HP POD 20c racks

The HP POD 20c contains a total of ten IT racks.

CAUTION: If any racks contain empty RU space, use the HP POD 20c filler panels to maintain the efficiency of the HP POD 20c 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.

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.
