Introduction
This manual describes how to install and use the OnQ 8 Port
Ethernet Switch. It features eight (8) lO/lOOMbps Auto-
Negotiation Switch ports and provides flexibility in your networking
environment. The OnQ switch can be used to connect PC’s,
Servers, Hubs, Bridges and other Switches and Routers. It can
also act as a bridge between 1OMbps and 1OOMbps network
segments.
[Figure
Thanks to the switching technology, it supports 1OMbps and
1OOMbps dedicated bandwidths in each port. The device is built
with plug & play, auto-negotiation on all ports, as well as, half and
full-duplex operations, store-and-forward transmission scheme,
IEEE 802.3x flow control and back pressure operation for,easy
installation and smooth transition from legacy 10Mbps to 1OOMbps
Switched-Network. It also contains one (1) MDI port (uplink) to
facilitate your network expansion.
To ensure maximum safety and good function, please read
carefully and follow all directions in this manual to obtain a
successful installation and operation. It is recommended that you
have a basic understanding of Local Area Networking (LAN)
concepts such as bridging, IEEE 802.3, lOBASE-T Ethernet and
IEEE 802.3~ lOOBASE-TX Fast Ethernet.

Uplink Multiple Port
You can use the uplink port of each 8 Port Switching Hub to
cascade to a hub or a switch for connecting many different work-
groups. The Up-Link port is the same port as port 1, but the pin
assignments have been designed to contain crossover’s This
allows you connect this port to a hub or switch hub without a
crossover cable. The maximum distance between each hub to the
switch is 100 meter (refer to Figure 3 below).

Pre-Installation Requirements
Before you connect the Ethernet Switch to the network, make sure
that you have the proper operating environment. To provide the
proper operating condition, make sure the of the following
installation requirements:
Power Requirement: 120VAC @I60Hz
Cable Requirement: CAT5 UTP cable wiring for IOMbps
connection; CAT5 or CAT5E UTP cable wiring for IOOMbps
Installation - Ethernet Hub in OnQ Enclosure
The OnQ 8 Port lo/100 Switch is designed to mount in any OnQ
Service Center.

Align tabs on module with slots
on the rear of the enclosure.
Refer to Figure 4.
Insert tabs by angling module
away from the back of the
enclosure.
Rotate the module and insert
fasteners on module into
corresponding holes on the rear
of the enclosure. (Plunger must
be in pulled position for fastener
to engage hole.)

Connecting Power
1. Plug the AC power adapter, supplied with the Ethernet
Switch, into a near by power outlet.
2. Route the power supply wire neatly and securely to the
Ethernet Switch location.
3. Plug the power connector into the power jack on the rear of
the switch.
Connecting to Outlets
1. Plug a straight through OnQ Category 5 jumper, such as
part number 363201-Xx, to the twisted pair jacks on the
rear panel of the hub.
2. Connect the other end to the desired outlet jack on an OnQ
Network Interface Module, such as part number 363486-01.
Repeat connecting up to eight (8) outlets to the network.
NOTE: Do not use the uplink jack and Port-l at the same
time.
Cascading to another Switch or Hub
You can cascade the OnQ Ethernet Switch to another Ethernet
Switch or Hub. (When attaching the Switch to a Router or other
device, verify the port type implemented before connecting any
cabling.) Refer to Figure 5 on next page.
1. Prepare straight-through Category twisted-pair cable with
RJ-45 plugs. Make sure the cable does not exceed 100
meters (328 feet).
2. Connect one end of the cable to the switch’s uplink port.
When using the uplink port, be sure not to use Port 1.

3.
Connect the other end of the cable to an MDI-X RJ-45 port
on the other device (not an uplink port.)
Alternatively, you can connect from any MDI-X port
on the Switch to an uplink port on the other device.
You may also attach to MDI-X ports at both ends if
you use crossover cabling.
Verify System Operation
Check each connection by viewing the port status indicators
shown in the table on page 2. The Switch monitors the link status
for each port. If the Link indicator fails to light when you connect a
device, follow the trouble-shooting advice detailed on page 8.

Troubleshooting
Diagnosing LED Indicators
The operation of the OnQ Ethernet Switch can be easily
monitored through panel indicators to assist the network manager
in identifying problems. This section describes common problems
you may encounter and possible solutions.
Symptom:
Cause:
Solution:
Symptom:
Cause:
Solution:
Link indicator does not light up after making a
connection.
Network interface (i.e. a network adapter card on the
attached device), network cable or switch port is
defective.
Verify that the switch and attached device are
powered. Be sure the cable is correctly plugged into
both the switch and corresponding device. Verify
that the proper cable type is used and its length
does not exceed specified limits. Each twisted-pair
cable should not exceed 100m (328ft). Check the
adapter on the attached device and cable
connections for possible defects. Replace the
defective adapter or cable if necessary.
Power indicator does not light up (green) after power
adapter is attached.
Defective power outlet, power cord or power adapter.
Check the power outlet by plugging in another
device that is functioning properly. Check the power
cord with another device. If these measures fail to
resolve the problem, have the units power adapter
replaced by a qualified distributor.
