Removing an SF Module from an EX8208 Switch

You must remove the Switch Fabric (SF) module from the EX8208 switch if you need to replace the module or if you need to remove the switch components before moving the chassis without using a mechanical lift.

The SF module is always installed in the slot labeled SF.

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 Prevention of Electrostatic Discharge Damage.

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 Figure 1):

1. Take the SF module offline. See Taking the SF Module Offline in an EX8208 Switch.
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.
