Replace a Route Processor Card
The router supports up to two redundant route processor cards. When two route processor cards are installed
in the router, one acts as an active card and the other as the standby card. When the active route processor
card is removed, the router automatically makes the standby route processor card active and the card that you
are removing, the standby route processor. If the router has only one route processor card installed, a new
route processor can be installed in the empty route processor slot during operation.
Statement 1029—Blank Faceplates and Cover Panels
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.
Warning
Statement 1034—Backplane Voltage
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when
servicing
