Note: To determine if the power switch assembly needs to be replaced turn on
microswitch 1 on switch block 1 (power-on override) and reconnect the
AC cord. If the system powers on within 40 seconds then replace the
switch assembly.
2. Check for loose cables in the power subsystem. Also check for short circuits, for
instance if there is a loose screw causing a short circuit on a circuit board.
3. Remove adapters and disconnect the cables and power connectors to all
internal and external devices until system is at minimum configuration
required for power-on.
Note:
Minimum configuration requirements are:
a.
1 Power supply
b.
System board
c.
1 Microprocessor
d.
1 Terminator card
e.
Memory module (with a minimum of 128 MB DIMM)
4. Reconnect the AC cord and power on the system. If the system powers up
successfully, replace adapters and devices one at a time until the problem is
isolated. If system does not power up from minimal configuration, replace
FRUs of minimal configuration one at a time until the problem is isolated.
To use this method it is important to know the minimum configuration required
for a system to power-up.
