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. |
