The Netfinity 4500R server is designed to be cost-effective, powerful, and flexible.
Your server offers:
• Impressive performance using an innovative approach to SMP
Your server supports up to two Intel Pentium III microprocessors. Your server
comes with one microprocessor installed; you can install an additional
microprocessor to enhance performance and provide SMP capability.
• Large data-storage and hot-swap capabilities
All models of the server support up to three hot-swap hard disk drives. This hot-
swap feature enables you to remove and replace hard disk drives without
turning off the server. The Netfinity 3-Pack Ultra160 Hot-Swap Expansion Kit
option is available to add three additional drive bays.
• Optional PCI adapters
Your server uses peripheral component interconnect (PCI) bus architecture to
provide compatibility with a wide range of existing hardware devices and
software applications. Your server supports up to five PCI adapters in the
expansion slots on the system board.
• Redundant cooling capability
The redundant cooling capability of the hot-swap fans in your server allow
continued operation if one of the fans fails. You can also replace a failing hot-
swap fan without turning off the server.
• Optional redundant power capability
You can install an additional 270-watt power supply in your server to provide
redundant power for your server. The Power Non-Redundant (NON) light
emitting diode (LED) in the group of diagnostic LEDs on the system board is lit
when the power load is 270 watts or greater with two power supplies installed.
• Large system memory
The memory bus in your server supports up to 4gigabytes (GB) of system
memory. The memory controller provides error correcting code (ECC) support
