The PXIe-1092 chassis supports operation in two inhibit modes. Default mode is used when normal power inhibit button functionality is desired. In Default mode, when a system controller is installed in slot 1 of the chassis, the user can press the power inhibit button to power on the chassis.

Note In Default mode, you can also power on the chassis without a system controller installed in slot 1. To power on the chassis from standby, press and hold the power inhibit button for 4 seconds. To power off the chassis, again press and hold the power inhibit button for 4 seconds.

Manual mode is used when you would like to manually control the inhibit state of the chassis. In Manual mode, driving the Remote Inhibit signal high or floating it will cause the chassis to be powered on. Driving the Remote Inhibit signal low or shorting it to ground will cause main power to be inhibited.

Note The Timing and Synchronization upgrade is required for access to the Remote Inhibit signal. Without this upgrade, a chassis in Manual mode will always be powered on when AC power is connected.
