System Overview 1-11
System Board Management Controller (BMC)
Server management is concentrated in the System Board Management
Controller (BMC). The BMC and associated circuitry are powered from a
5Vdc standby voltage, which remains active when system power is
switched off.
The BMC supports the Emergency Management Port (EMP) Console
which allows remote server management via a modem or direct
connection to a manager system. Events monitored by the manager
system include over-temperature and over-voltage conditions, fan
failure, or chassis intrusion.
Information on the Emergency Management Port (EMP) Console may be
found in Appendix C of this User’s Guide.
System Security
To help prevent unauthorized entry or use of the system, the system
includes a physical padlock loop and Server Management software that
monitors the system intrusion switch.
Security with Mechanical Locks and Monitoring
Activate the side cover intrusion alarm switch. When the side door is
opened, the switch transmits an alarm signal to the system board,
where server management software processes the signal.
