Verify that the PWR LED is lit. Verify that the switches on the front of the unit
are in the appropriate positions for the DS3 line. Plug in the local Ethernet
connection and verify the physical link by the LNK LED on the front of the
unit. The unit will not present Ethernet Link until the DS3 line is operational.
For most applications, use a straight-through Ethernet cable when
plugging the Providers into a PC. Use a cross-over cable when plugging
into a hub or a switch. Verify the pinout of the Ethernet device into
which you are connecting the Provider to determine which type of cable
is required. The pinout of the Provider's Ethernet port is shown in Table
2-1.
