Routing and Control Board

The Routing and Control board (RCB) (see Figure 4 on page 29) contains a Routing Engine and is responsible
for the system management and system control in the PTX10008. See "PTX10000 Routing and Control
Board Description" on page 78. RCBs are FRUs that are installed in the front of the chassis in the slots
labeled CB0 and CB1. The base configuration has a single RCB. The fully redundant configuration has two
RCBs. The RCB also contains Precision Time Protocol (PTP) ports and four Media Access Control Security
(MACsec) capable ports. See "PTX10008 Components and Configurations" on page 35.
