The LEDs are located on the front panel of the UTT 2512, see Figure 2-2. We divide the
LEDs into two groups:
Ɣ The first group includes four system LEDs on the left two columns, which indicate
power status, operational status and failures of the UTT 2512, see Table 2-1 for
detailed description.
Ɣ The second group includes the ten port LEDs on the right five columns, which
indicate the status of each port, see Table 2-2 for detailed description. Each port has
two LEDs, LEDs 1 through 4 are corresponding to LAN1 through LAN4 respectively,
and LED WAN is corresponding to WAN.
