Description

Display chassis temperature threshold settings, in degrees Celsius.

Options

none

Display the temperature threshold details.

all-members

(MX Series routers only) (Optional) Display the chassis temperature threshold settings of all member routers in the Virtual Chassis configuration.

interconnect-device name

(QFabric systems only) (Optional) Display the chassis temperature threshold settings of the Interconnect device.

lcc number

(TX Matrix and TX Matrix Plus routers only) (Optional) On a TX Matrix router, display the temperature threshold details of a specified T640 router (line-card chassis) that is connected to a TX Matrix router. On a TX Matrix Plus router, display the temperature threshold details of a specified router (line-card chassis) that is connected to a TX Matrix Plus router.

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 the chassis temperature threshold settings of the local Virtual Chassis member.

member member-id

(MX Series routers only) (Optional) Display the chassis temperature threshold settings of 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 the chassis temperature threshold settings of the Node device.

satellite [slot-id slot-ID | device-alias alias-name]

(Junos Fusion only) (Optional) Display the chassis temperature threshold settings for the specified satellite device or devices in a Junos Fusion, or for all satellite devices if no satellite devices are specified.

scc

(TX Matrix routers only) (Optional) Display the temperature threshold details of the TX Matrix router (switch-card chassis).

sfc number

(TX Matrix Plus routers only) (Optional) On TX Matrix Plus routers, display the temperature threshold details of the TX Matrix Plus router, which is the switch-fabric chassis. Replace number with 0.

Output Fields

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

Table 1: show chassis temperature-thresholds Output Fields

Field name

Field Description

Item

Chassis component. If per FRU per slot thresholds are configured, the components about which information is displayed include the chassis, the Routing Engines, CPUs, FPCs, and FEBs. If per FRU per slot thresholds are not configured, the components about which information is displayed include the chassis and the Routing Engines.

Fan speed

Note:

On the QFX3500 switch and QFX3600 switch, there are four fan speeds: low, medium-low, medium-high, and high. The fan speed changes at the threshold when going from a low speed to a higher speed. When the fan speed changes from a higher speed to a lower speed, the temperature changes two degrees below the threshold.

Temperature threshold settings, in degrees Celsius, for the fans to operate at normal and high speeds.

  • Normal—The fans operate at normal speed if the component is at or below this temperature and all the fans are present and functioning normally.

    Note:

    On a TX Matrix Plus router with 3D SIBs, the threshold temperature at the XF junction is set to 70°C for Normal fan speed, which is less than or equal to 4800 RPM.

  • High—The fans operate at high speed if the component has exceeded this temperature or a fan has failed or is missing.

    Note:

    On a TX Matrix Plus router with 3D SIBs, the threshold temperature at the XF junction is set to 75°C for High fan speed, which is greater than or equal to 5000 RPM.

Note:

For MX480 Routers, there are three fan speeds: Low, Medium, and High.

An alarm is not triggered until the temperature exceeds the threshold settings for a yellow alarm or a red alarm.

Yellow alarm

Temperature threshold settings, in degrees Celsius, that trigger a yellow alarm.

  • Normal—The temperature that must be exceeded on the component to trigger a yellow alarm when the fans are running at full speed.

  • Bad fan—The temperature that must be exceeded on the component to trigger a yellow alarm when one or more fans have failed or are missing.

Red alarm

Temperature threshold settings, in degrees Celsius, that trigger a red alarm.

  • Normal—The temperature that must be exceeded on the component to trigger a red alarm when the fans are running at full speed.

  • Bad fan—The temperature that must be exceeded on the component to trigger a red alarm when one or more fans have failed or are missing.

Fire Shutdown

(T4000 routers, TX Matrix Plus router with 3D SIBs, and PTX Series Packet Transport Routers only)—Temperature threshold settings, in degrees Celsius, for the network device to shut down.
