Hello: About an year ago, I purchased two 3Com (each with 1-HiPer NMC, 2-Hiper ARC & 10-Hiper DSP). I was planning to set them up for a friend. I downloaded and installed software (On some of the components): HiPer NMC: 8.6.3 HiPer ARC: 5.3.110 HiPer DSP: 3.5.12 After about 1+ year of inactivity, I decided to setup 3Com. I noticed that some of the HiPer DSP has old software intalled on them. Using TCM, I decided to update the software and get the following errors: HiPer NMC: Error: No .nac file Uncheck the slot or enter a new file name Hiper ARC: Error: (Same) HiPer DSP: Error: (Same) I noticed that on the Software Download screen Slot colum show cards correctly. NAC/DMF File, SDL File & Status columns are blank. As I said, last year I had done Software Updates but now I can not. Can somebody help me by showing the light? Kirti
