Question

Answer

Why do I get an extra line feed sent
from Microsoft® Windows® when I

access the serial interface using an
HP serial console switch?

Enter these commands while logged in as Admin on the HP serial
console switch console port (where port x is the port connected to the
MCS management module):

port x set out lf=strip

port x set flow=Xonxof

Is water prevented from entering the
MCS-100 unit if a pipe breaks?

Yes, the MCS-100 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-100 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-100 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-100 unit to an

existing rack in my data center?

No, the MCS-100 unit ships with an empty HP rack. However,

Configure to Order (CTO) is available.

Can I cool two racks with one

MCS-100 unit?

Yes, the HP Expansion Rack Kit is available to install to your MCS-100
unit. You can cool a rack on either side of the MCS-100 unit.

Can I install an existing rack in my

data center to my MCS-100 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.
