Damage of PMC Module
The PMC Standard VITA 32 - 2003, Revision 1.0a, specifies a maximum
total power consumption of 5.15W per PMC module. The Gigabit
Ethernet/82543 PMC Module in its standard configuration may exceed
this value.
Therefore, it is necessary to synchronize the base board's power supply
with the Gigabit Ethernet/82543 PMC Module power requirements. Due
to the high power dissipation, forced air-cooling is necessary.
Damage of power supply circuits
The power supply circuits on the carrier card may be overloaded if more
than one Gigabit Ethernet/82543 PMC Module module is assembled. This
results in permanent damage to the carrier card.
Therefore, make sure that the carrier card's 3.3V and 5V supply supports
the power requirements as described in
The current requirement for one PMC module is:
3.3V Rail : 1.56A typical
5V Rail : NA
This results in a typical total power consumption of 5.15W. However, the
carrier card should be able to provide maximum current requirements as
given below:
3.3V Rail : 1.73A maximum
