strobe light and the second horn is located on the optional strobe light.
•
Alarm within the ECS—The ECS system notifies you of a fire alarm condition with an alarm alert on the
ECS screen.
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.
(Optional) Fire suppression system
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 jurisdiction requirements. Compliance with local codes is your
responsibility, and includes specific local requirements for initial and periodic inspections,
certifications, and maintenance.
Any additional local requirements are not covered as part of the option price or basic installation
and deployment services, unless specifically included in an executed Statement of Work.
WARNING: Fire suppression agents include a pre-discharge warning and evacuating system. In
the event of a fire, all protected space must be evacuated as soon as possible.
IMPORTANT: The fire suppression abort buttons that are located next to each personnel door
can be pressed to interrupt the 30-second fire suppression agent release delay for an additional
30 seconds. This button interrupts the countdown, but does not reset the 30-second fire
suppression agent release delay. The fire suppression agent release countdown will continue
when the abort button is released until the time is exhausted and the fire suppression agent is
released.
The fire suppression system contains conventional fire alarm control circuits and includes features required
for single or dual-hazard suppression release applications, including a low-toxicity agent. In the event of fire
suppression release, the suppression tanks must be refilled by a certified technician.

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.

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
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.
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.

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
Maintenance and Service Guide.

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
(http://www.nrc.gov/reading-rm/doc-collections/fact-sheets/fs-tritium.html).
