Removing an RE Module from an EX9200 Switch
CAUTION: Do not lift the Routing Engine module (RE module) by holding the
ejector levers. The levers cannot support the weight of the module. Lifting
the module by the levers might bend the levers. Bent levers will prevent the
RE module from being properly seated in the chassis.
Before you begin to remove an RE module:
•
Ensure you understand how to prevent electrostatic discharge (ESD) damage. See
“Prevention of Electrostatic Discharge Damage” on page 351 .
• Remove all the cables connected to the RE module.
CAUTION: Before you remove an RE module, you must take the host
subsystem offline. If there is only one RE module installed in the switch, taking
the host subsystem offline shuts down the switch.
CAUTION: If the RE module to be removed is functioning as the master
Routing Engine, switch it to be the backup Routing Engine before removing
it.
Ensure that you have the following parts and tools available:
• ESD grounding strap
•
Phillips (+) screwdrivers, number 1 and 2
•
Antistatic bag or antistatic mat
To remove an RE module from an EX9200 switch:
1.
Take the host subsystem offline. See “Taking the Host Subsystem Offline in an EX9200
Switch” on page 226 .
2.
Place the antistatic bag or antistatic mat on a flat, stable surface.
3.
Attach 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 off.
5.
Loosen the screws on each side of the RE module by turning them counterclockwise
using the screwdriver until they are completely unseated.
6.
Flip the ejector handles outward to unseat the RE module.
