Repair Procedures

Recommended Power Off

Step 1

Step 2

Emergency

Power-Off

Use these procedures when removing or installing components:

Power supplies and fans (page 5-2)

Alarm panel (page 5-4)

Power distribution panel (page 5-5)

Module removal (page 5-7)

Hot swap (page 5-10)

Hot growth (page 5-13)

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:

Shut down all software operations (JetVision, JetCraft).

Flip the rocker switch in the rear of the shelf to the “0” position.

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.
