Juniper EX9214

Ensure that you have the following parts and tools available:
• ESD grounding strap
• Anstac bag or anstac mat
• Replacement SF module or cover panel for the slot
You must remove the Switch Fabric module (SF module) from an EX9200 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 li. You can remove the SF module and the Roung Engine module (RE module) as a unit, or
remove the RE module separately.
NOTE: Do not li the SF module by holding the ejector levers. The levers cannot support the
weight of the module. Liing the modules by the levers might bend the levers. Bent levers will
prevent the SF module from being properly seated in the chassis.
CAUTION: Before you replace an SF module, you must take the host subsystem oine.
If there is only one host subsystem, taking the host subsystem oine shuts down the
switch.
To remove an SF module:
1. Take the host subsystem oine. See Taking the Host Subsystem Oine in an EX9200 Switch .
2. Place the anstac bag or anstac mat on a at, stable surface.
3. Aach the ESD grounding strap to your bare wrist and connect the strap to the ESD point on the
chassis.
4. Rotate the ejector handles simultaneously counterclockwise to unseat the SF module.
5. Grasp the ejector handles and slide the SF module about halfway out of the chassis.
6. Place one hand underneath the SF module to support it, and slide it completely out of the chassis.
Place it on the anstac mat.
CAUTION: Do not stack hardware components on one another aer you remove
them. Place each component on an anstac mat resng on a stable, at surface.
7. If you are not replacing the SF module, install a cover panel over the empty slot.
