FRU
Type
Routing and Control Boards
(RCBs)
Redundant configuration:
•
Primary RCB is hot-pluggable.
•
Backup RCB is hot-insertable and hot-removable.
Base configuration:
Removal of the RCB causes the router to shut down. To prevent traffic
disruption, take the chassis offline. If a temporary disruption is acceptable, you
can install a replacement RCB in the second slot. The system restarts to elect a
primary RCB and a backup RCBs If necessary, you can manually switch the
primary and backup RCB using the
request chassis routing-engine master
switch
command.
Switch Fabric Boards (SFBs)
SFBs are hot-insertable and hot-removable. We recommend that you take
SFBs offline before removing them to avoid traffic loss while the router fabric
is being reconfigured. Use the following command:
request chassis sfb slot
slot-number
offline
Line cards
Hot-insertable. We recommend that you take line cards offline before
removing them. Use the following command:
request chassis fpc slot
slot-number
offline
Optical transceivers
Hot-insertable and hot-removable.
NOTE: Line cards are not part of the base or redundant configuration. You must order them
separately.
