Measures reported by CisNexusPwrSplyTest

The Cisco Nexus Switch supports dual power supply units that are fully hot swappable and ensuring high-availability requirements. The switch is fully functional with one power supply, but a second power supply can be included for power redundancy. Proper functioning of these power supply units is critical to the uninterrupted operations of the switch. The failure of the power supply units, if not attended promptly, can cause short to prolonged breaks in the availability of the switch. Therefore, administrators should be able to proactively detect potential problems with the power supply units and take remedial action before any unpleasant eventuality happens. This where the CisNexusPwrSplyTest test helps administrators!

This test auto-discovers the power supply units of the Cisco Nexus Switch and reports the current status of each power supply unit. In addition, this test reports the current power to each power supply unit. Using this test, administrators can detect abnormalities, if any, in the current passing through the power supply unit and detect failures at the earliest.

Outputs of the test : One set of results for each power supply unit of the target Cisco Nexus Switch being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
status Indicates the current status of this power supply unit.   The values reported by this measure and its numeric equivalents are mentioned in the table below:

Measure Value Numeric Value
Failed 0
Off due to other environment 1
On 2
Administratively off 3
Off due to insufficiant power 4
Off due to power problem 5
Off due to temperature problem 6
Off due to fan problem 7
On but fan failure 9
Off cooling 10
Off connector rating 11
On but inline power failure 12

Note:

By default, this measure reports the Measure Values listed in the table above to indicate the current state of this power supply unit. The graph of this measure however, represents the status of a server using the numeric equivalents only.
pwrAmps Indicates the current passing through this power supply unit. Amps The value of this measure should be in permissible range. If the value of this measure is found to be higher/lower than the admissible range, administrator should immediately take corrective action before it causes permanent damage to the power supply unit.
