I kept getting STO-DATA alarms, I was able to clear them but the alarms kept coming back. This is a duplicated system, the problem is on SPE A. I powered down SPE A (CARRIER) installed the new TN2211 put the disk from SPE B in, powered back up.I couldn't do any commands because I kept getting "NO BOARD". I put the orginal TN2211 back in, now I can't do any commands for SPE A, I keep getting can't access standby SPE.
