Introduction
The HP Modular Cooling System has a management module with a web interface that analyzes, queries,
and manages various measurements, and warning and alarm messages from the MCS unit.
The management module analyzes measurements provided by each cooling module, generates any
necessary warning or alarm messages, and sends them to the web interface. When a new warning or
alarm occurs, the warning and alarm messages (on page 10) appear on the operator display, as well as
on the web interface Alarms menu, Alarm History menu, and an SNMP trap is sent to up to four trap
receivers ("Trap Receivers tab" on page 35). An alarm relay is also activated (if enabled), and an alarm
is signaled acoustically by the MCS unit internal beeper (if enabled in the appropriate web interface
menu). For more information on connecting an alarm device to the management module alarm relay, see
the HP Modular Cooling System User Guide.
The web interface (on page 6) displays various measurements and warning and alarm messages (on
page 10) from the management module. Also, various system values can be set through the web interface
and sent to the management module. The MCS unit can be monitored with HP SIM. For more information,
see "HP Systems Insight Manager integration."

Browser security alert
Secure browsing requires the use of SSL. SSL is a protocol layer that lies between HTTP and TCP that
provides secure communication between a server and a client and is designed to provide privacy and
message integrity. SSL is commonly used in web-based transactions to authenticate the web server, which
indisputably identifies the server to the browser. SSL also provides an encrypted channel of
communication between the server and the browser. The encrypted channel ensures integrity of the data
between the web server and the browser, so that data can neither be viewed nor modified while in
transit. The management module uses a system generated and unique key.
An integral part of SSL is a security certificate, which identifies the management module. If your browser
displays a security alert when browsing to the management module, it can be for one of several reasons:
•
The certificate is untrusted, meaning it was signed by a certifying authority that is unknown to your
browser.
•
The certificate has expired or is not yet valid. This condition can occur if you issue your own
certificate and it has expired.
•
The name on the certificate does not match the name of the site in the browser address field.
For more information about security considerations, see "Security considerations overview (on page 52)."

a. Click No at the Security Alert window.
b. Obtain an exported certificate file from the administrator.
NOTE: If using Internet Explorer, you can manually import the file into the browser by clicking
Tools>Internet Options>Content>Certificates>Import.

Cooling performance parameter settings
In this section
Cooling performance parameter settings overview ..................................................................................... 44
Cooling performance parameter settings overview
The MCS unit has several cooling performance parameter settings. These settings control the fan speed
and water flow to meet the rack-mounted component's cooling needs.
The temperature of the server intake air is constantly controlled by the opening and closing of the solenoid
actuated water valve inside the MCS unit. When the server intake air temperature goes above the Server
Intake Temperature Set Point the water valve opens. When the server intake air temperature falls below
the Server Intake Temperature Set Point minus the Hysteresis Value, the water valve closes.
The speed of the fan units is constantly controlled through the control system using the server intake and
server exhaust temperatures.

Delta temperature (Server Intake Temp/Server Exhaust Temp)
Delta temperature is calculated from the temperature difference between the server intake temperature
and server exhaust temperature. The server intake temperature, or cold air, is the air coming from the heat
exchanger units and pushed through the fan units. The server exhaust temperature, or hot air, is the air
coming from the fan units and being pushed through the heat exchanger units.

Cooling air flow supplied by the MCS unit
Delta temperature is used to determine and control the speed of the rotating fans.
This example shows the fan speed control function when the minimum fan speed is 35%, delta
temperature for minimum fan speed is 5°C (9°F), the delta temperature for 100% fan speed is 20°C
(36°F). In this case, the delta control temperature is 18°C (32°F) and will cause the fans to run at 94%
speed.

•
If the server intake temperature is above the Server Intake Temperature Set Point, the water valve
opens (if not already opened) and cold water enters the heat exchanger units.
•
If the server intake temperature is below or equal to the Server Intake Temperature Set Point minus
the Hysteresis value, the water valve closes (if not already closed).
•
If the server intake temperature is between the Hysteresis value, the water valve remains unchanged
from its previous state.

