5.3 Cable Connections
The MVI71-GEC module has the following functional communication connections
installed:

One Ethernet port (RJ45 connector)

One RS-232 Configuration/Debug port (RJ45 connector)
5.3.1 Ethernet Connection
The MVI71-GEC module has an RJ45 port located on the front of the module,
labeled Ethernet, for use with the TCP/IP network. The module is connected to
the Ethernet network using an Ethernet cable between the module’s Ethernet
port and an Ethernet switch or hub.
Note: Depending on hardware configuration, you may see more than one RJ45 port on the
module. The Ethernet port is labeled Ethernet.
Warning: The MVI71-GEC module is NOT compatible with Power Over Ethernet (IEEE802.3af /
IEEE802.3at) networks. Do NOT connect the module to Ethernet devices, hubs, switches or
networks that supply AC or DC power over the Ethernet cable. Failure to observe this precaution
may result in damage to hardware, or injury to personnel.
Important: The module requires a static (fixed) IP address that is not shared with any other device
on the Ethernet network. Obtain a list of suitable IP addresses from your network administrator
BEFORE configuring the Ethernet port on this module.
Ethernet Port Configuration - wattcp.cfg
The wattcp.cfg file must be set up properly in order to use a TCP/IP network
connection. You can view the current network configuration in ProSoft
Configuration Builder (PCB), as shown:
You may also view the network configuration using a PC serial port connection
and an ASCII terminal program (like Windows HyperTerminal) by selecting [@]
(Network Menu) and [V] (View) options when connected to the Debug port. For
more information on serial port access, see the chapter on Diagnostics and
Troubleshooting (page 33).
