EX-series Switch—SFP Uplink Module Port LEDs
The ports on the small-form factor pluggable transceiver (SFP) uplink module have
two LEDs. Figure 13 on page 18 shows the SFP uplink module port and the location
of the LEDs on the port.
The LEDs labeled LED 1 in Figure 13 on page 18 indicate link status, and the LEDs
labeled LED 2 in Figure 13 on page 18 indicate the status of one of the four port
parameters. The port parameters are: administrative status; duplex mode; PoE status;
and speed.
