2.1.1 Rear Panel Power Connection
Connect one end of the supplied power cord to the power receptacle on the back of the Switch and
the other end to the appropriate power source.
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. Only the ES1100-24G’s front panel provides the 10 Base-T/100 Base-TX/1000 Base-T RJ-
45 ports with shared 100M/1G mini-GBIC open slots.
2.2.1 RJ-45 Auto-negotiating Ports
All the RJ-45 ports in the ES1100 series are auto-negotiating and auto-crossover.
An auto-negotiating port can detect and adjust to the optimum Ethernet speed (10/100/1000
Mbps) 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.
