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.

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
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.
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.
Removal and replacement procedures 15
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.
Air filter
There are 2 air filters per cooling zone, for a total of 12 filters.
Tools are not required for installation.
Removing the air filter
1. Pull the locking tabs away from the air filter to release the filter.
Removal and replacement procedures 16
2.
Pull the filter down through the frame channels to remove the filter.
Replacing the air filter
1. Angle the filter to position the top corners in the frame channels, and then push the filter up to the top of
the frame.
2. Press in the bottom corners of the filter until the locking tabs engage and the filter clicks into place.
Removal and replacement procedures 17
Busway drop box
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.
Removing the busway drop box
1. Turn the power off by opening both breakers on the busway drop box (1).
2. Disconnect the PDUs that are connected to the busway drop box (2).
3. Use a socket wrench to loosen and remove the bolt securing the busway drop box to the retaining
hardware bracket (1).
Removal and replacement procedures 18
4.
Slide the hardware bracket to the right along the busway, completely disconnecting it from the busway
drop box (2).
WARNING: Use caution when removing and replacing the busway drop box. The drop box
weighs approximately 9 kg (20 lb).
5. Rotate the busway drop box 90° so that it is perpendicular to the electrical busway, and then remove
the drop box from the electrical busway (3).
Replacing the busway drop box
WARNING: Use caution when removing and replacing the busway drop box. The drop box
