Life safety systems Life safety overview The HP POD 20c has multiple life safety systems that work together to protect the HP POD 20c equipment and personnel.
For the location of EPO buttons, see "Life safety component identification (on page 9)." The EPO system must be reset before you can power up and restart the HP POD 20c. To reset the EPO system: 1. Verify that the key control for the EPO mode is in the Armed position. 2. Press the white EPO Reset button. If you triggered the EPO system manually, you must reset the EPO button that you pressed to the Active position.
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.
• Level 2—Smoke concentration reaches the second setpoint, and the VESDA system indicates that a fire exists in the HP POD 20c and sends an activation signal to the fire suppression system. IMPORTANT: The VESDA filter must be changed regularly to ensure accurate smoke detection readings. For more information about changing the VESDA filters, see the HP Performance Optimized Datacenter 20c Maintenance and Service Guide.
CAUTION: The POD fire suppression system is manufacturer designed, engineered, and installed to comply with national standards. However, HP does not certify that the installed fire suppression system meets all local jurisdictional requirements. Compliance with local codes is your responsibility, and includes specific local requirements for initial and periodic inspections, certifications, and maintenance.

Environmental control system Environmental control system overview The ECS developed for the HP water-cooled POD is a stand-alone control system that requires no external connections with an external site system, BMS, public or private Internet sites, cloud, or wireless system to properly control the POD operation. The ECS includes Modbus TCP/IP connections through which a variety of data can be retrieved.
By connecting your HP POD 20c to a BMS system, you can monitor the various parameters and alarms. For more information, see "Navigating the ECS interface (on page 41)." The complete list of parameters and alarms that can be monitored will be discussed with your facilities personnel. IMPORTANT: If your site does not have a BMS, HP POD 20c ECS data can be sent to and viewed from a set IP address. Communication occurs through an Ethernet cable that is connected to the demarcation box.
Top view shown Temperature sensors The values from the temperature sensors are calculated together to determine an average temperature for each aisle of the HP POD 20c. Cold aisle temperature sensors Three temperature sensor probes are located in the cold aisle of the HP POD 20c. These temperature sensors monitor the temperature in various locations throughout the cold aisle and report data to the ECS.
Side view shown Heat exchanger temperature sensors There are two contact temperature sensors per heat exchanger. One temperature sensor is located on the inlet supply piping and one temperature sensor is located on the outlet return piping. These sensors measure water temperature and report data to the ECS.

Top view shown Condensation management CAUTION: To maintain accurate environmental conditions inside the HP POD 20c, do not leave the HP POD 20c doors open during operation. The heat exchanger drip trays collect condensation that forms on the heat exchangers. This collected condensate drains out of the HP POD 20c through the heat exchanger condensate drain. HP recommends connecting the condensate drain on the HP POD 20c to a facility drain to prevent collection of water near the HP POD 20c.
Water from natural condensation forms. Condensation from the heat exchangers flows to one of the two condensation drains located at each end of the hot aisle. IMPORTANT: You might need to connect the HP POD 20c condensate drains directly to the local storm or sanitary drain, depending on the local jurisdictional requirements.
There should be no water in the header drain pan and the drain pan should always remain dry. Some amount of condensation water can always be expected in the heat exchanger drain pans. If an excessive amount of condensation water accumulates in a drain pan, an alarm is triggered and sent through the HP POD 20c ECS, indicating a possible leak. For more information on leak detection, see the HP Performance Optimized Datacenter 20c Maintenance and Service Guide.
IT networking and communications Networking Connecting the HP POD 20c to the facility network is a vital part of ensuring the functionality of the various communication systems. See the HP Performance Optimized Datacenter Networking Guide for more information. All connections are the responsibility of the customer.
