Release Information
Command introduced before Junos OS Release 7.4.
Command introduced in Junos OS 11.3 for the QFX Series.
Description
Display Power Entry Module (PEM) environmental status information.
 | Note: The new high-capacity (4100W) 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. |
Options
none | — | Display environmental information about both PEMs. For the TX Matrix router, display environmental information about the PEMs, the TX Matrix router, and its attached T640 routers. For the TX Matrix Plus router, display environmental information about the PEMs, the TX Matrix Plus router, and its attached T1600 routers. |
all-members | — | (MX Series routers only) (Optional) Display environmental information about the PEMs in all the member routers of the Virtual Chassis configuration. |
interconnect-device name | — | (QFabric systems only) (Optional) Display chassis environmental information about the PEMs in the Interconnect device. |
lcc number | — | (TX Matrix and TX Matrix Plus routers only) (Optional) On a TX Matrix router, display environmental information about the PEM in a specified T640 router (or line-card chassis) that is connected to a TX Matrix router. On a TX Matrix Plus router, display environmental information about the PEM in a specified T1600 router (or line-card chassis) that is connected to a TX Matrix Plus router. Replace number with a value from 0 through 3. |
local | — | (MX Series routers only) (Optional) Display environmental information about the PEM in the local Virtual Chassis member. |
member member-id | — | (MX Series routers only) (Optional) Display environmental information about the PEM in the specified member of the Virtual Chassis configuration. Replace member-id with a value of 0 or 1. |
node-device name | — | (QFabric systems only) (Optional) Display chassis environmental information about the PEMs in the Node device. |
scc | — | (TX Matrix routers only) (Optional) Display environmental information about the PEM in the TX Matrix router (or switch-card chassis). |
sfc | — | (TX Matrix Plus routers only) (Optional) Display environmental information about the PEM in the TX Matrix Plus router (or switch-fabric chassis). |
slot | — | (Optional) Display environmental information about an individual PEM. Replace slot with 0 or 1. |
