Opening the Expansion Module Rear Panel
1. Separate the monitor and expansion module ( “Removing the Dual Battery in
Expansion Module” on page 53).
2. Remove the four screws securing the rear panel to the expansion module chassis.
3. Separate the rear panel from the chassis a few inches (keep any side panels with the
rear), then disconnect the expansion cable connector and the printer cable connector
from the circuit board (SCP or MSP board) in the rear panel.
4. Remove the rear panel with the side panels in place.
Note
For all sidestream CO

options (226, 227, 228, or 229) remove the front panel
( “Replacing the Expansion Module Front Panel” on page 81) and the extender
board “Replacing the Extender Board” on page 88 before proceeding with the
rear-panel removal.
Caution When disconnecting the expansion cable connector in the next step,
note that it has two plastic securing clips that must be separated from the
connector. These clips are fragile and should be handled carefully.
Note The rear panel is sealed to the chassis with rubber gaskets around the perimeter
of the rear panel. These gaskets can be reused when reassembling the expansion
module. Save these gaskets. Also, spacers might not be secured to the rear panel
and can fall out. As the unit is disassembled set aside the spacers for reuse
during reassembly.
