FCC COMPLIANCE STATEMENT
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.

11 Introduction
Congratulations on your purchase of Edimax’s 8-port dual-speed hubs. Migrating
from traditional 10Mbps Ethernet to 100Mbps Fast Ethernet is now simple and
affordable with Edimax’s dual-speed hubs. Edimax’s high performance 8-port
desktop 10/100Mbps dual-speed hubs (ED-1508/ED-1508X/ED-1508S/ED-1508SX)
are equipped with 8 RJ45 dual-speed ports and one selectable uplink port using slide
switch.
Typically a dual-speed hub has two independent internal network segments: 10Mbps
segment and 100Mbps segment. Depending on the speed of attached network
devices, each individual port of a dual-speed hub provides Auto-Negotiation
capability which automatically senses and selects optimum speed at 10Mbps or
100Mbps. A 10Mbps network device attached to the dual-speed hub will be able to
communicate with other network devices attached to the hub running at 10Mbps. On
the other hand, a 100Mbps network device attached to the dual-speed hub will be
able to communicate with other devices attached to the hub running at 100Mbps.
Therefore, dual-speed hub can be 10Base-T hub when all the connecting nodes are
running at 10Mbps as illustrated in Figure 1-1, or can be 100Base-TX hub when all
the connecting nodes are running at 100Mbps as illustrated in Figure 1-2. ED-1508
series dual-speed hubs are the ideal hubs for both 10Base-T and 100Base-TX
networks.

devices to ED-1508 and ED-1508S dual-speed hubs, the 10Mbps
devices will not communicate with 100Mbps devices.

Dual-Speed hub with internal switching function (Model ED-1508X & ED-1508SX)
automatically switches data traffic between devices running at different speed, which
allows communications between ports running at 10Mbps and ports running at
100Mbps. Dual-Speed hub with internal switching function can save money by
eliminate the need to purchase expensive Switches for users with mixed speed
network environment. The connection of the dual-speed hub with internal switching
function is illustrated as below :

The “S” models (ED-1508S & ED-1508SX) provide the stackable feature. They can
stack together up to four hubs to form a logically “Big” dual-speed Hub.
ED-1508/ED-1508X/ED-1508S/ED-1508SX Dual-Speed hubs can be set up as
stand-alone units or they can be wall-mounted.
ED-1508 series dual-speed hubs’ compact and slim design allows direct placing on
the desktop or a small closet. They can also be conveniently mounted on the wall or
the side of a desk to accommodate cabling consideration.

55 Installation
1. Operating Environment
ED-1508/ED-1508X/ED-1508S/ED-1508SX 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
Connect one end of the network cable to any of the eight RJ45 ports on the front
panel, and connect the other end of the network cable to the RJ45 port of the network
device. The network cables must comply with EIA/TIA 568 specifications and
Category 5 standard for 100Mbps data rate or minimum Category 3 for 10Mbps data
rate. Maximum length between the hub and any network devices is 100 meters
(300ft). Once the network cable is connected on both ends and the attached network
devices are powered on, the green Link Status LED should be lit. If the connected
network devices are running at 100Mbps, the green Speed LED (100M) should also
be lit.

3. Uplink to Another Hub
Use the Uplink port (8th port) to connect to another hub as illustrated below.
Connecting cable must comply with EIA/TIA 568 specifications and Category 5
(100Mbps) standards to connect the hubs. The Uplink port of the Dual-Speed hub
supports Auto-Sensing function which will automatically sense the speed of the
connected hub and operates at either 100Mbps or 10Mbps speed. If the connected
hub is another Dual-Speed hub or 100Base-TX hub, the transmission speed between
the two hubs will be set at 100Mbps and the green Speed (100M) LED should be lit.
The maximum length of the cable should not exceed 5 meters (15ft) when
connecting two hubs running at 100Mbps and 100 meters (300ft) when connecting
two hubs running at 10Mbps.

4. Stacking Hubs Together
ED-1508S and ED-1508SX provide two stacking ports. Users may connect two hubs
using the supplied stacking cable. Connect one end of the stacking cable to the “IN”
stacking connector of the hub and the other end of the stacking cable to another hub
“OUT” stacking connector. You may stack up to 4 hubs. The hubs cascaded
together through stacking ports are in one collision domain and therefore considered
as one logical hub. Only one ED-1508SX is required to provide internal switching
function to all the ports in the stacked hubs (ED-1516S).

* Caution : When you have two or more ED-1508SX stacked together, only one ED1508SX hub’s internal switch is active, the others are inactive. Such
design will eliminate a “Loop” in the network that might cause the whole
network to malfunction.
5. Connecting the power
Dual Speed Hub
Connect the power cord to the power
socket on the external switching power
adapter. Connect the DC power jack to
the DC power socket on the rear panel
of the switch. Connect the power cord
to the power outlet. The green Power
LED on the front panel should be lit.

66 Trouble-shooting
1. Power LED is not lit
l Check if the power cord is properly connected to the external switching power
adapter and the power outlet. Make sure the DC power jack is firmly plugged
into the power socket of the hub.
2. Link Status LED is not lit
l Check the power switch of the network devices attached to the hub; make sure
they are turned ON.
l Check the network cables; make sure they are properly connected to the hub and
the network devices.
l Check the network cables; make sure the cables comply with EIA/TIA 568
specification. Use straight-through Category 5 cables for 100Mbps connection and
Category 3 or higher cables for 10Mbps connection.
l Check the slide switch and make sure it’s in normal position when you use the last
port on the hub to connect to workstations or file servers.
3. 8th port’s Link Status LED is not lit when it is uplinked to another hub
l Make sure the uplink slide switch is shifted to "uplink" position.
l Check the network cable; make sure it is properly connected to both hubs. The
slide switch next to the last port should be shifted to "uplink" position. One end of
the cable should be connected to last port while the other end of the cable should
connected to a regular port. Do not connect the cable to both uplink ports.
l Check the network cable; make sure the cable complies with EIA/TIA 568
specification. Use CAT5 cables for 100Mbps connection and minimum CAT3
cables for 10Mbps connection.
l Check the network cable; make sure the maximum length does not exceed 5
meters (15ft) when this port is used for 100Mbps connection.
4. Collision LED flashes constantly
l Remove all the network cables; connect the cables back one by one to isolate the
source of the collision.
l Check the network cable, inferior cable quality will result in excessive collision
and error packets.
[!] Contact your dealer if problem persist.
