IBM Coax/Twinax Expansion Board
Removal
ATTENTION
To prevent electrostatic damage to electronic components, wear a properly grounded static wrist strap when handling
circuit boards, the shuttle frame assembly, and any other electronic component.
1. Prepare the printer for maintenance (page 313).
2. Cabinet Model: Remove the paper guide assembly (page 348).
Pedestal Model: Remove the top cover assembly (page 327).
3. Remove the screw securing the coax/twinax I/O plate to the rear of the card cage. (See Figure 48, page 421, item 4.)
4. Carefully work the PCI-CT board upward and out of the expansion slot on the controller board. (See Figure 48, page 421,
item 1.)
Installation
1. Reverse the steps of the removal procedure.
2. Return the printer to normal operation (page 314).
IMPORTANT
If the printer uses the twinax interface and has a power stacker, install the Smart-T cable extension between the
twinax interface connector on the PCI-CT board and the twinax auto-termination (Smart-T) cable. (See Figure 51 on
page 427.) The Smart-T cable extension cable permits the twinax auto-termination cable to clear the stacker elevator.
