20)ATX Power Supply Connector (20-pin block ATXPWR)

This connector connects to an ATX power supply. The plug from the power sup- ply will only insert in one orientation because of the different hole sizes. Find the proper orientation and push down firmly making sure that the pins are aligned.

IMPORTANT: Make sure that your ATX power supply can supply at least 10mA on the +5-volt standby lead (+5VSB). You may experience difficulty in powering ON your system if your power supply cannot support the load. For Wake- On-LAN support, your ATX power supply must supply at least 720mA +5VSB.

21)IDE Activity LED (2-pin IDELED)

This connector supplies power to the cabinet’s IDE activity LED. Read and write activity by devices connected to the Primary/Secondary IDE and Primary/ Secondary ATA100 connectors will cause the LED to light up.

TIP: If the case-mounted LED does not light, try reversing the 2-pin plug.
