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: DonotlifttheSFmodulebyholdingtheejectorlevers.Theleverscannotsupport
the weightof the module. Lifting the modulesbythe leversmight bend the levers. Bent
levers will prevent the SF modulefrom being properlyseated 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. TaketheSFmoduleoffline.See“Takingthe SFModuleOfflineinan EX8208Switch”
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 eachside of theSF moduleby turning themcounterclockwise
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.
