Power cooling module (PCM)
AC-DC power is provided by up to four auto-ranging power cooling modules (PCMs) with integrated axial
cooling fans, up to 2 in each module. The SBB I/O modules control the fan speed. See the section that
describes the system airflow.
580W PCM
A 580W PCM voltage operating range is nominally 100V - 240V AC. Also see the System airflow section
for optimal cooling within the enclosure(s).
