I just got a Chaintech S1689 and I'm currently trying to set it up but unfortunately the manual is worthless.There is nothing about where to put the power switch connector or reset,HD light.It has numbers for where the connectors go silkscreened on the board,but there are no numbers where the pins are.To make matters worse,there is a black jumper on two of the pins.I'm quite baffled by all this.You think they would want you to be able to setup the board instead of RMAing it.
