I know we're not the only company dealing with this so I thought I'd open the topic up to discussion. What does everyone do with their defective hardware (DSP's, Hiper Arc's, NMC's, PSU's, Chassis) that is not under contract? We have over the years established a decent size graveyard of cards that no longer work. All of these cards have gone through the process of trying to reflash their code either via a ATZ{Z}, ATZ{FZ}, or a PCSDL download to no avail. DSP's seem to be the biggest problem. They will typically display the messed up LEDs on the modem untilization bar, and a variety of crash messages if consoled in. What's unusual is that sometimes you can get cards to at least boot up properly (whether or not they are reliable enough to put into service is another issue) by finding the right combination of NIC/NAC's amongst the graveyard stock. I do realize not all the DSPs are the same hardware revision. Does anyone have any other tests or procedures that they do on their problem cards, in particular Hiper DSPs? Has anyone found a method of bringing them back to life? Does anyone know of any options to get these cards working again? Commworks.....do you have any undocumented techniques for dealing with "dead" cards. Can you provide any information that may be helpful? Regards, Todd
