Overview Introduction The HP Modular Cooling System G2 has a management module with a web interface that analyzes, queries, and manages various measurements and warning and alarm messages from the MCS G2 unit. The management module analyzes measurements provided by the cooling unit, generates any necessary warning or alarm messages, and sends the messages to the web interface.
Web interface Using the web interface The web interface is divided into three frames: • • Top frame—Contains a Sign Out hyperlink and the Home, Logs, Setup, System Name, and Help tabs. o Sign Out⎯Enables you to log out of the web interface. o Home⎯Displays the menu options for viewing general status information. For more information, see "Home tab (on page 8)." o Logs⎯Displays the menu options for data logs. For more information, see "Logs tab (on page 19).
• Main frame—Contains the various web interface screens based on the menu option selected in the left navigation frame. Active Alarms and Legend display panel Each tab in the web interface contains an Active Alarms and Legend display panel. When the MCS unit experiences a critical, warning, normal, unknown, or informational event, the icon corresponding to the event appears in the Active Alarms display panel.
where hostname is the IP address of the management module and port number is the port number if using a port other than the default 80 for http and 443 for https. The login screen appears. 3. Log in through the web browser. Logging in through the web interface 1. Enter the user name in the User Name field. The default user name is Admin. 2. Enter the password in the Password field. The default password is Admin. NOTE: Passwords are case-sensitive. 3. Click Sign In.

1. Verify water flow matches specifications required for heat load. 2. Verify whether the water temperature is above the expected range. 3. Adjust the temperature assigned in the web interface Intake Temp tab (on page 22) Warning Temperature Threshold field. 4. Contact your building supervisor.
Solution: 1. Verify water supply and that the MCS unit is receiving water. 2. Verify that the High Temperature Emergency Door Opening Threshold is not less than 5°C (41°F) above or more than 20°C (68°F) above the Server Intake Temperature Set Point, or that it is not below the Water Flow Loss Emergency Door Opening Temperature Threshold. 3.
2. If no leaks are found, adjust the temperature in the Excessive Moisture: Condensation Pump Running Time Warning Threshold field. IMPORTANT: Use caution when entering temperatures in the Condensation Pump Threshold fields. Be sure to determine the proper default settings to prevent false alarms, without masking problems with the MCS. Default settings will vary, depending on the humidity level of your data center and the heat load generated by the equipment in the MCS.

Upgrading the firmware Upgrading the HP Modular Cooling System firmware The MCS unit must have the latest firmware to work properly. To upgrade the firmware: 1. Access the HP website (http://www.hp.com). 2. Click Software & Driver Downloads. 3. Ensure that the Download drivers and software (and firmware) option is selected. 4. Type Modular Cooling System in the product name field, and then click Search. If any firmware upgrades are available, they will display on this page.
Cooling performance parameter settings 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 cooling needs of the rack-mounted components. The temperature of the server intake air is controlled by varying the opening percentage of the water valve inside the MCS unit.
Parameter Function Water Flow Loss Emergency Door Opening Temperature Threshold Used to open the MCS doors when the temperature threshold is exceeded and water loss is detected This value cannot be lower than 5°C (41°F) above or more than 20°C (68°F) above the Server Intake Temperature Set Point.
IMPORTANT: Temperature Control Manual mode is for service and troubleshooting only and is not to be used in a production environment.
Server intake temperature Server exhaust temperature Top 24.5°C (76.1°F) 38.8°C (101.8°F) Middle 24.8°C (76.6°F) 39.1°C (102.4°F) Bottom 25.1°C (77.2°F) 40.3°C (104.5°F) Average 24.8°C (76.6°F) 39.4°C (102.9°F) Adjusting the cooling air flow provided by the MCS unit To adjust the cooling air flow provided by the MCS unit while in Temperature Control Auto mode: 1. Click the Setup tab (on page 21). 2. Click the Advanced tab (on page 28). 3. Enter a Delta Temperature For Minimum Fan Speed.
• o Delta Temperature For Minimum Fan Speed o Delta Temperature For Maximum Fan Speed o Cooling Liquid Heat Capacity Temperature Control Manual mode—Used to verify the water flow rate after the cold water supply has been connected. When the water flow rate has been validated, use the Auto mode setting.
Systems Insight Manager integration 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.
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.
Configuring the management module to send traps to HP SIM 1. Add the HP SIM server as an SNMP trap recipient on the Trap Receivers tab (on page 34). 2. Configure the management module to send alert notifications to HP SIM.
Security considerations 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.
Frequently asked questions Frequently asked questions Question Answer How many user sessions are supported at one time? Only one user session is supported at a time. Sessions can be terminated if a second session is initiated or if a console session timeout occurs. How many Admin sessions are supported at one time? Only one Admin session is supported at a time. Sessions can be terminated if a second session is initiated or if a console session time-out occurs.
Question Answer Is there a confirmation that my system No, there is no confirmation that the system is being restarted. is being restarted after I select the Restore to Factory Defaults or Restart buttons, or after I restore a configuration? Why is the web browser not responding when I enter the management module IP address? • SSL might be enabled. Enter https://hostname[:port number] where hostname is the IP address of the management module and port number is the port you assign for SSL.
