VX1410A & VX1420A IntelliFrame Mainframe Instruction Manual
The On/Standby switch on the top-left corner of the front panel applies DC
voltages to the mainframe. The switch is a momentary contact switch. The
switch is lighted when DC voltages are applied to the mainframe. You can also
remotely power on or power down the mainframe.
You can configure your mainframe to bypass the On/Standby switch (refer to
Remote Power Switch Configuration in Appendix B of this manual for informa-

while power is applied; however, the switch itself no longer controls the
mainframe. The switch can also be configured to activate SysReset, Refer to
Front Panel SYSReset Cable Connector Configuration in Appendix B.

alphanumeric display indicating the status of the system . The NEXT and PREV
push buttons, located to the right of the display, allow you to scroll through the
display selections. See Figure 2–2.
