General Description 2-21
Remote Management Card (RMC)
Server management is concentrated in the optional Remote Management Card (RMC). The RMC
and associated circuitry are powered from a 5Vdc standby voltage, which remains active when
system power is switched off, but the ac power source is still on and connected.
The RMC supports the NEC DianaScope, 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 NEC DianaScope may be found in the NEC EXPRESSBUILDER CD-ROM.
One major function of the RMC 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 RMC maintains the nonvolatile Sensor Data Records (SDRs), from which sensor
information can be retrieved. The RMC 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 RMC 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 teimestamp 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.
*Also, NEC ESMPRO supports these features.
