Serial label pull tab
The serial label pull tab contains important information about the server like the BMC
username and password.
To access the serial tab:
A. Pull the serial label tab from the chassis.

Operations 18
Operations
Power down the server
Before powering down the server for any upgrade or maintenance procedures, perform a
backup of critical server data and programs.
IMPORTANT:
When the server is in standby mode, auxiliary power is still being provided to
the system.
To power down the server, use one of the following methods:
•Press and release the Power On/Standby button.
This method initiates a controlled shutdown of applications and the OS before the server
enters standby mode.
•Press and hold the Power On/Standby button for more than 4 seconds to force the server
to enter standby mode.
This method forces the server to enter standby mode without properly exiting applications
and the OS. If an application stops responding, you can use this method to force a
shutdown.
•Use a virtual power button selection through BMC.
This method initiates a controlled remote shutdown of applications and the OS before the
server enters standby mode.
Before proceeding, verify that the server is in standby mode by observing that the system
power LED is amber.
Using Power Control function through BMC
The following options are available when using Power Control function through BMC:
•Power On—Similar to press and release of the Power On/Standby button
•Power Off—Similar to the press and hold of the Power On/Standby button more than 4
seconds.
•Power Cycle—Power off and then power on the server
•Hard Reset—A forced reboot that does not reach standby

Operations 19
Wistron BMC
BMC is a remote server management processor embedded on the system boards of
RB238G13-U08 servers. BMC enables the monitoring and controlling of servers from remote
locations. Wistron BMC management is a powerful tool that provides multiple ways to
configure, update, monitor, and repair servers remotely. BMC (Standard) comes preconfigured
on Chenbro servers without an additional cost or license.
Using BMC
To log-in, you need to enter your username and password. You can find this information
printed in the serial label pull-tab (Link).
Firmware Information

Operations 20
To check the current firmware version that is installed in your server, from the BMC menu bar,
