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.
Caution: Never remove a correctly functioning power supply in a live system. Removing the power supply from a correctly operating Infoblox appliance appliance can cause a complete failure of the appliance and require an RMA (Return Material Authorization).
The Network Automation NT-2200 ships with two AC power supplies in a redundant 1+1 configuration. In a 1+1 configuration, when a power supply fails for any reason, the other assumes the full load automatically and the Infoblox GUI displays a power supply alarm. The appliance can also be configured to send an email notification and to report an SNMP trap when such events occur in a 1+1 configuration. This configuration minimizes the chance of system failure due to failure of an individual power supply.
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 the Network Automation NT-2200 AC power supply, do the following:
- Disconnect the AC power cable from the power outlet.
- Turn the thumbscrew counter-clockwise to release the power supply.
- 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.
- 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.
- Reconnect the power cable.
- If the power supply is fully seated, powered on, and operating properly, the LED glows steady green.
