Back Up Your System
Before performing the server upgrade, protect yourself by backing up all data and the server OS. In the event
of interruptions (for example, power failure or interference), you may need to resume operation in the old
configuration before upgrading the server.
Back up your data in accordance with local procedures.
Always keep a backup copy of the current OS available for emergency use. The OS was provided on CD with
the server. You can obtain a copy from your HP-Information Resource Center (ITRC).
Removing Server Components
WARNING Ensure that the system is powered off and all power sources have been disconnected
from the server before removing or replacing server components.
Voltages are present at various locations within the server whenever an ac power
source is connected. This voltage is present even when the main power switch is in
the off position.
