Power Supplies
The IBM c-type SAN directors support the 3000 W AC power supply (AC input and DC output).
The SAN768C-6 supports up to 16 hot-swappable 3000 W AC power supplies. The SAN384C-6 supports
up to eight hot-swappable 3000 W AC power supplies (AC input). The SAN192C-6 supports up to four hot-
swappable 3000 W AC power supplies (AC input).
The 3000 W AC power supply unit may be connected to either 220 V or 110 V AC power sources. When
connected to 220 V each PSU has a maximum output capacity of 3000 W. When connected to 110 V each
PSU has a maximum output capacity of 1450 W.
Each power supply module monitors its output voltage and provides the status to the supervisor. In
addition, the power supply modules provide information about local fans, power, shutdown control, and
E2PROM to the supervisor.
Note :
• The minimum number of AC PSUs required to achieve grid redundancy on each of the IBM c-type SAN
switches and directors differ. For more information see the AC Power Supply Requirements for Grid
Redundancy section.
• When PSUs are in 1450 W mode and the system is configured in redundant power mode, the total
power available to the system may not be sufficient to power all modules installed in the chassis. For
more information, refer to the Cisco NX-OS Fundamentals Configuration Guide.
