Note If the base unit has an Optical Fiber Module installed, make sure that the optical fiber test
cable is inserted in the receptacles.
The green LED will be lit next to the number of each LAM that is connected to the base unit and is operating correctly.
The yellow LED will be lit next to the number of each LAM that is defective or incorrectly connected to the base unit.
Remove the test cable from the Optical Fiber Modules, if present
Re-cable the base unit to the token-ring network
Notify the network administrator that the base unit is operational.

- Check the 4/16 Mbps switch setting on the front of the base unit.
- Be sure that the setting matches the data rate of the ring.
- Turn on the power of the IBM 8230, and wait 60 seconds.
Note : DO NOT turn off the power of the base unit unless you
are instructed to do so. Turning off the power of the base unit
will disrupt all users connected to this base unit.
