Measures reported by UCSFIConnsFanModuleTest
A Cisco UCS fabric interconnect is a top-of-rack fabric interconnect that provides Ethernet and Fibre Channel to all servers in the UCS system. Servers connect to the fabric interconnect, and it connects to the LAN or SAN. Depending on the model of the Cisco UCS, the fabric interconnects may contain upto four fan modules. Each fan module contains four fans. The fans in the fan module help ensure adequate air flow to the internals of the fabric interconnect. If the fans in the fan modules are inoperable, then, the temperature of the fabric interconnect may increase which would eventually lead to the malfunctioning of the fabric interconnects. Therefore, it is necessary to constantly monitor the overall status, operational state and the temperature of each fan module housed in the fabric interconnects at regular intervals. The UCSFIConnsFanModuleTest test helps administrators in this regard!
This test auto-discovers the fan modules of the fabric interconnects and for each fan module, this test reports the overall status, power state, operational state and the temperature of the fans. Using this test, administrators can figure out the faulty fan module and replace it before abnormalities are detected in the functioning of the fan modules.
Outputs of the test : One set of results for each fan module in each fabric interconnect managed by the Cisco UCS Manager being monitored.
The measures made by this test are as follows:
