Figure 5-2. Front Control Panel Header Pins (JF1)
Connecting the Control Panel
JF1 contains header pins for various front control panel connectors. See Figure 5-2
for the pin locations of the various front control panel buttons and LED indicators
and refer to section 5-9 for details. Note that even and odd numbered pins are on
opposite sides of each header.
All JF1 wires have been bundled into single keyed ribbon cable to simplify their
connection. The red wire in the ribbon cable plugs into pin 1 of JF1. Connect the
other end of the cable to the Control Panel printed circuit board, located just behind
the system status LEDs in the chassis.
See the Connector Defi nitions section in this chapter for details and pin descrip-
tions of JF1.
