On yesterday, I had 5 HP Jet Direct external printer servers to stop working. All had the same symptoms. The status light went off and the activity light stayed green. I had them to reset the servers by unplugging, holding down the test button and plugging back in. The status light came on briefly and then went off and the activity light stayed green.
What would cause all five to fail and they are not all in the same site? Are they dead?
