USB connectors
Two USB 3.0 connectors on the front of the device support activities carried out
by the service technician. The maximum length of the external cable is two
meters for the USB connectors on the front.
Another four USB connectors are available on the rear of the device
(4x USB 3.0).
Power supply unit (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 PSUs Platinum) 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).
Advanced Thermal Design
The Advanced Thermal Design 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.
