10/100/1000BASE-T Ports

The switch contains eight RJ-45 ports that operate at 10 Mbps or 100 Mbps, half or 
full duplex, or at 1000 Mbps, full duplex. Because all ports on the switch support 
automatic MDI/MDI-X operation, you can use straight-through cables for all network 
connections to PCs or servers, or to other switches or hubs. (See “1000BASE-T Pin 
Assignments” on page B-3.)

Each of these ports support auto-negotiation, so the optimum transmission mode 
(half or full duplex), and data rate (10, 100, or 1000 Mbps) can be selected 
automatically. If a device connected to one of these ports does not support 
auto-negotiation, the communication mode of that port can be configured manually.

SFP Slot

The Small Form Factor Pluggable (SFP) transceiver slot is shared with RJ-45 Port 8. 
If an SFP transceiver (purchased separately) is installed in the slot and has a valid 
link on its port, the associated RJ-45 port is disabled and cannot be used.

Port and Power Status LEDs

The switch includes a display panel for key system and port indications that simplify 
installation and network troubleshooting. The LEDs, which are located on the front 
panel for easy viewing, are shown below and described in the following tables.
