Connecting the Control Panel

JF1 contains header pins for various front control panel connectors. See Figure 5-1 for the pin

locations of the various front control panel buttons and LED indicators.

All JF1 wires have been bundled into a single cable to simplify this connection. Make sure the red

wire plugs into pin 1 as marked on the board. The other end connects to the Control Panel PCB

board, located just behind the system status LEDs on the chassis.
