Configuring the Cajun P550 Switch (Layer 2 & Layer 3)
3-40 Cajun P550/P220 Switch Operation Guide
Note: The supervisor modules shut down the switching modules if the temperature
reaches the Shutdown temperature. The modules are restarted if the
temperature goes below the Upper Warning Temperature. The default
Shutdown temperatures are conservative for the slot 1 sensor (50° C) and
backplane sensor (50° C). They can be safely set to 60° C, but settings higher
than 60° C are not recommended. You can set the shutdown temperature to a
value lower than 50° C to ensure prompt notification if a fan fails.
Displaying the Power System Statistics
To display the power system statistics:
1. In the System Information section of the Web Agent window, click Power
System. The Power System dialog box opens.
2. Use Table 3-21 to review your power system statistics:
Note: The power system settings will only display 600W of available power with
three power supplies installed. This is because the switch uses a maximum of
two power supplies. The third power supply is held in reserve for redundancy
in the event one of the other power supplies fails.
Displaying Cooling System Statistics
To display the switch’s cooling system status:
1. In the System Information section of the Web Agent window, click Cooling
System. The Cooling System dialog box opens.
2. Ensure that all the individual components are operational by checking the status
column for each component.
3. If a component’s status is non-operational, power down the switch and contact a
service representative to diagnose the failing unit.
