Replacing a Power Supply

This document is for administrators who need to replace a power supply. Use this document to diagnose and replace a failed power supply in Google Search Appliance models G100, G500, and GB- 7007:

Note: The power supplies in the G100 and GB-7007 are replaceable if the Appliance ID starts with T2, T3, or T4. View the Appliance ID from the Admin console About page. The Appliance ID also appears on labels on the search appliance chassis.

Overview

Replacing a power supply consists of:

  1. Verifying the current state of the power supply.
  2. Contacting Google Customer Support to get authorization for a replacement power supply.
  3. Replacing the power supply in the search appliance, processing unit, or storage unit with the new power supply from Google.
  4. Verifying that the new power supply works correctly.

Working with Power Supplies

Diagnose and replace a power supply from the rear of a search appliance, processing unit, or storage unit while the device is in its rack and running. The power supplies are hot-swappable, which means that there is no service interruption during the process of changing a power supply. Exercise caution when working around powered devices to prevent injury to you or damage to the equipment.

You need at least 14 inches (36 centimeters) of free space behind a search appliance, processing unit, or storage unit to remove a power supply. If there is not enough space behind the device to remove the power supply, remove the attachment screws at the front of the rack so that the device can slide out far enough to remove the power supply. Remove the attachment screws using a #2 Phillips-head screwdriver.

Each search appliance comes with a key for removing the front bezel panel.

Important: If a power supply fails, leave it in the search appliance, processing unit, or storage unit until you are ready to install the new replacement power supply. You can optionally remove the power cord from the failed power supply.

Dispose of the failed power supply in accordance with the recycle or disposal policy for your organization, locality, state, or country government.

Verifying the Power Supply Status

You can verify the current status of the power supplies from the rear of the search appliance, processing unit, and storage unit. At the rear of the device there is an indicator light on each power supply that shows its operating status.

On the G100 and G500 units, the indicator light is inside the pull handle, so the entire pull handle lights up. 

If a power supply has an amber indicator light, the power supply has failed. If you see a power supply failure, contact Google Customer Support (see Contacting Customer Support).
