8.8.1 Removing boards
Before removing boards, note Paragraph 8.3 Start-up procedure.
1. Detach the connectors that are plugged into the board you want to
remove.
2. Detach the two screws at the upper and lower end of the board front panel
(Figure 8-7). Because the board frame is tightly packed it is recommended
to loosen the screws of the adjacent boards. The adjacent board may be
partly pulled out to help the removal.
3. Pull the board carefully out from the slot.
