Installing the Patch Panel on the Rack
A patch panel serves as a static switchboard, using cables to interconnect networks and manage fiber optic
cables. A patch panel uses patch cords, to create each interconnection. Circuits can also be rearranged by
plugging and unplugging respective patch cords. Patch cords connect the ports in the patch panel to ports in
the network switch, which creates permanent port connections to the switch. Patch panels are based on the
number of ports they contain, with 48-port, 24-port and 12-port panels.

Replacing the Fan Tray
The fan tray supports online insertion and removal (OIR). There is no need to power down the Cisco ASR
914 Router to remove or replace the fan tray. Only one fan tray can be removed or replaced at a time. However,
the router will shut down if the fan tray is removed for more than 5 minutes at 30º C. If more than one fan
tray is removed the system will shut down immediately. Once the thermal overload condition is absent, the
system attempts to power up automatically, if the fan tray is re-inserted and the system temperature is within
limits. Approximately at 25º C the system powers back in 2 minutes.
Do not introduce body parts or objects in the fan tray slot when installing or removing the fan tray module.
Exposed circuitry is an energy hazard.
Note
The router can stay active for up to 60 seconds if the temperature is below the ambient limit. However, in the
event of an overtemperature alarm, the router can shut down in less than 60 seconds. In the event of a critical
temperature alarm, the router shuts down immediately.
Caution
To avoid erroneous failure messages, allow at least 2 minutes for the system to reinitialize after the fan tray
has been removed or replaced.

RSP Installation
Follow the steps in the sections below on handling an RSP module in the Cisco ASR 914 Router:
Installing an RSP Module
Procedure
Step 1 Choose a slot for the RSP module. Make sure that there is enough clearance to accommodate any equipment
that will be connected to the ports on the module. If a blank module filler plate is installed in the slot in which
you plan to install the module, remove the plate by removing its 2 Phillips pan-head screws.
Step 2 Fully open both the ejector levers on the new module, as shown in the figure below.
To prevent ESD damage, handle modules by carrier edges only.
Caution
Step 3 Position the module in the slot. Make sure that you align the sides of the module with the guides on each side
of the slot, as shown in the figure below.
Figure 13: Cisco ASR 914 Router RSP Installation
Installing the Cisco ASR 914 Router

Installing the Cisco ASR 914 Router
RSP Installation

Step 4 Carefully slide the module into the slot until the EMI gasket on the module makes contact with the module
in the adjacent slot and both the ejector levers have closed to approximately 45 degrees with respect to the
module faceplate.
If the top slot already has an RSP module installed, and you install a second RSP module in the slot
below it, be careful not to damage the EMI gasket of the bottom RSP module against the ejector
levers of the top RSP during insertion.
Caution
Step 5 While pressing down, simultaneously close both the ejector levers to fully seat the module in the backplane
connector. The ejector levers are fully closed when they are flush with the module faceplate.
Step 6 Tighten the two captive installation screws on the module. The recommended maximum torque is 5.5 in.-lb
(.62 N-m).
Make sure that the ejector levers are fully closed before tightening the captive installation screws.
Note
Step 7 Verify that the captive installation screws are tightened on all of the modules installed in the chassis. This
step ensures that the EMI gaskets on all the modules are fully compressed in order to maximize the opening
space for the new or replacement module.
If the captive installation screws are loose, the EMI gaskets on the installed modules will push
adjacent modules toward the open slot, which reduces the size of the opening and makes it difficult
to install the new module.
Note
Blank module filler plates (Cisco part number A90X-RSPA-BLANK-W) should be installed in any
empty chassis slots to keep dust out of the chassis and to maintain consistent airflow through the
chassis.
Caution
When installing the cabling to an RSP, we recommend that you leave a service loop of extra cabling
sufficient to allow for fan tray removal.
Note
Removing an RSP Module
Before you remove an RSP from the router, you must save the current configuration on a TFTP server or an
external USB flash drive, using the copy running-config {ftp |tftp |bootflash:} command. This saves you
time when bringing the module back online.
If the module is running Cisco IOS software, save the current running configuration by entering the copy
running-config startup-config command.
To remove an RSP module, perform the following steps:
Procedure
Step 1 Disconnect any cables attached to the ports on the module.
Step 2 Verify that the captive installation screws on neighboring modules in the chassis are tight. This step ensures
that the space created by the removed module is maintained.
If the captive installation screws are loose, the EMI gaskets on the installed modules push the
modules toward the open slot, which in turn reduces the size of the opening and makes it difficult
to remove the module.
Note
Step 3 Loosen the two captive installation screws on the module you plan to remove from the chassis.
