Chrome 31 Patch
This is a generic patch for CE340 release 1.2.0.x to update the chrome 31 version.
Note The Chrome patch should be applied after the OS patch installation.
For example, if you are going to upgrade from release 1.2 to release 22.214.171.124, follow this order: 1.2 -> 126.96.36.199 -> CE340_Chrome-31_patch-0.6.tar.gz.
Follow these steps to install the Chrome 31 patch:
Step 1 Log in to the Cisco Edge 340 Series system as root with terminal through SSH or Desktop.
Step 2 Copy or download the patch file to the Cisco Edge 340 Series filesystem.
Step 3 Follow these steps to install the patch:
a. Use the following command to uncompress the patch, for example, to the
# tar xvzf $folder/ce340_Chrome-31_patch.tar.gz -C /tmp/
b. Go to the target folder where you uncompressed the patch and run the
install.sh file to install the patch management tool:
# cd /tmp/ce340_Chrome-31_patch

Upgrading to a New Software Release
The Cisco Edge 340 series supports the following installation and upgrade methods:
Note After you upgrade CE340 from release 1.0.5 to release 1.2, the manual mode will be switched to auto mode in the network settings, and the manually configured network settings will be lost, even if you choose “keep user data” during the upgrade. The workaround is to use DHCP server to assign the IP address.
USB Mode Installation and Upgrade
The Cisco Edge 340 Series software releases a self-extract installer. The file name is Cisco-Edge- version -i386-DVD.bin. It is an executive file that helps you to perform the installation automatically. When you execute the self-extract installer, the installation-related files are extracted to the hard drive of the Cisco Edge 340 Series, and a livecd is created in the internal USB. The system then boots from the internal USB (also known as the factory mode) and performs the installation automatically.
If the internal USB has already been created as a livecd, you can press the factory mode pinhole on the front panel of the Cisco Edge 340 Series to enter the factory mode and perform the installation procedure automatically.
Note Usually, the internal USB is created as a livecd in the factory. Executing the self-extract installer will overwrite the original livecd and create a new one.
Before you execute the self-extractor installer, perform the following steps to make sure that the installation will be successful.
Step 1 Locate your target self-extract installer (Cisco-Edge-xxx-i386-DVD.bin).
Step 2 Make sure that the livecd-tools has been installed using the following command:
Step 3 Make sure there is at least 1.5G free space on HOME or ROOT partition. If you execute the self-extractor installer without enough space on the partition, you will see the either of the following message displayed: No enough disk free space or Failed to extract ISO!
- Use the following command to check the available space on the HOME partition:
- Use the following command to check the available space on the ROOT partition:
Step 4 If you want to use an external USB as the target USB, make sure the first partition of the USB has at least 1.5G free space. The ext4 format is recommended, and ext3/fat32 format is also supported.
Step 5 Make sure the self-extract-installer (Cisco-Edge-xxx-i386-DVD.bin) has the executable attribute. Set the attribute with the following command:
chmod a+x /path/to/ Cisco-Edge-xxx-i386-DVD.bin
Step 6 Make sure no other installation or upgrade process is ongoing.
Note If another installation or upgrade process is ongoing, and you execute the self-extractor installer, you will see the following message displayed: an install process is ongoing. You can wait until the ongoing upgrade process is finished, or you can reboot the system, and then execute the self-extractor installer again.
Note When you select the internal USB as target livecd, if power failure happens during the process of command execution, the old livecd on the internal USB will be wiped. You have to rebuild a livecd disk on the internal USB.
You can use the Cisco-Edge- version -i386-DVD.bin command with different parameters to implement installation or upgrade, print help, or create livecd only. In the command, version indicates the image version, which will be 1.2 for this release. For detailed instructions of installation and upgrade for this release, see Cisco Edge 340 Series Software Configuration Guide, Release 1.2.
For the installation and upgrade of the releases other than 1.2, refer to the software configuration guide of corresponding releases.
Note When you use this method to install or upgrade the system, make sure there is 1.5G free space at least.
1. To select the internal USB as a livecd disk and boot into factory mode to finish the installation automatically, use the following command:
2. To print help and then exit, use the following command:
3. To create livecd only, without entering factory mode nor executing the system installation program, use the following command:
Cisco-Edge-1.x-i386-DVD.bin -t|--target <dev>
<dev> is the full path of the target u-disk into which the livecd will be burned, for example, /dev/sdb1.
4. To wipe the home partition before the system is installed, use the following command:
Note When the home partition is wiped, user data will be lost.
Installation With External USB
Follow these steps to upgrade your Cisco Edge 340 Series to software release 1.2 with an external USB:
Step 1 Get a Fedora PC.
Step 2 Attach a USB flash drive to the PC.
Step 3 Download Cisco-Edge-1.2-i386-DVD.bin to the PC.
Step 4 Execute the following commands in shell:
su -c "chmod +x Cisco-Edge-1.2-i386-DVD.bin"
su -c "./Cisco-Edge-1.2-i386-DVD.bin -t /dev/sdb1"
Replace sdb1 in the above command with your own USB and wait until the command is completed.
Step 5 Detach the USB flash drive from the PC and attach it to your Cisco Edge 340 Series device.
Step 6 Boot your Cisco Edge 340 Series from the USB.
Step 7 Wait for the installation to complete and then reboot the device.
Installation With Internal USB of the Cisco Edge 340
Follow these steps to upgrade your Cisco Edge 340 Series to software release 1.2 with the internal USB:
Step 1 Download Cisco-Edge-1.2-i386-DVD.bin to the SSD of your Cisco Edge 340 Series device.
Step 2 Execute the following commands in shell:
su -c "chmod +x Cisco-Edge-1.2-i386-DVD.bin"
su -c "./Cisco-Edge-1.2-i386-DVD.bin"
Step 3 Wait for the installation to complete and then reboot the device.
Remote Upgrade From the Web GUI
You can perform a remote upgrade for the Cisco Edge 340 Series using the web GUI if you have the address to download the self-extract installer. When you choose to perform the remote upgrade, the system will automatically download the self-extract-installer from the URL that you provide and execute the self-extract-installer to finish the installation.
BIOS upgrade can only be performed by manually installing the package and executing the commands in the Linux environment. BIOS is a critical part of the system, and there is no software recovery method if it crashes. To ensure successful BIOS upgrade, make sure that the external power supply is always connected, and do not perform any power cycle action during the upgrade process.
Recovering from a Software Failure
For recovery procedures, see the “Troubleshooting” chapter in the Cisco Edge 340 Series Software Configuration Guide.
