Cisco’s online library of product information. UniverCD is updated and shipped monthly,
so it might be more up to date than printed documentation. UniverCD is available both as
a single CD and as an annual subscription. To order UniverCD, contact your local sales
representative or call Customer Service.

Flash memory. The appendix “Internetworking Primer” has been included to provide the
required background for getting started with your Cisco 2500 series access server.

familiar with electronic circuitry and wiring practices and have experience as an electronic
or electromechanical technician.
