Prerequisites and Restrictions for a Remote ISO Software Installation

Before proceeding, read and understand these sections on ISO clean and ISO full upgrade installations:

• ISO Clean Installation, page 10

• ISO Full Upgrade, page 10

To perform an ISO software installation from a remote location, the following prerequisites and

requirements must be met for the CDE111/ CDE250 2V0 server on which the software will be installed:

• CDE111/ CDE250 2V0 server must have a factory-installed flash drive. Only CDE111 model

numbers CDE111-2-146TXA-K9 and CDE111-2-146TXD-K9 have a factory-installed flash drive.

If the CDE111/ CDE250 2V0 does not have the needed second drive (for example, flash drive), the

installation software displays this error message:

ERROR: No second disk detected on CDE-111...

This could indicate a hardware failure.

Please contact Cisco Technical Support.

• CDE111/ CDE250 2V0 servers must be running and have a functioning hard disk drive and flash

drive.

• Remote access to the CDE111/ CDE250 2V0 servers must be through the server serial port.

Typically, remote access is through a terminal server connected to a serial port on the front or back

of the Cisco CDE111/ CDE250 2V0. 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.

• There must be a mechanism to remotely power cycle the CDE111/ CDE250 2V0 servers. This

mechanism is needed to make sure that the technician can restart the installation process should the

server become irresponsive during the installation.

• VQE software currently installed on the CDE111 servers must be for VQE Release 3.3.1 or a later.

VQE software currently installed on the CDE250 2V0 servers must be for VQE Release 3.10. If the

CDE does not have the needed VQE software release, the installation software displays an error

message. For example:

ERROR: Remote ISO installation is not supported for Versions below 3.3

ISO Image Version : Cisco VQE Server Release 3.2.2 (Build 7)

Because the remote installation software is not present in VQE releases earlier than Release 3.3.1, the

following restrictions apply to an ISO clean or ISO full upgrade installation from a remote location:

• If the software currently installed on the CDE111 servers is for a VQE release earlier than

Release

3.3.1, an ISO clean or ISO full upgrade installation from a remote location is not possible.

• Downgrade using an ISO clean installation from VQE Release 3.3.X to a version of VQE earlier

than Release 3.3.1 is not possible.

However, you can remotely perform an ISO clean or ISO full upgrade installation to upgrade from VQE

Release 3.3.X or 3.10.X to a later VQE release. For example, you can use a ISO clean or ISO full upgrade

installation to upgrade from Release 3.3.2 or Release 3.10.

You can remotely perform an ISO clean installation to downgrade from VQE Release 3.3.X or 3.10.X

to any earlier VQE 3.3.X or 3.10.X release. For example, a remote ISO clean installation from Release

3.10 to Release 3.3.2 is allowed. Be aware that using an ISO clean installation always removes all old

configurations. An ISO full downgrade installation is not currently supported.
