80V AC in the case (RV320)

Mon Feb 13, 2017 1:37 pm

A few weeks ago i re arranged some equipment in a 19" 9U wall rack.

I was about to move a Cisco RV 320 router, and grabbed it with one hand and happened to touch my HP 24 port switch with my other hand. I immediately sensed a burning feel in the "grounding" hand beneath the switch. It was not a static type of discharge, and longer lasting.

I sent in the RV 320 for a check at the dealer after my electrician found it odd to give current in the case. At the dealer they measured 80V AC between ground and the case. I got a replacement unit, but it has the same 80V AC between the case and ground.

Is there a fault in these two units, or is this normal for floating ground wall wart equipment?
Maybe this is not a suitable type of product for rack equipment.

Do this effect go away if i change it for a RV 325 + rack mount kit?

I chose the Cisco because i thrust the brand and did not expect any problems.
