INSTALLING THE CONCENTRATOR MODULE

3-4

3. Secure the module to the MMAC by tightening the knurled

knobs. Failure to firmly secure the MIM may result in improper
operation.

4. Power on the MMAC chassis by plugging the AC power cord

into the wall outlet.

CONNECTING LOBE CABLING

When connecting a fiber optic link segment keep the following in
mind:

•

When connecting a fiber optic link segment with ST connectors,
keep in mind that ST connectors attach to ST ports much like
BNC connectors attach to BNC ports. The connector is inserted
into the port with the alignment key on the connector inserted
into the alignment slot on the port. The connector is then turned
to lock it down.
