Output Fields

Table 5 lists the output fields for the show chassis environment cb command. Output fields are listed in the approximate order in which they appear.

Table 5: 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.

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.

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.

FPGA Revision

Revision level of the field-programmable gate array (FPGA).

PMBus device

Enhanced SCB on SRX Series devices 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 devices with Enhanced MX SCB:

  • Expected voltage
  • Measured voltage
  • Measured current
  • Calculated power
