Connecting the Hub to AC Power
After making network connections as described in the
preceding sections, you are ready to plug the hub in and turn
it on.
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.
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.
Page 6
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.
Power Failure
To prevent costly equipment damage and downtime, please consider
installing a surge suppression device or a UPS (un-interrupted power
supply).
Troubleshooting
Check LED Indicators
LED indicators will act follow section “LED Indicators”, please
check the status all the time to have a quick diagnostic of the
network status.
Partitioning
When a problem occurs on a segment connected to the
repeater, the segment is automatically partitioned to isolate
the problem from the rest of the network. The PAR LED
indicator of the port should light up and remain this way
until the problem is corrected.
♦ Check the cable connection in this segment carefully.
Make sure all the devices are well-connected.
♦ Segment termination. Make sure the segment are
terminated by a 50-ohm terminator.
After the problem corrected, ER-700 will automatically reconnect the partitioned segments to the networks.
