Rittal Liquid Cooling Package
Solid front door (glass/sheet steel) in conjunction
with a solid rear door (glass/sheet steel) of the
server rack
If the need arises, both the front and the rear door are
automatically opened. The air flows unhindered into
the interior of the enclosure, circulates around the in-
stalled equipment and exits the system via the open
rear door of the enclosure. It is important to ensure
that the LCP fans are switched off, otherwise hot air
will be blasted in front of the 482.6 mm (19") level in
the event of emergency cooling.
If this variant is used, whether for fire extinguishing
purposes or for emergency cooling purposes, the in-
stallation room must be air-conditioned (ASHRAE con-
ditions, 22 °C, 50% rel. humidity).
If this method is used for emergency cooling, even
higher heat losses in the server rack can be dissipat-
ed.
With this method, the escape route is blocked at both
the front and back of the server rack. Unauthorised
access is possible through the open front and rear
doors. The separate partition between the cooling
system and the rack is eliminated.
If the system used is equipped with an automatic door
opening feature, the latter must be activated via the
LCP software.

Extended options by connecting the
Liquid Cooling Package to a network
By connecting the Liquid Cooling Package control
unit (CMC III PU) to a network, you are able to call up
various measurements and warning or alarm messag-
es. These may then be further processed (e.g. via a
Web browser, SNMP, etc.). Furthermore, various val-
ues can be set via the network and then sent to the
control unit.
In the Liquid Cooling Package, the network connec-
tion for the CMC III PU is routed to a jack in the upper
rear area of the device. To connect to a network, this
jack should be connected to a free jack on a network
access using a Category 5 patch cable. The Liquid
Cooling Package is preset in the factory to the IP ad-
dress 192.168.0.190 (see section 8.2 "HTTP connec-
tion").

Layout of screen pages
After logging on to the Liquid Cooling Package (see
section 8.2.1 "Making the connection"), the Web inter-
face for operating the device is displayed. In princi-
ple, the screen is divided into four different sections:
1. Top section: Display general information about the
device, change the password and log off the cur-
rent user (see section 9.4.7 "Logging off and
changing the password").
2. Left-hand section: Select the overall system or re-
spective component for which information is dis-
played in the right-hand section of the screen (see
section 9.4.2 "Selection tree in left-hand section").
3. Right-hand section (main section): Display four in-
dex tabs (see section 9.4.3 "Index tabs in the
right-hand section") with input options for all set-
tings.
4. Bottom section: Display messages (see
section 9.4.4 "Message display").
