Release Information

Command introduced in Junos OS Release 10.0

Command introduced in Junos OS Release 12.1 for PTX Series Packet Transport Switches.

Description

(MX Series 3D Universal Edge Routers and PTX Series Packet Transport Switches only) Display power limits and usage information for the AC or DC power sources.

  • On the MX Series 3D Universal Edge Routers, power is supplied by Power Entry Modules (PEMs).

    Note: The new high-capacity (4100 W) enhanced DC PEM on MX960 routers includes a new design that can condition the input voltage. This results in the output voltage differing from the input voltage. The earlier generation of DC PEMs coupled the input power directly to the output, thereby making it safe to assume that the output voltage was equal to the input voltage.

  • On the PTX Series Packet Transport Switches, power is supplied by power distribution units (PDUs). Each PDU contains up to four Power Supply Modules (PSMs).

Options

none

Display basic power usage information for the AC and DC power sources.

all-members

(MX Series routers only) (Optional) Display power usage information for all members of the Virtual Chassis configuration.

detail

(PTX Series only) (Optional) Include power usage for specific FRUs.

local

(MX Series routers only) (Optional) Display power usage information for the local Virtual Chassis member.

member member-id

(MX Series routers only) (Optional) Display power usage information for the specified member of the Virtual Chassis configuration. For an MX Series Virtual Chassis, replace member-id with a value of 0 or 1.

Field Name

Field Description

Level of Output

PEM number

(MX Series only) AC or DC PEM number on the chassis. The following output fields are displayed for the PEM:

  • State—State of the PEM:
    • Online—PEM is present in the slot and online.
    • Empty—PEM is not present in the slot.
    • Present—PEM is present in the slot, but not online.
  • AC/DC InputOK or Check—State of the AC or DC input power feed with the number of active and expected feeds (one or two).

    For a DC input power feed, this output field also displays the reference voltage input with maximum input voltage displayed in mV (in parentheses) for the AC or DC PEM.

  • Capacity—Actual power input capacity with maximum capacity displayed (in parentheses) in watts.

    Note: The maximum capacity for AC and DC PEMs is:

    • MX960 AC PEM—4100 W if two feeds are connected. 1700 W if one feed is connected.
    • MX960 DC PEM—4100 W if two feeds are connected. 1700 W if one feed is connected.
    • MX480 AC PEM—2520 W if it is high-line. 1450 W if it is low-line.
    • MX480 DC PEM—2400 W if the DIP switch is off. 2600 W if the DIP switch is on.
    • MX240 AC PEM—2520 W if it is high-line. 1450 W if it is low-line.
    • MX240 DC PEM—2400 W if the DIP switch is off. 2600 W if the DIP switch is on.
  • DC Output—DC power output in Watts for the specified zone, at the specified amps and voltage (A @ V), and load and percentage utilization of the maximum capacity) for the zone.

All levels

System

(MX Series only) Overall power statistics for the system zone:

  • Zone number:
    • Capacity—Maximum power capacity applicable for the zone, in watts.
    • Allocated power—Actual capacity allocated for the zone, in watts, with remaining power displayed in parentheses.
    • Actual usage—Actual power usage for the zone, in watts.
  • Total system capacity—Cumulative power capacity of all the zones, in watts.
  • Total remaining capacity—Difference between the Total system capacity and cumulative Allocated power of all the zones, in watts.

All levels

Total Power

(PTX Series only) Total power used by the switch (displayed in watts).

All levels

PDU number

(PTX Series only) ID number of the power distribution unit (PDU) on the chassis..

All levels

PSM number

(PTX Series only) ID number of the Power Supply Unit contained in the PDU.

The following output fields are displayed for each PSM:

  • Input (V)—Voltage supplied to the PSM.
  • Used (W)—Actual power usage for the PSM (measured in watts).

All levels

Item

(PTX Series only) (detail keyword only) Actual power usage (measured in watts) for individual FRUs.

PTX Switches include the following FRUs:

  • Fan Tray n—Power usage for the specified fan tray.
  • REn/CBn—Power usage for the specified Routing Engines and Control Boards
  • SIB/CCG/FPD—Power usage for the Switch Interface Board, Centralized Clock Generator, and Front Panel Display (craft interface).
  • FPC n—Power usage for the FPC in the slot specified.
