Replace a Route Processor Card
The NCS-57C3-MOD router supports up to two redundant route processor (RP) cards. When two RP cards
are installed in the router, one acts as an active card and the other as the standby card. When the active RP
card is removed, the router automatically makes the standby RP card active and the card that you are removing,
the standby RP. If the router has only one RP card installed, a new RP can be installed in the empty RP 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
