User’s Manual

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 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.

* CAUTION: If you connect both 10Mbps network devices and 100Mbps network

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.
