The Routing and Control Board (RCB) is responsible for system management in a
QFX10008 or QFX10016 (see
or two RCBs. Base configurations ship with one RCB that can be expanded with a second
RCB for a fully-redundant system. When two RCBs are installed, one functions as the
master and the second as a backup. If the master RCB is removed, the backup restarts
and becomes the master.

Routing and Control Board Functions

The RCB integrates the control plane and Routing Engine functions into a single
management unit. Each RCB provides all the functions needed to manage the operation
of the modular chassis:
System control functions such as environmental monitoring
Routing Layer 2 and Layer 3 protocols
Communication to all components such as line cards, Switch Interface Boards (SIBs),
and power and cooling
Transparent clocking
Alarm and logging functions

Routing and Control Board Components

Each RCB consists of the following internal components:
Quad-core 2.5 GHz CPU
32 GB SDRAM
50 GB or 100 GB onboard SATA SSD
Other standard interfaces are shown in
Figure 30 on page 67). The switch chassis can run with one
