If you don't hook up a cable from the controller to the backplane, probably no activity LED's.ĭrive failure lights may also require a separate set of signals, and many boards and backplanes may not support it unless they were designed as a set. JP26 and JP47 provide activity LED signaling from the controller. For the Alert state: Very light amber letters on a dark amber background. For the Non-Alert state: White letters on a solid blue background. Especially where you have a manufacturer's backplane, if you are not using their controllers and their cabling, it may well be your responsibility to work out the wiring and electronics necessary for the activity LED's.įor example, if you look at this Supermicro backplane: The display utilizes a dual-color LED back light with the following modes of operation: For the System ID state: White letters on a blinking blue background. Point is, this isn't necessarily a software thing at all. Don't remember what the problem was there, but I remember hating that my Nexenta test box had no activity lights because it was not trivial to hook up the lights. I then ran into it again when I tried taking one of those backplanes and using them with a Supermicro SAT2-MV8 controller. ![]() A later rev of the backplane "fixed" that and AIC even started providing 3Ware-compatible cabling eventually. ![]() The 3Ware controller, IIRC, presented headers with the drive activity status which then had to be wired to the AIC SATA backplane, but the signal levels were wrong, so we had to have little PCB's designed to piggyback on the AIC backplanes that had (IIRC) TTL inverters on them. Drive LED's are generally a function of your controller, backplane, and drive choices.īack in the mid-2000's, we were selling the AIC 24-drive chassis with some 3Ware 95xx controllers in them. ![]()
