In its DC power configuration, the PT-1400 ships with two redundant, auto-switching DC power supplies. The power supplies are "hot-swappable," so you can remove or replace one power supply without interrupting appliance operation and network services.

To replace a DC power supply, do the following:
- Disconnect the DC power cable from the power outlet on the external transformer.
- Disconnect the power cable from the power supply.
- Gently push back the blue catch-release lever toward the handle, grip the power supply handle, and pull the power supply unit out of the chassis as illustrated in Figure 16.
- Place the replacement power supply into the bay and push it forward until it is fully seated in the chassis. The red catch-release lever will gently click into place.
- Reconnect the power cable. If the power supply is fully seated and operating properly, the LED glows steady green.
