RPR/SRP Uplink Card LEDs
Information on both uplink card specific LEDs and system LEDs for the RPR/SRP uplink cards is
located in this section.
The LEDs located on the left side of the RPR/SRP uplink card provide RPR and SRP uplink status
information. See Figure 5-2 and Table 5-4. The system LEDs are located on the right side of the
RPR/SRP uplink card. See Table 5-5.
Figure 5-2 RPR/SRP Uplink Status LEDs
Note Note that the RPR/SRP uplink card uses the label “PROTECT” instead of “WRAP”, and the positions of
these two LEDs are different from that on the DPT or POS/DPT uplink card.
