Thank you pct88.
This morning changed the IP on the HAI OPII again and moved the connection over to the new switch.
Did a quickie cable test with the built in diagnostics on the TP-Link switch. It is showing open and a cable fault and seeing error packets.
I had left the run alone originally using a couple of patch panels to bring the connection to one switch. That said I do have another new switch adjacent to it but its a pita to run another cable.
I will use my new cable testing tool first and fix the patch over; concurrently will run a temporary cable over to the HAI panel to see if it makes a difference.
Turned on IGMP snooping.
Turned storm-control and tweaked rate down to 1024 Kbps.
I also set the port to 1/2 duplex at 10 Mbps.
Initial test showing the TP-Link Cable diagnostics
I haven't done anything with cable yet. HAI PCA is showing the Omnistat comm issue right now.
Omnitouch 5.7's showing zero (0) for ambient temperature and HAI OPII panel has lost 2 minutes in about 10 just now.
Temperature and combo temperature/humidity sensors are all fine. Not touching Omnitouch 5.7e's for the time being.
Disconnected the panel and checked my patch panel to patch panel connections.
Patch cables were fine. Wire mapping is incorrect patch panel to patch panel. PITA - repunching down ends right now.
This is what I get for patching cables to patch panels in the dark....and doing it fast and not having the proper tools to check my stuff.
I checked patch panel to patch panel cabling and all is OK. Wire mapping is fine now. I had to repunch down a couple of cables.
That said though when I plug the HAI OPII I still see an open connection on the switch.
Testing the cable I plugged a generic switch instead of the HAI panel and the connection is normal.
Next making up a new cable to test the switch to HAI panel connection.
Tested with two TP-Link managed switches, GB unmanaged switch, 100/10 unmanaged switches, a couple of really old unmanaged switches and new patch cables.
The two managed switches directly connected to the HAI OPII show an open cable fault; no matter what I tried. I can venture a guess here but will not. I don't think though its a hardware issue; but in a way it is relatively speaking.
The older gb unmanaged switch doesn't show a link even though one is there.
This kind all goes back to an old style network connection that you really can't do anything about relating to this problem. This is a best guess right now. Note that I have more than 50 devices on my network and lately its closer to about 100 devices which is more than I had 10 years ago.
I am sort of rearranging my network such that I have more than two internal networks anyways using the PFSense firewall.
Moved the HAI OPII connection back to the separate LAN behind the internal firewall that I am using.
All the above testing and playing is helping me a bit with thoughts relating to a new linux based plugin for the HAI OPII panel.
Initially I wanted the plugin to run on some little boxolinux small footprint arm based CPU (like a pogoplus or similier).
That said maybe the plugin / device should also have two network interfaces; one in and one out and still fit inside of the HAI OPII can. Over the years have played with those small pocket sized mini do-what routers and maybe a bit more tweaking could turn one of these into a combo plugin appliance thing for the OPII panel.
I can't really modify the board but this way I can do a bit more with the network interface on the board. The plugin would be sort of appliance like and would provide a new ethernet interface to the HAI OPII board.
I have a few of these around such that will give it a go and install one inside of the HAI panel. Its a bit cluttered these days but it should not be an issue.
On a side note ...
Been playing a bit with LinuxMCE and do like the methodology that the software/hardware is a router / firewall to its consoles on a separate network
Update - 18th of September, 2013
For kicks created a separate VLAN and put the HAI OPII panel on said VLAN. I could see the comm issues crop up as soon as I moved the panel to the specified port / VLAN.
Looking for a micro router today. I have a little Asus but it only has one port. I also have a Sapida but its a bit bigger than the Asus.
I have one but it only has one port on it. That said found a few out there in internetlandia.
