The Cisco Nexus 9000 Series NX-OS mode switches contain several programmable logical devices (PLDs) that provide hardware functionalities in all modules. Cisco provides electronic programmable logic device (EPLD) image upgrades to enhance hardware functionality or to resolve known issues. PLDs include electronic programmable logic devices (EPLDs), field programmable gate arrays (FPGAs), and complex programmable logic devices (CPLDs), but they do not include ASICs. In this document, the term EPLD is used for FPGA and CPLDs.
The advantage of having EPLDs for some module functions is that when you need to upgrade those functions, you just upgrade their software images instead of replacing their hardware.
NOTE: EPLD image upgrades for a line card disrupt the traffic going through the module because the module must power down briefly during the upgrade. The system performs EPLD upgrades on one module at a time, so at any one time the upgrade disrupts only the traffic going through one module.
Cisco provides the latest EPLD images with each release. Typically, these images are the same as provided in earlier releases but occasionally some of these images are updated. These EPLD image updates are not mandatory unless otherwise specified. The EPLD image upgrades are independent from the Cisco In Service Software Upgrade (ISSU) process, which upgrades the system image with no impact on the network environment.
When Cisco makes an EPLD image upgrade available, these release notes announce their availability, and you can download the EPLD images from https://software.cisco.com/download/navigator.html.
When new EPLD images are available, the upgrades are always recommended if your network environment allows for a maintenance period in which some level of traffic disruption is acceptable. If such a disruption is not acceptable, then consider postponing the upgrade until a better time.
NOTE: The EPLD upgrade operation is a disruptive operation. Execute this operation only at a programmed maintenance time. The system ISSU upgrade is a nondisruptive upgrade.
NOTE: Do not perform an EPLD upgrade during an ISSU system upgrade.
NOTE: If the NXOS image supports the digital signature feature and the EPLD image is not signed digitally, then the user needs to configure “no feature signature-verification”, for the EPLD process to proceed.

You must have administrator privileges to work with the Cisco Nexus 9000 Series switch.
Each EPLD image that you can download from https://software.cisco.com/download/navigator.html is a bundle of EPLD upgrades. To see the recent updated EPLD versions for the Cisco Nexus 9200, 9300, 9300-EX, and 9300-FX platform switches, and the Cisco Nexus 9500 platform switches, see the following tables.
NOTE: All updates to an image are shown in boldface. If more than one release is shown for a column, the boldface applies to the first release listed for the column.
NOTE: All image numbers represent the latest information for each release. If your release is not shown in the following tables, please use the image numbers for the previous release.
Available EPLD Images for the Cisco Nexus 9200, 9300, 9300-EX, and 9300-FX Platform Switches
1 Not available in this release.
Available EPLD Images for the Cisco Nexus 9500 Platform Switches
2 Not available in this release.
To determine which devices need upgraded EPLDs, use the show install impact epld bootflash: command for a device and indicate the latest EPLD image file (n9000-epld.7.0.3.I7.3.img). The output for this command indicates the current EPLD images, new EPLD images, and whether the upgrades would be disruptive to switch operations. If the currently installed EPLD version number is greater than the new EPLD image number, you can skip the upgrade.
■ To determine the EPLD upgrades needed for a Cisco Nexus 3000 Series switch, use the show install impact epld bootflash: command on that switch and indicate the n9000-epld.7.0.3.I7.3 image. In the following example, the MIFPGA and IOFPGA EPLD images do not need to be upgraded.
show install all impact epld n9000-epld.7.0.3.I7.3.img
Before you can prepare the EPLD images for installation, you must download them to the FTP or management server.
To upgrade the EPLD images using CLI commands, follow these guidelines:
■ Before you upgrade any EPLD images, be sure that you have updated the Cisco NX-OS operating system to the level required for the images and be sure that you have an EPLD image file.
■ You can execute an upgrade from the active supervisor module only. This upgrade is for one or all of the modules as follows:
— You can upgrade a module individually.
— You can upgrade all modules sequentially.
— You can update the images for online modules only.
■ On a Cisco Nexus 9500 platform switch that has two supervisor modules, upgrade the EPLDs for the standby supervisor and then switch the active supervisor to the standby mode to upgrade its EPLDs (the supervisor switchover is not disruptive to traffic on Cisco Nexus 9500 platform switches). On a switch that has only one supervisor module, you can upgrade the active supervisor, but this will disrupt its operations during the upgrade.
■ If you interrupt an upgrade, you must reapply the upgrade to the module that was being upgraded during the interruption.
■ The upgrade process disrupts traffic on the targeted module.
■ Do not insert or remove any modules while an EPLD upgrade is in progress.
Note: The correct order of installation is first the BIOS, and then the EPLD.
Verifying the EPLD Upgrades
To verify the EPLD upgrades for a switch or its modules, use the show version module slot-number epld command as follows:
■ To verify updates for a module on a modular switch (Cisco Nexus 9500 platform switches), indicate the chassis slot number for slot-number.
switch# show version module 22 epld
■ To verify updates for a top-of-rack switch (Cisco Nexus 9200, 9300, and 9300-EX platforms), use 1 for slot-number.
switch# show version module 1 epld
Displaying the Status of EPLD Upgrades
To display the status of EPLD upgrades on the switch, use the show install epld status command.
When EPLDs are upgraded, the following guidelines and observations apply:
■ If a module is not online, you cannot upgrade its EPLD images.
■ If there are two supervisors installed in the switch (Cisco Nexus 9504, 9508, and 9516 switches only), you can either upgrade only the standby supervisor from the active supervisor or upgrade all modules (including both supervisor modules) by using the following commands:
— install epld bootflash: image module standby-supervisor-slot-number (upgrades only the standby supervisor module)
NOTE: After you use this command, you can switchover the active and standby supervisor modules and then upgrade the other supervisor.
— install epld bootflash: image module all (upgrades all of the modules)
■ If there is only one supervisor installed in the switch, your upgrading or downgrading of EPLD images is disruptive.
