Installation
COM Tx / COM Rx
The COM Tx LED shines when the built-in modem is transmitting
data out the RJ-11 phone jack to the Internet. The COM Rx LED
shines when data is being received by the built-in modem via the RJ-
11 phone jack. These LEDs are off when no data is being transmit-
ted or received.
Normal LED Flash Pattern
When the device is powered up, the Pw/Tx LED comes on. The other
LEDs come on immediately afterward, and all four LEDs remain lit
for several seconds. Then the COM Tx and COM Rx LEDs go dark,
flash three times, and go dark again. The Link/Rx LED then flickers
very briefly and goes dark. After a few seconds, the Link/Rx LED
starts showing link status as described above, and the COM Tx and
COM Rx LEDs flash three times in alternation. The device is then
fully ready for operation.
If a problem is detected during this time, the LED flashes will dis-
play an error pattern (see Appendix A: Troubleshooting for more
information on POST error indications). If no errors are detected,
the Internet server will begin operating normally.
Connecting to the Local Network
This section describes how to connect the DP-601M internet server to
your Ethernet/Fast Ethernet network.
Cables
•
The EIA/TIA 568 Wiring Standard imposes a 100 meter
limit on horizontal runs of twisted-pair cables; in this
case, from the internet server to any other device.
