The unit number is the number used by the host to identify each PT when more than
one PT is connected to a single host.
The unit numbers that can be set depend on the type of host used, as follows:
• C200HE(-Z):
Unit numbers 0 to 3 (up to four PTs for each port of the host)
• C200HG(-Z), C200HX(-Z), CS1G/H, CS1G/H-H, CQM1H, CJ1G, and CJ1G/H-H:
Unit numbers 0 to 7 (up to eight PTs for each port of the host)
