Release Notes for Cisco CDA Visual Quality Experience Application Release 3.10
Installing VQE Release 3.10 Software
An ISO clean installation installs a complete new set of VQE, Linux, Quagga, and other files. An ISO
clean installation does not backup or restore your current VQE 3.X configurations. An ISO clean
installation reformats the hard drive and reinstalls the operating system and other packages, such as the
VQE software. All old configurations are removed.
Before performing an ISO clean installation, perform the following tasks:
1. If you do not have an ISO software installation CD with VQE Release 3.2 software, see
Downloading VQE Software from Cisco.com, page 11.
2. Backing Up VQE Release 3.X Files Before Upgrading or Installing Software, page 12
Note ISO clean installations must be performed using the CDE serial port (not the CDE video and keyboard
ports). For these installations, the serial port connection can be through a terminal server or through a
directly connected PC.
For terminal emulation software configuration, see “Configuring Terminal Emulation Software” in
Chapter 2 of the Cisco CDA Visual Quality Experience Application User Guide, Release 3.10.
To perform an ISO clean installation to install VQE Release 3.10 on an earlier VQE Release 3.X system,
do the following:
Caution An ISO clean installation will format the hard disk on the CDE111/ CDE250 2V0. Formatting causes all
data on the hard disk to be erased.
Be sure to backup configuration files as described “Backing Up VQE Release 3.X Files Before
Upgrading or Installing Software” section on page 12. With this backup of the configuration files, you
will have the earlier VQE 3.X configuration files available for reference if you need them after the ISO
clean installation is complete.
Step 1 Insert the ISO software installation CD in the CDE111/ CDE250 2V0 CD/DVD Combo drive.
Step 2 Power on or power cycle the CDE111/ CDE250 2V0.
When the VQE installation software runs, the boot: prompt is displayed.
Step 3 Type clean if you are installing a CDE111 or type clean250 if you are installing a CDE250 2V0 and
press Enter. For example:
boot: clean
Note If you enter invalid input at the boot: prompt, the installer displays “Could not find kernel image” and
your input.
This message is harmless. Enter correct input (clean) and proceed with the installation.
When you select an ISO clean installation and the installation begins, no further user input is required
or allowed until the initial configuration of the CDE111/ CDE250 2V0 server.
An ISO clean installation does the following:
1. Formats the hard disk.
2. Installs the Linux operating system and all packages.
