I have an SRX220, which uses an external power brick, and I can hear a very audible crackling noise coming from the power brick. I submitted an RMA request, and the new power brick has the same problem. Is this normal? I've never heard this kind of noise from a power brick before, and it doesn't generate confidence in its safety.

Although I only have an SRX100 my power brick has never made anything remotely like those noises. Is the input power clean? If you have an online or interactive UPS I'd try plugging it into one of those. Otherwise I'd say go back to Juniper.
