Management Port
The Management port supports half-duplex and full-duplex communication via 10/100 or
autonegotiated Ethernet. The Management port provides a channel to download software and
configuration files and to manage the system. This port has an RJ-45 connector on the front
panel. You must provide a shielded CAT5E Ethernet cable to connect to the port. Shielded
cable must be used to maintain EMC compliance.
