Server Features Hot-Plug Fans HP ProLiant ML530 Generation 2 servers support redundant hot-plug fans. If the primary fan fails, the server generates a system alert and commands the redundant fan to function automatically. The redundant hot-plug fan protects the various server components from overheating, provides rapid serviceability, and minimizes the risk of system interruption: • Standard: One hot-plug CPU fan, one hot-plug I/O fan, two required hot-plug drive fans, and one redundant hot-plug drive fan • Optional: One redundant hot-plug CPU fan and one redundant hot-plug I/O fan Hot-Plug Power Supplies Improved power supply performance ensures that a single power supply provides sufficient power to the entire system. Complete redundancy can be achieved by installing only one additional power supply. The standard and redundant power supplies run simultaneously under normal operating conditions. The redundant hot-plug power supply ensures the delivery of electricity to the server, provides rapid serviceability, and minimizes the risk of system interruption. In case of a loss of redundancy, the system sends an alert of the failure to the system administrator. The failure does not cause any loss of power, and the failed unit can be replaced without having to power down the server or save system data. • Standard: One hot-plug 600-W power supply • Optional: One hot-plug 600-W power supply Hot-plug power supplies also have advanced features that ease operation: • Auto Line Sensing capability automatically selects the appropriate line voltage. • Power Down Manager ensures that ProLiant ML530 Generation 2 servers deactivate in a manner that safeguards data and system integrity. 1-8 HP ProLiant ML530 Generation 2 Server Setup and Installation Guide
