Troubleshooting Line Card Installation on EX8200 Switches on page 237
The ON LED on a line card does not blink in green or is not lit steadily after the line card
is installed in an EX8200 switch.
One or both of these has caused these problems:
The switch does not have sufficient power to power the line card while maintaining its
N+1 or N+N power configuration.
The line card is not seated correctly in the slot in the switch chassis.
If the LED does not blink in green:
1. ON
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 105 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
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 108
or Calculating Power Requirements for an EX8216 Switch to calculate the available
power.
If the LED does not blink still, remove the line card (see "Removing a Line Card
ON
from an EX8200 Switch" on page 216) and reinstall the line card (see "Installing a
Line Card in an EX8200 Switch" on page 154).
If the LED blinks in green, but is not lit steadily, tighten the captive screws on the
2. ON
faceplate of the line card.
