Verifying the Installation
The procedure in this section has you test the unit by performing a link test. A
link test will determine whether each fiber optic port on the unit is receiving a
signal from the node connected to it. You should perform this test immediately
after you have installed the unit or whenever you need to test the integrity of
the fiber optic connections to the fiber optic ports on the unit. To perform a
link test, follow these steps:
1. Verify that the Main LED is a steady green, indicating that the unit is
receiving power.
2. If you installed an optional redundant power supply, check that the
BCKP LED is a steady green.
3. Check to be sure that the fans for the main power supply and the
redundant power supply, if installed, are operating.
4. Set the Link Test switch to the Test position. If you are installing an
AT-MCF12xx unit, set both Link Test switches to the Test position.
The Test LED next to the Link Test switch(es) should be amber.
Note
In order to run a link test, the nodes connected to the ports on the
multichannel media converter must be powered on and operating.
5. Check that the F-LNK LED for each fiber optic port on the unit is lit,
indicating a link exists between the fiber optic port on the multichannel
media converter and the node to which the port is connected.
6. If one or more of the F-LNK LEDs for the fiber optic ports are not lit, go to
the section “Troubleshooting” on page 23.
7. Set the Link Test switch(es) to Normal.
Note
The multichannel media converter will not pass network data when the
Link Test switch is in the Link Test position. For normal network
operations, the switch must be set to the Normal setting.
The multichannel media converter is now ready for normal network
operations. For information on the status LEDs, refer to “Status LEDs” on
page 3.
