Afterwards, the ^M does not return when the enter key is pressed. The issue returns if the MP
is reset through the modem.
Server Management Overview
Server management consists of four basic functional groups:
• Chassis management
• Chassis logging
• Console and session redirection
• Service access
Chassis Management
Chassis management consists of control and sensing the state of the server subsystems:
• Control and sensing of bulk power
• Control and sensing of DC-to-DC converters
• Control and sensing of fans
• Control of the front panel LEDs
• Sensing temperature
• Sensing of the power switch
• Sensing chassis intrusion
• Reading FRU PROMS
Chassis Logging
Chassis logging consists of maintaining logs of chassis codes:
• Boot codes
• Activity codes
• Error codes
Console and Session Redirection
Console and session redirection enables the console and session terminals to be connected over
RS-232, a modem, or a LAN connection (web console).
Service Access
Service access enables access to and control of server state. Service access is secured by a password.
Service access functions include:
• Access to chassis logs
• Configuration of partitions
• Control for online addition and replacement
• Access to the virtual front panel
• Transfer of control and reset
Server Management Behavior
This section describes how the system responds to over-temperature situations, how the firmware
controls and monitors fans, and how it controls power to the server.
Thermal Monitoring
The manageability firmware is responsible for monitoring the ambient temperature in the server
and taking appropriate action if this temperature becomes too high. To this end, the ambient
