Table 2-18 Channelized T3 line card LEDs

LED Description

Online When lit, this green LED indicates that the line card is online and is ready to receive,

process, and send data if configured to do so.

Offline When lit, this amber LED indicates that the line card is offline (powered off) and is ready

for hot swap.

The Offline LED also is lit briefly during a reboot or reset of the RS and goes out as soon

as the Control Module discovers and properly initializes the line card.
