Life safety systems
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)."

Life safety systems
21
Fire detection system
Each HP POD 240e NA is equipped with a fire alarm panel that is integrated with the fire detection system.
The fire system is designed as a stand-alone system, but the system can also interface with customer site fire
alarm systems. Customer site connections are the responsibility of the customer. Consult with HP for
connection locations.
The fire protection system includes:
•
VESDA air sampling smoke detection system (on page 22)
•
Manual fire pulls (on page 22)
•
Fire alarm panel (on page 23)
•
Fire alarm indicators (on page 23)
VESDA air sampling smoke detection system
CAUTION: Excess dust within the HP POD 240e NA 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 piping that runs throughout the HP POD 240e NA includes inlets for smoke sampling. The
VESDA uses a high-efficiency aspirator to continuously draw in air from the HP POD 240e NA and circulate
the air through a dual-stage filter:
•
Stage 1—A filter removes dust and dirt from the air sample.
•
Stage 2—An ultra-fine filter removes remaining contaminants in the air sample.
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. The VESDA system cycles through two levels if smoke is detected:
•
Level 1—Smoke concentration reaches the first setpoint, and the VESDA system sends an alarm signal
indicating that a fire might exist.
•
Level 2—Smoke concentration reaches the second setpoint, and the VESDA system indicates that a fire
exists in the HP POD 240e NA.
IMPORTANT: The VESDA filter must be changed regularly to be sure that smoke detection
readings are accurate. For more information about changing the VESDA filters, see the HP
Performance Optimized Datacenter 240e NA Maintenance and Service Guide.
Manual fire pulls
The HP POD 240e NA has six fire pulls; two in each aisle. They are located in the life safety switch cabinet
next to each personnel door of the HP POD 240e NA.
Manually activating a fire pull does the following:
•
Triggers a fire alarm
•
Activates the fire alarm system horn and strobe lights
Life safety systems
22
Fire alarm panel
The fire alarm panel is located in the control cabinet in IT section A and receives signals from the VESDA or
manual fire pulls if an alarm condition exists. If an alarm condition does exist, the fire alarm panel activates
the fire alarm indicators and sends a signal to the site fire alarm system, if installed.
The fire alarm panel also has a battery backup system that provides backup power to the fire detection
system in the event of power loss to the HP POD 240e NA.
The control panel includes the following components:
•
Alarm status LED
•
Trouble status LED
•
Input status LED
•
Output status LED
•
Acknowledge button
•
Alarm Silence button
•
System Reset button
Fire detection sequence of operations
There are two initiation sequences for the fire detection system, automatic (VESDA) initiation and manual
initiation. The fire strobe light is activated by either initiation sequence.
The fire alarm horn will sound in a temporal mode for any VESDA or manual fire pull initiation.
The fire system operator panel indicates which initiation sequence is active, using the indicator lights and a
panel alarm. These signals are also available to the site BMS system, if they are connected.
VESDA initiation
When smoke is detected, the VESDA fire detection system cycles through two levels, as described below.
•
Level 1—Indicates the potential for a fire is present. The strobes illuminate and the horns sound.
•
Level 2—Indicates that a fire exists. VESDA level 1 might have be reached; the strobes illuminate and
the horns sound.
Manual initiation
Manual initiation triggers the fire alarm, causes the fire strobe lights to illuminate, and sounds the horn.
Fire alarm indicators

Power, electrical, and controls
Site electrical system
To be sure that the POD solution is completely and safely integrated with your facility, HP requires that you
complete the following actions for the installed electrical system prior to the installation of the HP POD
solution:
•
Short circuit analysis
•
Arc flash study
•
Circuit breaker coordination study
These actions must be performed for all associated parts of the electrical power train. The majority of the
details and factors that are required to complete these studies are associated with the existing installed
facility infrastructure.
CAUTION: Failure to complete these studies can cause serious issues with the electrical
integration of the POD into your electrical system.
Power safety
WARNING: To avoid the risk of personal injury or loss of life, all personnel must comply with PPE
requirements when opening or working inside areas of the HP POD 240e NA that are marked as
hazardous voltage, per NFPA 70E in accordance with NEC (NA) and IEC (EMEA and APJ).
Grounding and bonding
WARNING: To avoid the risk of personal injury or electric shock, the HP POD 240e NA must be
properly earthed (grounded), and each of the individual sections must be bonded together per
NFPA 70 in accordance with NEC (NA) and IEC (EMEA and APJ).
The HP POD 240e NA must be properly earthed to be sure that a common return path for electric current
exists, limit the build-up of static electricity, and absorb an unlimited amount of current without changing its
potential. To properly ground the HP POD 240e NA to the earth, you must connect the POD to building steel,
a ground rod, or a properly installed ground well that is connected to a building’s grounding system. The
grounding electrode conductor connection point is located on the cold aisle side adjacent to the power
cabinet.
A certified electrician must test and verify the HP POD 240e NA is properly grounded.
Grounding
The HP POD 240e NA includes the following types of grounding.
Earth ground
Power, electrical, and controls
25
Side view shown
Bonding
All structural sections of the HP POD 240e NA are bonded by connecting all metallic, non-current carrying
items throughout the HP POD 240e NA to protect from electric shock. If all steel-to-steel areas are bonded to
one another, each object then has the same electrical potential which ultimately dissipates any high voltage
or shock across the entire HP POD 240e NA, minimizing any effects from a lightning strike, per NFPA 70 in
accordance with NEC (NA) and IEC (EMEA and APJ).
Lightning protection
The HP POD 240e NA structure and internal components are all bonded together. A common grounding
electrode conductor connection point is provided. Proper bonding and grounding of the HP POD 240e NA
minimizes the effects of a lightning strike. A surge protection device is provided on the HP POD 240e NA
input connection to protect the HP POD 240e NA electrical system from voltage transients. If your site is in an
area that is subject to frequent lightning strikes, the HP POD 240e NA must be protected in accordance with
NFPA 70 (NA) and IEC (EMEA and APJ). HP recommends that you contact a certified lightning protection
consultant.
Capacities
Each HP POD 240e NA is unique and the specific power and cooling capacities vary for each POD that uses
Adiabatic cooling. For specific capacity information, see your HP Performance Optimized Datacenter 240e

