• Ensure that you know how to handle and store the line card. See
Ensure that you have the following parts and tools available to remove a line card from an EX9200
switch chassis:
• ESD grounding strap
• An antistatic bag or an antistatic mat
• Replacement line card or a cover panel and its captive screws to cover the empty slot
EX9200 switches have field-replaceable unit (FRU) line cards that can be installed in the line card slots
on the front of the switch chassis. The line cards are hot-insertable and hot-removable: You can remove
and replace them without powering off the switch or disrupting switch functions. However, we
recommend that you take them offline before removing them.
To remove a line card from an EX9200 switch:
1. Place the antistatic bag or antistatic mat on a flat, stable surface.
2. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the
switch chassis.
3. Label the cables connected to each port on the line card so you can reconnect the cables to the
correct ports.
4. Take the line card offline by issuing the following CLI command:
user@switch> request chassis fpc slot slot-number offline
5. Rotate the ejector handles simultaneously counterclockwise to unseat the line card.
6. Grasp the handles, and gently slide the line card halfway out of the chassis.
Handling and Storing Line Cards
See
CAUTION: Do not lift the line card by holding the ejector levers on the faceplate or
the edge connectors. The levers cannot support the weight of the line card. Lifting the
line cards by the levers might bend them. Bent levers prevent the line cards from being
properly seated in the chassis.
CAUTION: Do not stack line cards on top of one another or on top of any other
component. Place each line card separately in the antistatic bag or on the antistatic
mat placed on a flat, stable surface.
