Power Off
Power Off cuts input power to all power supplies. In dual-
configured systems, both domains lose input power. This
procedure is recommended when powering off the CPX:
Step 1 Shut down all software operations (JetVision, JetCraft).
Step 2 Flip the rocker switch in the rear of the shelf to the “0” position.
Emergency
Power-Off
In the event of an emergency, flip the rocker switch in the rear of
the chassis to the “0” position. This removes input power from the
power supplies and results in an abnormal system shutdown.
Voice/Data Interruption
Emergency power-off interrupts all traffic through the CPX.
