Yet Another Agilent 6890N LAN Issue
Posted: Sun Oct 10, 2021 11:40 pm
We have a 6890N that's behaving rather strangely. It will routinely fail to connect or disconnect from the MassHunter instance. When pinging it, about 50-75% of the pings aren't coming back, so it appears to be haphazardly losing packets. It has gotten worse over the past week, where I was earlier seeing 25-50% packet loss. I've tried swapping both the Ethernet cables and the switches for known good units, which doesn't seem to fix the issue.
Also rather strange is that all of our other GC-MS's indicate a 100 Mbit/s connection at the switch when plugged in. This problematic 6890N only lights up the 10 Mbit/s connection LED.
There's no issue with the 5973 Network MSD that's attached to it, which is behaving normally.
I still haven't been able to fix my last 6890N LAN issue, which was similar but was a complete comms failure, rather than this instance which is a partial failure (but bad enough to prevent setting up runs).
