Removing an SRE Module from an EX8208 Switch

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

Caution: Do not lift the SRE module by holding the ejector levers. The levers cannot support the weight of the module. Lifting the module by the levers might bend the levers. Bent levers will prevent the SRE module from being properly seated in the chassis.

Before you begin to remove an SRE 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 SRE module:

• Electrostatic discharge (ESD) grounding strap
• Phillips (+) screwdriver, number 2
• Antistatic bag or antistatic mat
• Replacement SRE module or cover panel for the SRE module slot

To remove an SRE module from an EX8208 switch (see Figure 1):

1. Take the SRE module offline. See Taking the SRE Module Offline in an EX8208 Switch.
2. Attach the antistatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points 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 SRE 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 SRE module, until they go no further. This action causes the SRE module to slide out of the chassis slightly.
6. Grasp the ejector levers and pull the SRE module out to about halfway.
7. Taking care not to touch the leads, pins, or solder connections, place one hand underneath the SRE module to support it and slide it completely out of the chassis.
8. Place the SRE module in the antistatic bag or on the antistatic mat.
9. If you are not replacing the SRE module, place the cover panel over the empty slot, insert the screws through the holes on each side of the cover panel, and tighten the screws with the screwdriver.
