Anyone know the LED pinouts on a Megaraid 1600?

You know, for attaching LEDs for Drive Activity, Dirty Cache and such.

I already have the 1.0MB User's Manual and it says NOTHING about them.
 
The PDF is low res so it's of no use.

Call LSi to get them if you really need to have this.

I know that JP17 is dirty cache from the 1600E...

Cheers!
 
Thanks Shuttleteam. 🙂

What confused me is they are labeled "JP" which to my mind means JUMPER. Also, in the upper lefthand corner of the card, right near the mounting bracket are some visually-identical to JP17 "pins" with jumper blocks already on them....I didn't want to connect an LED and possibly short the card out!

I wanted to check w/the Authorities first. 😀

Right under JP17 (which is labeled Dirty Cache, btw...the writing is tiny; almost can't see it!" there are more pins labeled "SCSI ACT". There are four pins...I assume two for each channel, right? I'm so scared to connect anything!!! My precious card *KAPOOFF!* would upset me just a little.

SCSI ACT is the activity LED for (as you guessed) SCSI activity. I don't use these as the backplanes have status LED's that shine into a optically conductive acrylic rod embedded in the hot swap tray to the front of the bay so you can see activity and offline status.

When you have loads of drives (in time you will!) you can connect an LED to each drive. There is an LED jumper on each drive for this purpose. This way you can see which drive is active.

Cheers!
