NEC sent me a flash card to upgrade the firmware on th T-1 card from 2.0 to 2.1.Followed the steps and at first the DS admin said the firmware was 15.15???Then I reset the system and it said 2.1.I just want to know if anybody out there has done an upgrade on the firmware and if you think I'm good?(Did upgrade on test switch at shop) Thanks Jayman!!
