I'm pretty sure they don't either, but never know.

Ah yes, the EIF24G.  I have two of the -A models here and a pallet of 
them in a warehouse.

I know exactly the failures you are talking about - in our case, we got 
the switches with QC tags stating "Dead ports".  A firmware update and 
the ports magically came back and started working again.  Originally 
figured an ASIC or similar had gone south and taken out a group of ports.

I'm actually pretty happy with the switches, they're pretty durable and 
we've got the two at home acting as the 'edge' switches for things like 
the HTPC, NAS, DirecTV receivers, etc.

Before we needed the extra ports, had the foundry 10GCF which has a 
similar less then stellar history.  Mess of a witch, but it held up well 
for 2 years until the EIF24G-As came.

I believe both the 10GCF and the EIF24G's are of the same vintage of 
Accton hardware.

I got a bit... frustrated with the switch modules on the 1655 many 
times.  CLI makes me want to puke.  Would get into a wonky state, and I 
had to factory reset it via the web ui.  Finally just gave up with the 
CLI and used the web ui to configure it.
