The Routing and Control Board (RCB) is an integrated board and a single field-replaceable unit (FRU) that
provides Routing Engine and Control Board (CB) functionality. The Routing Engine performs all
route-processing functions, whereas the CB performs chassis control and management plane functionality.
The RCB provides control plane functions. You can install one or two RCBs on the router. Each RCB
functions as a unit.

The PTX10004 Routing and Control Board (RCB) is responsible for system management (see
Figure 23 on page
63). The chassis can run with one or two RCBs. We ship the base configuration with
one RCB, and you can expand the configuration with a second RCB for a fully redundant system. When
two RCBs are installed, one functions as the primary RCB and the second as a backup. If the primary RCB
is removed, the backup RCB becomes the primary if graceful Routing Engine switchover (GRES) is configured.
PTX10004 routers support the following Routing Engines for systems running standard Junos OS.
The following RCBs run on PTX10004 systems:
