Installation and Hardware description
2.4 Installing the M5000 into the VME Chassis
Slot Selection
You can install the M5000 board into any VMEbus slot in a 6U VMEbus chassis as long as the
daisy chains for the bus grant and interrupt acknowledge signals are continuous, from the left-most
slot, to the slot in which the M5000 board is installed.
The metal strip along the card edge is for electrostatic-discharge. Some chassis include a spring
contact in the front of the board guide that connects the metal strip on the board to the chassis
ground while the board is inserted. Once fully inserted in the chassis, the discharge strip has passed
by the spring contact and is no longer in connected to chassis ground.
Each of the two metal strips are connected to board signal ground through a 10K resistor
In accordance with the VME64 Specification, a M5000 main board installed into the left-most slot
will act as the System Controller. Consequently, system controller functions are also enabled.
Power Consumption
Typical values for power consumption are shown in Table 2-10. In Idle Mode, no processors are
booting, and no data is transferred. In Active Mode, processors are booting and running memory
tests.
When driving the VME bus, the system power consumption goes up, and the additional power is
dissipated in the termination resistors of the VME bus. The amount of additional power depends on
the VME bus traffic pattern and varies from 3.5 to 6.0 W.
Warning! Do not install the board into a powered system!
Warning! The M5000 hardware requires forced air-cooling for reliable operation.
Commercial and Rugged Level 1 boards require 300lfm, Rugged Level 3 requires
600lfm. For Rugged Level 2 contact VMETRO.. Operation on extender boards is not
recommended.
Note – The numbers shown in Table 2-10 do not include any power drawn by PMC modules
mounted on the board, nor increased system power consumption when driving the VME
bus.
Note – As a guideline, a 5 slot VMR64 chassis with boards similar in capacity to the M5000
should have a power supply able fo providing 60A per supply voltage.
