You should place the Router in a location that:

■

is conveniently located for connection to external ADSL or Cable

modem.

■

is centrally located to the wireless computers that will connect to the

Router. A suitable location might be on top of a high shelf or similar

furniture to optimize wireless connections to computers in both

horizontal and vertical directions, allowing wider coverage.

■

allows convenient connection to the computers that will be connected

to the four LAN ports on the rear panel, if desired.

■

allows easy viewing of the LED indicator lights, and access to the rear

panel connectors, if necessary.

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 flat top units. Only

stick the feet to the marked areas at each corner of the underside of your

Router.

Please be careful when you put 3COM Router on top of another unit, if

the unit underneath is hot, this may impact the reliability of 3Com Router.

Wall Mounting

There are two slots on the underside of the Router that can be used for

wall mounting. The Router must be mounted with the LEDs facing

upwards.

When wall mounting the unit, ensure it is within reach of the power

outlet. When wall mounting the unit, ensure that the rubber feet are not

fixed.
