Removing An Rsp Module - Cisco ASR 903 Installing Manual

Installing the Cisco ASR 903 Router
Note 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.
Close all unused RJ-45 and USB ports on the RSP module using the appropriate dust caps to prevent dust from

accumulating inside the cage. For information on dust caps, see

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.
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into 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 that the space
created by the removed module is maintained.
If the captive installation screws are loose, the EMI gaskets on the installed modules will push the modules
Note
toward the open slot, which in turn reduces the size of the opening and makes it difficult to remove the module.
Step 3
Loosen the two captive installation screws on the module you plan to remove from the chassis.
Step 4 Place your thumbs on the ejector levers (see the figure Cisco ASR 903 Router RSP Installation ) and simultaneously
rotate the ejector levers outward to unseat the module from the backplane connector.
Step 5
Grasp the front edge of the module and slide the module straight out of the slot. If the chassis has horizontal slots, place
your hand under the module to support its weight as you slide it out from the slot. Do not touch the module circuitry.
To prevent ESD damage, handle modules by the carrier edges only.
Caution
Step 6
Place the module on an antistatic mat or antistatic foam, or immediately reinstall the module in another slot.
Step 7 Install blank module filler plates (Cisco part number A900-RSPA-BLANK) in empty slots, if any.
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
