Revision 1.4
My AlphaShield™ does not power up. Why?
Ensure that you are using the provided wall mount power adapter
shipped with the AlphaShield™ and not some other power adapter.
(9 volt D.C. 300 mA center positive.)
Make sure that there is 110 volts AC or 220 volts AC being provided
on the wall outlet. In North America 110 VAC.
If all the above is correct then the provided adapter could be faulty.
The Inbound Data link status LED does not come on when I connect
my AlphaShield™ to my Cable or xDSL modem. Why?
Make sure that power is being provided to your cable or xDSL
modem and that it is switched on.
Make sure that the network RJ-45 cable is a straight through connec-
tion and not another variation such as a rollover or crossover cable.
Make sure that the AlphaShield™ modem port is not being connected
to the computer network port.
Even though the cable is the correct type, it could be faulty. Replace
the cable with a new straight through RJ-45 network cable.
The Outbound Data link status LED does not come on when I connect
my AlphaShield™ to my Computer. Why?
Make sure that the power is being provided to your computer and that
the computer is switched on.
Make sure that the network RJ-45 cable is a straight through connec-
tion and not another variation such as a rollover or crossover cable.
Make sure that your Network Interface Card within your computer is
not a fixed Fast Ethernet 100 Mbps card that cannot switch or auto
negotiate to 10 Mbps.
