The line card requires a particular minimum Junos OS release to power on, and that minimum release is
not running on the switch.
Solution
Possible solutions to these problems are:
If the ON LED is unlit:
Ensure that the line card is installed correctly:
Issue the show chassis fpc command. If the state of the line card in the CLI is Empty :
a. Remove the line card (see
b. Reinstall the line card (see
Determine whether the switch has sufficient power to power on the line card while maintaining its
N+1 or N+N power configuration. Use one of the following methods to determine this :
Issue the show chassis fpc command. If the state of the line card in the CLI is Offline and the line
card description is No power, the switch does not have enough power to power on the line card.
Install additional power supplies in the switch. See
Switch" on page 240
Determine the power requirement of the line card. See

item below that is appropriate for your switch's software release:
If your switch is running Junos OS Release 10.2 or later, issue the show chassis
power-budget-statistics command. If the value of the Total Power Available field is less than the
power requirement of the line card, the switch does not have enough power to power on the line
card. Install additional power supplies in the switch. See
EX8200 Switch" on page 240
If your switch is running Junos OS Release 10.1 or earlier, calculate the total power available—see
"Calculating Power Requirements for an EX8208 Switch" on page 121
Requirements for an EX8216 Switch. If the switch does not have enough power to power on the
line card, install additional power supplies in the switch. See

Determine whether the line card requires a particular minimum Junos OS release to power on:
a. If your line card has a yellow label on the faceplate, a tag on the left ejector, and one of the following
model number and part number combinations, it requires a particular Junos OS release to power
on (see Figure 98 on page
