AC power cord
An AC power cords is used for connecting an AC power supply on the switch to the external AC
power supply system. Select an AC power cord with a current-carrying capacity that meets the
power supply requirement.
For a PSR1600B-12A-B power supply, use an IEC 60320 standard-compliant power cord that has a
C13 connector (connected to the power supply). For a PSR1600-54A-B power supply, use an IEC
60320 standard-compliant power cord that has a C15 connector (connected to the power supply).
The type of the connector (connected to the power source) varies by country or region. Select a
compliant connector type as needed. For the connector types of different countries or regions and
the power cord codes, see

Ethernet twisted pair cable
An Ethernet twisted pair cable consists of four pairs of insulated wires twisted together. It mainly
transmits analog signals and is advantageous in transmitting data over shorter distances. The
maximum transmission distance is 100 m (328.08 ft). To increase the transmission distance, you can
install a maximum of four repeaters between two Ethernet twisted pair cables. With four repeaters
installed, the maximum transmission distance can reach 500 m (1640.42 ft).
RJ-45 connector
An Ethernet twisted pair cable connects network devices through the RJ-45 connectors at the two
ends.

Cable pinouts
EIA/TIA cabling specifications define two standards: 568A and 568B for cable pinouts.
