AC Power Systems

Each AC powered chassis contains two fixed configuration AC PDUs or two modular configuration AC power shelves for 2N redundancy.

•In the fixed configuration power system, each PDU accepts one AC power rectifier. The PDUs and AC power rectifiers are field replaceable.

•In the modular configuration power system, each power shelf can contain up to three AC PMs. The power shelves and the AC PMs are field replaceable.

Note Depending on the hardware deployed at your site, your system may not consume the maximum power supplied by the power system.
