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 fil er 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 fol ow the clear aisle
distance calculations. The following figure shows how to calculate this distance.
The maximum rack face-to-cold aisle wal distance is 39.5 inches. In the figure, X represents any protrusion
into the cold aisle starting from the rack face of the instal ed IT component (for example, the bezel). Y
represents cold aisle clearance. The cold aisle clearance dictates the maximum depth (D) of any instal ed 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.
