Output Fields

Table 1 lists the output fields for the show chassis power-budget-statistics command. Output fields are listed in the approximate order in which they appear.

Table 1: show chassis power-budget-statistics Output Fields

Field Name

Field Description

PSU n (supply type)

Capacity rating of the power supply and whether the power supply is currently operating (Online) or not (Offline). If a power supply is offline, the capacity is shown as 0 W.

Total Power supplied by all Online PSUs

Total number of watts supplied by all currently operating power supplies.

Power Redundancy Configuration

Configured power redundancy setting, either N+1 or N+N.

Base power reserved

Total number of watts reserved for the switch.

Non-PoE power being consumed

The amount of power, in W, currently being consumed for PoE.

Power Reserved for the Chassis

Power reserved for the chassis:

  • For an EX6200 switch, 500 W.

  • For an EX8208 switch: 1600 W in an N+1 configuration; 1200 W in an N+N configuration

  • For an EX8216 switch: 2400 W in an N+1 configuration; 1800 W in an N+N configuration

The power reserved for the chassis includes the maximum power requirements for the fan tray and Switch Fabric and Routing Engine (SRE), Routing Engine (RE), and Switch Fabric (SF) modules in both base and redundant configurations.

Fan Tray Statistics

(EX6200 switch only) Information about the fan tray:

  • Base power—Power allocated to the fan tray in the power budget. This allocation is included in Power Reserved for the Chassis.

  • Power Used—Actual power being used by the fan tray. This value is for informational purposes only: the power budget for the switch is based on allocated power (the theoretical maximum the fan tray might use) rather than used power.

FPC n (card type

Information about the line card installed in slot n. For EX6200 switches, information about the SRE modules in slot 4 and slot 5 is also shown.

  • Base power—For line cards without PoE ports, the total power allocated to the line card.

    For line cards with PoE ports, the power allocated to the line card before the PoE power budget is allocated. The base power includes 37 W of PoE power that is always allocated to line cards that support PoE.

  • Power Used—(EX6200 switch only) The actual power being consumed by the line card or SRE module, including PoE power. This value is for informational purposes only: the power budget for the switch is based on allocated power (the theoretical maximum the line card might use) rather than used power.

  • PoE power—For line cards with PoE ports, the PoE power budget allocated to the line card. This value includes the 37 W of PoE power that is always part of the base power allocation for line cards that support PoE.

    For line cards without PoE ports, the value is always 0 W.

  • The power priority assigned to the line card slot.

Total (non-PoE) Power allocated

Power budgeted for all the components in the switch, excluding the PoE power budget allocated to line cards. This value is equal to the power reserved for the chassis plus the base power allocations of all online line cards.

Total Power allocated for PoE

The total of the PoE power budgets allocated to the line cards in the switch. This figure includes the 37 W of PoE power always included in the base allocation for each line card that supports PoE.

Total PoE power consumed

The amount of power that has been consumed by PoE.

Total PoE power remaining

The amount of available power remaining that can be used for PoE.

Power Available (Redundant case)

Unused power available to the switch in the power budget, not including the power reserved for redundancy. If power is insufficient to meet the N+1 or N+N redundancy requirements, this value is 0. PoE power allocations are not included in the calculation of this value.

Total Power Available

Unused power available to the switch in the power budget. This value is derived by subtracting all power allocations, including PoE power allocations, from the total power available on the switch (the Total Power supplied by all Online PSUs value).
