Procedure
1 From the VMware Web site at https://my.vmware.com/web/vmware/downloads, download the
vCenter Server Appliance ISO image.
VMware-VCSA-all-version_number-build_number.iso
2 Confirm that the md5sum is correct.
See the VMware Web site topic Using MD5 Checksums at
http://www.vmware.com/download/md5.html.
3 Mount or extract the ISO image to the client machine from which you want to deploy, upgrade,
migrate, or restore the appliance.
Note ISO mounting or extracting software that does not allow more than eight directory levels, for
example, MagicISO Maker on Windows, is unsupported.
For Linux OS and Mac OS, Archive Manager is unsupported.
For Mac OS, you can use DiskImageMounter.
For Ubuntu 14.04, you can use Disk Image Mounter.
For SUSE 12 OS, you can use the terminal.
$ sudo mkdir mount_dir
$ sudo mount -o loop VMware-vCSA-all-version_number-build_number.iso mount_dir
What to do next
Open the readme.txt file and review the information about the other files and directories in the
vCenter Server Appliance ISO image.
Synchronizing Clocks on the vSphere Network
Verify that all components on the vSphere network have their clocks synchronized. If the clocks on the
machines in your vSphere network are not synchronized, SSL certificates, which are time-sensitive, might
not be recognized as valid in communications between network machines.
Unsynchronized clocks can result in authentication problems, which can cause the installation to fail or
prevent the vCenter Server Appliance vpxd service from starting.
Verify that any Windows host machine on which vCenter Server runs is synchronized with the Network
Time Server (NTP) server. See the Knowledge Base article http://kb.vmware.com/kb/1318.
To synchronize ESXi clocks with an NTP server, you can use the VMware Host Client. For information
about editing the time configuration of an ESXi host, see vSphere Single Host Management.
