An optional RJ45 Ethernet 10BaseT connector is located on the rear panel for remote control. A
dministrator for directions on connecting the AC source to any corporate LAN.
If the –LAN Ethernet interface option is present, the MAC Address (Media Access Control) of the
Ethernet port is printed on the serial tag of the power source. The serial tag is located on the rear
panel of the unit.
For information on how to set up a network connection or a direct PC connection using the LAN
interface, refer to the i/iX Series Programming Manual P/N 6005-961 distributed in Adobe PDF format
on CD ROM CIC496.
standard RJ45 UTP patch cord between the AC Source and a network Hub may be used to connect
the AC source to a LAN. For direct connection to a PC LAN card, a crossover RJ45 cable is required.
