Important notes on preparing your FUTRO S720/S920

or ESPRIMO A525-L for use via t

he Power

over Ethernet module

With th e aid of the P ower over

Ethernet module, you can operate the F UTR O S720/S920

ortheESPRIMOA525-Lovert

he LAN without any ad ditional power connection.

You will need a suitable n

etwork infrastructure for this.

To opera te the FUTRO S720

/S920 or the ESPRIMO A525-L v ia the Power over Ethernet module,

midspan devices con for

ming to IEEE 802.3at and shielded CAT 5 network cable or higher quality

cable are required. End

span devices will only be supported in conjunction with a hardware

classiﬁcation. Fujit

su recommends the use of the following midspan devices:

• 1 port midspan from Mic

rosemi PD-9501G: S26361-F1744-L10

• 12 port midspan from Microsemi PD-9512G: S26 361-F 1744-L20

Because of the limit

ed power output, not all hardware conﬁguration levels are possible for

operating the FUTR

O S720/S920 or the E SPRIMO A525-L via t he Power ove r Ethernet

module. The follow

ing hardware conﬁgurations are possible:

ds or extra interfaces

none

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 s upport 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 exte rnal interfaces must be checked and reduced

accordingly to prevent damage to the Power over Ethernet module or the midspan. Alternatively,

the system c an 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 FUTR O/ESPRIMO with a Power over Ethernet module,

please pay attention to the ma ximum possible expansion. If PCI/PCIe expansion cards are

installed (FUTRO S920), these must be removed, othe rwise the Power over Ethernet module

or the midspan may be overloaded and switched off aut omatically.

for use with an external graphics card

The FUT RO S920 may in addition be ﬁtted with a graphics ca rd. Only specially approved

graphics cards are allowed to b e 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. T he FUTRO S920 without a

graphics card is only supplied from the factory w ith a 40W AC adapter as standard.
