After connecting the device to a power source, confirm that the device is connected and operating

correctly by examining the LEDs on the front panel.

Port Connections, Cables, and Pinout Information

This section explains the device’s physical interfaces, and provides information about port connections.

Connector types, ports and cables are summarized in Ports, Connectors, and Cables. Copper Cable and

Optical Transceiver Diagnostics are supported.

RJ-45 Connections for 10/100/1000BaseT Ports

The 10/100/1000BaseT ports are copper twisted-pair ports.

To establish a link for the twisted-pair ports, Tx pair on one cable end must be connected to the Rx pair

on the other cable end, and vice versa. If the cabling is done such that Tx on one end is wired to Tx on

the other end, and Rx is wired to Rx, a link is not established.

When selecting cables to connect the device ports to their networking peers, straight through cables must

be used to connect the device to a station, and crossover cables must be used to connect one transmission

device (switch or hub) to another. Both the straight through and crossover cables are category 5.

After a port is connected, its LINK indication LED is lit.
