Syntax
Syntax (TX Matrix and TX Matrix Plus Router)
Release Information
Command introduced before Junos OS Release 7.4.
Command introduced in Junos OS Release 12.1 for the T4000 Core Routers.
Description
Display SONET Clock Generator (SCG) environmental information.
Options
none | — | (TX Matrix and TX Matrix Plus routers only) Display environmental information about all SCGs. On a TX Matrix router, display environmental information about all SCGs on the TX Matrix router and its attached T640 routers. On a TX Matrix Plus router, display environmental information about all SCGs on the TX Matrix Plus router and its attached T1600 routers. |
lcc number | — | (TX Matrix and TX Matrix Plus routers only) (Optional) On a TX Matrix router, display environmental information about the SCG in a specified T640 router (or line-card chassis) that is connected to the TX Matrix router. On a TX Matrix Plus router, display environmental information about the SCG in a specified T1600 router (or line-card chassis) that is connected to the TX Matrix Plus router. Replace number with a value from 0 through 3. |
slot | — | (Optional) Display environmental information about the SCG. Replace slot with 0 or 1. |

Output Fields
Table 1 lists the output fields for the show chassis environment scg command. Output fields are listed in the approximate order in which they appear.
Table 1: show chassis environment scg Output Fields
Field Name | Field Description |
|---|---|
SCG slot status | Number of the SCG slot: 0 or 1. |
State | Status of the SCG:
If two SCGs are installed and online, one is functioning as the master, and the other is the standby. |
Temperature | Temperature of the air flowing past the SCG. |
Power | Power on the SCG. The left column displays required power, in volts. The right column displays measured power, in millivolts. |
BUS Revision | Revision level of the generic bus device. |
