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.
When a new warning or alarm occurs, the following events occur:
• The warning and alarm messages (on page 10) appear on the operator display and the web interface
Alarms menu and Alarm History menu (on page 20).
• An SNMP trap is sent to up to four trap receivers ("Trap Receivers tab" on page 34).
• An alarm relay is also activated (if enabled).
• An audible alarm is signaled by the MCS 5042 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
mc-Series 5042 Rack User Guide.
Various system values can be set through the web interface and sent to the management module. You can
monitor the MCS 5042 unit with HP SIM. For more information, see "Systems Insight Manager integration
(on page 46)."

Each tab in the web interface contains an Active Alarms and Legend display panel.
Web interface 6
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).
In the Legend display panel, the descriptions for following five icons display:
Icon Reference Description
Critical Appears when a parameter is not operating at a normal condition and must be
Warning Appears when a parameter is not operating at a normal condition and must be
investigated immediately
investigated
Normal Appears when all parameters are operating at a normal condition
Unknown Appears when a parameter is operating at an unknown condition
Information Displays information about a parameter
Accessing the management module through the web interface
1. Launch a supported browser. The browser window appears.
2. In the Address field (Microsoft® Internet Explorer) or the Location field (Mozilla), enter one of the
following:
http://hostname[:port number]
-orhttps://hostname[:port number] (if SSL is enabled)
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.

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). The console session timeout length can be enabled,
disabled, or modified in the Remote Access tab (on page 24). The default is 30 minutes.
