Rittal Liquid Cooling Package Plus
e.g. brush strips.
Whilst the system is in operation, both the front and the rear doors should be
kept completely shut.
In order to ensure the targeted air routing in the system, the server enclosure is
divided into warm air and cold air sections. The division is accomplished in the
front section of the server assembly to the left and right of the 482.6 mm (19")
level through foam strips, which, depending on the enclosure width and the
number of server enclosures to be cooled, can be ordered as an accessory
(see Chapter 13, "Accessories").
If devices which require sideways air throughput are built into the server enclo-
sure (e.g. switches, router, etc.), these may be cooled through targeted place-
ment of the foam strips.
Note:
However, the system does not need to be completely airtight. This is not ne-
cessary due to the high, coordinated air throughput of the server fans and
LCP Plus fans.
In fact, a small amount of ambient air is desirable, since this can prevent the
cooling air from becoming too dry.
Note:
The 482.6 mm (19") level must likewise be completely sealed. This is already
the case in a fully equipped server enclosure. If the server enclosure is par-
tially equipped, the open height units (U) of the 482.6 mm (19") level must
be sealed with blanking plates, which are available from the Rittal accessory
range (see Chapter 13, "Accessories").
As more devices are installed in the server enclosure, it becomes even more
important to follow this specification.
