Obtaining Documentation and Submitting a Service Request
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.
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.
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.
The Cisco Nexus 9000 Series switch must be running the Cisco NX-OS operating system and include the following hardware:
■ Supervisor modules (2)—each with at least 800 MB of available bootflash memory (Cisco Nexus 9504, 9508, and 9516 switches)

■ Uplink module (Cisco Nexus 93128TX, 9396PX, and 9396TX switches only)
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 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.

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 upgrade a module individually.
— You can upgrade all modules sequentially.
— You can update the images for online modules only.
■ The upgrade process disrupts traffic on the targeted module.
■ Do not insert or remove any modules while an EPLD upgrade is in progress.
Enter the install epld bootflash:n9000-epld.7.0.3.I7.5.img module all command. The switch automatically reboots. |
Note: The correct order of installation is first the BIOS, and then the EPLD.
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
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)
— 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.
