Installing a Line Card in an EX8200 Switch

EX8200 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.

Before you begin installing a line card in the switch:

• Ensure that you have taken the necessary precautions to prevent Electrostatic discharge (ESD) damage (see Prevention of Electrostatic Discharge Damage on EX Series Switches).
• If there are any transceivers installed in the line card, remove them before you install the line card. For instructions on removing transceivers, see Removing a Transceiver from an EX Series Switch.
• Ensure that you know how to handle and store the line card (see Handling and Storing Line Cards in EX8200 Switches).
• Ensure the switch has sufficient power to power the line card while maintaining its N+1 or N+N power configuration:
  • To determine the power requirements of the line card, see Power Requirements for EX8208 Switch Components or Power Requirements for EX8216 Switch Components.
  • To determine whether the switch has enough power available for the line card, use the show chassis power-budget-statistics command if your switch is running Junos OS Release 10.2 or later. If your switch is running Junos OS Release 10.1 or earlier, see Calculating Power Requirements for an EX8208 Switch or Calculating Power Requirements for an EX8216 Switch to calculate the available power.

Ensure that you have the following parts and tools available to install a line card in the switch:

• ESD grounding strap
• Phillips (+) screwdriver, number 2

To install a line card in the switch:

1. Attach the ESD grounding strap to your bare wrist and connect the strap to the ESD point on the switch chassis (see Figure 1). The ESD point is at the same location on EX8208 and EX8216 switches.

   Figure 1: Location of the ESD Point on an EX8200 Switch Chassis

   

2. If the line card slot has a cover panel on it, use the screwdriver to remove the captive screws on each side of the cover panel. Save the cover panel and the screws for later use.

   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 card by the levers might bend them. Bent levers prevent line cards from being properly seated in the chassis.

3. Taking care not to touch line card components, pins, leads, or solder connections, remove the line card from its bag.
4. Grasp the ejector levers on the faceplate of the line card and pull them outward until they are fully open. The closed and the open positions of the shorter ejector levers are not as markedly distinguishable as those of the longer ones (see Figure 2).

   Figure 2: Closed and Open Positions of the 2-in. Ejector Lever

   

5. Place one hand around the faceplate of the line card and the other hand under the line card to support it.

   Caution: The line cards in EX8200 switches weigh more than 10 lb (4.5 kg). Be prepared to support the full weight as you slide the line card into the chassis. Before you slide the line card into the slot on the switch chassis, ensure the line card is aligned correctly. Misalignment might cause the pins to bend, making the line card unusable.

6. Lift the line card, and position it in the chassis with the faceplate facing you and the sides of the line card aligned with the guides in the line card slot on the switch chassis.
7. Make sure the levers stay in the open position (see Figure 2) and gently slide the line card fully into the slot using both hands.

   Note: You might need to lift the line card slightly to seat it correctly in the slot.

8. Grasp the ejector levers on the line card and push them inward simultaneously until the line card is fully seated (see Figure 3 and Figure 4).

9. Tighten the captive screws on the faceplate of the line card by using the screwdriver.
10. Verify that the ON LED starts blinking in green. When the ON LED is lit steadily, the line card is ready for use. If the ON LED does not blink or is not lit steadily, see Troubleshooting Line Card Installation on EX8200 Switches.

    Caution: After the ON LED is lit steadily, wait for at least 30 seconds before installing another line card or removing a line card.

You can verify that the line card is functioning correctly by issuing the show chassis fpc and show chassis fpc pic-status commands.

Note: If you have a Juniper J-Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/csc/management/updateinstallbase.jsp. Failure to do so can result in significant delays if you need replacement parts. This note applies if you change the type of line card. It does not apply if you replace these components with the same type of component.
