We have just taken a rack in a datacentre in order to host a 3560 switch. When we arrived today we found 2x 48v MCB (mini circuit breaker) on a DIN rail. We were not prepared for this and expected to see standard AC plug sockets. (We are based in UK).
Our 3560 has an input on the back already for DC however we are struggling on two things:
1. What part do we need to connect from the DC MCB to the Cisco 3560, we cannot find the part number anywhere?
2. Does the Cisco unit itself actual step the power down from 48v to 12V as the DC input on the back of the cisco says 12v 3amp?
I would be very greatful for any help offered on this as we are really stumped.
