Introduction
This guide describes the features and advanced configuration of the
OfficeConnectRemote 840 SDSL Router. The guide is intended for both
first-time and experienced computer network users who are using the
OfficeConnectRemote 840.
For information on the initial configuration of the unit, see the
OfficeConnect Remote 840 SDSL Router Installation Guide (included in
the box when your purchased your Router). That guide contains steps to

Safety Information
When using the unit, observe the following safety information:
Retain this user guide for later use and pass it on to subsequent
owners/managers of the unit.
The power adapter supplied with the unit is fitted with a molded plug
for connection to a standard electrical mains system supply socket. If
this plug is not suitable for connection to your mains supply, contact
your reseller for advice. Do not attempt to connect to the mains
supply using an inappropriate mains adapter.
Protect the unit from sudden, transient increases and decreases in
electrical power by fitting an in-line surge suppressor or
uninterruptible power supply.
Products manufactured by 3Com are safe and without risk provided
they are installed, used, and maintained in good working order and in
accordance with their instructions and recommendations.
Should any of the following conditions occur, isolate the electricity
supply and refer to your 3Com reseller.
If the case or cover is not correctly fitted.
If the case is damaged.
If the unit begins to make an odd noise, smell or smoke.
If the unit shows signs of a distinct change in performance.
Never install telephone wires during a thunder storm, or install
telephone connection sockets in wet locations (unless the socket is
specifically designed for wet locations).
Do not touch uninstalled telephone wires or terminals unless the
telephone line has been disconnected at the network interface.
Always exercise caution when installing or modifying telephone lines.
Do not use a telephone that is connected to the unit to report a gas
leak in the vicinity of the leak.

Do not use a telephone that is connected to the unit (other than a
cordless type) during an electrical storm. There may be a remote risk
of electric shock from lightning.
Do not spill food or liquids on the unit. If the unit gets wet, isolate the
electrical supply and contact your 3Com reseller.
Do not push any objects into the openings of the unit. Doing so can
cause fire or electric shock by shorting out internal components.
Ensure nothing rests on the unit's system cables and that the cables
are not located where they can be stepped on and cause damage to
the unit.
Keep the unit away from radiators and heat sources. Allow 25mm (1
inch) around the unit or stack to provide adequate air circulation.
Install the unit in a clean area that is free from dust or extreme
temperatures.
The unit has been designed to be a free standing unit. Do not place
anything else on top of the unit's case.
Allow a clearance gap of at least a 150 mm from the rear panel of the
unit, to allow for cable access.
This unit contains a lithium battery which is attached to a microchip
on the printed circuit board. The defective battery must be disposed of
safely in accordance with the manufacturers instructions.
Cette unité contient une pile au lithium attachée à une puce sur la
carte à circuit imprimé. Se débarrasser de la pile défectueuse en toute
