Life safety overview

The HP POD 240e NA has multiple life safety systems that work together to protect the HP POD 240e NA equipment and personnel. The following life safety systems are included on the HP POD 240e NA:

•EPO system (on page 19)

•Fire detection system (on page 22)

•Emergency egress (on page 24)

•Facility connections to ECS ("Facility connections to the ECS" on page 35)

EPO system

If the HP POD 240e NA must be shut down during an emergency, the EPO system automatically powers off the HP POD 240e NA, activates the EPO indicator on the ECS panel door, and changes the EPO status light tree that is located on the POD exterior to red.

To be sure that all rack-mounted UPS devices are shut down during an EPO event, verify that each rack-mounted UPS device is connected to the HP POD 240e NA EPO system.

The EPO system can be activated two ways:

•Excessive high temperature in the hot aisle—The HP POD 240e NA includes two thermisters. If both thermisters reach 60°C (140°F), an EPO shutdown is triggered automatically.

Side view

•Manual initiation—To manually trigger an EPO shutdown, press any of the EPO buttons. There are EPO buttons located next to the personnel access doors in the POD.

For the location of EPO buttons, see "Life safety component identification (on page 10)."
