Switch Fabric (SF) Module in an EX8208 Switch on page 30
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 298.
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 216):
Take the SF module offline. See "Taking the SF Module Offline in an EX8208 Switch"
1.
on page 214.
Attach the electrostatic discharge (ESD) grounding strap to your bare wrist and
2.
connect the strap to the ESD point on the chassis.
Place the antistatic bag or antistatic mat on a flat, stable surface.
3.
Loosen the screws on each side of the SF module by turning them counterclockwise
4.
using the screwdriver until they are completely unseated.
Pull both the ejector levers outwards, away from the faceplate of the SF module, until
5.
they go no further. This action causes the SF module to slide out of the chassis slightly.
Grasping the ejector levers, pull the SF module to about halfway out.
6.
Taking care not to touch the leads, pins, or solder connections, place one hand
7.
underneath the SF module to support it and slide it out of the chassis completely.
