Remote Management Feature
Server management is concentrated in the ExpressScope. The ExpressScope and
associated circuitry are powered from a 5V DC standby voltage, which remains active
when system power is switched off, but the ac power source is still on and connected.
The ExpressScope supports Dianascope, which allows remote server management
through the network. Events monitored by the manager system include over-
temperature and over-voltage conditions, fan failure, or chassis intrusion.
Information on Dianascope may be found in the ExpressBuilder DVD-ROM.
One major function of the ExpressScope is to autonomously monitor system
management events, and log their occurrence in the nonvolatile System Event Log
(SEL). The events being monitored include overtemperature and overvoltage
conditions, fan failure, or chassis intrusion. To enable accurate monitoring, the
ExpressScope maintains the nonvolatile Sensor Data Records (SDRs), from which
sensor information can be retrieved. The ExpressScope provides an ISA host interface
to SCR sensor information, so that software running on the server can poll and retrieve
the server's current status.
The ExpressScope performs the following:
■
Monitors server board temperature and voltage*
■
Monitors processor presence and controls Fault Resilient Boot (FRB)
■
Detects and indicates baseboard fan failure*
■
Manages the SEL interface
■
Manages the SDR Repository interface
■
Monitors the SDR/SEL timestamp clock
■
Monitors the system management watchdog timer
■
Monitors the periodic SMI timer
■
Monitors the event receiver
■
Controls secure mode, including video blanking, diskette write-protect monitoring,
and front panel lock/unlock initiation
■
Controls Wake On LAN via Magic Packet support.
■
Monitors the hard disk drives.
* NEC ESMPRO also supports these features.
