Question Answer
Is water prevented from entering the
MCS 5042 unit if a pipe breaks? Yes, the MCS 5042 unit is physically separate from the server
enclosure. Therefore, there is no situation in which water can come
directly in contact with the servers. The base unit of each cooling
module acts as a condensation tray for water. These trays are
connected together, so that any water drains away at once through the
condensation drain. Also, each heat exchanger module has a leak
and condensation tray that transfers water to the bottom of the MCS
5042 unit where it flows to the building condensation return system. If
a leak occurs, the integrated leak sensor detects it and an alarm would
is issued so that action can be quickly taken.
What will happen if water stops
flowing to the MCS 5042 unit?
If you have the Automatic Door Release Kit installed and enabled, an
alarm will trigger the doors of the rack to open, allowing the servers to
be cooled by the room ambient temperature.
Can I install an MCS 5042 unit to an
existing rack in my data center?
No, the MCS 5042 unit ships with an empty HP rack. However,
Configure to Order (CTO) is available.
Can I cool two racks with one MCS
5042 unit?
Yes, the HP Expansion Rack Kit is available to install to your MCS
5042 unit. You can cool a rack on either side of the MCS 5042 unit.
Can I install an existing rack in my
data center to my MCS 5042 unit as
my secondary rack?
No, you must order the HP Expansion Rack Kit to ensure the proper fit
and functionality of the secondary rack.
Will my secondary rack have the
ability to use the Automatic Door
Release Kit?
Yes, you can install the HP Automatic Door Release Kit on your
Expansion Rack. If the Automatic Door Release function is enabled, it
automatically controls the automatic door release functionality of both
racks.
