Chassis Card Cages

The status LEDs on a DC 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.

For additional information about troubleshooting DC PEMs, see the “Troubleshooting a DC Power Supply” section on page 4-10.

Chassis Card Cages

There are three integral card cages in the chassis: the upper card cage, the lower card cage, and the switch fabric card cage (see Figure 1-1).

Upper Card Cage

The upper card cage has eight user-configurable slots that support a combination of line cards, an alarm card, and an RP.

•Alarm—The far left slot is a dedicated slot for an alarm card.

•Slots 0 through 6—Can be populated with any line cards supported by the router.

•Slot 7—The far right slot is reserved for the RP.
