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.
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.
Removal and replacement procedures 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.
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.
