The HP POD 40c G2 electrical busways can be configured for non-redundant power or redundant power. The HP POD 40c G2 can be installed as a single source 1N load by providing all required feeders from one common power source and from common switchboards and transformers. A 2N redundancy installation is configured by feeding the parallel power paths from independent power sources, switchboards, and transformers.

• Non-redundant power installation (1N load)—All eight busways are powered from the same power

feed.

Power, electrical, and controls 29

• Redundant power installation (2N load)—Four busways are powered from one power feed, and the

remaining four busways are powered from a different power feed.

Drop boxes

The internal electrical busways provide a location to connect each of the drop boxes, which then power the PDUs. Stagger the drop boxes on the electrical busways by connecting one drop box to busway #1 and connecting the next drop box to busway #2. A staggered configuration enables load balancing with the rack equipment and is necessary to ensure redundancy.

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. These capabilities enable you to connect, at your expense, with the stand-alone ECS system to monitor the operating parameters of the POD. It is your responsibility (or your representative's or agent's responsibility) to integrate this communication capability into any existing BMS or monitoring system.

CAUTION: To ensure that alarm conditions can be identified and resolved, HP recommends that

you remotely monitor all alarm conditions. Failure to monitor the alarm conditions can cause delays in appropriate action during an alarm condition.

Using the ECS

HP recommends connecting the HP POD 40c G2 to your facility BMS and establishing communication through the Ethernet cable connected to the external communications box. For more information, see "Configuring the ECS (on page 37)."

The HP POD 40c G2 ECS is a Windows-based system with the following features:

• Intel Core Duo processor

• 15-inch touchscreen

• 512 MB RAM

• 80 GB hard drive

• 24 V DC power supply

• One serial port

• Four USB ports

• 1x10/100 BASE-T and 1x10/100/1000 BASE-T Ethernet connectors

The standard ECS protocol, Modbus TCP/IP, is a data communication protocol for building automation and control networks. Connecting across different protocols might require additional engineering labor and coordination between your in-house control manufacturer and HP. It is your responsibility to make the connection between the HP POD 40c G2 and a BMS system.

The ECS provides the following:

• A supported communication interface that can monitor and control certain HP POD 40c G2

components remotely

• Immediate notification of all supported alarm messages

Environmental control system 33

By connecting your HP POD 40c G2 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 40c G2 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 (on page 63).

Satellite control boxes

The satellite control boxes facilitate communication from the ECS to the cooling system fans. Each satellite control box controls the fans in the zone that corresponds with its location.

The HP POD 40c G2 has six satellite control boxes, one box per cooling zone. Top view shown

Sensors

The HP POD 40c G2 has several temperature and pressure sensors that monitor the environmental factors and communicate data back to the ECS.

• The values from the temperature sensors are calculated together to determine an average temperature

• The pressure sensors measure the differential pressure between the hot aisle and the cold aisle.

HP POD 40c G2 cooling system theory of operation

CAUTION: Using contaminated supply water can cause decreased cooling capacity or

disruption in service. The supply water must meet the guidelines stated in the HP Performance Optimized Datacenter 40c G2 Site Preparation and Requirements Guide. Damage caused by

The HP POD 40c G2 has 12 heat exchangers configured into 6 zones that maintain temperature and cool the equipment installed in the HP POD 40c G2. The HP POD 40c G2 receives chilled water from your facility, cycles the water through the heat exchangers to cool the air, and then the fans circulate the cool air throughout the HP POD 40c G2.

A predetermined differential pressure setpoint between the hot aisle and the cold aisle is factory set. Do not alter the setpoint without consulting HP. The fan speeds are regulated to maintain the differential pressure between the hot and cold aisle and hot aisle temperature. For more information, see "Fans (on page 59)."

The HP POD 40c G2 chilled water flow rate is regulated by the ECS Flow Control Valve that is installed on the POD chilled water return header. The ECS system opens and closes this valve to maintain the differential temperature between the POD supply and return chilled water header temperature.

For more information on the cooling system, see the HP Performance Optimized Datacenter 40c G2 Maintenance and Service Guide.

contaminated supply water is not covered by the warranty.

Water supply temperature

The temperature of the water supplied to the HP POD 40c G2 must be 13ºC to 24ºC (55ºF to 75ºF). Freezing water can cause a blockage and damage to the POD.

Cooling system 56

The minimum HP server inlet temperature is 10°C (50°F). For non-HP equipment, consult the documentation

subject to freezing temperatures, an additive such as glycol might be necessary to lower

Drains

Water from natural condensation will form. Condensation from the heat exchangers flows to the condensation drains at each end of the HP POD 40c G2.

WARNING: Water that drains around the HP POD 40c G2 can cause a potential slip hazard.

Use caution where slip hazards are present.

Cooling system 60

The HP POD 40c G2 has two heat exchanger condensate drains.

IMPORTANT: You might need to connect the HP POD 40c G2 drain directly to the local storm or

sanitary drain, depending on the local jurisdiction.

If your HP POD 40c G2 is located indoors, you can connect to an external drain line. If your HP POD 40c G2 is located outdoors, the drained water drains out the back of the HP POD 40c G2.

HP recommends connecting the condensate drains on the HP POD 40c G2 to a facility drain to prevent collection of water near the HP POD 40c G2.

Leak detection

The HP POD 40c G2 includes six heat exchanger condensate drains. One drain pan sensor is located in the drain tray below each set of heat exchangers.

Two sensors are also located in the header drain pans, one in cooling zone 2 and one in cooling zone 5. 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 40c G2 ECS, indicating a possible leak.

For more information on leak detection, see the HP Performance Optimized Datacenter 40c G2 Maintenance and Service Guide.
