Switch Control Board SRX5K-SCB Overview

The Switch Control Board (SCB) provides the following functions:
Powers on and powers off IOCs and SPCs
Controls clocking, system resets, and booting
Monitors and controls system functions, including fan speed, board power status, PDM status and
control, and the system front panel
Provides interconnections to all the IOCs within the chassis through the switch fabrics integrated into
the SCB
When the SCB is part of a host subsystem, the Routing Engine installs directly into a slot on the SCB (see
Figure 24 on page 65).
