CPU Panic

Tru64 v5.1B
Dual CPU
2G memory

PROBLEM:  cpu 0 panic system uncorrectable machine check

ON BOOT:  error identifies problem in Bank 3 DIMM 0 Byte 4

  * We have swapped to a different chassis/motherboard/etc using only same CPUs 
and memory
  * CPU0 swapped with spare
  * CPU0's memory swapped with spare
  * We then took the original CPU0 and put it into CPU1 (still cpu 0 panic)
  * We reduced the memory down to 1M (so that above dimm/bank was empty)
  * We have swapped the memory between the two banks (expecting to see the error 
move, it did not).

We have replaced everything, tried moving CPUs and memory (cpu0<->cpu1) to see 
if the problem traveled.  We are still crashing and always on boot we see the 
same memory error even when memory was swapped out and when no memory was in 
that bank.

Reason for a broken fuse in the fan control of a GS140

Hi managers,

I hope, someone is still watching the list. This is more a hardware question.

I have a GS140 (converted from a 8400). The fan caused a machine stop. Since the
fan wasn't working anymore. I checked the power supply to the fan. Everything
was normal, no power supply was broken. Therefore I pulled the fan housing. In
the housing is a controlling unit installed. The controlling unit has a 6.3 A
fuse that protects the input. The fuse was broken. After replacing the fuse, the
fan started working again (I provided 48V by a external power supply).

Since everything seems to be in workng condition again, I'm curious, why the
fuse broke. Is anybody out there who has gotten across the same problem? May be
the fuse is a bit to close to the maximum current that is needed by the fan.
I've seen a peak of 7 A during start of the fan. Would it help to replace the
fuse by a 8A type?

Thank you very much.

SUMMARY:ZIP & UNZIP Software for Tru64 Unix

Thanks a lot to:
Olle Eriksson, Franz Fischer, Alen.Yokhanis, Gutierrez, Richard Jackson,
Jeffrey for providing the source, Link & files for ZIP & UNZIP. 
We needed only ZIP & UNZIP SW as there is some Oracle script which while
running uses ZIP & UNZIP SW. Any other form of zipping SW was not
supported ie.-GZIP, BZIP etc.

Following are the Links:

Thanks & regards.
