Getting a lot of pre rs errors 100s hub5

[smithy01793]

Hi all hope you are all well. 

So I have 1gig and hub5. 

I am getting 100s of pre rs errors on my 3.0 down stream channels it's only been up for less than 2 days since last reboot.

From 300 to 1300 across all channels.

But no post rs errors. 

Can you tell me what this means please and if it is a developing problem. 

Thanks

It is not a problem.  They occur when the hub is reset and there are a few moments of gibberish while it syncs.  Double check that the post-R/S are still zero and don’t worry about rising pre-R/S as they are self-correcting in flight.
