NOTE: Do not lift the SF module by holding the ejector levers. The levers cannot support the
weight of the module. Lifting the modules by the levers might bend the levers. Bent levers will
prevent the SF module from being properly seated in the chassis.
Before you begin to remove an SF module:
Ensure you understand how to prevent ESD damage. See
on page 381.
Ensure that you have the following parts and tools available to remove an SF module:
Electrostatic discharge (ESD) grounding strap
Phillips (+) screwdriver, number 2
Antistatic bag or antistatic mat
Replacement SF module or cover panel for the slot
To remove an SF module (see
1. Take the SF module offline. See
2. Attach the electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to
the ESD point on the chassis.
3. Place the antistatic bag or antistatic mat on a flat, stable surface.
4. Loosen the screws on each side of the SF module by turning them counterclockwise using the
screwdriver until they are completely unseated.
5. Pull both the ejector levers outwards, away from the faceplate of the SF module, until they go no
further. This action causes the SF module to slide out of the chassis slightly.
6. Grasping the ejector levers, pull the SF module to about halfway out.
7. Taking care not to touch the leads, pins, or solder connections, place one hand underneath the SF
module to support it and slide it out of the chassis completely.
8. Place the SF module in the antistatic bag or on the antistatic mat.
9. If you are not replacing the SF module, install the cover panel over the empty slot by tightening the
screws on each side of the cover panel with the screwdriver.
