Overview

This document describes how to upgrade the firmware on a Cisco Secure Network Server (SNS) 3700 series appliance.


Note

We recommend that you perform graceful shutdown of the Cisco ISE services on the Cisco SNS appliance by using the halt CLI command before performing this upgrade. Forced shutdown or reload of the Cisco SNS server may corrupt Cisco ISE database.

Upgrade and Activate the Firmware

You must perform the following steps in the sequence given below to upgrade and activate the firmware:

Procedure

Step 1

Update BIOS Firmware

Step 2

Activate BIOS

Step 3

Update and Activate other Firmwares using HUU ISO

Note

If the BIOS firmware is not upgraded before the HUU ISO upgrade, then the BIOS will not be loaded properly and the boot options will not be displayed.

Update BIOS Firmware

Procedure

Step 1

Check the BIOS check box and click Update.

Step 2

Click Install BIOS Firmware Through Browser Client and select the BIOS image.

Step 3

Click Install Firmware.

BIOS is successfully uploaded as the backup version.

Activate BIOS

Procedure

Step 1

Choose Host Power > Power Off to manually power off the server.

Step 2

Check the BIOS check box.

Step 3

Click Activate.

Step 4

Choose the BIOS version and click Activate Firmware.

Step 5

Choose Host Power > Power On after activating the BIOS.

Update and Activate other Firmwares using HUU ISO

Procedure

Step 1

In the Cisco Integrated Management Controller toolbar, click Launch vKVM to launch the KVM console.

Step 2

In the KVM console, choose Virtual Media > vKVM-Mapped vDVD.

Step 3

Click Browse and browse for the HUU .iso file.

Step 4

Click Map Drive.

Step 5

Press F6 when prompted to open the Boot Menu window.

Step 6

In the Boot Menu window, choose UEFI: Cisco vKVM-Mapped vDVD2.00.

Step 7

If you choose the Reject option, the upgrade process is canceled and the host is rebooted.

Step 8

Click Update & Activate.

Step 9

In the Update & Activate All window, check the Power Cycle to Activate check box and click Update & Activate.

Note

 

BIOS upgrade is skipped during this step because BIOS is already upgraded to the latest version (see Update BIOS Firmware and Activate BIOS).

Step 10

The system is restarted after the firmware upgrade. Log in back to verify the upgraded firmware versions.

Verify the Firmware Version

Choose Admin > Firmware Management and verify the upgraded firmware versions in the Running Version column.

Choose Chassis > Summary and verify the firmware versions.


Note

Rollback of BMC and BIOS is not recommended while upgrading using the HUU ISO because it might cause compatibility issues.
