▼ To Remove the System Controller
Caution – The system controller can be hot. To avoid injury, handle it carefully.
1. Perform the procedures described in “Common Procedures for Parts
Replacement” on page 67 .
2. Locate the system controller card.
See Appendix A for an illustration of the servers FRUs that shows the system
controller card.
3. Push down on the ejector levers on each side of the system controller until the

Ejecting and Removing the System Controller Card
4. Grasp the top corners of the card and pull it out of the socket.
5. Place the system controller card on an antistatic mat.
6. Remove the system configuration PROM (
FIGURE 4-10
) from the system controller
and place it on an antistatic mat.
The system controller contains the persistent storage for the host ID and Ethernet
MAC addresses of the system, as well as the ALOM configuration including the IP
addresses and ALOM user accounts, if configured. This information will be lost
unless the system configuration PROM is removed and installed in the replacement
system controller. The PROM does not hold the fault data, and this data will no
longer be accessible when the system controller is replaced.