Systems Insight Manager overview
Use HP Systems Insight Manager to:
•
Discover management modules. As part of the discovery process, HP SIM can detect an installed
management module. The web interface for the discovered module can be launched from the HP
SIM Servers Links tab.
•
Receive SNMP traps from the management module. The management module can send event-based
traps to HP SIM that include a URL in the trap. This functionality enables administrators to easily
launch the web interface of the management module in context. For example, if the management
module detects an alarm condition, the management module can send a trap to HP SIM with an
attached hyperlink that routes users directly to the web interface for the attached management
module.
•
Conveniently launch the management module web interface from within HP SIM.
o
Tools menu—You can add a link to the web interface on the HP SIM Tools menu using a tools
definition file.
o
Servers Links tab—The web interface can be launched from the HP SIM Servers Links tab.
o
Event-based trap—A URL is included in each trap to link directly from HP SIM to the web
interface for the specific device for which the trap was sent.
The management module can be configured to send alert traps to Systems Insight Manager, and other
SNMP management applications.
To send event alert traps to Systems Insight Manager:
1.
Configure HP SIM to receive traps ("Configuring HP SIM to receive traps" on page 50).
2.
Configure the management module to send traps to HP SIM ("Configuring the management module
to send traps to HP SIM" on page 51).
Discovering the management module
HP SIM automatically detects management modules as part of the device discovery process. If detected, a
hyperlink is included on the HP SIM Links page for the HP Modular Cooling System on which the
management module is installed. The management module should be installed and running before
attempting discovery through HP SIM.
If a link to the HP Modular Cooling System on which the management module is installed does not appear
on the device home page in Systems Insight Manager:
Systems Insight Manager integration 49
1.
Locate the additionalwsdisc.props file in the CONFIG directory in the Systems Insight Manager
install directory. By default, Systems Insight Manager is installed in the C:\Program Files\HP\System
Insight Manager directory.
2.
Create a management module entry in the additionalwsdisc.props file. For more information on
editing the additionalwsdisc.props file, see the additionalwsdisc.txt file located in the same directory.
Example: The additionalwsdisc.props file with a management module entry
#------------------------------------------------------#Additional Web Server Discover Properties
#------------------------------------------------------#NOTE: See "AdditionalWsDisc_README.txt" for a description of entries in
this file and how to add or remove additional web server ports for discovery
and identification.
#------------------------------------------------------The following are actual web server ports enabled by default.
#To remove them from the discovery process, comment out the line with a '#'
or remove it. You will need to restart the HP SIM service for the changes to
take effect. In addition, you will need to run the Device Identification
task to find any new ports that were defined.
#------------------------------------------------------#411=Director Agent,,true,false,,http
#3201=Compaq TaskSmart,,true,false,,https
#8008=Default Home Page,,true,false,,http
#1311=Server Administrator,,true,false,,https
#1234=HP Modular Cooling System,,true,false,,https
The last entry allows System Insight Manager to detect management module installations that are running
on port 1234 and using HTTPS.
Configuring HP SIM to receive traps
Before HP SIM can receive traps, the correct MIB file (cpqwcrm.mib) must be compiled into HP SIM.
To register the MIB:
1.
Copy the .MIB file from the MCS documentation CD MIBs folder to the HP\Systems Insight
Manager\mibs folder.
2.
From the HP\Systems Insight Manager\mibs folder, run mcompile cpqwcrm.mib from the
command line to compile the new .MIB file. A new file named cpqwcrm.cfg is created.
3.
Register the new .MIB file by entering mxmib -a cpqwcrm.cfg from the HP\Systems Insight
Manager\mibs command line.
4.
Enter HP\Systems Insight Manager\mibs>mxmib at the command line, and verify that the
new .MIB file is listed.
NOTE: For more information on uploading and registering a MIB in HP SIM, refer to the HP
Systems Insight Manager Technical Reference Guide located on the HP Management CD.

Security considerations overview.............................................................................................................. 52
Security considerations overview
The management module implements strict security for two important reasons:
•
The module manages devices that have the potential to perform operations that are sensitive and
destructive.
•
The management module has browser accessibility.
To better ensure the security of the management module and the devices it manages, consider the
following topics in accordance with your organization's security policies and the environment in which the
module will operate.
•
Remote access to the management module requires a user account. Logging in requires the use of a
user name and password, which should be kept properly secured.
•
Each account can be given different access levels, providing different capabilities. Ensure that the
appropriate access level is granted to users.
•
Browsing to the management module can be done using SSL, which encrypts the data between the
browser and management module. The module is supported by a 128-bit encryption level. SSL also
provides authentication of the management module by means of its digital certificate. Securely
importing this certificate must be done to ensure the identification of the management module.
