TROUBLESHOOTING - INSTALLATION
•
During installation, first test the fiber and `twisted-pair connections with all
troubleshooting features disabled, then enable these features, if desired, just
before final installation. This will reduce the features’ interference with
testing.
•
When working with units where the features cannot be disabled, establish
both the `twisted-pair and fiber connections before the link LEDs will light.
•
To test a iMcV-LIM by itself, first have an appropriate fiber patch cable, then
follow these steps to test:
1. Connect the iMcV-LIM to the `twisted-pair device with a `twisted-pair
cable.
2. Loop a single strand of fiber from the transmit port to the receive port of
the iMcV-LIM.
3. Verify that both the `twisted-pair and the fiber link are lit (see LEDs,
below) on the iMcV-LIM.
4. Use the appropriate `twisted-pair cable, and have the crossover/pass-
through switch set correctly.
5. Whenever possible, set the devices connected to the iMcV-LIM (hub,
switch, NIC card) to the desired speed and Duplex setting, and turn
Auto Negotiation OFF. Refer to Auto Negotiation on iMcV-LIM, also
configure the devices on the opposite sides of the iMcV-LIM to operate
at the same speed and Duplex setting.
NOTE
: Some 10/100 devices cannot be set by the end user, and must Auto Negotiate to receive a signal.
