Removing and Replacing the RP
Cisco 12008 Gigabit Switch Router Installation and Configuration Guide

Caution Before replacing the RP with another, back up the running configuration file to a
Trivial File Transfer Protocol (TFTP) file server or an installed Flash memory card. Doing
so enables you to retrieve the file later for reuse. If you do not back up the configuration
file, it will be lost and you will have to manually reenter the configuration information for
the router. If you are temporarily removing the RP and will be reinstalling it shortly, you
need not back up the configuration file, because lithium batteries on the RP retain the
configuration file in NVRAM until the RP is reinstalled.
Removing the RP
Although Figure 7-15 appearing later in this section illustrates a RP being removed from a
Cisco 12012, the procedure for removing a RP from a Cisco 12008 is essentiall y ident ical.
For purposes of the Cisco 12008 RP removal procedure, it is assumed that the RP is
installed in slot 0 of the upper card cage.
To remove the RP from the Cisco 12008, perform the following steps:
Step1 Set the rotary power switch(es) on the ins talled power supply(ies) to the Standby
position (AC-input power supply) or the OFF position (DC-input power supply).
Step2 If you are removing the RP from the system with the intent to replace it with
another RP, copy the currently running configuration file to a TFTP server in the
network or to a Flash memory card installed in either PCMCIA slot 0 or 1.
Backing up the configuration file in this manner enables you to retrieve it later
so that it can be copied to NVRAM on the new RP.
Step3 Put on an antistatic wrist strap and make sure that it makes ample contact with
your skin. Insert the equipment end of the wrist strap (the banana jack) into the
ESD socket in the lower left corner of the upper card cage.
Step4 If you are removing the RP with the intent to upgrade its memory (and will be
reinstalling it shortly), you can leave any interface cables (for the console port,
auxiliary port, and Ethernet ports) attached to the RP, provided that doing so will
not strain the cables when you place the RP on an antistatic mat or foam pad to
perform the memory upgrade procedure.
If the interface cables are not long enough to allow you to place the RP on an
antistatic mat or foam pad without undue stress to the cables, disconnect the
cables before removing the RP and proceeding with the memory upgrade task.
