In this context, a single point somewhere where all grounds are wired to. Imagine three or four drives next to each other in an enclosure. The temptation is to connect a wire from ground to drive 1, then a wire from the ground terminal on drive 1 to drive 2 then drive 3 then drive 4 and leave it like that. The correct way, with "star wiring" is a wire from ground to drive 1, a separate wire from ground to drive 2 etc. All the ground wires connect to a physical common point. The wires radiate out like the points on a star :) Steve Blackmore -- ------------------------------------------------------------------------------ All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
