Changing AC Power Supplies

Note: Before changing the power supply, make sure that it is securely cabled. An apparently failed power supply may simply be improperly connected to its power source.

The PT-2200 ships with two AC power supplies in a redundant 1+1 configuration. When the appliance contains two functioning power supplies, they share the power load. If one power supply fails, the other assumes the full load automatically and the appliance sends a system alarm. This configuration minimizes the chance of system failure due to failure of an individual power supply. The power supplies are hot-swappable so you can remove or replace one power supply without interrupting appliance operation and network services.
When any of the power supply fails for any reason, the Infoblox GUI displays a power supply alarm. The Grid Status widget on the Dashboard of the GUI also displays an error. The appliance sends an email notification and reports an SNMP trap. Figure 17 illustrates the process of replacing an AC power supply.

Each power supply weighs about one pound (0.454 kg). The faceplate of each power supply contains a power LED and a dedicated power outlet.
To replace a PT-2200 AC power supply, do the following:

1. Disconnect the AC power cable from the power outlet.
2. Turn the thumbscrew counter-clockwise to release the power supply.
3. Gently press the catch-release lever toward the thumbscrew, grip the power supply handle, and pull the power supply unit out of the chassis as illustrated in Figure 17.
4. Place the replacement power supply into the bay and push it forward until it is fully seated in the chassis. The catch-release lever will gently click into place.
5. Reconnect the power cable.
6. If the power supply is fully seated, powered on, and operating properly, the LED glows steady green.
