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 5 on page
