[cisco-voip] Redundancy to the endpoint

[Lelio Fulgenzi]

I used to like those RJ21 connectors - made swapping out a blade very quick. Do they still have modules with that as an option? Could go with cat4k or 6k with those modules I guess.

  Cisco's campus model stops being redundant at the access layer switch, which 
  (according to cisco) should have high port density.  When one of those 
  fails, devices connected to those dense ports go dark if they're only 
  connected to one switch.  We had a 3750-PoE-48 go down last Friday, and 48 
  phones are now blank.  Cisco initially said they didn't have another one to 
  send us until July 21, but I persuaded them to send a 3560 as a temporary 
  replacement, so with a minor configuration change we should be back in 
  business later today.  Nevertheless, losing 48 phones is still a big deal 
  for us, and even if we had the money to support a fully-redundant switch, 
  there's still a significant outage while the fault is detected and the patch 
  cables are swapped.  I wonder what other folks do in anticipation of a 
  high-port-density switch failing, and if there's a likelihood of improved 
  redundancy at this level in the future?
