Removing an SF Module from an EX8216 Switch

You must remove the Switch Fabric (SF) module from the EX8216 switch if you need to replace the module.

An EX8216 switch can have up to eight SF modules. All SF modules are installed in the rear of the chassis in the slots labeled SF7 through SF0. We recommend that all eight SF modules be installed in the chassis at all times.

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.

Use the handle provided on the faceplate of each SF module to lift the module.

Before you begin to remove an SF module:

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

To remove an SF module (see Figure 1):

  1. Before you remove an SF module, take it offline. See Taking the SF Module Offline in an EX8216 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 ejector levers outwards simultaneously, 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. Grasp the handle on the faceplate of the SF module with one hand and pull the SF module to about halfway out.
  7. Taking care not to touch the leads, pins, or solder connections, place one hand on the base of the SF module to support its weight, and slide it out of the chassis completely.
  8. Place the SF module in the antistatic bag or on the antistatic mat.
