MP-to-MP link. All external connections to the MP must be to the primart MP in slot 1. The

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 CRU 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 allows the console and session terminals to be connected over
RS-232, a modem, or a LAN connection (Web console).
Service Access
Service access allows 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.
