Description
Display Power Entry Module (PEM) environmental status information.
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.
Starting in Junos OS Release 23.1, on QFX10008 and QFX10016 switches, you can see the version of the primary firmware available on the power supply.
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 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 router and TX Matrix Plus router only) (Optional) Line-card chassis number. Replace number with the following values depending on the LCC configuration:
|
| 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. |
| satellite [fpc-slot slot-id | device-alias alias-name] | (Junos Fusion only)(Optional) Display environmental information about the PEM in the specified satellite device in a Junos Fusion, or for all satellite devices in the Junos Fusion if no satellite devices are specified. |
| 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. |

Output Fields
Table 1 lists the output fields for the show chassis environment
pem command. Output fields are listed in the approximate order
in which they appear.
Field Name |
Field Description |
|---|---|
PEMslotstatus |
Number of the PEM slot. |
State |
Status of the PEM. Note: PEM with no feeds connected at bootup on MX10004 and MX10008 devices,
continues to stay in "Present" state until feeds are connected to it. PEM with
feeds connected at bootup, continues to move to OFFLINE state. "Present" state is
only a transitional state that can either move to OFFLINE (or) ONLINE depending on
the PEM output. For example, a PEM with no feeds connected at bootup, moves
through the states from "Empty" to "Present" to "Offline" state.
|
Temperature |
Temperature of the air flowing past the PEM. |
AC Input |
Status of the AC input for the specified component |
AC Output |
Status of the AC output for the specified component. |
DC input |
Status of the DC input for the specified component. |
DC output |
Status of the DC output for the specified component. |
Load |
(Not available on M40e or M160 routers) Information about the load on supply, in percentage of rated current being used. |
Voltage |
(M120, M160, M320, T640, T1600, TX Matrix, and TX Matrix Plus routers only) Information about voltage supplied to the PEM. (MX104 routers only) Information about voltage supplied by the PEM to the system. |
Current |
(T640, T1600, TX Matrix, and TX Matrix Plus routers only) Information about the PEM current. |
Power |
(T640, T1600, TX Matrix, and TX Matrix Plus routers only) Information about the PEM power. |
SCG/CB/SIB |
(T640, T1600, TX Matrix, and TX Matrix Plus routers only) SONET Clock Generator/Control Board/Switch Interface Board. |
FAN |
(T640, T1600, and T4000 routers with six-input DC power supply only) Information about the DC output to the fan. |
