Overview Introduction The HP mc-Series 5042 Rack has a management module with a web interface that analyzes, queries, and manages various measurements and warning and alarm messages from the MCS 5042 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 OutEnables you to log out of the web interface. o HomeDisplays the menu options for viewing general status information. For more information, see "Home tab (on page 8)." o LogsDisplays the menu options for data logs. For more information, see "Logs tab (on page 19).
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. The alarm descriptions appear in the Alarms menu, as well as in the Alarm History menu (on page 20).
For instructions on changing the password, see "Accounts menu (on page 35)." Only one Admin session and one User session are supported at a time. Sessions can be terminated if a second session is initiated (after successful login) or if a console session timeout occurs. In both situations, the existing session is terminated and the login screen appears. Admin session logins, logouts, and terminations are recorded in the Event Log menu (on page 21).
Overview menu To display the Overview screen, in the left navigation frame, click Overview. This screen displays graphic meters for temperature and cooling system parameters.
Alarms menu Click Alarms in the left navigation frame to display the Alarms screen. The active alarms are listed by the date and time at which the alarm most recently occurred. The active alarm is removed from the Alarms screen when cleared but is recorded in the Alarm Log.
2. Reinstall the same fan unit. If the warning message does not clear after the module is reseated, replace the fan unit with a CSR part. For more information on CSR parts, see "Replaceable parts and maintenance and service information (on page 51)."

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 5042 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 5042 unit.
Parameter Function Low Temperature Threshold Used to issue a warning if the low temperature threshold temperature is exceeded Water Flow Loss Emergency Door Opening Temperature Threshold Used to open the HP mc-Series 5042 Rack 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 provided by the MCS unit The management module constantly compares the server intake temperature to the range calculated from the Server Intake Temperature Set Point. • If the server intake temperature is above the Server Intake Temperature Set Point, the opening percentage of the water valve increases to allow more cold water to enter the heat exchanger unit.
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.
#------------------------------------------------------#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.
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.
