventory and management, multishelf management, and element
management. The ECU module available for the NCS 2015 shelf is NCS2015-ECU and
is installed in slot 18 of the NCS 2015 shelf.
The ECU contains
RJ-45 and SFP interfaces or multishelf and element management. Fourteen USB
ports connect to passive devices, two of which are USB 3.0 ports. A backup
flash memory is fitted into the ECU to support the database (DB) and image
backup in the operation of the NCS 2015.
The ECU contains two LEDs that indicate the link and activity status of
the optical EMS SFP port.

The ECU cannot be
pre-provisioned in CTC. After the ECU is physically plugged into Slot 18 of the
NCS 2015 shelf, the unit is detected by CTC and all the entities of the ECU
such as the USB ports, RJ-45 ports, and the optical pluggable ports are created
in CTC. In the ECU card view in CTC, only the pluggable ports are visible. The
ECU card view displays the Alarms, Conditions, History, Provisioning and
Maintenance sub-tabs. All the values in these sub-tabs, except for the port
name, are display only. Performance monitoring is not supported on the
pluggable FE ports of the ECU. The MS-ISC (RJ-45) ports are displayed in the
CTC ECU card view > Provisioning > Alarm Profiles > Alarm Behavior
tab. The IMPROPRMVL alarm is raised in CTC when the ECU is removed from the NCS
2015 shelf. The ECU entities and the ECU card view in CTC remain as they are,
even though the ECU has been removed from the NCS 2015 shelf. The ECU cannot be
deleted in CTC.
The Fiber Shuffle or
the CDC fan out unit can be connected to the NCS 2015 ECU using the USB 3.0
port.
Passive Unit Inventory Interfaces
The passive unit inventory interfaces (USB ports) are used to retrieve inventory information from passive devices such as
fiber trays, FBG DCU, patch panels, passive multiplexer or demultiplexer, and so on. There are 14 USB (12 USB 2.0 ports and
two USB 3.0 ports.) ports on the NCS 2015 ECU. The inventory details are displayed in the Inventory tab in CTC.
MSM
The multishelf management (MSM) port is an RJ-45 or SFP port that is used to connect the NCS 2015 shelf to other NCS 2015
or NCS 2015 shelves that are a part of the multishelf configuration. There are six MSM ports on the NCS 2015 ECU module.
Three MSM ports (one RJ-45 port and two SFP ports) are prefixed with M and correspond to the TNCS card in Slot 1. The other
three MSM ports (one RJ-45 port and two SFP ports) are prefixed with P and correspond to the TNCS card in slot 17. The SFP
modules must be plugged in for using the optical MSM ports. MSM connections between the NC and SSC can be done using RJ-45
ports, SFP ports, or both. The MSM cable connections can be created between two M-MSM-x ports or two P-MSM-x ports.
VoIP or UDC
VoIP or UDC is an RJ45 port that can be configured to support UDC or VoIP service on an NCS 2015 shelf. There are two VoIP
or UDC ports on the NCS 2015 ECU module. The UDC/VoIP-1 port is connected to the TNCS card in Slot 1 and the UDC/VoIP-2 port
is connected to the TNCS card in Slot 17. The VoIP or UDC port also supports Power over Ethernet for connecting VoIP equipments.

Power Modules
The NCS 2015 system contains pluggable and redundant power modules for AC and DC power. The AC and DC power modules cannot
be used simultaneously to power the NCS 2015 system. Each power module has three status LEDs located on the front left side
of its faceplate.
Note
At least one power module must be present in the chassis to boot up the system. The available power module is automatically
configured as the Working module. You must configure a Protection module to avoid power shortage in the chassis. Before configuring
a Protection module, ensure that the Protection module is available in the chassis.
If the Working module fails, the Protection module takes care of the shelf. If both the Protection and Working modules fail,
line cards may shut down due to power shortage and traffic is affected.

AC Power
Modules
The NCS 2015 system
is powered by AC power modules with 1+0, 1+1, 2+0, and 2+2 redundancy. The
supported AC power module on the NCS 2015 shelf is NCS4K-AC-PSU. The AC power
module converts the AC-input current to DC-output current. Each AC power module
has one AC single-phase 3 poles (line L, Neutral N, and Protective Earth PE)
input connector.
DC Power
Module
The NCS 2015 system
is powered by DC power modules with 3+1, 2+2, 2+1, and 1+1 redundancy. The
supported DC power module on the NCS 2015 shelf is NCS4K-DC-PSU-V1. The DC
power module draws power from the power plant to turn on the NCS 2015 shelf.
The PWR-CON-LMT alarm
is raised in the Alarms tab in CTC when the installation or pre-provisioning of
a card causes the power consumption to exceed the power limit.
The PWR-CON-LMT alarm
is raised on the NCS2015 shelf when the power consumption of the shelf exceeds
the maximum power limit. A database backup is performed on the shelf.
Additional power modules are installed to increase the power limit. A database
restore is then performed on the shelf. The PWR-CON-LMT alarm still persists
even though the power consumption is within the power limit.
Note
The total power
consumption of the shelf is calculated by the controller card and displayed in
CTC in the Provisioning > Power Monitor tab.
Power Filler Module
For redundant power supplies, four AC or DC power modules can be installed in the NCS 2015 shelf. However, only one power
module can sustain the functioning of the entire NCS 2015 system. You can install power filler modules in the empty slots.

