Replacing the iLO MP Card Battery
A battery is located on the underside of the iLO MP card, with a design lifetime of ten years.
Access the three-volt CR2032 battery for replacement only when the iLO MP card is removed
from the server.
CAUTION: Observe all ESD safety precautions while performing this procedure. Failure to
follow ESD safety precautions can result in damage to the server.
NOTE: There are two batteries in the server: the iLO MP card battery and the system battery.
See the parts list for the iLO MP card battery part number.
To replace the battery, perform these steps:
1. After removing the iLO MP card from the server chassis, locate the battery on the underside
of the card.
CAUTION: Do not overstress the battery retaining clip. This clip is easily broken. Lift the
battery just high enough to clear the battery holder. Failure to heed this warning can result
in damage to the clip.
2. Lift up on the battery retaining clip and push on the back of the battery with a flathead
screwdriver to remove it from its holder. Remove the battery.
WARNING! Lithium batteries can explode if mistreated. Do not recharge, disassemble, or
dispose of batteries in a fire. When discharged, do not throw batteries away, collect them
as small chemical waste. Failure to observe this warning can result in personal injury or
damage to equipment.
3. Lift up on the retaining clip and slide the replacement battery into its holder. Make sure the
positive side of the battery faces up.
Installing the iLO MP Card
CAUTION: Observe all ESD safety precautions while performing this procedure. Failure to
follow ESD safety precautions can result in damage to the server.
To install the iLO MP card, follow these steps:
1. Position the iLO MP card onto the three screws with the edge connectors aligned with the
corresponding cutouts on the rear section of the chassis (Figure 6-27).
2. Fasten the two screws securing the DB-25 connector to the chassis rear panel.
3. Reconnect the low-profile ribbon connector to the system board.
4. Insert and tighten the two screws that secure the iLO MP card to the three standoffs on the
system board.
5. Install the processor airflow guide. See “Installing the Processor Airflow Guide” (page 176).
NOTE: If you are installing a replacement iLO MP card, attach the label with the new
Media Access Control address (MAC address) to the rear of the server. A complete description
of the iLO MP is provided in the HP Integrity and HP 9000 iLO Operations Guide.
Removing and Replacing a Single-Core System Processor
The server can include one or two processors. The processors are located on the system board
and are accessible after removing the top cover and airflow guides. Processor 0 (CPU 0) is located
closer to the chassis side panel and processor 1 (CPU 1) is located closer to the DIMM sockets.
