3 Installation
3.1 Safety Note
To ensure proper functioning of the
NAT-MCH CLK Module
during its usual
lifetime take refer to the safety note section of the
NAT-MCH BASIC-
Module
Technical Reference Manual before handling the board.
3.2 Installation Prerequisites and Requirements
IMPORTANT
Before powering up
•
check this section for installation prerequisites and requirements
3.2.1 Requirements
The installation requires a
NAT-MCH Basic-PCB
, where the
CLK Module
can be
mechanically fixed on to. The
CLK Module
must be completely connected and joint to
the
Basic-PCB
, before the
NAT-MCH
can be stacked into a MicroTCA backplane (as
one device). For further requirements refer to the requirements section of the
NAT-
MCH BASIC-Module
Technical Reference Manual.
3.2.2 Power
supply
The power supply for the
NAT-MCH CLK Module
must meet the following specifica-
tions:
+12 V / 0.5 A max. (only
CLK Module
, in addition to other PCBs of the
NAT-MCH
).
3.2.3 Automatic Power Up
Power ramping/monitoring and power up reset generation is done by the
NAT-MCH
Basic-Module
In the following situations the
NAT-MCH Basic-Module
will automatically be reset
and proceed with a normal power up.
•
The voltage sensor generates a reset, when +12 V voltage level drops below 8V.
