Functional overview
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
(2x USB 3.0 and 2x USB 2.0).
Power supply
In its basic configuration, the server has a hot-pluggable power supply unit that
adjusts automatically to any power voltage in the range from 100 V to 240 V
(Platinum) or 200 V to 240 V (Titanium). As an option, the power supply can be
expanded with an extra power supply unit to create a redundant power supply.
If a power supply unit fails, the redundant configuration assures continued
operation. The defective power supply unit can be replaced during operation
(for further details see the "FUJITSU Server PRIMERGY RX2540 M1 Server
Upgrade and Maintenance Manual").
