			system off and on

EPO modes

The EPO system has three operating modes:

•Armed—The EPO system is armed and operational.

•Test—The EPO system is in test mode and does not initiate during events that normally trigger an EPO.

•Bypass—The EPO system is non-operational and does not initiate during events that normally trigger an EPO.

EPO accidental activation

To help prevent accidentally pressing the EPO button and activating the EPO system, each EPO button is covered with a clear Lexan cover.

Battery backup during an EPO event

The following components are equipped with a UPS to help ensure that service is not interrupted during a loss of power to the HP POD 20c:

•ECS system

•VESDA air sampling smoke detection system (on page 21)

•(Optional) fire suppression system (on page 22)

•Emergency lighting in the HP POD 20c

IMPORTANT: All Critical IT UPS devices with batteries that exceed 700VA must be connected to the HP POD 20c EPO system, to ensure that the UPS batteries are disconnected during an EPO event. For more information on connecting UPS devices to the EPO system, see the HP Performance Optimized Datacenter 20c Maintenance and Service Guide.
