Chapter 1 General Description

4.3.3 Power Management

Failure of commercial power supply is one of major causes of system stop.
In addition to power failure and temporary blackout, voltage reduction, electrical overload power distribution,
failure in power facility, etc. may cause system failure.
Uninterruptible Power System (UPS) automatically supplies power from the battery when voltage of
commercial power supply starts dropping because of power failure or temporary blackout and thus prevents
the system from being stopped. System administrator can save files and perform necessary processes while
power is supplied. UPS also reduces the variation of voltage and electric current and extends lifespan of the
power device, resulting in contributing to increasing the mean time between failures (MTBF). This can also
achieve automatic and unattended operation by schedule.

4.3.4 Network Management

By using NEC ESMPRO Manager and NEC ESMPRO Agent, error packet of LAN connected to the server can
be monitored. By using separately sold WebSAM/Netvisor of Windows version, the entire network can be
managed.

4.3.5 Remote Management

By using EXPRESSSCOPE Engine SP3 and NEC ESMPRO Manager provided with the server as standard,
the remote monitoring and management of the server through LAN or WAN can be performed.
EXPRESSSCOPE Engine SP3 is realized by using the LSI for system management. The following
management features are provided by EXPRESSSCOPE Engine SP3.
•
Monitoring power supply unit
•
Monitoring temperature, voltage, fan, and electric power
•
Generating System Event Log (SEL) at hardware failure
•
Monitoring OS stall by watchdog timer
•
Notification process after OS stop error occurred
•
Remote control using web browser (resetting server, power-ON/OFF, checking system event log(SEL))
•
Remote KVM feature
•
Remote control and central management of multiple servers by NEC ESMPRO Manager through
LAN/WAN, and remote KVM feature
See Chapater 3 (5. EXPRESSSCOPE Engine SP3) for details of remote control using web browser and
remote KVM feature.
Tips
Express5800/A1040b, A2040b, A2020b, A2010b User's Guide
Measured values of temperature, voltage, fan, and electric power have a margin of error.
The margin may become 10% or more depending on the operation environment.
