Power Supply Unit
A redundant configuration can be set with two hot-swappable power supply units (The standard version has one
unit).
The server provides a redundant power configuration that ensures continued operation of the system in the
unlikely event one of the power supply units fails.
Note
AC power supply unit has a cable tie to prevent AC cable from slipping out.
Installation
Note
The both two power supply units installed in the server must have the same
capacity. Make sure that the two power supply units have the same part number
and the same label color. If the two power supply units are inappropriate, the
system may become unstable to be shut down.
Note
In order to prevent damage of the system due to improper cooling or elevated
temperature, please do not activate the server or enclosure without implementing
any of component or blank on all of drive bays and device bays.
