DPT and POS/DPT Uplink Card LEDs

Information on both uplink card specific LEDs and system LEDs for the DPT and POS/DPT uplink cards is in this section.

The LEDs located on the left side of the DPT and POS/DPT uplink card provide DPT and POS uplink status information. (See Figure 5-1.) For POS/DPT uplink cards, the LED information is dependent on whether the card is configured as POS or DPT. (See Table 5-1and Table 5-2.)

See Table 5-3for system LED information for the DPT and POS/DPT cards.
