Juniper EX9214 - Removing an RE Module from an EX9200 Switch

Removing an RE Module from an EX9200 Switch
Before you begin to remove an RE module:
• Ensure you understand how to prevent electrostac discharge (ESD) damage. See Prevenon of
Electrostac Discharge Damage .
• Remove all the cables connected to the RE module.
CAUTION: Before you remove an RE module, you must take the host subsystem oine.
If there is only one RE module installed in the switch, taking the host subsystem oine
shuts down the switch.
CAUTION: If the RE module to be removed is funconing as the primary Roung
Engine, switch it to be the backup Roung Engine before removing it.
Ensure that you have the following parts and tools available:
• ESD grounding strap
• Phillips (+) screwdrivers, number 1 and 2
• Anstac bag or anstac mat
CAUTION: Do not li the Roung Engine module (RE module) by holding the ejector
levers. The levers cannot support the weight of the module. Liing the module by the
levers might bend the levers. Bent levers will prevent the RE module from being
properly seated in the chassis.
To remove an RE module from an EX9200 switch:
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 one of the ESD points on
the chassis.
4. Verify that the RE module LEDs are o.
5. Loosen the screws on each side of the RE module by turning them counterclockwise using the
screwdriver unl they are completely unseated.
6. Flip the ejector handles outward to unseat the RE module.
7. Grasp the RE module by the ejector handles and slide it about halfway out of the chassis.
