CAUTION:
If any racks contain empty RU space, use the HP POD 240e NA filler panels to
maintain the efficiency of the HP POD 240e NA thermal system. Filler panels are available from
HP in 10-pack quantities (part number AQ682A) and 100-pack quantities (part number
AS993A).

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
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
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.
Grounding requirements
The HP POD 240e NA structure and internal components are all bonded together. A common grounding
electrode conductor connection point is provided on the utility end of the IT sections.
WARNING:
To avoid the risk of personal injury or electric shock, the HP POD 240e NA must be
properly grounded (earthed) in accordance with national, regional, and local regulations.
CAUTION:
Remove paint from all grounding surfaces. Failure to do so results in an ineffective
ground.
