11.1 SBus Cards
The system board has three locations for SBus cards (see Figure 11-1).
Figure 11-1 SBus Slot Locations
Note – An SBus card extractor is included with all SBus card customer-
replaceable units (CRUs). You must remove the extractor from the replacement
card and install it on the defective card. Then use the SBus card extractor to
remove the defective card from the system unit.
If you need to remove an SBus card temporarily, and you do not have a
replacement card, try to find an extractor from some other source. If an
extractor is not available, place both thumbs beneath the corners of the card
where it connects to the system board. Carefully push upward with your
thumbs until the card disconnects from the system board.
11.1.1 Removing an SBus Card
1. Shut down and power off the system.
See Section 6.1, “Powering Off the System.”
2. Remove the cover and attach a wrist strap.
See Chapter 7, “Internal Access.”
3. Push the card retainers back from the edge of the SBus card.
See Figure 11-2.
