2 Disconnect the BCM system from the AC power outlet.
3 Attach one end of the grounding strap to your wrist and the other end to a grounded metal
surface.
4 Remove the top cover of the main unit (see “Removing the main unit top cover” on page 244).
5 Disconnect any connectors from the front of the base function tray.
6 Partially remove the base function tray from the main unit (See “Removing the base function
tray” on page 234). Do not exert force on the DS30 cables and connectors. Ensure you do not
pinch, stretch, or damage any cables.

stretch, or damage any cables (see “Removing the base function tray” on page 234). Place the

Warning: Protect the hardware components against damage from electrostatic discharge.
Always wear a grounded wrist strap before you handle components. Always place the
components in a static-free container.
