This equipment generates and uses radio frequency energy and if not installed
and used properly, that is, in strict accordance with the instructions provided with
the equipment, may cause interference to radio and TV reception. The
equipment has been tested and found to comply with the limits for a Class A
computing device in accordance with the specifications in Subpart B of Part 15
of FCC rules, which are designed to provide reasonable protection against such
interference in a commercial environment. However, there is no guarantee that
interference will not occur in a particular installation.
If you suspect this equipment is causing interference, turn your hub on and off
while your radio or TV is showing interference to determine the source of the
interference.
You can try to correct the interference by one or more of the following measures:
1. Reorient the receiving radio or TV antenna where this may be done safely.
2. To the extent possible, relocate the radio, TV or the other receiver away
from the equipment.
3. Plug the computer which has the equipment installed into a different power
outlet so that equipment and the receiver are on different branch circuits.
If necessary, you should consult the place of purchase or an experienced radio/
television technician for additional suggestion.
CAUTION : The phone jack cannot be connected to telephone system.

1Introduction
Congratulations on your purchase of Edimax’s 9-port desktop Ethernet 10Base-T
hub - ER-5390S. This hub is specifically designed to provide simple, reliable and
economical solution in small Ethernet 10Base-T networks.
With eight RJ-45 and one BNC ports, ER-5390S supports up to eight workstations
running at 10Mbps on unshielded twisted-pair cables and at the same time, connect
to other Ethernet devices through the coaxial cable as illustrated in Figure 1-1.
Several ER-5390S can be connected together using the BNC ports to support a larger
network.
An uplink port located right next to the 8th RJ-45 port allows easy connection to
other hubs or switches using regular straight-through cables as illustrated in Figure
1-2.
ER-5390S’s slim and compact design allows direct placing on the desktop or
conveniently mounted on the wall or the side of a desk to accommodate cabling
consideration.

5Installation
1. Operating Environment
ER-5390S must be installed and operated within the limits of specified operating
temperature and humidity (see previous section under Specifications). Do not place
objects on top of the unit. Do not obstruct any vents at the sides of the unit. Do not
position the hub near any heating source such as heater, radiator, or direct exposure
to sun. Prevent entering of water and moisture into the unit. If necessary, use
dehumidifier to reduce humidity.
2. Connecting to network devices with UTP cable
Connect one end of the network cable to any of the RJ-45 ports on the rear panel,
and connect the other end of the network cable to the RJ-45 port of the network
device. The network cables must comply with EIA/TIA 568 specifications and
minimum Category 3 standard for 10Mbps data transmission. Maximum length
between the hub and workstation is 100 meters (300ft). Once the network cable is
connected on both ends and the attached network devices are powered on, the green
LNK/Rx (Link Status) LED should be lit.
3. Uplink to Another Hub with UTP cable
Use uplink port to connect to another hub as illustrated in Figure 1-2. Connect one
end of the network cable to the uplink port and connect the other end to any of the
regular port in the other hub (except the uplink port). Connecting cable must comply
with EIA/TIA 568 specifications and Category 3 standards to connect the hubs.
Once the network cable is connected and both hubs are powered on, the green
LNK/Rx (Link Status) LED should be lit. Do not use the uplink port and 8th port at
the same time.
NOTE : The maximum length of the uplink cable shall not exceed 100 meters (300
feet).

4. Connecting to network devices with coaxial cables
Attach the T-connector to the BNC port on the rear panel and connect the coaxial
cables to the both open ends of the T-connector as illustrated in Figure 5-2. If the
ER-5390S is at either end of the coaxial segment, make sure terminate the open end
of T-connector with a 50-ohm terminator.
Note : Do not connect coaxial cable directly to the BNC port without using T-
connector.
5. Connecting the power
Connect the DC power jack to the DC
power socket on the rear panel of the
hub. Connect the power adapter to the
power outlet. The green Power LED
on the front panel should be lit.

6Trouble-shooting
1. Power LED is not lit
lCheck if the external power adapter is plugged into the power outlet. Make sure
the DC power jack is firmly plugged into the power socket of the hub.
2. LNK/Rx LED is not lit after connecting to an active workstation
lCheck the power switch of the network devices attached to the hub; make sure
they are turned ON.
lCheck the network cable; make sure it is properly connected to the hub and the
network device.
lCheck the network cable; make sure the cable complies with EIA/TIA 568
specification. Use straight-through minimum Category 3 grade cables.
lDo not use uplink port to connect to a workstation.
lThe BNC port’s Rx LED normally is not lit unless there’s data transmission on the
coaxial cable.
3. Uplink (8th) port’s LNK/Rx LED is not lit after uplink to another hub
lCheck the network cable; make sure it is properly connected to both hubs. One
end of the cable should be connected to uplink port while the other end of the
cable should be connected to a regular port. Do not connect the cable to another
uplink port.
lCheck the network cable; make sure the cable complies with EIA/TIA 568
specification.
lCheck the length of the network cable does not exceed 100 meters (300 feet).
lMake sure both hubs are powered ON.
4. Partition LED is lit
lIt’s normal that the BNC port’s partition LED is lit when there’s no coaxial cable
is attached. Once the cable is attached, the BNC partition LED shall be off within
seconds.
lCheck the connected devices. The hub will automatically partition a defective
Ethernet device which causing excessive errors.
8

5. Collision LED is constantly flashing
lRemove all the network cables; connect the cables back one by one to isolate the
source of the collision.
lCheck the network cable, inferior cable quality will result in excessive collision
and error packets.
