– The 5V MBus power supply has been integrated onto the CSF permitting
the use of generic PEMs in the chassis. The Cisco XR 12404 router can
monitor for the PEM for these conditions:
• The operational status
• Output voltage
• Output current.

– The alarm output function is controlled by the software on the route
processor. When a signal is received from the route processor the alarm
MBus module on the CSF card activates specific LEDs to signal a
