Configuration Restrictions

A-6 D000024-000 Rev. A

The number of power supplies required to support continuous operation depends

upon the system configuration and whether DC and AC redundancy is desired.

While DC redundancy is supported for all valid configurations, AC redundancy is

limited. The maximum AC redundancy configurations for the 9120 and 9240 are

displayed in Table A-6:
