Are the LED pins for the LED? |
|
|
Okay, this is a stupid question....but,
My new build has gone great... 3800X2 and all SCSI drives. The only problem
so far is the HD LED wasn't lighting up. Seeing that the 80-68 pin adapter
on one of the drives has 2 pins marked LED, I figured what the heck and
hooked the case HD lead to it. It works (this is the stupid part). It seems
on previous builds with other SCSI drives, the HD LED worked from the mobo.
Is it OK to hook it up to the HD adapter? |

Very unlikely unless the mobo had SCSI onboard.

Yes.
Of course it only works for the drive it is hooked up to.

The drive activity led shows only activity to that specific drive.
The controller's led shows all activity on that (scsi) bus.
If the controller is in a slot (PCI) then the motherboard led is going
to show activity on the IDE channels only. |

You're right. I have a SCSI drive on another machine that I thought was
showing activity, but I just checked it and only the IDE drive lit the LED.
For some reason, I thought otherwise...

Most LED connectors pull the cathode with an open collector output
through a current limiting resistor and the anode connects to +5V. So,
you can connect multiple LED outputs to one LED. But you'd better check
the specs first or measure what's going on. |
