LEDs

There are twelve LEDs on the 3160/3164 DSU/CSU front panel (Figure 3-6) as well as on the 3161 DSU/CSU faceplate. The five LEDs on the right are shared between the DSX-1 Drop/Insert port and the data ports. Refer to the Selecting the DSX-1 or a Port for LED Display section later in this chapter to choose which port's status the LEDs display.

A green LED indicates normal operation. A yellow LED indicates a warning (for the DSX-1 Drop/Insert port) or activity (for the data ports). Conditions are sampled every tenth of a second.
