Description

(M120, M320, MX Series, and T Series routers, EX8200 switches, and PTX Series Packet Transport Routers only) Display environmental information about the Control Boards (CBs).

Options

noneDisplay environmental information about all CBs. For a TX Matrix router, display environmental information about all CBs on the TX Matrix router and its attached T640 routers. For a TX Matrix Plus router, display environmental information about all CBs on the TX Matrix Plus router and its attached T1600 or T4000 routers.
all-members(MX Series routers only) (Optional) Display environmental information about the CBs on all the members of the Virtual Chassis configuration.
interconnect-device(QFabric systems only) Display environmental information about CBs on 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:

  • 0 through 3, when T640 routers are connected to a TX Matrix router in a routing matrix.

  • 0 through 3, when T1600 routers are connected to a TX Matrix Plus router in a routing matrix.

  • 0 through 7, when T1600 routers are connected to a TX Matrix Plus router with 3D SIBs in a routing matrix.

  • 0, 2, 4, or 6, when T4000 routers are connected to a TX Matrix Plus router with 3D SIBs in a routing matrix.

local(MX Series routers only) (Optional) Display environmental information about the CBs on the local Virtual Chassis member.
member member-id(MX Series routers only) (Optional) Display environmental information about the CBs on the specified member of the Virtual Chassis configuration. Replace member-id with a value of 0 or 1.
scc(TX Matrix router only) (Optional) Display environmental information about the CBs in the TX Matrix router (switch-card chassis).
sfc number(TX Matrix Plus router only) (Optional) Display environmental information about the CBs in the TX Matrix Plus router (or switch-fabric chassis).
slot(Optional) Display environmental information about the specified CB. On routers and PTX Series Packet Transport Routers, replace slot with 0 or 1. On EX Series switches replace slot with 0, 1, or 2. On QFX Series switches, replace slot with 0 or 1.

Output Fields

Table 1 lists the output fields for the show chassis environment cb command. Output fields are listed in the approximate order in which they appear.

Table 1: show chassis environment cb Output Fields

Field Name

Field Description

State

Status of the CB. If two CBs are installed and online, one is functioning as the master, and the other is the standby.

  • Online—CB is online and running.

  • Offline— CB is powered down.

Note: On the EX8208 switch, the installation can include three CBs.

Temperature

Temperature in Celsius (C) and Fahrenheit (F) of the air flowing past the CB.

  • Temperature Intake—Measures the temperature of the air intake to cool the power supplies.

  • Temperature Exhaust—Measures the temperature of the hot air exhaust.

Note: On the MX2010, MX2020, and MX2008 routers, the intake temperature measures the temperature of the air intake to cool the Control Board (CB). The MX2010, MX2020, and MX2008 routers include intake and exhaust temperatures for multiple zones (Intake A, Intake B, Intake C, Exhaust A, Exhaust B, and TCBC).

Power

Power required and measured on the CB. The left column displays the required power, in volts. The right column displays the measured power, in millivolts.

BUS Revision

Revision level of the generic bus device. (Not on switches.)

FPGA Revision

Revision level of the field-programmable gate array (FPGA). (Not on switches.)

PMBus device (on MX240, MX480, and MX960 routers with Enhanced MX SCB)

Enhanced SCB on MX 240, MX480, and MX960 routers allows the system to save power by supplying only the amount of voltage that is required. Configurable PMBus devices are used to provide the voltage for each individual device. There is one PMBus device for each XF ASIC so that the output can be customized to each device. The following PMBus device information is displayed for routers with Enhanced MX SCB:

  • Expected voltage

  • Measured voltage

  • Measured current

  • Calculated power

Starting in Junos OS Evolved Release 19.1R1, on PTX10003-80C and PTX10003-160C devices, the show chassis environment cb command does not show the Bus and FPGA revision information. If you want to view the FPGA revision or version information for the CB, use the show system firmware command.
