CAUTION: If any racks contain empty RU space, use the HP POD 40c NA filler panels to
maintain the efficiency of the HP POD 40c NA thermal system. Filler panels are available from HP
in 10-pack quantities (part number AQ682A) and 100-pack quantities (part number AS993A).
For more information about racks and network cabling, see the HP Performance Optimized Datacenter
Networking Guide.
Illustrated parts catalog

Aisle clearances
Cold aisle clearance
The maximum protrusion of any installed IT component directly impacts the available cold aisle clearance for
removal and replacement of other IT components. Maximum component depth must follow the clear aisle
distance calculations. The following figure shows how to calculate this distance.
The maximum rack face-to-cold aisle wall distance is 39.5 inches. In the figure, X represents any protrusion
into the cold aisle starting from the rack face of the installed IT component (for example, the bezel). Y
represents cold aisle clearance. The cold aisle clearance dictates the maximum depth (D) of any installed IT
component. To find the maximum cold aisle clearance, calculate 100.33 cm (39.5 in) - X = Y.
IMPORTANT: As the value for X increases, the value for Y decreases, which also decreases the
maximum depth allowed for an installed component.
Illustrated parts catalog
13
Hot aisle clearance
Hot aisle clearance is defined as the distance from the rear of the rack to the hot aisle wall. The reference
distance of 2.54 cm (16 in) must be considered when selecting IT infrastructure that will populate into the hot
aisle.
Replaceable components
Each HP POD 40c NA is unique and the specific replaceable components vary for each POD. For specific
replaceable component information, see the Operations and Maintenance Manual for the HP Performance
Optimized Datacenter 40c North America.

Safety considerations
The HP POD 40c NA is listed to the UL 69050 standard as an Information Technology Product and Classified
according to the NEC, NFPA-70, 2008.
The HP POD 40c NA is not suitable for long term personnel occupancy.
The safety information is specific to the people operating and maintaining the components of the HP POD
40c NA.
IMPORTANT: All plumbing to and from the HP POD 40c NA must be completed by a licensed
plumber.
IMPORTANT: All wiring in and around the HP POD 40c NA must be completed by a licensed
electrician.
Operator safety
The HP POD 40c NA is not habitable or suitable for human occupancy. The HP POD 40c NA is Listed as a
Product that provides service access areas for periodic maintenance and service. These areas must be
controlled and available for use only by owner-authorized personnel and qualified personnel who are
trained in the maintenance and service of the HP POD 40c NA components.
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 40c NA that are marked as
hazardous voltage, per NFPA 70E in accordance with NEC (NA) and IEC (EMEA and APJ).
WARNING: To avoid the risk of personal injury, hearing protection must be worn at all times
when working inside the HP POD 40c NA.
WARNING: To avoid the risk of personal injury or damage to the equipment, do not insert
anything inside the electrical busways, except for the approved HP busway drop boxes.
Before completing the installation of the HP POD 40c NA, the customer, or a designated agent, is
responsible for completing any Environmental Health and Safety evaluation of the HP POD 40c NA or any
attached structural component purchased through HP. The customer, or their designated agent, must also
complete an arc flash assessment and breaker coordination study of the HP POD 40c NA and the associated
electrical supply system for operation and maintenance. The individual or organization that completes the
arc flash assessment must also create and provide all required labeling for all electrical panels on the HP
POD 40c NA.
Removal and replacement procedures

Fire detection and suppression
The fire detection and suppression system is a "Manufacturer Designed" system specifically for this HP
product, in compliance with national standards.
The HP standard suppression system, supplied as an optional component for the HP POD 40c NA, includes
a Novec 1230 clean agent system. However, if the customer or local AHJ requires specific modifications or
a replacement, HP can assist in these actions at the expense of the customer.
HP does not certify that the fire detection and suppression system that is installed in the HP POD 40c NA
meets all local and jurisdictional requirements. The customer is responsible for the following actions as
related to the fire suppression system:
•
Verifying that the POD detection and suppression system meets local codes, including specific local
requirements for initial and periodic inspections
•
Arranging for and receiving all required local permits, including initial commissioning as well as
standard and repair maintenance
•
Arranging for the connection of the agent tanks, refilling of tanks, and all system testing, including
pressure tests
All general maintenance of the suppression system must be completed by an authorized technician.
•
General maintenance of the fire detection and suppression system must be completed by an authorized
technician
For more information, see the HP Performance Optimized Datacenter 40c NA Maintenance and
Service guide.
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.

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.
You need a socket wrench for installation.
IMPORTANT: HP recommends that you shut down the associated IT equipment and de-energize
the appropriate section of the power busway before attempting to remove or replace a busway
drop box. The corresponding branch circuit breaker is labeled on the busway.

Leak detection maintenance
WARNING: To reduce the risk of electric shock or damage to the equipment, use extreme
caution when removing and replacing components that involve water around the electrical
equipment. There is great risk of electrical shock when water is used near electricity.
CAUTION: If a serious leak develops, shut down the POD immediately and isolate the chilled
water cooling system from the site. Contact HP immediately to initiate a field service call. Do not
attempt to repair the chilled water cooling system. Attempting to self-repair the chilled water
cooling system during the warranty or service contract period shifts all liability to you.
IMPORTANT: HP recommends shutting down the POD after a leak is detected. For more
information, see "Power down procedure" in the user guide.
Non-isolable leak detection
A non-isolable leak is a leak from the main supply line or the return header.
To repair a non-isolable leak:
1.
Power down all IT equipment.
2.
Re-direct the leaking water away from the IT equipment.
3.
Repair the leak or contact HP if you are still within your service contract.
Isolable leak detection
An isolable leak is any type of leak that does not occur from the main supply line or the return header.
To repair an isolable leak:
1.
Inspect the zone indicated on the ECS Status Overview screen. You might need to inspect each zone
condensate drain pan to determine the exact location of the leak.
Periodic maintenance
63
2.
Power down the IT equipment in the zone where the leak is located.
3.
Determine the affected heat exchanger.
4.
Close and danger tag the supply and return valves to the affected heat exchanger.
If the heat affected exchanger cannot be identified, close all the heat exchanger supply and return
valves in the affected zone and open one supply valve at a time to determine the location of the leak.
5.
Repair the leak or contact HP if you are still within your service contract.
