Figure 4-7 SSB removal (part 3)
1. Once you have taken out the SSB, remove the shieldings
[2]. Sometimes it is necessary to unsolder some solder
tags before doing this [1].
2. Replace the SSB module in the SIMM-connector in reverse
order.
Notes:
• For better access to the SSB, it is possible to order an
"extension board," which is part number 9965 000 05769.
• If it is necessary for measurements, you can put the LSP in
"service position 2" (as described above).
4.4 Assembly / Board Removal
Sometimes, it may be necessary to swap a complete assembly
or Circuit Board Assembly (CBA). This procedure is explained
below.

2. Pull the complete assembly back and upwards (the