LCD Unit
The LCD unit is integrated with the fan tray assembly and consists of an LCD display panel, push button, and shelf-level LED
indicators on the NCS 2015 system.
The shelf controller card (TNCS) powers the 16 x 2 character LCD screen. The LCD screen displays the shelf name, shelf IP
address, and software version currently used. The LCD screen also provides slot-level and port-level information of all card
slots, including the number of critical, major, and minor alarms. The display contrast is automatically adjusted for a clearer
view. The three accessible push buttons (SLOT, STATUS, and PORT) on the LCD unit are used to set parameters at the slot-level
and port-level. There are three alarm LEDs (CRIT, MAJ, and MIN) on the LCD unit that indicate whether a critical, major, or
minor alarm is present anywhere on the NCS 2015 shelf. There is also a Fan Fail LED. When the fan-tray assembly is not functioning
or when the power line is not connected, the LED is OFF. When the power line is connected and if there is no TNCS card installed
in the NCS2015 shelf, then the LED is OFF. A red LED indicates an alarm in the fan-tray assembly. A green LED indicates that
the fan-tray assembly is functioning, the power line is connected, and the power module is functioning properly. The shelf
controller card controls the conditions that result in triggering the LEDs. The LEDs can be overwritten by the shelf controller
card (TNCS) in all the three states (OFF/red/green). The LCD unit supports the lamp test procedure and the LEDs changes its
color or state.
Fan-Tray Assembly
The fan-tray supported on the NCS 2015 shelf is NCS2015-FTA.
The fan-tray assembly is located on the front side of the NCS 2015 shelf. The fan-tray is removable and holds the fan-control
circuitry and the fans for the NCS 2015 shelf. The fan tray has 9 x 92mm x 48mm fans that are capable of pulling enough air
to cool up to 300 W per LC with optimum placement and components at both 27C NEBS acoustic level and 55C NEBS extended temperature
range. The fan tray also accommodates LCD panel and its circuitry. The fan-tray assembly supports the lamp test procedure.
After you install the fan tray, you should only access it when a fan failure occurs.
Fan Speed
The fan speed is controlled by the TNCS card temperature sensors. The sensors measure the input air temperature at the fan-tray
assembly. If the TNCS card fails, the fans automatically shift to high speed. The temperature that the TNCS sensors measure
appears on the LCD screen.
Fan Failure
If one or more fans fail on the fan-tray assembly, replace the entire assembly. You cannot replace individual fans. The FAN-DEGRADE
alarm is raised when one fan fails and the Fan Fail LED in the LCD unit glows with amber color. The FAN-FAIL alarm is raised
when two or more fans fail and the Fan Fail LED glows with red color. The Fan Fail LED clears after you install a working
fan-tray.
NTP-L54 Installing
Fan-Tray Assembly in NCS 2015 Shelf
Purpose
This
procedure installs the NCS2015-FTA fan-tray assembly in the NCS 2015 system.
Do not operate an
NCS 2015 chassis without the fan tray for more than two minutes.
Warning
Do not
reach into a vacant slot when installing or removing the fan tray. Exposed
circuitry is an energy hazard. Statement 206
Caution
When the fan tray
is removed, shock hazard is possible. Do not introduce any object into the fan
tray slot nor touch the empty slot. Install the fan tray immediately.
Caution
Do not force a

Stop. You have completed this procedure.
Air Filter
The NCS 2015 contains a preinstalled disposable air filter (NCS2015-FTF) on the bottom side of the shelf.
The disposable filter is made up of a gray, open-cell, polyurethane foam that is specially coated to provide fire and fungi
resistance. Spare filters should be kept in stock. Inspection of the air filter must be performed as specified in your local
site practices.
First inspection of the air filter should be performed six months after the system installation. Air filters must be inspected
every quarter after the initial six month inspection. If they are dirty or clogged with dust, they must be replaced with a
new air filter.
Caution
Do not operate an NCS 2015 without the mandatory air filter.
