6-2 Front Control Panel
The front control panel must be connected to the JF1 connector on the serverboard
to provide you with system status and alarm indications. A ribbon cable has bundled
these wires together to simplify this connection. Connect the cable from JF1 on the
serverboard (making sure the red wire plugs into pin 1) to the appropriate comnnec-
tor on the front control panel PCB (printed circuit board). Pull all excess cabling over
to the control panel side of the chassis. The LEDs on the control panel inform you
of system status - see Figure 6-2 for details. See Chapter 5 for details on JF1.
