I have a TC1000 includes 1 130 Amp PS + 1 hiper NMC + 1 Hiper ARC + 1 E1 DSP (ISDN Code) configuration. in the "List interface" command shows the channels are down: Interface Oper Admin Name Status Status slot:1/mod:1 Down Up slot:1/mod:2 Down Up slot:1/mod:3 Down Up slot:1/mod:4 Down Up slot:1/mod:5 Down Up slot:1/mod:6 Down Up I tested that configuration (exact cards) on 3 different chassis with same result. The only Chassis it shows up up in list interface was one chassis (3com blue) What do you think about my problem? how can I use those cards in other chassis? Thanks a lot
