server. It can be upgraded to a symmetric multiprocessing (SMP) server through a
microprocessor upgrade. It is ideally suited for networking environments that require
superior microprocessor performance, efficient memory management, flexibility, and
large amounts of reliable data storage.

Performance, ease of use, reliability, and expansion capabilities were key
considerations in the design of the server. These design features make it possible
for you to customize the system hardware to meet your needs today and provide
flexible expansion capabilities for the future.

The server comes with a limited warranty. For information about the terms of the
warranty and getting service and assistance, see the
