127oF [53oC] <= outlet < 167oF [75oC])

CARD FAIL

 

Red

A hardware failure is detected on the uplink card. During power up, the

 

 

 

LED will be red even when the uplink card is powered down.

POWER

 

Green (default status when

Uplink card is receiving power from the system.1

 

 

initialized)

 

 

 

 

 

 

 

Off

Uplink card is not receiving power from the system.

 

 

 

 

1.System power up is not an indication that the uplink card is powered up. Check the card status LEDs to ensure the card is functioning properly and is receiving power from the system.
