Installation Troubleshooting
•
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.
•
Use the appropriate twisted pair cable, and have the crossover/pass-through
switch set correctly.
•
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 can not be set by the end user, and must Auto Ne
g
otiate to receive a
signal.
