Important notes on preparing your FUTRO S720/S920
or ESPRIMO A525-L for use via the Power
over Ethernet module
With the aid of the Power over Ethernet module, you can operate the FUTRO S720/S920
or the ESPRIMO A525-L over the LAN without any additional power connection.
You will need a suitable network infrastructure for this.
To operate the FUTRO S720/S920 or the ESPRIMO A525-L via the Power over Ethernet module,
midspan devices conforming to IEEE 802.3at and shielded CAT 5 network cable or higher quality
cable are required. Endspan devices will only be supported in conjunction with a hardware
classification. Fujitsu recommends the use of the following midspan devices:
• 1 port midspan from Microsemi PD-9501G: S26361-F1744-L10
• 12 port midspan from Microsemi PD-9512G: S26361-F1744-L20
Because of the limited power output, not all hardware configuration levels are possible for
operating the FUTRO S720/S920 or the ESPRIMO A525-L via the Power over Ethernet
module. The following hardware configurations are possible:
Internal memory expansion
mSATA module (FUTRO) / HDD (ESPRIMO)
SmartCard reader
Speaker
WLAN
PCI/PCIe cards or extra interfaces
Depending on the system utilisation, occupancy of external interfaces (excluding the keyboard,
screen, microphone and headset) may cause overloading of the Power over Ethernet module.
In order to support the largest possible occupancy of interfaces, if an overload occurs the
performance of the system is lowered by a reduction in the CPU frequency. If the CPU frequency
is permanently reduced, the occupancy of the external interfaces must be checked and reduced
accordingly to prevent damage to the Power over Ethernet module or the midspan. Alternatively,
the system can also be connected via a suitable AC adapter (see note in this Operating
Manual). The system must be switched off before the AC adapter is connected.
If you are perhaps retrofitting a FUTRO/ESPRIMO with a Power over Ethernet module,
please pay attention to the maximum possible expansion. If PCI/PCIe expansion cards are
installed (FUTRO S920), these must be removed, otherwise the Power over Ethernet module
or the midspan may be overloaded and switched off automatically.

for use with an external graphics card
The FUTRO S920 may in addition be fitted with a graphics card. Only specially approved
graphics cards are allowed to be used. If a graphics card is retrofitted in the FUTRO S920, it is
important to note that a 65W AC adapter is needed for operation. The FUTRO S920 without a
graphics card is only supplied from the factory with a 40W AC adapter as standard.
