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 on EX Series Switches” on page 292
.

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 86 on page 218):

1.

Take the SF module offline. See “Taking the SF Module Offline in an EX8208 Switch”
on page 216
.

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.
