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

The PT-1400 ships with one AC power supply. When 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 14 illustrates the process of replacing an AC power supply.
Each power supply weighs about one pound (0.454 kg). The faceplate of the power supply contains a power LED and a power switch. Each AC power supply provides a dedicated power outlet.

Note: If your appliance comes with one power supply and an empty module, ensure that the power supply is in the PSU #1 slot and the empty module in the #2 slot. You cannot switch them.


Figure 14 Removing a PT-1400 AC Power Supply
 

To replace the PT-1400 AC power supply, do the following:

  1. Turn off the power circuit to the appliance's AC power supply.
  2. Disconnect the AC power cable from the appliance's AC power supply.
  3. Gently press the black 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 14.
  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. Turn on the power supply. If it is fully seated, powered on, and operating properly, the LED glows steady green.

You can order an additional power supply to set up a redundant 1+1 configuration, as shown in Figure 15. The power supplies are "hot-swappable," so you can remove or replace one power supply without interrupting appliance operation and network services.
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.
