• Ensure that you know how to handle and store the line card (see “Handling and Storing
Line Cards in EX8200 Switches” on page 227).
• 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” on page 111 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” on page 114 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 58 on page 161). The ESD point is at the same
location on EX8208 and EX8216 switches.

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
