10/100/1000 Mbps Port LEDs
Each of the 10/100/1000 Mbps ports has two LEDs associated with it to
indicate port status and speed.
The optical 100/1000 Mbps ports are located in a row along the center of the
chassis and are labeled Ports 1 to 8 on the faceplate. The LEDs are located
at the bottom of the SFP connectors and are labeled LNK/ACT and SPD. See
Figure 5-5.
The copper 10/100/1000 Mbps ports are Ports 1 to 4 on the far left of the
faceplate of the chassis. These ports also have two LEDs associated with
each port, either below or above the connector. See Figure 5-5. The LEDs are
unlabeled but have the same function as the LEDs on the optical ports. This
makes the left LED the LNK/ACT, and the right LED the SPD indicator.
