Introduction
This document describes the process to reinstall the Cisco Secure Network Analytics (SNA) software remotely on UCS hardware models.
Prerequisites
Requirements
Cisco recommends that you have knowledge of these topics:
- Cisco Secure Network Analytics
- Cisco Integrated Management Controller (CIMC)
Components Used
The information in this document is based on these components:
- Cisco Flow Sensor 4240 (M5 Hardware)
- CIMC version 4.1(1d)
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.
Procedure
The suggested procedure is to reinstall the SNA Operating System (OS) remotely via the Kernel-based Virtual Machine (KVM) console from the CIMC. To accomplish this, proceed as follows:
Step 1. Download the ISO file
An ISO file for the applicable appliance model is required to reinstall the SNA OS. To download the required ISO file:
1. Go to Cisco Software Central, https://software.cisco.com.
2. In the Download and Upgrade section, select Software Download.
3. Type Secure Network Analytics in the Select a Product field. Press Enter.
4. Select the applicable virtual appliance model.
Note: The ISO file is located only in the virtual edition of the appliance. For example, if you need to reinstall the SNA OS of a Flow Collector 4210 appliance, you must select Virtual Flow Collector.
5. Under Select a Software Type, select Secure Network Analytics System Software, and then select the desired Software Version.
6. Locate the ISO file required for the virtual appliance model.
