SRX5800 Services Gateway Switch Control Board Description

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 1).
