DI-304
DI-304M
The DI-304 has a power jack, an uplink port, four RJ-45 ports, an ISDN port on the rear panel, and a factory reset button. The DI-304M is identical other than the addition of two RJ-11 phone ports. Please note that only the D-Link supplied power adapter should be connected to the power jack.
♦POWER — This socket is an 18 volt, 750mA power input jack. If the power adapter included with the router has been lost or misplaced, please ensure that the replacement adapter meets both the voltage and amperage requirements.
♦ETHERNET – The Ethernet ports function as a normal, dual speed NWay Ethernet switch.
♦Uplink – This port is used to connect the router to another switch or hub using a straight-through twisted-pair cable. When the Uplink port is used, Port 1x is unavailable.
♦Ports 1x to 4x – These four ports can be used to connect end-stations to the router using straight-through cables.
♦ISDN – This socket is used to connect the ISDN line to either an NT-1 or directly to the ISDN wall jack, depending on the type of service delivered by your phone company.
♦PHONE 1 and 2 (DI-304M only) – These normal telephone jacks can be used to connect telephones or fax machines to the router for use over the ISDN lines. Plug telephone devices into these jacks as you normally would into a telephone wall socket.
