Hi List: I am trying to program a 3Com TC Chassis. I noticed that HiPer NMC, HiPer ARC & HiPer DSP, all have quite a number of fields to program. I have printed 7-8 manuals on these cards but I still have not found the documentation which explains in detail each field, their explanation and various settings. Can someone tell me the name of the document for each of these cards where I can find such information? Thanks.
