Step 12. Disconnect the external SSA cables (if present) from all four bypass cards. To
prevent damage to the SSA connector screws, ensure that you use the
special screwdriver (SSA tool, part 32H7059) to unscrew them. The
screwdriver is supplied with the 7133.
Step 13. Attention: The four bypass cards might not all have the same jumper
settings. It is important, therefore, that they be reinstalled into the correct
positions.
Make a note of the positions of the bypass cards before you remove them.
Attach labels if necessary.
Step 14. Remove the four bypass cards (see “Bypass (SNBC) Cards” on page 201).
