Air routing
In order to ensure adequate cooling in the server enclo-
sure, it is important to ensure that the hot air from the
fans of the installed equipment is routed directly via the
LCP Hybrid and is prevented from accumulating inside
the server enclosure.
Targeted air routing in the server enclosure has a major
effect on the heat loss to be dissipated. It is therefore im-
portant to assemble the device and the additional in-
stalled equipment in the server enclosure as described
in section 5.2 "Assembly procedure".
In order to ensure targeted air routing in the system, the
server enclosure should be divided vertically into warm
air and cold air sections. The division is accomplished in
the rear section of the server assembly to the left and
right of the 482.6 mm (19") level using air baffle plates,
which, depending on the enclosure width and the num-
ber of server enclosures to be cooled, can be ordered as
accessories (see section 12 "Accessories").
This prevents the hot air from flowing back at the sides
adjacent to the server installations and forming hot spots
(fig. 3).

If the air baffle plates remain in the front section of the
server enclosure, hot spots may form in the server en-
closure (fig. 4).

Cooled air
If devices which require sideways air throughput are built
into the server enclosure (e.g. switches, router, etc.),
these may be cooled via targeted repositioning of the air
baffle plates.

Note:
When using devices which require sideways
air throughput, repositioning of the air baffle
plates means that the entire width of the heat
exchanger is not used to optimum effect.
