VX1410A & VX1420A IntelliFrame Mainframe Instruction Manual
B–1
Appendix B: Special Configuration Options
This appendix contains information for configuring your IntelliFrame Mainframe
for specific situations not documented earlier in this manual. These special
configuration options require you to disassemble parts of the mainframe to
access jumpers or circuit boards. Refer to Maintenance for detailed information
on the assembly and disassembly procedures. You may also need to refer to the
exploded views in Replaceable Parts.
The information in this section is intended for use by qualified service personnel.
Read the General Safety Summary and Service Safety Summary at the front of
this manual and the static precautions on page 8–1 before attempting any
procedures in this appendix. Refer to the Operating Basics chapter for informa-
tion on the location of controls, indicators, and connectors used with the
mainframe.
CAUTION. To avoid damage from high currents on the backplane, always power
off the mainframe and disconnect the power cord before performing any of the
configuration procedures for the mainframe described in this appendix.
Remote Power Switch Configuration
You can control the power-on function of the mainframe by the front panel
On/Standby switch and from a remote momentary switch through the connec-
tions of the 25-pin rear panel connector. If you connect a remote switch to
pins 5 and 18 (return side) of the 25-pin connector, the remote switch and the
front panel On/Standby switch control the power-on functions of the mainframe.
You can also disable the front panel switch and control the power-on functions
from the remote switch only. The backplane has two connectors that control the
power-on functions. If the front panel switch is connected to the backplane at
J22, the switch controls the power-on functions. If the switch is connected to
J23, the front panel switch is disabled, however, the light still illuminates when
the mainframe is powered on. To configure the mainframe to disable the front
panel On/Standby switch, perform the following steps:
1. Disconnect the power cord from the mainframe.
2. Remove the cover from the mainframe.
3. Refer to Figure B–1 and locate the two connectors at the top of the back-
plane.
