Replacement
To replace an SBAR assembly:
1. Remove the replacement SBAR assembly from its protective
anti-static bag.
2. Inspect the printed wiring assembly (PWA) side of the SBAR
assembly for bent or broken connector pins that may have been
damaged during shipping. If any pins are damaged, obtain a new
assembly.
3. Orient the SBAR assembly ( Figure 78 ). Insert the assembly into
the director chassis guide, then push the assembly toward the
backplane to engage the connector pins. Verify the assembly is
flush and even with the other SBAR assembly in the director.
4. Close both handles.
5. Disconnect the ESD wrist strap from the director chassis and your
wrist.
