Good but can do better...
I bought this switch two years ago.
Efficient in the announced flow rates, does not heat up particularly.
However, one thing surprised me when it was first installed.
It's the perceived quality of the power supply, and last week, I understood.
The switch started flashing all over the place like an infinity loop Christmas garland, with no network access on the equipment connected to it.
After two or three cross tests, it was obvious that the power supply was at fault.
The power supply is at fault. Change it and it's back on, but confidence is down...
