Front Panel Display

Place the Router in a location that permits an easy view of the LED indicators on the front panel.

The LED indicators on the front panel include the

Power

,

Status

,

ADSL Link/Act

and

LAN (1-4)

Link/Act

indicators. The ADSL and Ethernet indicators monitor link status and activity (Link/Act).

Steady green light

indicates the unit is

powered on. When the

device is powered off

this remains dark.

Lights steady green

during power on self-

test (POST). Once the

connection status has

been settled, the light

will blink green. If the

indicator lights steady

green after the POST,

the system has failed

and the device should

be rebooted.

Steady green light

indicates a valid ADSL

connection. This will

light after the ADSL

negotiation process has

been settled. A blinking

green light indicates

activity on the WAN

(ADSL) interface.

A solid green light

indicates a valid link on

startup. These lights

blink when there is

activity currently

passing through the

Ethernet port.

Hardware Installation

The DSL-504T maintains five separate interfaces, four switched Ethernet ports and one ADSL

interface. Place the Router in a location where it can be easily connected to the various devices as

well as to a power source. The Router should not be located where it will be exposed to moisture or

excessive heat. Make sure the cables and power cord are placed safely out of the way so they do

not create a tripping hazard. As with any electrical appliance, observe common sense safety

precautions.

The Router can be placed on a shelf or desktop, ideally you should be able to see the LED

indicators on the front if you need to view them for troubleshooting. To conserve desktop space,

the Router is shipped with plastic feet that can be snapped into place to support it. The Front and

Rear panel views presented above show the device mounted using the plastic feet.

Power on Router

CAUTION:

The Router must be used with the power adapter included with the device.

To power on the Router:

1.

Connect

the power adapter shipped with the Router to the power recepticle on the

back panel

of the device.

2. Plug the power adapter to an suitable electrical wall outlet or power strip.

3. Toggle the power switch on the back panel to power on the Router. The

Power LED

on the front of the Router will light green indicating it is powered on

.

Factory Reset Button

The Router may be reset to the original factory default settings by depressing the reset button for

a few seconds while the device is powered on. Use a ballpoint pen or paperclip to gently push down

the reset button. Hold the reset button down until the Status light goes dark. Remember that this

will wipe out any settings stored in flash memory including user account information and LAN IP

settings. The factory default IP address of the Router is 10.1.1.1 and the subnet mask is 255.0.0.0,

the default management Username is

admin

and the default Password is

admin

Network Connections

Network connections are provided through the ADSL port and the four Ethernet ports on the back

of the Router. See the Rear Panel diagram above and the illustrations below for examples.

Connect ADSL Line

Use the ADSL cable included with the Router to connect it to a telephone wall socket or receptacle.

Plug one end of the cable into the ADSL port (RJ-11 receptacle) on the rear panel of the Router and

insert the other end into the RJ-11 wall socket. If you are using a low pass filter device, follow the

instructions included with the device or given to you by your service provider. The ADSL connection

represents the WAN interface, the connection to the Internet. It is the physical link to the service

provider

’

s network backbone and ultimately to the Internet.

Connect Router to Ethernet

The Router may be connected to computers or Ethernet devices through the 10BASE-TX Ethernet

ports on the rear panel. Any connection to an Ethernet concentrating device such as a switch or

hub must operate at a speed of 10/100 Mbps only. When connecting the Router to any Ethernet

device that is capable of operating at speeds higher than 10Mbps, be sure that the device has

auto-negotiation (NWay) enabled for the connecting port.

Use standard twisted-pair cable with RJ-45 connectors. The RJ-45 port on the Router is a crossed

port (MDI-X). Follow standard Ethernet guidelines when deciding what type of cable to use to make

this connection. When connecting the Router directly to a computer or server use a normal

straight-through cable. You should use a crossed cable when connecting the Router to a normal

(MDI-X) port on a switch or hub. Use a normal straight-through cable when connecting it to an

uplink (MDI-II) port on a hub or switch.

The rules governing Ethernet cable lengths apply to the LAN to Router connection. Be sure that the

cable connecting the LAN to the Router does not exceed 100 meters.
