Figure 6: Front-Panel LEDs
Each GLM Switch product is equipped with a common set of LEDs, as shown in Figure 6:
•
One LED for each of the two permitted power supply inputs (P1 and P2)
•
One LED for the Alarm Contact (ALM)
For each Ethernet port, there is an amber speed LED and a green Link Activity LED. The appearance is different
for the RJ45 ports (suitable for copper cables) versus the SFP connectors, as indicated in Figure 6.
