Checking the Power LED
If the Power LED is off, check the power supply connections. (The modem does not
have an off/on switch.) If the Power LED is on, proceed to
Checking the LAN LED on
page 103.
Checking the LAN LED
If the front panel LAN LED is off:
1. Disconnect and reconnect the Ethernet cable from the modem and from the
computer. Make sure the cable is securely connected to the modem LAN port
and to the computer’s LAN port.
2. If the LAN LED is still off, power cycle the satellite modem:
a. Unplug the power cord from the power source.
b.
If the modem is connected to a DC power source , unplug the DC input cable
from the satellite modem’s power supply.
c. Wait 10 sec.
d. Plug the power cord back into the power source.
e.
If the power source is DC , plug the input cable back into the power supply.
Do not power cycle the satellite modem by unplugging the power cord from the
modem’s rear panel. Doing so could result in static electricity discharge that
could shock you and/or damage the modem.
3. If the LAN LED is still off, check the LAN port LEDs on the back panel.
•
If the Orange LED is on and the front panel LAN LED is not, contact Installer
Support for assistance.
•
If both the Orange LED and the front panel LAN LED are off, check all network
equipment that connects the computer with the modem, including the
computer’s Ethernet card, Ethernet cable(s) and any switch or hub. Replace one
or more of the items to try to isolate the problem.
4. If the front panel LAN LED is still off, check the Windows Device Manager to see
if the computer’s NIC or network adapter is installed correctly.
a. In Windows XP, for example, click Start > Settings > Control Panel > System >
Hardware > Device Manager .
A screen appears listing all the devices installed on the computer.
b. Look for Network adapters.
If the NIC is not properly installed, a red X appears next to its listing.
c. If a red X is present, troubleshoot the NIC installation using the manufacturer’s
instructions and Windows documentation.
5. If the LAN LED is still off, follow this step only if the satellite modem is connected
to a hub, router, or other network device (that is, not connected directly to the
computer).
Connect the computer directly to the satellite modem (to bypass the
network device) as follows:
a. Disconnect the Ethernet cable from the device.
