Upgrade Tasks
Upgrade tasks depend on whether the server is configured for simplex or duplex operation. The following 
information provides the high-level steps required to perform the upgrade. The actual upgrade procedures are 
provided below.
Simplex Configuration Upgrade
1. Back up your data
2. Shutdown the server (disconnect ac power)
3. Remove server components
4. Replace SCSI backplane
5. Install server components
6. Verify the upgrade installation
Duplex Configuration Upgrade
1. Back up your data
2. Shutdown the server (disconnect ac power)
3. Remove server components
4. Remove the SCSI duplex board
5. Replace SCSI backplane
6. Install the replacement SCSI duplex board
7. Install server components
8. Verify the upgrade installation
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.
