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.
Field Name |
Field Description |
|---|---|
State |
Status of the CB. If two CBs are installed and online, one is functioning as the primary, and the other is the standby.
|
Temperature |
Temperature in Celsius (C) and Fahrenheit (F) of the air flowing past the CB.
|
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 Firewalls 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:
