Question Answer

Does the air flow within the MCS

unit produce static electricity?

Very low humidity levels in the chilled air may produce static

electricity. However, static electricity is not a problem if the MCS

unit is operated at the specified settings located in the HP Site

Preparation Guide and the Environmental specifications listed in this

document.

Why do I get an extra line feed sent

from 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 unit if a pipe breaks?

Yes, the MCS 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

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 unit?

If you have the Automatic Door Release Kit, an alarm will trigger the

doors of the rack to open, allowing the servers to be cooled by the

room ambient.

Can I install an MCS unit to an

existing rack in my data center?

No, the MCS unit ships with an empty HP 10000 G2 rack.

However, Configure to Order (CTO) is available.
