Configuring the Power Priority of Line Cards (CLI Procedure)

The power management facility on EX8200 switches allows you to assign power priorities to the slots occupied by line cards. Power management provides power to the slots in priority order, which means that line cards in higher priority slots are more likely to receive power than line cards in lower priority slots if power to the switch is insufficient to power all the line cards.

When assigning power priority to slots, keep these points in mind:

  • 0 is the highest priority. For an EX8208 switch, you can assign a priority of 0 through 7 to a slot. For an EX8216 switch, you can assign a priority of 0 through 15 to a slot.
  • All slots are assigned the lowest priority by default.
  • If a group of slots shares the same assigned priority, each slot’s power priority within the group is based on its slot number, with the lowest-numbered slots receiving power first.

To assign or change the power priority for a slot:

[edit chassis]user@switch# set fpc slot power-budget-priority priority

For example, to set slot 6 to priority 0, enter:

[edit chassis]
user@switch# set fpc 6 power-budget-priority 0
