Power OFF
Follow the steps below to turn off the power. If NEC Express5800/ft series is plugged to a UPS, see
manuals included with the UPS or the application that controls the UPS.
1.
Perform a normal shutdown from OS.
The system will be powered off automatically. (Note: the POWER switch on the primary
side will remain illuminating when AC power is supplied.)
2.
Power off all peripheral devices.
POST Check
POST (power-on self test) is a self-test function stored on the motherboard of NEC Express5800/ft
series.
When you power on the server, POST will start automatically to check the motherboard, ECC
memory modules, CPU/IO modules, keyboard, mouse, etc. It also shows startup messages for
various BIOS setup utilities.
According to the factory default settings, the “NEC” logo appears on the display while POST is
being performed. (To view details of POST, press
Esc .)
TIPS:
„ You can view POST details from the beginning without pressing
Esc key when the BIOS menu appears. Select [System
Configuration] – [Advanced] and set [Boot-time Diagnostic Screen]
to “Enabled” (see Chapter 4).
„ You can view the test items and details from a management PC
where ESMPRO Manager is installed.
You do not always need to check POST details. You will need to check messages when:
„
You install a new NEC Express5800/ft series.
„
A failure is suspected.
„ You hear several beeps between the time of the power-on and OS start-up.
„
The display unit shows an error message.
