Re: 16-port 10/100/1000 Module (J4907A) failure
The module that faulted is a replacement module from HP. The original module and chassis was returned to HP. The replacement chassis took a few weeks to arrive, so I ended up taking my spare off the shelf, placing the replacement on the shelf as a spare when it finally arrived.
So, to summarize... I have had three failures, two of which HP has replaced. All three chassis were close to each other in serial number (I had ordered seven at one time).
They end in:
08S - current failure
090 - replaced
099 - replaced
The remaining siblings are:
09C
0BY
0KJ
0KM
The units that failed were populated with six or more J4907A modules. The remaining units have fewer modules.

Re: 16-port 10/100/1000 Module (J4907A) failure
Tried running some diags but the reboot into diag mode cleared the fault. :(
I removed the switch from its service location and hauled it back to my test bench. I tried 21 times to fault it by cycling RPS2 but to no avail.
One thing I have noticed is that in every case where there was a module fault, the switch had six or eight modules. and that the fault followed closely after a cycling or RPS2. I inserted two more modules to stack the odds in my favor, taking the total to eight, and cycled RPS2 13 more times.
I have the faulting 5308xl connected via module B port 7 to my 2524 on port 1. My WUG syslog shows this port #1 toggling off and on several times one minute later for the next minute. This I believe is when the switch module C faulted/crashed/rebooted.
I moved all the modules to another chassis (maintaining slot for slot) with different RPSs and will continue the testing.

Re: 16-port 10/100/1000 Module (J4907A) failure
Now if i started counting when the first fault was reported on 8/25/04... my $100,000 that is tied up in these switches that I have yet to put in production...
If I get chastized for saying "the emperor has no clothes" then so be it. I have run out of patience! Like Dan said in another thread, have I paid $100,000 for you, folks at HP, to sleep well?

Re: 16-port 10/100/1000 Module (J4907A) failure
Everytime my confidence starts to grow to the point I consider resuming the migration, along comes another speedbump. How do other people deploy this product in a 24/7 production environment and sleep at night (or do they)?

Re: 16-port 10/100/1000 Module (J4907A) failure
Is the problems with the 5308XL solved?
Is this a bad switch?
Do others have the same issues as yours?
What is the equivalent in Cisco?
Thanks.

I really don't know how to answer your question. If I really said how I felt right now, my comments would be censored. See also my other posts:

You will just have to draw your own conclusions.

Re: 16-port 10/100/1000 Module (J4907A) failure
Do you think your problems are related to the meshing?
Did you have such problems with only the 10/100/1000 J4907A modules?
What if you only use the 10/100 J4820A?
Thanks.

Re: 16-port 10/100/1000 Module (J4907A) failure
The J4907A modules are the only copper modules that I use. I purchased 8 of the J8167A bundles (HP ProCurve Switch 5308XL-48G 8-slot chassis with three 16-port modules pre-installed) so that gives me 24 of these gig modules and I have had 4 of them go bad already. HP says that statistically I should not be experiencing this many failures. With these odds, I should have put the $100,000 on lottery tickets!
I have several J4852A
12 port 100FX modules that I use to connect to my Cisco core switch and my Nortel Baystack edge switches. I already have 100 meg copper on my Nortels so there is no reason for me to put in HP 100 meg copper modules.
As to whether these modules are reponsible for my mesh problem, that is the 100,000 dollar question that even a team of engineers at HP Division cannot answer.
