Ethernet NIC
If your computer has an Ethernet NIC, you can connect the DSL-2870B to this Ethernet port using an Ethernet cable. You can also use the Ethernet ports on the DSL-2870B
to connect to other computer or Ethernet devices.
DHCP Client status
Your DSL-2870B ADSL router is configured, by default, to be a DHCP server. This means that it can assign an IP address, subnet mask, and a default gateway address to
computers on your LAN. The default range of IP addresses the DSL-2870B will assign are from
192.168.1.2 to 192.168.1.254
. Your computer (or computers) needs to be
configured to obtain an IP address automatically (that is, they need to be configured as DHCP clients.)
Once you have the above information, you are ready to setup and configure your DSL-2870B ADSL router.

Device Installation
The DSL-2870B connects two separate physical interfaces, an ADSL (WAN) and an Ethernet (LAN) interface. Place the router in a location where it can be 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 procedures.
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.
Power on Router
The router must be used with the power adapter included with the device.
1.
Insert the AC Power Adapter cord into the power receptacle located on the rear panel of the router and plug the adapter into a suitable nearby power source.
2.
Press the Power button into the on position. You should see the Power LED indicator light up and remain lit.
3.
If the Ethernet port is connected to a working device, check the Ethernet LED indicators to make sure the connection is valid. The router will attempt to establish the
ADSL connection, if the ADSL line is connected and the router is properly configured this should light up after several seconds. If this is the first time installing the
device, some settings may need to be changed before the router can establish a connection.
Factory Reset Button
The router may be reset to the original factory default settings by using a ballpoint pen or paperclip to gently push down the reset button in the following sequence:
1.
Press and hold the reset button while the device is powered on for 10-15 seconds.
2.
Release the reset button.
Remember that this will wipe out any settings stored in flash memory including user account information and LAN IP settings. The device settings will be restored to the
factory default IP address
192.168.1.1
and the subnet mask is
255.255.255.0.
The default management u
sername is “
admin
” and the default
p
assword is “
admin
”

Network Connections
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 phy
sical link to the service provider’s network
backbone and ultimately to the Internet.
Connect Router to Ethernet
The router may be connected to a single computer or Ethernet device through the 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 10/100/1000Mbps. 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 ports on the
router are 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 PC 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.
Hub or Switch to Router Connection
Connect the router to an uplink port (MDI-II) on an Ethernet hub or switch with a straight-through cable. If you wish to reserve the uplink port on the switch or hub for another
device, connect to any on the other MDI-X ports (1x, 2x, etc.) with a crossed cable.
Computer to Router Connection
You can connect the router directly to an Ethernet adapter card (NIC) installed on a PC using the Ethernet cable provided.
