I need some advise on These models of sup720. We have a 6513 with a single sup720 with PFC3A switching engine. We are planning to buy another sup for redundancy. The seller gave us a quote for sup720 with PFC3B.
Would this work? Two sup720 on the same box in redundant configuration, one with PFC3A the other with PFC3B.
Btw, what's the difference between these models of switching engines?
Thanks in advance to those who will reply.
