One of the options for downloading an ISO image used by IP Office Web Manager is to download the ISO file from the primary server's DVD drive. To use this option for a virtual machine, you must first connect the virtual machine's DVD drive to the ISO file.

The VMware client supports the following options for connecting the virtual machine's DVD drive to a source. This section lists the different methods in order of preference based on speed and reliability:

• Connect to an ISO file on the client PCs hard disk – This method connects the virtual machine's DVD drive to an ISO file on the hard disk of the VMware client PC. The time to complete the upgrade depends on the speed between the vSphere host and the client PC. See Connect to an ISO File on the client PCs hard disk.

• Connect to the client PC DVD drive – This method connects the virtual machine's DVD drive to the DVD drive of the PC running the VMware client PC. The time to complete the upgrade depends on the speed between the vSphere host and the client PC. See Connect to the client PCs DVD drive.

• Connect to an ISO file in the virtual server datastore – This method connects the virtual machine's DVD drive to an ISO file previously uploaded to the virtual server datastore. For remote upgrades, this method is the most reliable. In addition, if multiple virtual machines use the same datastore, they can access the same ISO file. See Connect to an ISO File in the virtual server datastore.

• Connect to the VMware server's DVD drive – This method connects the virtual machine's DVD drive to a DVD drive on the VMware server PC. This method requires physical access to a DVD drive on the VMware server. See Connect to the host server's DVD drive.
