I have 2 NEC BF210/24 POE data switches (rebranded Cisco units I think) with blown power supplys.
I've been trying to purchase replacement power supplys or find someone who can repair these.
I contacted LiteOn and they were no help . . .
These look just like the PA-2461-1a units but the part number is definately a 1b which no one seems to have heard of.
