Procurve 2848 link drops randomly

[Fletcher Cocquyt_1]

Hello, we have replaced this switch once already (on June 4) - we are still seeing the gig link dropping randomly and simultaneously on two Sun Solaris 9 servers.

The firmware is I.07.32

The two servers are the only machines on the switch and the fact they log simultaneous outages tells me the switch is to blame.

Wondering what the solution might be ? try another replacement switch?
Here are the logs from the Solaris 9 servers (fully patched) - sho log on the switch does not show anything relevant - just time adjustments :

thanks for any help!

this could also be caused by a bad cable,and is the linkspeed set to autodetect on those servers or are they set manualy?

regards.

Hi fletch,

The log looks fine to me there is no toggeling, looks like normal restart / reboot / re-connect.

Have you never rebooted the Solaris or the switch during the dates in the logfile?

What is the uptime of the switch?

Have you tried fixing both the port on the switch and the Solaris box on 1000FDX?

What do the switchlogs look like?

Is the Solaris box connected to an RJ45 or a mini-Gbic? Waht kind of cable are you using?

Regards,

SCOOTER

This is from our network admin:

I just talked to HP tech support. The switch is crashing and restarting
itself. They are currently testing a software fix for this problem. They
hope to get me the new software in the next couple of weeks.

This will be a patch update to I.07.32

Thanks,

Fletch.
