TX2550 M5
Product description
Power supply unit (PSU)
The server can be equipped with:
– with up to two AC PSUs
In its basic configuration, the server has one PSU that adjusts automatically
to any power voltage in the range from 100 V to 240 V (Platinum) or 200 V
to 240 V (Titanium). 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).
Advanced Thermal Design (ATD)
The ATD option allows you to operate the system with a wider temperature
range either of 5 °C to 40 °C or 5 °C to 45 °C, depending on your system and
configuration.
V
CAUTION
In a system that is configured with ATD, only certain components which
support the respectively increased higher operating temperature range
may be installed and used. For applicable restrictions, see the official
configurator tool.
High level of availability and data security
When memory data is accessed, 1-bit errors are identified in the main memory
and automatically corrected with the Error Correcting Code (ECC) method.
Automatic Server Reconfiguration and Restart (ASR&R) restarts the system in
the event of an error and automatically "hides" the defective system
components.
The Prefailure Detection and Analysis (PDA) technology from Fujitsu analyzes
and monitors all components that are critical for system reliability.
This option can only be ordered from the
manufacturer and is indicated by the respective
logo on the identification rating plate.
