Removal and replacement procedures
Safety considerations
The HP POD 40c G2 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 G2 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 G2.
IMPORTANT: All plumbing to and from the HP POD 40c G2 must be completed by a licensed
plumber.
IMPORTANT: All wiring in and around the HP POD 40c G2 must be completed by a licensed
electrician.
Operator safety
The HP POD 40c G2 provides service access areas for periodic maintenance and service and is only to be
used by owner-authorized personnel specifically trained in the maintenance and service of the HP POD 40c
G2.
The HP POD 40c G2 is not a habitable structure suitable for long term personnel occupancy.
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 G2 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 G2.
WARNING: To avoid the risk of personal injury or damage to the equipment, do not insert
anything inside the electrical busways except the approved HP busway drop boxes.
The customer is responsible for completing any Environmental Health and Safety (EHS) evaluation of the HP
POD 40c G2 or any attached structural component purchased through HP. The customer must complete an
arc flash assessment of the HP POD 40c G2 and the associated electrical supply system for operation,
maintenance, and so on.
Fire detection and suppression
The fire suppression system, supplied as an optional component of the HP POD 40c G2, is a "Manufacturer
Designed" system specifically for this HP product, in compliance with national standards.

Removal and replacement procedures 16
The HP standard suppression system 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 suppression system installed in the HP POD 40c G2 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 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.
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 17
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 18
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 19
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
weighs approximately 9 kg (20 lb).
1. Place the silver drop box bracket onto the electrical busway where you want to replace the busway
drop box (1).
2. Note the required rotation indicated on the drop box, insert the drop box into the drop box bracket on
the electrical busway, and then rotate the drop box 90° until it locks into place (2).
CAUTION: To prevent damage to the drop box and ensure that the drop box engages properly,
be sure that the drop box is completely flush to the busway. If a drop box is damaged during
installation, do not attempt to re-engage or repair the drop box.
3. Slide the hardware bracket to the left along the busway until it connects to the drop box (3).

Removal and replacement procedures 20
4. Secure the busway drop box to the retaining hardware bracket by using a socket wrench to insert and
tighten a bolt (4).
5. Connect the PDUs to the busway drop box (1).
6. Turn the power on by closing both breakers on the busway drop box (2).
Differential pressure sensor
The differential pressure sensors are located in the cold aisle.
You need a Phillips-head screwdriver for installation.
