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.
