Front-Panel LEDs
The front panel of the switch provides a link status LED for each RJ-45 port. In addition, the front
panel also contains status LEDs for “at-a’glance” system monitoring. The following table details
the functions of the various indicators:

Front-Panel Ports
The front-panel ports are multi-speed RJ-45 ports with built-in wiring crossovers. PCs can be
connected to these ports with straight-through or crossover cable. Each port supports
Auto-Negotiation, so the optimum communication mode (half or full duplex) and data rate (10 Mbps,
100 Mbps or 1000 Mbps) are selected automatically.