Environmental control system
Environmental control system overview
The ECS is a stand-alone control system developed for the HP POD 240e NA. The ECS does not require
external connections with an external site system, BMS, public or private internet site, cloud, or wireless
system to control the POD operation properly.
The ECS is designed to use Modbus TCP/IP connections to retrieve a variety of data. These capabilities
connect to the stand alone ECS system to monitor the operating parameters of the POD at your expense. 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 be sure 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 240e NA 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 38)."
The HP POD 240e NA ECS is a Microsoft Windows-based system.
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 240e NA and a BMS system.
The ECS provides the following:
•
A supported communication interface that can remotely monitor and control certain HP POD 240e NA
components.
•
Immediate notification of all supported alarm messages.
By connecting your HP POD 240e NA to a BMS system, you can monitor the various parameters and alarms.
For more information, see "Navigating the ECS interface (on page 42)." 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 240e NA ECS data can be sent to and
viewed from a set of IP addresses on a host computer. The ECS communicates through an Ethernet
cable connected to the demarcation box (on page 67).
Environmental control system 34

AHU system
Overview
The POD AHU systems are designed to condition the air in a portable, containerized computer room, and
are installed directly on top of the HP POD 240e NA. The HP POD 240e NA includes a total of four cradles,
each holding 3 Adiabatic units, for a total of 12 Adiabatic units.
The AHU system requires a potable water source and HP highly recommends installing a filter to be sure that
water is free of particles. For more information about water requirements, see the HP Performance Optimized
Datacenter 240e NA Site Preparation and Requirements Guide.
Adiabatic components
Each Adiabatic unit is housed in a NEMA 3 rated steel frame cabinet that is rated for outdoor use. The
exterior of the cabinet is coated with a durable finish to protect against corrosion. Access panels are located
on the front and on the rear of the cabinet for easy access to all of the components. The access panels are
safety interlocked with the power disconnect switch to prevent the removal of the panel when the switch is in
the ON position. The power disconnect switch must be turned OFF to gain access to the electrical
compartment.

Adiabatic media
Each Adiabatic unit contains three Adiabatic media, each with its own solenoid water supply valve. An
outside source of water must be provided to saturate the media.
HP recommends potable water as the main water source for the media.
AHU theory of operation
Damper operation
Each Adiabatic unit is equipped with louvered dampers that control the airflow through the unit. To control
the environment inside of the HP POD 240e NA, the dampers work together to humidify dry outside air, as
needed.
An external source of water must be provided to saturate the evaporative media. When the HP POD 240e
NA begins operation, the supplied water is pumped through the pipes and out of the nozzles from the
reservoir to the top of the evaporative media where it passes through spray nozzles onto the top of the
evaporative media. The air that is pulled in through the media by the POD fans is now conditioned.
The controller sends an analog output signal to operate the outside air damper (1) by modulating it. Next, the
bypass damper (2), the isolation damper (3), and the hot aisle return damper (4) are controlled to optimize
the balance of outside air with humidified air in order to maintain the conditions in the IT section. The
AHU system 62
isolation damper (3) is used to isolate the dry side of the Adiabatic unit from the wet side during cold weather
operation.
Below freezing damper operation
The isolation damper (3) is completely closed, so that sub freezing air cannot get to the wet media. The
bypass damper (2) is completely open, enabling a path for the cold, dry air to enter the IT sections. The
outside air damper (1) and hot aisle return damper (4) moderate to maintain a set temperature within the IT
sections.
If the humidity within the HP POD 240e NA gets too low, water is added to the media to maintain the low RH
humidity parameter, unless the ECS is set to Allow Low RH.
For more information on winterizing the HVAC/ Adiabatic units, see "Preparing the HVAC units for winter."

Hot weather damper operation
The hot aisle return damper (4) is completely closed, so that the air returning from the hot aisle is not
recirculated through the Adiabatic unit. The outside air damper (1) and the isolation damper (3) are both
completely open to optimize airflow efficiency. The bypass damper (2) modulates to maintain the humidity
parameter.
Water is added to the media to cool the outdoor air, while still maintaining the humidity in the IT sections
below the max RH parameter.
Side view shown
Exhaust fan operation
AHU system 64
The HP POD 240e NA is equipped with 10 exhaust fans that remove heated air from the hot aisle. The
exhaust fans feature an integrated monitoring function to protect the motor and electronics against damage
from jamming, phase loss, or overheating.
If any of the following failure conditions occur, the motor automatically stops and an alarm is signaled:
•
Locked rotor
•
Low main supply voltage
•
Loss of a phase
•
Over-heating of the exhaust fan electronics
•
Over-heating of the exhaust fan motor
For more information about the exhaust fan, see the HP Performance Optimized Datacenter 240e NA
Maintenance and Service Guide.
Side view shown
Static pressure control
The control of static pressure is used to be sure that the airflow from the cold aisle of the IT sections across the
rack and into the hot aisle of the HP POD 240e NA remains constant. The pressure in the hot aisle is
controlled to external ambient pressure, and the IT sections are slightly higher than the external ambient
pressure.
The static pressure is controlled to a default parameter of 0.1 in H2O above external ambient pressure in the
cold aisle, which cannot be adjusted by a customer.
