3.15 Removing the DSW42 Synchronous Communications
Option
The DSW42 synchronous communications option contains three components
that you must remove from the CPU module:
• A logic board (54-20640-01)
• An input/output cable (17-02942-01)
• An input/output module (70-28542-01)
To remove the DSW42 synchronous communications option from the BA42B
Enclosure, follow these steps:
1. Remove the enclosure cover (refer to Section 3.1).
2. Remove the upper and lower drive-mounting shelf combination (refer to
Section 3.11).
3. Remove the logic board, the input/output cable, and the input/output
module according to the procedures in the following subsections.
3.15.1 Removing the DSW42 Logic Board
Caution
Static electricity can damage integrated circuits. Wear a wrist strap
and place an antistatic mat under the system unit when working with
the internal parts of the system unit.
1. Press the latch on one of the standoff pillars (refer to Figure 3–38) and
push up the corner of the DSW42 logic board until the DSW42 logic board
is released.
Note
The standoff pillars contain two components: a push-button rivet
(12-35477-02) and a standoff (12-35477-03).
