Good morning, sorry for my bad English, I use translate and I will try to write simply.
Where I work they gave me a radio bridge installed and configured before my arrival.
The radio bridge is made with two ePMP1000 - Force 200 and has worked correctly since 2017 without maintenance.
Last Friday I noticed some problems with the master’s LAN connection. The switch (HP Procurve Switch 2610-24-PWR with 10/100 ports) reported communication problems, the port went up and down.
I took the slave’s power supply and the problem was solved even if the port aligned at 10Mbps. We replaced the two cables between switch->power supply->patchpanel with new CAT6.A full copper ones but it didn’t improve.
When I connected the power supply to a port of a new switch (HPE 5140 48G POE+ 10/100/1000) the device was not detected at all. I forced the port in the switch to 10, 100 and 1000 but there was no way to make it detected. I then reconnected the AP on the old procurve.
I purchased two new N000900L001D power supplies and replaced both the faulty power supply and the old one on the slave antenna as a precaution.
Then I connected to the web gui for checks.
The wireless link is ok.
The ethernet port of the slave is connected to an old 3COM 4500 24-port 10/100 Switch. There the link is correct at 100Mbps.
For a few hours it worked correctly, then it started to be unstable. The wireless link is ok but the lan port of the slave goes up and down every few minutes and sets itself to 10Mbps.
Here too we replaced the cables with new high quality ones without solving the problem.
I attach the screenshots of the error on the switch port and the system of both antennas.
I need to get the connection back up asap and we can’t afford to scout and buy new equipment (if there is absolutely no alternative).
What do you suggest?
Does it make sense to go to the roof and check the connectors and clean them if necessary?
Unless there are problems with cables and connectors, I expect the ethernet ports to work or not… not that they work unstable.
Did you replace the cable from the radio to the POE or just the cable from the POE to the switch? The Force 200 should be able to get 1000 if it’s plugged into a gigabit device, but the ePMP 1000 will only get 100.
Hi, I changed both the cable between switch and poe and poe and patch panel.
Anyway I went to the roof of the master antenna with my laptop and it connected correctly to 1G.
In any case I cleaned all the connectors on the roof and the situation improved. Now it also aligns to 1G on the new switch.
I had to put it back on the old one and settle for 100 because on the new switch the connection had problems
(“Instance 0’s port GigabitEthernet1/0/1 received an inferior BPDU from a designated port which is in forwarding or learning state.” and “The block action by dispute guard was undone on Instance 0’s port GigabitEthernet1/0/1. The port transited to learning state.”).
Not knowing if it is the antenna’s fault, the switch or something else, I connected it where I know it is stable.
Tomorrow I will try to do the same maintenance on the slave and then I will update the firmware to the latest stable on both.
As far as you know, can I jump directly from 3.0 to 4.8.1 or do I have to do any intermediate updates?
Today I also cleaned the slave connectors and the situation has stabilized. It aligns to 100 and seems stable (it hasn’t disconnected since I finished the work).
I have to evaluate whether to update the firmware.
I don’t know if it’s possible to make the jump from 3.0 to the latest or if intermediate updates need to be done. I’m waiting for answers.
