For ES1100-16/24E, use the ON/OFF switch to have the Switch power on or off.

2.2 Front Panel

The front panel of the Switch includes the auto-negotiating 10 Base-T/100 Base-TX RJ-45 ports and

the LEDs.

2.2.1 RJ-45 Auto-negotiating Ports

The 10 Base-T/100 Base-TX RJ-45 ports are auto-negotiating and auto-crossover.

An auto-negotiating port can detect and adjust to the optimum Ethernet speed (10/100 Mpbs) and

duplex mode (full duplex or half duplex) of the connected device.

An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-through or crossover

Ethernet cable.

2.2.2 Front Panel Connections

You can use unshielded twisted pair (UTP) or shielded twisted-pair (STP) Ethernet cables for RJ-45

ports. The following table describes the types of network cable used for the different connection

speeds.

You can use either crossover or straight-through cables for all the ports.
