consumption. Thus, by configuring an appropriate ambient temperature, you can reduce the provisioned
power and save cost on network power infrastructure.
You can configure ambient temperature by using the set chassis ambient-temperature (25C|40C|55C)
statement at the [edit chassis] hierarchy level. The default ambient temperature for SRX5800 Services
Gateways is 55°C.
Monitoring the Power Consumption of SRX5800 Services Gateways Cards
by Configuring the Ambient Temperature
You can configure the ambient temperature of the SRX5800 chassis to manage power allocated to the
cards. You can set the ambient temperature of the chassis at 25° C, 40° C, or 55° C. On system initialization,
the power manager reads the ambient temperature and allocates power to the cards according to the
power budget policy at that temperature.
1. To configure the ambient temperature, include the set chassis ambient-temperature 25|40|55 statement
at the [edit] hierarchy level in the configuration mode:
[edit]
user@host# set chassis ambient-temperature 25|40|55
2. To verify the ambient temperature of the chassis, use the show chassis ambient-temperature command
at the [edit] hierarchy level in the operational mode:
[edit]
user@host> show chassis ambient-temperature
To verify the power consumption of the cards, use the following statements:
1. Use the show chassis power detail | grep "FPC" statement at the [edit] hierarchy level to view the
power consumption of the FPCs.
user@host> show chassis power detail | grep "FPC"
Alternatively use the SNMP MIB command, show snmp mib walk jnxOperatingFRUPower | grep "\.7\."
to view the power consumption of each FPC:
user@host> show snmp mib walk jnxOperatingFRUPower | grep "\.7\."
2. Use the show chassis alarms statement to view the alarms generated for any of the cards:
