May I use Terminal Services, Virtual Network Computing (VNC), or Integrated Lights Out (ILO) to install/upgrade the utility?
Do not use Terminal Services to install/upgrade the utility. To eliminate remote access to the server during the installation/upgrade, Cisco recommends that you disable Terminal Services before the utility installation/upgrade and reboot the server. You must enable Terminal Services after the installation/upgrade. If you want to use Virtual Network Computing (VNC) to remotely install supported applications, see Table 1 to obtain the latest version of the VNC document. Caution If you have installed VNC but do not plan to use it to perform the installation, disable it to prevent remote access to the server. If you do not disable VNC and a user/administrator accesses the server during the installation, the utility installation will fail. Do not use Integrated Lights Out (ILO) to install or upgrade the utility. Cisco supports ILO for remote management and remote configuration tasks only.
