After making network connections as described in the
preceding sections, you are ready to plug the hub in and turn it
on.
The hub can run on DC power with 5 Volt, 2A(FN-500) or 4A
(FN-800). The external power supply attached is specialized
for FN-500/FN-800 Fast Ethernet hub. The input voltage is
from 90 to 240 volts AC and any frequency from 50 to 60
hertz. Adjustment to the power source is automatic; there is no
switch to set. The output voltage is 5 volt at 2A or 4A. The
center pole of output jack is polarity "+", outside pole's
polarity "-".
Before plugging the hub in, make sure the power cord (1) is
long enough to reach an AC wall outlet of an approved type,
(2) has plugs that match both the hub's power inlet and the
type of wall outlet you will use, and (3) conforms to safety
regulations in your area.
In most parts of the world you must use a three-conductor
power cord with an integral three-prong grounding plug.
If the supplied power cord does not meet all three
requirements given above, contact your computer equipment
dealer and obtain one that does. Do not use an extension cord
or multi-socket adapter; do not attempt to use a cord designed
for any other kind of power inlet or wall outlet; do not use a
cord that fails to meet safety standards in your part of the
world.
