Removing and Replacing Cards from the Chassis
This section contains the procedures to remove cards from the card cages in the
chassis. For additional information about specific types of cards, see
Chapter 1,
“Product Overview.”
Removing and Replacing RP and Line Cards from the Upper and
Lower Card Cages
This section describes the procedures for removing and installing a router
processor (RP) card or a line card from the upper or lower card cage. The upper
and lower card cages have 9 slots, and the lower card cage is a reverse image of
the top card cage. Alarm cards can only be installed in their specific slots which
are labeled as “Alarm Card”. See the
“Removing and Replacing an Alarm Card”
section on page 7-81 for information about replacing an alarm card.
Caution If you are upgrading your router from a GRP to a PRP, you must power off the
router to switch the RP cards. If you are replacing a nonredundant RP you should
back up the running configuration file to a TFTP server or a flash disk so that you
can retrieve it later. If the configuration file is not saved, you will have to reenter
the entire configuration manually for the new RP.
