PCI Add-in Card Cable Installation

It maybe difficult to install a cable on the connector of a PCI add-in card configured atlocation A
in Figure24 due to interference from the power supply. If this occurs,it may be necessary to move
the power supplycage out of the way, install the PCI cable on the PCI add-in card, then replace the
power supply.
To connect a PCI cable to a PCI add-in card under these circumstances,follow these instructions:
1. Remove the two screws (B in Figure 24) holding the power supply cage in place.
2. Lift the back of the power supply and rotate it (C in Figure 24) so that it is placed outside of the
unit. (Thiscan be done without disconnecting the cable harness.)
3. Connect thecable to the PCI add-in card.
4. Replace the powersupply cage and secure it with the two screws previously removed.

Replacing the Back Up Battery
The lithiumbattery 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 weake n, it loses voltage, and the server settingsstored
in CMOS RAM in the RTC (for example, the date and time) may be wrong. Contactyour customer
servicerepresentative or dealer for a list of approved devices.
