VESDA air sampling smoke detection system
CAUTION: Excess dust within the HP POD 40c G2 can cause the VESDA smoke detector to trigger a fire alarm.
The VESDA system features a single zone laser scan early warning smoke detector to provide the earliest warning of a potential fire.
The orange VESDA conduits that run throughout the HP POD 40c G2 include inlets for smoke sampling. The
VESDA uses a high-efficiency aspirator to continuously draw in air from the HP POD 40c G2 and circulate the air through a dual-stage filter:
• Stage 1—Dust and dirt are removed from the air sample.
• Stage 2—Remaining contaminants in the air sample are removed with an ultra-fine filter.
After the air passes through the dual-stage filter, it enters a calibrated detection chamber where a laser scans the air sample for the presence of smoke. When the smoke concentration reaches the first setpoint, the
VESDA system will send an alarm signal indicating that a fire might exist. When the smoke concentration reaches the second setpoint, the VESDA system indicates that a fire does exist in the HP POD 40c G2 and sends an activation signal to the fire suppression system.
Life safety systems 19
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 40c G2 Maintenance and Service Guide.

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.
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.

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 for each aisle of the HP POD 40c G2.
• The pressure sensors measure the differential pressure between the hot aisle and the cold aisle.

Cooling system
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 contaminated supply water is not covered by the warranty.
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
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.
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 for that equipment.
Water quality requirements and specifications
The following are the water quality requirements and specifications:
• Closed-loop water must not contain any lime scale deposits or loose debris.
• The temperature of the chilled water supplied to the HP POD 40c G2 must be 12ºC to 24ºC (55ºF to
75ºF).
CAUTION: Freezing water can cause a blockage and damage to the unit. In outside locations that are subject to freezing temperatures, an additive such as glycol might be necessary to lower the freezing point. However, since the heat transfer potential of water with glycol is lower, the HP
POD 40c G2 must be de-rated accordingly.
IMPORTANT: The chilled water system piping and heat exchangers must be drained completely, and then purged using compressed air when storing or transporting at or below freezing temperatures.
IMPORTANT: Operating the chilled water system at the higher end of the acceptable range decreases the overall thermal capacity of the POD.
Acceptable water quality specifications
Water must be maintained per the following acceptable water quality standards.
Parameter Range pH 8.0–10
Specific conductance at 25ºC (77ºF) 10–2500 µmhos

Condensation management
CAUTION: To maintain accurate environmental conditions inside the HP POD 40c G2, do not leave the HP POD 40c G2 doors open during operation.
The heat exchanger drip pans collect any condensation that forms on the heat exchangers. The collected condensate drains out of the HP POD 40c G2 through the heat exchanger condensate drains. 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.
The HP POD 40c G2 has two 3.175 cm (1.25 in) condensate drain outlets, one located at each end of the hot aisle of the HP POD 40c G2 directly connected to the heat exchanger drip pans. The HP POD 40c G2 has two drains for the water main supply and return lines located on the front of the POD.
To avoid excessive buildup of condensate and to conserve energy, raise the cooling water temperature to above the dew point to manage condensation while maintaining the necessary cooling capacity.
Drains
WARNING: Water that drains around the HP POD 40c G2 can cause a potential slip hazard.
Use caution where slip hazards are present.
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.
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

Regulatory compliance notices 77
Regulatory requirements for EXIT signs
Manufacturers of tritium EXIT signs are “specific licensees,” meaning they are licensed by the NRC or an
Agreement State. The signs are considered “generally licensed devices,” because they are inherently safe enough to be handled or used by anyone with no radiation training or experience. Although purchasers – known as “general licensees” – do not need authorization from the NRC or a state regulatory agency to possess the signs, they are subject to certain regulatory requirements regarding handling, transfer or disposal of the signs. For more information, see the NRC website
( http://www.nrc.gov/reading-rm/doc-collections/fact-sheets/fs-tritium.html#_edn2 ). They are also subject to NRC or Agreement State inspection and enforcement action (including fines) for violating those requirements. Manufacturers must inform purchasers of the EXIT signs of the regulatory requirements for generally licensed devices. The general licensee is required to designate an individual responsible for complying with the regulatory requirements.
Under NRC regulations, a general licensee using tritium EXIT signs:
• must NOT remove the labeling or radioactive symbol, or abandon a sign;
• must properly dispose of an unused sign (see below);
• must report to the NRC or the appropriate Agreement State any lost, stolen or broken signs;
• must inform the NRC or an Agreement State of a name change, change of address or replacement of a general licensee’s designated representative;
• must NOT give away or sell the sign to another individual, company or institution unless the device is to remain in use at its original intended location; in such a case, the transferor is to notify the recipient of the regulatory requirements and must notify the NRC or Agreement State of the transfer within 30 days.
Tritium EXIT signs must NOT be disposed of as normal trash. To dispose of a sign properly, a general licensee must transfer the sign to a specific licensee. This would typically be a manufacturer, distributor, licensed radioactive waste broker, or a licensed low-level radioactive waste disposal facility. These facilities may charge a fee for this service.
Within 30 days of disposing of a sign, the general licensee is required to file a report to the NRC or
Agreement State that includes:
• the device manufacturer’s (or distributor’s) name, model number and serial number;
• the name, address, and license number of the person receiving the device; and
• the date of the transfer.
Reports should be sent to Director, Office of Federal and State Materials and Environmental Management
Programs, ATTN: GLTS, U.S. Nuclear Regulatory Commission, Washington, D.C. 20555-0001.
For more information, see the Fact Sheet on Tritium EXIT Signs on the NRC website

A general term, including fittings, devices, appliances, luminaires, apparatus, machinery, and the like used as a part of, or in connection with, a modular data center. (Source: NEC.) fuse, branch circuit type
A fuse of Class CC, G, H, J, K, L, R, and T. These fuses are able to provide branch circuit protection. fuse, supplementary type
Miscellaneous type and miniature type fuses. These fuses are able to provide supplementary protection only. labeled
Equipment or materials to which has been attached a label, symbol, or other identifying mark of an organization that is acceptable to the authority having jurisdiction and concerned with product evaluation, that maintains periodic inspection of production of labeled equipment or materials, and by whose labeling the manufacturer indicates compliance with appropriate standards or performance in a specified manner. listed
Equipment, materials, or services included in a list published by an organization that is acceptable to the authority having jurisdiction and concerned with evaluation of products or services, that maintains periodic inspection of production of listed equipment or materials or periodic evaluation of services, and whose listing states that either the equipment, material, or service meets appropriate designated standards potential of not more than 42.4 V (DC or peak) supplied by a primary battery or by an isolated secondary circuit, and where the current capacity is limited by an overcurrent device, such as a fuse, or by the inherent capacity of the secondary transformer or power supply, or a combination of a secondary winding and an impedance. A circuit derived from a line-voltage circuit by connecting a resistance in series with the supply circuit to limit the voltage and current is not identified as a low-voltage limited energy circuit. or has been tested and found suitable for a specified purpose.
The means for identifying listed equipment might vary for each organization concerned with product evaluation, some of which do not recognize equipment as listed unless it is also labeled. Use of the system employed by the listing organization allows the authority having jurisdiction to identify a listed product. overload protection
Protection required for motor circuits that will operate to prohibit excessive heating due to running overloads and failure to start.
PLC programmable logic controller
PPE personal protective equipment structure
Enclosure of sufficient size to enable entry of personnel.
