Removing an SF Module from a J-EX8216 Switch
You must remove the Switch Fabric (SF) module from the J-EX8216 switch if you need
to replace the module.
A J-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 you understand how to prevent ESD damage. See “Prevention of Electrostatic
Discharge Damage on J-EX Series Switches” on page 230.
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 74 on page 166):
1.
Before you remove an SF module, take it offline. See “Taking the SF Module Offline
in a J-EX8216 Switch” on page 164.
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.
