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 5-2and Table 5-4. The system LEDs are located on the right side of the RPR/SRP uplink card. See Table 5-5.
