Front Panel LEDs
Power. Indicates that the hub is receiving power and is operational.
Collision 10M/100M. Each unit has two Collision LEDs: 10M indicates a collision
on the 10 Mbps segment, and 100M indicates a collision on the 100 Mbps
segment. A collision occurs when two stations within a collision domain
attempt to transmit data at the same time. The contending adapters resolve
each collision by means of a wait-then-retransmit algorithm. Intermittent
flashing of the Collision LED is normal. Frequency of collisions is an indicator
of heavy traffic on the network.
100M. When lit this LED indicates the port is operating and/or configured
(Ports 1 and 2) at 100 Mbps. When the LED is OFF (not lit), the port is
operating and/or configured at 10 Mbps. Each port has a 100M LED.
Link/Activity/Error. Steady green (Link state) indicates that the port has good
linkage to its associated device. Flashing green (Receive state) indicates that
the port is receiving data from its associated device. Flashing yellow indicates
that an error occurred and that the port is partitioned. Each port has a Link/
Activity/Error LED.
Back Panel LEDs
Connectors, the Port 1 and 2 speed DIP switch and the uplink switch are on
the back panel of the hub.
Speed DIP Switch. This DIP switch manually selects auto-negotiation, 10 Mbps,
or 100 Mbps speed for Port 1 and Port2. Figure 3 shows an close-up of the DIP
switch setting. In the example below, Port 1 is in the Auto position and Port 2
is in the 100M position.
Figure 3 Close-up of DIP Switch Setting
Ethernet Ports. The hub has 8 or 16 ports located on the back panel; all are auto-
negotiating, dual speed 10Base-T/100Base-TX ports.

Uplink Switch. The slide switch located on the right side of the back panel is for
the uplink function. To use Port 8 as an Uplink port, manually set the switch
to the “Uplink” position. This eliminates the need for a crossover cable when
connecting directly to another hub.
Power Connection. For compatibility with electric service in most areas of the
world, the hub two-piece power adaptor automatically adjusts to line power
range 100~220 VAC and 50~60 Hz. Per ordering option, a country specific
power receptacle cord is also supplied with your hub.

To Interlock a Group of LanEdge Products on a Desktop
The interlocking feature of the LanEdge products makes it easy for you to
install the units on a desk or table. You can place the units on top of each other
and interlock them to form a stack. A stack can consist of any combination of
LanEdge hubs. It is recommended that the heaviest unit be placed as the base
(bottom) unit. For example, if you are installing a LanEdge FastPrint Server,
place it as the base unit; otherwise, if you are installing a LanEdge
OmniConnect, place it as the base unit.
1. Select the base unit and place it up-side down on a work surface. Locate
the rubber feet and bumpers from the accessory bag. Remove the paper
cover from the adhesive and press a rubber foot into eachround receptacle
on the bottom of the unit. Remove the paper cover from the adhesive and
press a rubber bumper into each square receptacle on the bottom of the
unit.
2. Place each of the other units up-side down on a work surface. Locate the
rubber feet and bumpers from the accessory bag. Do not install the square
rubber bumpers. Remove the paper cover from the adhesive and press a
round rubber foot into each round receptacle on the bottom of the unit.
Note
The LanEdge products will not interlock properly if the square rubber
bumpers are installed on the interlocking (upper) unit; install these
bumpers only on the base unit.
3. Place the first LanEdge unit on the desktop as the base. If you are
installing a FastPrint Server, place it as the base (bottom) unit; otherwise,
if you are installing a OmniConnect, place it as the base unit.

Connecting Cables
The FastHub8 and FastHub16 have 8 and 16 ports on the back panel,
respectively. If theport isconnected butthe Link/Activity LED is dark(not lit),
refer to Chapter 3, “Troubleshooting” on page 11 for further instructions.
Connect devices to the hub ports using the following guidelines.
Station Connections
Connect each station to the hub with a twisted-pair straight cable (10Base-T
cable, Category 3, 4, or 5). Plug the RJ45 connector into a port on the hub, and
plug the other end of the RJ45 cable into the station’s Ethernet adapter. If
necessary, adjust port speed on Ports 1and2 bysetting the DIP switches before
connecting other devices.
Caution
Be sure to use Category 5 UTP cable when connecting 100 Mbps network
devices. The cable length should not exceed 100 meters (328 feet).
Hub to Hub Connections
To use Port 8 as an uplink to another hub, manually set the uplink switch (on
the back of the hub) to the “Uplink” position. This eliminates the need for a
crossover cable.
Caution
The uplink cable length should not exceed 5 meters (16 feet) in an 100
Mbps configuration.
Your hub is ready for use.

Troubleshooting
No Power
If the Power LED is OFF, check the following to isolate the problem:
❑Make sure the AC/DC adapter is properly connected to the power
outlet and inserted into the power connection on the hub.
❑Determine whether ornot the outlet is functional by plugging another
device into the receptacle.
❑Power the unit OFF and ON again.
If the problem presist, contact Allied Telesyn’s Technical Support. Refer to
Appendix D for technical support telephone and fax numbers in your area.
Link/Activity LED
If the port is connected but the Link/Activity LED is dark (not lit), check the
following to isolate the problem:
❑The hub and the connected device’s power are ON.
❑The port’scable is firmly seated in its connectors at thehub and at the
connected device.
❑The connectedcableisgoodand is thecorrect type.Makesurethat you
use Category 5 UTP cable in connecting 100 Mbps network devices;
the cable length should not exceed 100 meters (328 feet).
❑The connecting device, including any network adapter, is functioning.
❑For Port 8, check that the uplink switch is properly set for the
connected device. When connected to another hub, the uplink position
of this switch eliminates the need for a crossover cable. Note that only
one device should be set to “Uplink”.

Troubleshooting
12
100M LED
If the 100M LED for the port does not indicate the correct speed, check the
following:
❑If the port is auto-negotiating, wait 1-3 seconds after the device cable
is connected, or power is applied, for the negotiation process to
complete.
❑If Port 8 is used as an “Uplink”, check that the cable length used for
an uplink does not exceed 5 meters (16 feet) in an 100 Mbps
configuration.
❑For Ports 1 and 2, check that the speed is correctly set on the DIP
switch. If necessary, adjust port speed onPorts 1 and 2 by manually
setting the DIP switches before connecting other devices.
Connectivity Testing
The following procedure tests each port for a valid connection and correct
operation of the network.
1. Power OFF the unit.
2. Starting with Ports 1 and 2, set the DIP switch (on the back of the unit) to
the appropriate configuration. Refer to “Station Connections” on page 10.
Connect these two ports of a single unit to two nodes or workstations and
apply power to the hub.
3. Make sure the Link/Activity and other LEDs of both hub ports are lit. If
the port is auto-negotiable, wait approximately 1-3 seconds for the process
to complete after power is applied or after the cables are reconnected.
4. After confirming that Port 1 and Port 2 are operational, reconnect one of
the nodes/workstations to another port, then repeat this communications
test with the hub’s remaining ports. Continue to verify the connection on
each port by checking the Link/Activity and other LEDs of both hubs.
Note
When testing Port 8 connection to a workstation, set the uplink
switch to the Normal position.
