124 Upgrade and Maintenance Manual RX2540 M4
6.1 Basic information
AC PSU
The server can be equipped with up to two AC PSUs.
In its basic configuration the server has one PSU that adjusts automatically to
any mains voltage in the range of 100 V - 240 V (AC PSU Platinum, 450 W) or
200 V - 240 V (AC PSU Titanium, 800 W). Besides the PSU, a second PSU can
be installed optionally to serve as a redundant power supply. If one PSU fails,
the second PSU in the redundant configuration ensures operation can continue
uninterrupted and the defective PSU can be replaced during operation (hot-
plug).
V CAUTION!
The AC PSU adjusts automatically to any power voltage in the range
from 100 V - 240 V (AC PSU Platinum) or 200 V - 240 V (AC PSU
Titanium). You may only operate the server if its rated voltage range
corresponds to the local mains voltage.
DC PSU
The server can be equipped with up to two DC PSUs.
In its basic configuration the server has one PSU that adjusts automatically to
any mains voltage in the range of -40.5 V - -57 V (DC PSU -48 V, 800 W) or
200 V- 380 V (HVDC PSU 380 V, 1300 W). Besides the PSU, a second PSU
can be installed optionally to serve as a redundant power supply. If one PSU
fails, the second PSU in the redundant configuration ensures operation can
continue uninterrupted and the defective PSU can be replaced during operation
(hot-plug).
V CAUTION!
The DC PSU adjusts automatically to any power voltage in the range
from -40.5 V - -57 V (DC PSU -48 V, 800 W) or 200 V - 380 V (HVDC
PSU 380 V, 1300 W). You may only operate the server if its rated voltage
range corresponds to the local mains voltage.
I The connectors for the PSUs are integrated on the system board,
therefore, the PSUs are connected directly to the system board.
