Hi, we have some 4500 and 4500L, everything Ok for some days or weeks, but at the same moments all SMs go to download SS1 and upload remains stable DS, btest download performance, became half and seems to be no solution.
Changed frequency, PoE, flexible/70-30, gps sync, reboot, firmware upgrade 5.10.4, downgrade 5.10.1, no solution. Replacing the entire Ap, or the 4500L leaving the same antenna solve the problem.
This happened with more than 10 units, it’s possibile all this units are bad?
thanks
Hi @sommodeo,
it sounds like a HW issue.
Could you Raise Ticket in the top tight of this page and drop me the ID.
You need to mention MSNs and we will RMA the radios.
Thanks, no problems I’ll make RMA throught my dealer, but how is possible that many units has this issue? It’s very annoying to change units on top of tower so frequently….

This isn’t typical for the ePMP4500, but we did see it on a few ePMP4500L units from a batch that had been stored in a humid warehouse. It looks like the FEM can absorb too much moisture under those conditions. Since then, we’ve switched hardware vendors and separated the older units in all warehouses.
I had this happen to two of my 4500L - one of them was like this at first boot, the other became like this after several months…
I’m also having a similar problem with a 4500L radio. If I provide you with the serial numbers, can you check which batch they belong to and whether they are among the radios affected by the problem?
please submit a support ticket and attach techsupport files. We will RMA radios with such behavior without any batch tracing.
