Cisco Secure Network Server 3600 Series Appliance Overview

Cisco Secure Network Server 3600 Series Appliances

Cisco Secure Network Server (SNS) 3600 series appliances are designed to deliver high performance and efficiency for a wide range of workloads. Cisco SNS 3600 series appliances support the Unified Extensible Firmware Interface (UEFI) secure boot feature. This feature ensures that only a Cisco-signed ISE image can be installed on the Cisco SNS 3600 series appliances, and prevents installation of any unsigned operating system even with physical access to the device. For example, generic operating systems, such as Red Hat Enterprise Linux or Microsoft Windows cannot boot on this appliance.
