If you experience problems during installation, unplug all connections, except the
LAN connection, and then restart the Instant Internet unit.
You can mount your Instant Internet unit in an equipment rack or place it on a flat
surface. If you choose not to mount the Instant Internet unit in a rack, be sure to
install the unit’s rubber feet. If the feet are not installed, stick the adhesive side of
the feet on the spaces provided on the bottom of the unit. You need to use either
the mounting brackets or the feet.
To install your Instant Internet hardware:
1 Do one of the following:
• If you want to mount your Instant Internet unit in a rack, you must do so
before you connect it to your LAN. Follow the procedure
“Mounting your
Instant Internet unit in a rack” on page 46 and then return to this
procedure and continue with step 2 .
• If you do not want to mount your Instant Internet unit in a rack, place the
unit on any appropriately level surface that can safely support the weight
of the unit and attached cables. Make sure that there is adequate space
around the unit for ventilation and access to cable connectors. Allow at
least 2 inches (5.1cm) on each side for proper ventilation and 5 inches
(12.7cm) at the back for power cord clearance and ventilation. Continue
with step
2 .
2 With the tip of a pen, slide the power voltage selector switch to the power
voltage setting that matches your power voltage. For more information, see
“Setting the voltage selector switch” on page 42 .
3
Attach one end of the communications cable to the appropriate connector on
the rear panel of the Instant Internet unit.
• If you are using an analog modem, ISDN, 1-Meg modem, V.35, X.21, T1,
or E1 connection, use slot A for this connection.
• If you are using an external Ethernet device, use the Ethernet connector in
the option slot (Eth3) to connect to the external modem. Be sure to use the
proper cable (straight-through or crossover) for this connection.
Note:
Do not apply power to the Instant Internet unit until you have
completed the installation steps.
