Servicing Information
Opening of the case and changing of modules is only to
be performed by qualified service personnel.
WARNING !
Always disconnect the power cord from the rear panel of the bridge/router.
The bridge/router case does not need to be opened to change LAN or WAN interface
modules.
Opening the case
1) Remove power from the bridge/router and remove the other cabling.
2) Turn the bridge/router over and place it on a flat, cushioned surface.
3) Remove the six Phillips head screws that fasten the case together (4 across the front
and 1 on each rear side).
4) Hold the two halves of the case together and turn the bridge/router right-side up.
5) Lift off the top half of the case. The LEDs in the front panel of the bridge/router are
connected to the main board by a short ribbon cable. When lifting the top half of the
case off, the lid should be lifted from the back and hinged at the front. The lid will
then fold completely over and lie top down.
