The possible Status field values for a fan module on the Cisco Nexus 7000 Series devices are as follows:
•
•
•
On the Cisco Nexus 7010, each system fan module has 15 fans. If the State field for one of these fans
contains "failure" in the show environment fan command output, it also displays the number of the
failing fans (see

EPLD Configuration

The Cisco Nexus 7000 Series devices contain several programmable logical devices (PLDs) that provide
hardware functionalities in all modules. Cisco provides EPLD image upgrades to enhance hardware
functionality or to resolve known issues. PLDs include electronic programmable logical devices
(EPLDs), field programmable gate arrays (FPGAs), and complex programmable logic devices (CPLDs).
In this document, the term EPLD is used for FPGA and CPLDs.

System Requirements

This section includes the following topics:
OL-18634-01
If the fan module is operating properly, the status is ok.
If the fan is physically absent, the status is absent.
If the fan is physically present but not working properly, the status is failure.
