Release Notes for Cisco IEC6400 Edge Compute Appliance, Release 1.2.0

This document provides information about the Ultra-Reliable Wireless Backhaul (URWB) mode of operation for the Cisco IEC6400 Edge Compute Appliance. IEC6400 acts as the gateway in a URWB network, and it uses the URWB technology with Cisco UCS C220 M6 Rack Server.

This document describes the new features, limitations, and troubleshooting steps, in addition to providing recommended configurations, caveats, and information on how to obtain support and documentation.

Ease of Use

Secure Storage Encryption

This feature provides improved security through the Cisco TAM library.

New hardware features

There are no new hardware features in this release.

Change in behavior

There are no behavior changes in this release.

Secure storage encryption

This release introduces Secure Storage encryption, which provides improved security through the Cisco TAM library.

Important Upgrade Requirement

●     Before upgrading to version 1.2.0 from an older version, a special image must be installed to initialize the secure storage on the device.

●     Upgrading to 1.2.0 without first installing this special image will cause the upgrade to fail.

Obtaining the Special Image

To obtain the image, contact Cisco TAC and provide the following information for each device:

●     IEC6400 serial number

●     IEC6400 Mesh ID


Note: While the secure storage programming data is unique to each IEC6400 unit, information for multiple devices can be combined into a single TAM image for convenience.

Key Considerations

●     This special image installation is a one-time process for the device's lifetime. It is only required again if a factory data wipe is performed after downgrading to a pre-1.2.0 version.

●     Downgrading to software versions older than 1.2.0 is not recommended.

Upgrade Process Flow

Step 1.         Get TAM upgrade image and install it on the IEC6400

1.     Identify the IEC6400 units

2.     Contact the Cisco TAC with the device info to obtain the TAM upgrade image.

3.     Upload this image to the IEC6400 unit by performing a regular image upgrade. You can use methods such as TFTP or USB.

Step 2.         Install IEC6400 software 1.2.0

1.     Once the TAM upgrade image is installed, proceed with the standard installation of IEC6400 software version 1.2.0.

Note: For more information on upgrade, see Upgrade Firmware for Cisco IEC6400 Edge Compute Appliance document.
