Netgear JFS524 switch failure fix (no power)

A friend's church in Norfolk had a network switch failure after a power outage. Here is the quick fix to restore use to the Netgear JFS524 (24 port 10/100 unmanaged) network switches. Symptom was switch would not power on. Standard capacitor issue. There are two on the board, one was visibly swollen and bad. Values were 2200uF at 10 volts (failed cap) and 1000uf at 10 volts (good cap replaced anyway) I think. Check values before you order in case I'm wrong on the voltages, I didn't take notes and it might be 16 volt. As always observe the polarity of the replacement capacitors and referred replacement to someone who is familiar with electronics as it's on the board that has lethal voltages. Power supply board puts out around 3.3 volts at 4 amps or some such. Good luck.
