Possible Reasons
The Blade PC is off.
The enclosure power supplies
have failed or the blade's system
board power circuitry has failed.
A bad ROM upgrade (checksum
error) has occurred and the
blade is running out of recovery
ROM.
The VRM has failed (this
condition will be reported by the
enclosure as a VRM failure).
Processor thermal protection is
activated.
CPU has failed.
The enclosure power connector
for the blade has failed or the
enclosure power supply has
failed.
System board (hot swap circuitry)
has failed.

Possible Solutions
Press the power button on the Blade
PC.
Check to see if the enclosure power
supplies have failed. If the enclosure
reports that the health is good, try the
blade in another bay. If the failure
follows the blade, replace the system
board.
Retry flashing the ROM. If the error
still exists then the ROM flash image
may be corrupt. Try downloading or
using another ROM image.
Replace the system board.
Ensure that the system fans are
functioning properly (see table D-8)
and that the enclosure has adequate
ventilation. If so, check the processor
heat sink. Replace the system board if
the condition still exists after
corrective actions have been taken.
Replace the system board.
Move the blade to a different bay to
see if the blade functions properly. If
this corrects the problem, there is a
problem with the enclosure
backplane. Contact HP or your
authorized service provider for
replacement parts and service.
If the solution above did not resolve
the problem, replace the system
board.
