Chapter 6 Managing the Device Hardware

EPLD Configuration

The possible Status field values for a fan module on the Cisco Nexus 7000 Series devices are as follows:

• 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 proper l y, the status is f ail ur e.

On the Cisco Nexus 7010, each system fan module has 15 fans. If t he 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 Exampl e 6-9).

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.
