Removing The Sbus Card; Figure 11-2 Opening The Sbus Card Retainers - Sun Microsystems SPARCstation 4 110 Service Manual

An SBus card extractor is included with all SBus card 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.
