inside the case of the unit.
CAUTION: Read the section ‘Important Safety
information’, at the start of this manual.
The OfficeConnect Remote is fully performance
tested after assembly. Providing the unit has been
correctly installed, and is used in accordance with the
instructions contained in this manual, difficulties
should not arise. If unit or system maintenance is
required, then it must be carried out by a
competent network engineer.
In the unlikely event that you experience problems
with the unit, the following procedure will enable
you to undertake basic troubleshooting before
contacting your 3Com reseller.
Malfunction Remedy
If you cannot
connect your
OfficeConnect
Remote to the
network or PC.
Verify that your computer is equipped with
an available serial port and that the correct
cables and connectors are being used. If in
doubt contact the unit’s supplier.
The POWER LED
does not light.
Confirm that:
a) The switched outlet socket of the
electrical mains system supply is turned
on. The main lead is correctly plugged
into the unit’s electrical mains system inlet
socket.
b) The switched outlet socket is ‘live’ by
plugging the unit into an alternate socket
to see if it functions.
