Carlisle did not specify a timetable for West's suspension.
"Hopefully, we can get it resolved quickly," Carlisle said Tuesday, adding that he and president of basketball operations Donnie Nelson would meet with West later in the day.
Sources told ESPNDallas.com that West's suspension stems from an outburst in the locker room after the Mavs' 123-104 preseason win Monday over the Houston Rockets, although it wasn't immediately known what made West so upset. He had two points, two assists and one rebound in 16 minutes during the win.
Carlisle declined to discuss whether the issue with West's conduct was a one-time issue or something that had been brewing. Carlisle left open the possibility of West playing in Wednesday's preseason game against the Phoenix Suns.
"Until we talk to him and hash through it, I won't know for sure," Carlisle said.
West, an eight-year veteran entering his second season with the Mavs, has been diagnosed with bipolar disorder.
West's bipolar disorder was a factor in a Sept. 2009 incident that resulted in his arrest on weapons charges after he was pulled over while driving a three-wheel motorcycle in Upper Marlboro, Md. West was sentenced to eight months of house arrest for that incident and suspended for 10 games by the NBA.
West was a valuable role player for the Mavs last season, averaging 9.6 points and 3.2 assists and playing tenacious defense while seeing time at both guard positions.
