NSTALLATION
When positioning your Router, ensure:
■
It is out of direct sunlight and away from sources of heat.
■
Cabling is away from power lines, fluorescent lighting fixtures, and
sources of electrical noise such as radios, transmitters and broadband
amplifiers.
■
Water or moisture cannot enter the case of the unit.
■
Air flow around the unit and through the vents in the side of the case
is not restricted. 3Com recommends you provide a minimum of
25 mm (1 in.) clearance.
Using the Rubber
Feet
Use the four self-adhesive rubber feet to prevent your Router from
moving around on your desk or when stacking with other flat top
OfficeConnect units. Only stick the feet to the marked areas at each
corner of the underside of your Router.
Stacking the Router
If you are stacking your Router with other OfficeConnect units, install the
Router at the top of the stack. Refer to the documentation supplied with
your other OfficeConnect unit for details on using the stacking clip.
A stacking clip is not supplied with the Router. Use the stacking clip
supplied with another stackable OfficeConnect unit.
Wall Mounting
There are two slots on the underside of the Router that can be used for
wall mounting.
When wall mounting the unit, ensure that it is within reach of the power
outlet.
You will need two suitable screws to wall mount the unit. To do this:
1
Ensure that the wall you use is smooth, flat, dry and sturdy and make two
screw holes which are 150 mm (5.9 in.) apart.
2
Fix the screws into the wall, leaving their heads 3 mm (0.12 in.) clear of
the wall surface.
3
Remove any connections to the unit and locate it over the screw heads.
When in line, gently push the unit on to the wall and move it downwards
to secure.

When making connections, be careful not to push the unit up and off the
wall.
CAUTION:
Only wall mount single units, do not wall mount stacked
units.
Before you Install
your Router
Before you install and configure your Router, you need the following
additional information. If you do not have this information, contact your
Internet Service Provider (ISP). Space is provided below for you to record
this information.
If you have a DSL connection and your ISP allocates IP information
dynamically over PPPoE, you need a User Name and Password:
You only need a PPPoE Service Name if your ISP requires one. Do not
enter anything if your ISP does not require this information.
If you have a DSL connection and your ISP allocates IP information
dynamically over PPTP, you need a User Name, Password and PPTP Server

1
Plug the power adapter into the power adapter socket located on the
back panel of the Router.
2
Plug the power adapter into a standard electrical wall socket.

Connecting the Router
To use your Router to connect to the Internet through an external cable
or DSL modem:
1
Insert one end of the supplied Ethernet (RJ-45 Category 5) cable into the
Cable/DSL port on the rear panel of the Router.
2
Insert the other end of the cable into the RJ-45 port on your cable or DSL
modem. Check that the Cable/DSL status LED lights on the Router.
3
Connect the cable or DSL modem to the Internet.
4
Connect your computer to one of the four LAN ports on the Router using
a Category 5 twisted pair cable. Check that the corresponding LAN status
LED on the Router lights.
You have now completed the hardware installation of your Router. Next
you need to set up your computers so that they can make use of the
Router to communicate with the Internet.
3Com recommends that you perform the initial Router configuration
from a computer that is directly connected to one of the LAN ports.
If you configure the Router from a wireless computer, note that you may
lose contact with the Router if you change the wireless configuration.
