Removing An Rsp Module - Cisco ASR 903 Hardware Installation Manual

RSP Installation
Verify that the captive installation screws are tightened on all of the modules installed in the chassis.
Step 7
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.
Note
Note Blank module filler plates (Cisco part number A900-RSPA-BLANK) should be installed in any empty
chassis slots to keep dust out of the chassis and to maintain consistent airflow through the chassis.
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.

Removing an RSP Module

Before you remove an RSP from the router, you should save the current configuration using the write
{host file | network | terminal} 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.
Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution
when servicing. Statement 1034

beams or view directly with optical instruments. Statement 1051
To remove an RSP module, perform the following steps:
Step 1 Disconnect any cables attached to the ports on the module.
Step 2 Verify that the captive installation screws on all the modules in the chassis are tight. This step ensures

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.
If the captive installation screws are loose, the EMI gaskets on the installed modules will push
the modules toward the open slot, which in turn reduces the size of the opening and makes it
difficult to remove the module.
