Log in

Use this procedure to verify NCS 1001 fan, temperature, power, voltage, and current environmental values from the System Admin EXEC mode.

Confirm that environmental parameters are within expected values.

The show environment command displays environmental parameters for NCS 1001.

Follow these steps to verify environmental parameters:

Procedure

1.

Use the admin command to enter System Admin EXEC mode.

Example:

RP/0/RP0/CPU0:ios# admin
2.

Enter the show environment [ all | fan | power | voltages | current | temperatures ] [ location | location ] commands to displays the environmental parameters of the NCS 1001.

Example:

This example shows sample output from the show environment command with the fan keyword.

The output displays the requested environmental values and thresholds for the selected component or location.

What to do next

Environmental parameter anomalies are logged in syslog. If a displayed environmental parameter is not as expected, use the show logging command to review problem details.
