Install the Cisco SNS 3515 and Cisco SNS 3595 Hardware Appliances
Upgrade the BIOS and Cisco IMC Firmware
The following procedure describes how to upgrade the BIOS and Cisco IMC firmware on Cisco SNS-3515
and SNS-3595 appliances.
To check the version of BIOS and Cisco IMC that is currently running on your appliance:
1. Launch CIMC.
2. Click BIOS.
The running version is listed under BIOS properties.
Cisco ISE runs on Cisco Secure Network Server 3515 and Cisco Secure Network Server 3595 hardware
appliances with Cisco Secure Access Control System (Cisco Secure ACS) PIDs. Before you install Cisco ISE
on an SNS-3500 server that was previously used for Cisco Secure ACS, you must upgrade the BIOS and
Cisco IMC firmware to a version that supports the Cisco ISE secure boot capability.
Note
After you upgrade the BIOS, secure boot is enabled, and ACS will no longer boot on this appliance. Do not
perform this BIOS upgrade procedure until you are ready to convert the appliance from ACS to ISE.
Before you begin
We recommend that you use the latest BIOS and matching Cisco IMC firmware. You can download the
updated Cisco IMC and BIOS files for the Cisco SNS-3500 series appliance from
When you upgrade the BIOS firmware, you must also upgrade the Cisco IMC firmware to the same version.
Otherwise, the server will not boot.
You must use the versions of Cisco IMC firmware from the ISE downloads, which are qualified versions for
use with the SNS appliances. Versions of Cisco IMC for UCS are not compatible. Newer versions of Cisco
IMC are developed for SNS appliances after they are developed for UCS.
Note
In the download directory, check for any release notes or upgrade instructions.
The following steps describe how to upgrade the BIOS and Cisco IMC. This procedure may change when
