Modular Configuration Ac Power - Cisco CRS-1 System Description

Cisco CRS 8-Slot Line Card Chassis Enhanced Router Power Systems
Name
Internal Fault
The Internal Fault LED on the DC power module is turned on continuously to indicate that one or more of
the following internal faults is detected inside the power module:
• 5V out of range
• Output Stage OT
• Fan Fault
• OR-ing fault (Output voltage less than bus voltage)
• OC shutdown
• OT shutdown
• OV shutdown
• Input stage OT
• Fault induced shutdown occurred
• Thermal sensor fault
• Vout out of range
• Boost Vbulk fault
Once all of the faults have been removed and the power module is operating normally, the Internal Fault LED
is turned off.

Modular Configuration AC Power

The Cisco CRS 8-slot Line Card Chassis Enhanced router modular configuration AC power system can provide
up to 9,000 W to power the Cisco CRS 8-Slot Line Card Chassis Enhanced router.
Note
Depending on the hardware deployed at your site, your system may not consume the maximum power supplied
by the power system.
The modular configuration power system provides the following features:
• AC power shelf redundancy
• PM load-share redundancy
• Elimination of power zone distribution, while maintaining zone protection
• Capacity for future growth
The modular configuration AC power systems use A and B power shelves to provide reliable, 2N redundant
power to all chassis components.
The Cisco CRS 8-slot Line Card Chassis Enhanced router does not contain an alarm module. The AC PM
monitors PM status and processes alarm functions. The AC PM distributes power and passes PM status signals
to the system. Each PM has its own integrated fuse to protect the system, and each PM is plugged into its own
power outlet. Alarms are processed through the RP. LEDs on the front panel of the RP indicate active alarm
conditions.
The modular configuration AC power system requires single-phase AC input power. If you have 3-phase AC
Delta or AC Wye at your equipment, a Cisco CRS PDU will be required to convert 3-phase AC input power
to single-phase AC input power for the power shelf. For further information, refer to the
Color Function
Red Internal Fault LED turns on continuously when there is an internal fault in the power
module.
