Rough handling during shipping can damage electronic equipment. After
you unpack the CentreCOM MAC Layer Bridge, check carefully for
possible damage. If you notice any damage, contact the shipper.
Direct any additional questions about damage to the distributor from
whom the unit was purchased, or contact Allied Telesyn:

Save the shipping carton and packing material in case you need to store or
ship the bridge back in the future.
TheCentreCOM MAC Layer Bridge should be placed in a cool, well-
ventilated area. Air vents are located on each side of the bridge. The back
of the unit also has a fan vent. It is very important that none of the air
vents are obstructed by any material, wall, or other equipment. There
should be several inches of clearance between these vents and any other
object.
Failure to follow these ventilation guidelines may result in overheating
and eventual damage of the bridge.
The CentreCOM MAC Layer Bridge is configured at the factory to use
Ethernet or IEEE 802.3 10BASE5 on both channels. If the bridge is used
in this environment, no additional configuration is required.
To use the bridge in other modes, some jumpers inside the unit must be
relocated. To do this, follow the directions below:
1. Remove the power plug.
2. Remove the two screws on each side of the bridge that hold the top cover
in place.
3. Remove the top cover. The cover fits tightly, and it may be necessary to
use a screwdriver to initially dislodge the cover.
4. If necessary, carefully remove thin-Ethernet transformers with an IC
puller or a flat screwdriver. Reposition and install the transformers at the
specified location. Check for bent pins or a shifted transformer.
5. Replace the top cover and screws.
Caution: Make sure that the power cord is removed from the bridge before
opening the cover.
