Problem with sd3200 clock after reaplacing sbch + uguy

[likid0]

Hi,

We had serveral problems with GSP and UGUY on a SD3200, cell resets/problems with the gsp bus,etc. we replaced both parts, and all is working ok, but we have a problem with the time in the npars, the clock goes to fast, every 5 minutes the servers time goes forward 2 minutes, so altough we are using ntp server, and we do, xntpd stop, ntpd ntp.server, xntpd start, the server can't syncronize because the offset gets bigger to fast. ntp configuration on the server is correct, before we changed the gsp/uguy they sincronized ok agaisnt the ntp servers.

The date/time on the GSP is ok, it's only on all the npars/vpars on the SD that the clock goes faster. we updated the firmware on all the components to the last level but the problem is still there.

The errors in syslog on one of the servers:

Nov 20 11:10:45 m xntpd[20]: Unsynchronized, possible remote server failure  or defective hardware clock
Nov 20 11:21:19 m xntpd[21]: Unsynchronized, possible remote server failure  or defective hardware clock

The only thing I see , is in the uguy leds, the PM status, only has 2 leds lit.  so the MOP and USB are not working, that doesn't look good.

Is the hardware clock in the uguy?. what should we do?.

Hi,

yes, the UGUY contains the clock circuits.
The described time drift is definitely out of the specifications.
So the used UGUY has an issue and should be exchanged.

Kind Regards

Yes replacing the Uguy did the trick, the clocks working perfect now
