Configuring and Installing Modules
IMC Networks recommends turning the chassis power off before proceeding.
1. To install an iMcV module, slide the module into the chassis until the
module is firmly seated in the backplane.
2. Secure the module to the chassis by tightening the captive thumb screw on
the iMcV module.
3. Attach the network cables between the iMcV module and other devices that
will be interconnected.
4. Connect the DC power source.
DC Power Supply Wiring Instructions
The following image shows the wiring configuration for a 48 VDC power supply in a
negative ground system application. For positive ground system applications remove
the chassis ground shorting jumper and connect it between the positive terminal and
the chassis ground terminal. Alternatively, the chassis grounding jumper can be
eliminated and the chassis ground connected at the power source.
NOTE
Incorrect wiring will result in chassis malfunction. The IE-MediaChassis/2 (DC) is
compliant with Isolated Grounding Plane practices. The POSITIVE and NEGATIVE
terminals are isolated from chassis ground and must have a ground reference at
the power-sourcing equipment.
This equipment is designed to permit the connection of the grounded conductor of
the DC supply circuit to the earthed conductor at the equipment. If this connection
is made, all of the following conditions must be met:
