Removing and Installing a PRP
You must remove the PRP-2 before you can install or remove the compact flash disk or the hard disk
Note
drive. See the
information.
Removing a PRP
When you remove a PRP from a slot, be sure to use the ejector levers, which help to ensure that the PRP
is fully dislodged from the backplane connector. A PRP that is only partially removed from the
backplane can halt the system. (See
Caution Before you replace the PRP, back up the running configuration to a TFTP server or a Flash disk so that
you can retrieve it later. If the configuration is not saved, it will be lost and you will have to reenter the
entire configuration manually. This procedure is not necessary if you are temporarily removing a PRP;
lithium batteries will retain the configuration in memory until you replace the PRP in the system.
