Changing AC Power Supplies

Owned by Jyothi KP

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 two power supplies activate as a redundant 1+1 configuration, as shown in the figure below. In a redundant configuration, power supplies are “hot-swappable,” allowing removal or replacement of one power supply without interrupting appliance operation and network services.

Redundant power supplies share the power load. If one power supply fails, the other automatically assumes the full load and the appliance sends a system alarm. This configuration minimizes the chance of system failure due to failure of an individual power supply.

When a power supply fails for any reason, the Grid Manager displays a power supply alarm. The Grid Status widget on the Dashboard of the Grid Manager also displays an error. The appliance sends an email notification and reports an SNMP trap. Figure below illustrates the replacement process for an AC power supply.

Removing an Infoblox 4005 series 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 an Infoblox 4005 series AC power supply, do the following:

  1. Disconnect the AC power cable from the power outlet.

  2. Gently press the catch-release lever toward the handle, grip the power supply handle, and pull the power supply unit out of the chassis as illustrated in the figure above.

  3. 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.

  4. Reconnect the power cable.
  5. If the power supply is fully seated, powered on, and operating properly, the LED glows steady green.
