Narrative:

While cruising at FL220 approximately 60 mi southeast of fargo VORTAC, a TA was received from TCASII. Subject traffic on TCASII at 2 O'clock, 6 mi, and 900 ft below. Approximately 1 min later when subject traffic was at 5 O'clock and 1.75 mi, we received an RA commanding a climb. We complied with the command to climb by placing the vertical speed needle in the green arc as depicted by TCASII at approximately 1500-2000 FPM. We accomplished a level off at FL225 and advised ATC (ZMP). Center indicated no traffic above us and that he had no problem with our complying with the TCASII RA. TCASII was written up in logbook after landing in fargo. TCASII placed on MEL as a precaution.
