Hi All,
Has anyone heard of a problem with power supplies led's blinking?
I have a customer that has 2 different power supplies (ASTEC/ZYTEC)
It appears that when both power supplies are in DECHUB 900
(4.1.1 firmware) the ASTEC led's are blinking and the ZYTEC
led's remain solid..When customer pulls out ZYTEC power supply
the ASTEC led's then become solid..Customer claims that power
is not interrupted at all!!..Does anyone have any clues???
Regards,
Kevin Culp (NSU Team)

| 3164.1 | Voltage set point incorrect on Astec | NETCAD::B_MACARTHUR | Wed Jan 17 1996 10:14 | 15 | |
Kevin,
I've seen this same problem in the lab when the voltage on the +5V
output is set incorrectly on the Astec supply. We know for a fact
that some quantity of Astec supplies was built using the wrong
voltage set point, but the problem only shows up when the hub is very
lightly loaded. If your customer were to add more modules as a
load, the blinking should stop. The only way to fix it is to
correctly set the output voltage and this is not an easy thing to
do without the proper setup. If you have another Astec supply to
use in the interim, I could fix the one that you're customer is
seeing a problem with. Let me know what you'd like to do.
Regards,
Bob
