3.4 System Synchronisation Clocks
Acc. to the PXI specifications, the Schroff PXIe system routes the PXI_CLK10 to slot 1-8 and
PXIe_CLK100 and PXIe_SYNC100 to the peripheral slots 2-8.
PXI_CLK10 is also routed to the external BNC connector 10 MHz REF OUT at the chassis rear
side.
All clocks/timing signals are generated by the PXI-5 compliant Schroff PXIe Clock Module.
When a 10 MHz reference clock signal is present at the System Timing Slot or the rear panel
connector 10 MHz REF IN, PXI_CLK10, PXIe_CLK100 and PXIe_SYNC100 are phase-locked to
this reference clock signal according to the following table:
The source for the reference signal is selected automatically.

3.5 Schroff PXIe Chassis Management Module (CMM)
The Schroff PXIe Chassis Management Module (CMM) allows access from the operating
system to all important chassis functions. The CMM provides an I2C interface which is
connected to backplane SMB (system slot pins XP3-a3, -b3).
The CMM:
• Monitors all chassis voltage levels
• Monitors and control the power supply
• Monitors and control the fans
• Monitors the chassis temperatures (inlet and outlet)
• Controls SYNC100 frequency from clock module
• Controls the chassis status LEDs

3.6 Power Supply
The PXIe system is powered by a 600 W power supply with wide range input (100 - 240 VAC).
The power supply contacts via a connector to the PXIe backplane.
The power input is provided by an AC mains/line module with IEC 60320-C14 connector,
integrated mains/line fuses and line filter.
The fuse rating is 10 A slow blow (T10AH250V).

Hazardous voltage!
Parts of the power supply may be exposed with hazardous voltage. Always remove mains/
line connector before carry out any assembly work.
Caution!
Your system has not been provided with a AC power cable. Purchase an AC power cable that
is approved for use in your country. The AC power cable must be rated for the product and
for the voltage and current marked on the product's electrical ratings label. The voltage and
current rating of the cable should be greater than the ratings marked on the product.

3.7 Power-on behaviour
The power-on behaviour depends on the setting of the inhibit mode switch at the rear panel.
When the inhibit mode switch is set to "DEF", the CMM controls the power supply inhibit, the
chassis can be powered by pushing the power button at the left front side.
When the inhibit mode switch is set to 'MAN', the chassis boots when AC-power is applied,
as long as Pin 5 at the DSUB connector is not connected to GND.
3.8 Voltage monitoring
The female DSUB-9 connector allows remote monitoring of the system voltages.

Please note the following:
In order to ensure a proper function of the DEF and MAN settings, the BIOS settings in the
embedded controller must be adjusted.

- Set BIOS Power Loss Control to "Remain Off".
MAN Mode:
- Set BIOS Power Loss Control to "Turn On".

16 Cooling R1.5, April 2021
4 Cooling
The PXIe boards and the power supply are cooled by forced air convection through two 12
VDC axial fans (258 m³/h (172 cfm)).
Figure 5: Air Flow
Caution!
To maintain proper airflow, all open slots must be covered with filler panels. The filler panel
should include an airflow baffle that extends to backplane.
