PCI Add-in Card Cable Installation
It may be difficult to install a cable on the connector of a PCI add-in card configured at location A
in Figure 24 due to interference from the power supply. If this occurs, it may be necessary to move
the power supply cage out of the way, install the PCI cable on the PCI add-in card, then replace the
power supply.

Replacing the Back Up Battery
The lithium battery on the server board powers the real time clock (RTC) for up to 10 years in the
absence of power. When the battery starts to weaken, it loses voltage, and the server settings stored
in CMOS RAM in the RTC (for example, the date and time) may be wrong. Contact your customer
service representative or dealer for a list of approved devices.
