Leak detection maintenance

WARNING: To reduce the risk of electric shock or damage to the equipment, use extreme caution when removing and replacing components that involve water around the electrical equipment. There is great risk of electrical shock when water is used near electricity.

CAUTION: If a serious leak develops, shut down the POD immediately and isolate the chilled water cooling system from the site. Contact HP immediately to initiate a field service call. Do not attempt to repair the chilled water cooling system. Attempting to self-repair the chilled water cooling system during the warranty or service contract period shifts all liability to you.

IMPORTANT: HP recommends shutting down the POD after a leak is detected. For more information, see "Power down procedure" in the user guide.

Non-isolable leak detection

A non-isolable leak is a leak from the main supply line or the return header.

To repair a non-isolable leak:

1.Power down all IT equipment.

2.Re-direct the leaking water away from the IT equipment.

3.Repair the leak or contact HP if you are still within your service contract.

Isolable leak detection

An isolable leak is any type of leak that does not occur from the main supply line or the return header. To repair an isolable leak:

1.Inspect the zone indicated on the ECS Status Overview screen. You might need to inspect each zone condensate drain pan to determine the exact location of the leak.
