Installing a PCI Expansion Board
Guidelines for installing PCI expansion boards
The system supports up to two expansion boards at a time. Use only HP supported expansion boards that meet
the following specifications:
• PCI or PCI-X compliant
• Connector: 32 or 64 bits wide, 3.3 V
• Speed
• PCI board speed: 66 MHz
• PCI-X board speed: 100 or 133 MHz
• Form factor: low profile or standard height/full-length boards
• PCI Express x8 compliant (available only when the optional PCI Express riser board is installed)
To install a PCI expansion board:
1. Install the PCI expansion board following the procedures described in the “To install the SCSI controller
board:” section.
2. Connect the necessary cable(s) to the board.
Refer to the documentation that came with the board.
3. Perform the post-installation procedure.
System battery
The HP ProLiant server uses nonvolatile memory that requires a battery to retain system information when power
is removed. The battery, a 3 V 200-mAh internal lithium battery, is located on the system board (BT1).
Figure 49 System battery
If the server no longer automatically displays the correct date and time, the system battery that provides power to
the real-time clock may need to be replaced. Under normal use, battery life is 5 to 10 years.
WARNING! Note the following reminders when replacing the system battery:
•
Replace the battery with the same type as the battery recommended by HP. Use of another battery may present a risk of
fire or explosion.
• A risk of fire and chemical burn exists if the battery is not handled properly. Do not disassemble, crush, puncture, or
short external contacts, or expose the battery to temperatures higher than 60°C (140°F).
• Do not dispose of used battery in water or fire. Dispose of used batteries according to manufacturer's instructions.
CAUTION: Loss of BIOS settings occurs when the battery is removed. BIOS settings must be reconfigured
whenever the battery is replaced.
