14 Troubleshooting
This chapter suggests solutions for resolving some of the problems you
might encounter when using your HM210dp/di, and provides instructions for
using several IP utilities to diagnose problems.
14.1 LEDs
Indication/Symptom Troubleshooting Suggestion
The PWR LED does not
illuminate after the product
is turned on.
Verify that you are using the power cable provided
with the device and that it is securely connected to
the HM210dp/di and a wall socket/power strip.
The WAN LED does not
illuminate after the ADSL
cable is attached.
Verify that a standard telephone cable (called an RJ-
11 cable) like the one provided is securely
connected to the ADSL port and your wall pone jack.
Allow about 30 seconds for the device to negotiate
with your ISP.
The LAN LED does not
illuminate after Ethernet
cable is attached.
Verify that the Ethernet cable is securely connected
to your LAN hub or PC and to the HM210dp/di.
Make sure the PC and/or hub is turned on. Verify
that you are using a straight-through type Ethernet
cable to the uplink port on a hub or a cross-over
type cable to a stand-alone PC.
Verify that your cable is sufficient for your network
requirements. A 100 Mbit/sec network (10BaseTx)
should use cables labeled CAT 5. A 10 Mbit/sec
network may tolerate lower quality cables.
The DIAG LED stays
illuminated after turning the
device on.
The DIAG LED should turn off after about 10-15
seconds. If it does not, turn off the HM210dp/di, wait
for 10 seconds, and then turn it back on.
