The status LEDs on an AC PEM provide information about the current operational
status of the power supply:
PWR OK (green)—Indicates that the power supply module is operating
•
normally.
FAULT (yellow)—Indicates that a fault is detected within the PEM.
•
•
TEMP (yellow)—Indicates the PEM is in an overtemperature condition and
shutdown has occurred.
ILMI (yellow)—Indicates the PEM is operating in a current-limiting
•
condition.
For additional information about troubleshooting AC PEMs, see the
"Troubleshooting an AC Power Supply" section on page
A DC-input power subsystem consists of a DC-input power shelf that houses 4
DC PEMs that provide full redundant power to the router.
DC-input power shelf.
The chassis is electrically divided between the PEMS. These sections are referred
to as power zones and are labeled accordingly:
Two PEMs power the upper card cage (Zone 1)
•
Two PEMs power the lower card cage (Zone 2)
•
Each zone provides power to one blower, one alarm card, line cards and route
processor cards.
Zone 2 also supplies power to all switch fabric cards. The result is that there is
less power available for line cards in Zone 2, limiting the number of high-powered
line cards that can be configured in the lower cage.
To ensure that the chassis configuration complies with the required power
budgets, contact your sales representative to provide you with the required power
calculator. Failure to properly verify the configuration may result in an
unpredictable state if one of the power units fails.
Contact your local sales representative for assistance.
