5) NLX Power Supply Connector (20-pin block)
This connector connects to an NLX power supply. The plug from the power sup-
ply will only insert in one orientation because of the different size holes. Find the
proper orientation and push down firmly making sure that the pins are aligned.
IMPORTANT: Make sure that the NLX power supply can deliver at least 720mA
on the 5volt standby lead (+5VSB). You may experience difficulty in powering
ON your system without this specification.
