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
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.
See “Handling and Storing Line Cards in EX9200 Switches” on page 237 .
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.
CAUTION: The weight of line cards in EX9200 switches is in the range
14–19.4 lb (6.6–8.8 kg). Be prepared to support the full weight as you
slide the line card into the chassis.
7.
Place one hand around the faceplate of the line card and the other hand under the
line card to support it. Taking care not to touch line card components, pins, leads, or
solder connections, gently slide the line card completely out of the chassis and place
it in an antistatic bag or on its own antistatic mat placed on a flat, stable surface.
