Requirements Installation
2 - 6 SPARC/CPU-54
The power supply has to meet the requirements given in the tables be-
low.
Caution
In order to protect its components, the SPARC/CPU-54 only powers
up if the 5V supply voltage is stable and within its limits. The
SPARC/CPU-54T only powers up if the 5V and 12V supply voltages
are stable and within their limits. This is in compliance with the
VMEbus specification. However, there are systems which are not
fully VMEbus-compliant. The power supplies of these systems do not
turn on the 12V supply if the 5V supply has not been loaded before.
Use a VMEbus board in the system which loads the 5V to prevent
such systems from running into a power-up deadlock.
