Overview About this document This document outlines the site requirements for an HP Performance Optimized Datacenter (POD) 240a. The customer must provide a qualified architectural or consulting engineering team to generate site-specific documents for each HP POD 240a installation, including final site drawings. The customer's site installation design must comply with all local and national regulations, ordinances, codes, and the specifications listed in this document.
Capacities Capacity limitations The capacity limitations of the HP Performance Optimized Datacenter (POD) 240a includes two main categories: electrical power capacity and mechanical cooling capacity. Both of these categories are interdependent, and you must consider them in conjunction with the overall customer requirements. The limiting capacity (electrical or mechanical cooling) is the overall limiting design factor and is used by HP to develop the POD solution for our customer.
Overall system capacity Depending on how you decide to approach redundancy determines the maximum design power that will be capable. The HP POD 240a is limited by cooling to N = 1347 kW / N+0 = 674 kW even though Critical IT Load can reach 2N levels of redundancy.
System cooling HVAC system HVAC systems are designed for conditioning the air in a portable, containerized computer room. The systems are installed directly on top of the HP POD 240a for conditioning the air inside. HVAC systems are available with air conditioners mounted on a structural steel cradle. The cradle serves as a lifting platform and as an interface to the container roof. Each DX unit is equipped with louvered dampers for controlling the airflow through the unit.
• Verify the POD suppression system meets local codes, including specific local requirements for initial and periodic inspections. • Arrange for and receive all required local permits, including initial commissioning. • Arrange 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 SimplexGrinnell technician.
Site assessment Completing a site assessment HP requires a detailed site assessment prior to planning and preparing the customer site location for the HP POD 240a. Consult with HP to schedule a site assessment.

Site requirements Site pad The structural design of the HP POD 240a site pad is based on specific weight load locations, accounting for the HP POD 240a structural footing and supported IT infrastructure. The site pad must be level with less than +/-0.5 degrees differential from extreme to extreme. Shimming is allowed when shims are used directly under the HP POD 240a load pads, and are placed in increments across the length of the HP POD 240a, ensuring the HP POD 240a is level.

End 1 view clearances shown Utilities Consider proximity to required utilities, such as power, water, and network connections. While required utilities can be brought to nearly any selected site, there is a potential for increased costs and decreased efficiency when the HP POD 240a is located further from the utility source. For utility clearance information, see "HP POD 240a dimensions and required clearances." Water supply The HP POD 240a requires supply water for the humidifier.
In addition to the previous requirements, follow these guidelines: • Do not treat the water with softeners, because softeners might produce foam which affects the operation of the unit. • Do not use well water, industrial water, water from cooling circuits, or water contaminated by any chemicals or bacteria. • Do not add disinfectants or anti-corrosive compounds to the water, which are potential irritants. For additional dimensions, see the HP Site Preparation Drawing Package (on page 10).
Facility connections The HP POD 240a is designed to function as a standalone unit, but it can be connected to existing facility systems with additional engineering and costs.
Environmental considerations Environmental risks • Avoid placing the HP POD 240a directly along a drainage path or in an area prone to flooding. • Verify that the HP POD 240a is properly grounded in accordance with NFPA 70 in accordance with NEC (NA) and IEC (EMEA and APJ). Cold weather The HP POD 240a requires a water supply and several water drains. Extreme cold weather might cause damage to the supply and drain lines.
WARNING: To avoid the risk of personal injury or electric shock, the HP POD 240a must be properly grounded, and each of the individual sections must be bonded together per NFPA 70 in accordance with NEC (NA) and IEC (EMEA and APJ). CAUTION: You must remove any painted surface from all grounding surfaces. Failure to do so results in an ineffective ground. • Grounding and bonding of the HP POD 240a must comply with Article 250 of the NFPA 70 in accordance with NEC (NA) and IEC (EMEA and APJ).

Preparing for delivery and assembly Shipping considerations • The HP POD 240a is packaged for shipping such that exposure to weather does not result in damage to the components. • The HP POD 240a is shipped on air-ride trailers to avoid vibrations during shipment. • The HP POD 240a components are shipped based on the assembly plan and available space at the customer site. • Depending on the site location, additional restrictions and permits might be required, which can affect the delivery time line.
Arc Flash safety The customer must complete an Arc Flash assessment of the HP POD 240a and the associated electrical supply system for operation, maintenance, and so on. Temporary lighting and power Proper temporary lighting and power must be installed and maintained in all construction work areas. When using temporary lighting: • Label panels and breakers that are used for temporary lighting and power.
• The required PPE and head protection (on page 21) for all personnel is available.
Appendix A: HP Site Assessment HP POD 240a site assessment checklist Survey the readiness of a proposed customer site for the HP POD 240a. This service includes inspection of the site for: • Accessibility of machinery for the transportation and installation of the HP POD 240a • Assessment of the suitability of the site infrastructure for installing the HP POD 240a and for supporting infrastructure preparation and serviceability requirements. HP responsibilities: Item Description 1.
Item Description 8. Clearances Inspect the proposed installation site to confirm clearance requirements for installation and serviceability as per the HP POD 240a specifications. Necessary clearances will be determined, in part, based on the specific installation plans and infrastructure design. Location, orientation and planned utilization can all affect the necessary clearances. Future planning for the space around the installation site will also be taken into consideration.
Item Description 14. Recommendation s Following HP installation site visit, analyze the data collected and prepare a report of findings. HP must identify potential obstacles to installation and recommendations for any additional testing or changes to the installation plan. Sign-off Customer responsibilities: Item Description Sign-off 1. Point of contact Provide HP with the name and telephone number of the designated point of contact for the purposes of this information Service. 2.

This assistance will typically take the form of preparation of a letter of invitation. In some cases, a formal request must be made by the local company for whom the work is taking place.
Item Description 13 Verify all utilities, overhead and underground, are identified to maintain required clearance. Verify adequate clearance around the HP POD 240a for door operation, installation, and maintenance equipment. Verify the site location and site pads are marked for the transformer, main external switchboard, generators, and powerhouses. Verify the site has provisions for proper grounding. Verify the site location includes a grounding system.
