Introduction

The Cisco Nexus 7000 Series switches contain several programmable logical devices (PLDs) that provide hardware functionalities in all modules. Cisco provides electronic programmable logical device (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), but they do not include ASICs. In this document, the term EPLD is used for FPGA and CPLDs.

The great 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 an I/O module 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 Systems does not provide upgrade EPLD images very frequently, and you do not have to upgrade your EPLD images unless they fix the functions for the hardware that you are using in your Cisco Nexus 7000 Series switch. The EPLD image upgrades are independent from the Cisco NX-OS In Service Software Upgrade (ISSU) process, which upgrades the system and kickstart images 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 them from http://www.cisco.com.

Deciding When to Upgrade EPLDs

It is not always necessary to upgrade EPLD images; however, 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 at this time, then it is best to postpone the upgrade until a better time.

Table 2 provides high-level guidelines to help network administrators determine whether an EPLD upgrade is necessary. The CDETS listed in this table can be found in the following earlier versions of FPGA/EPLD release notes:

Note To list the EPLDs running on your switch, use the show version module_number epld command. If any of the versions that you list are older than the newest version listed in Table 3, it is recommended that you update the EPLDs.


Determining Whether to Upgrade EPLD Images

You can upgrade EPLD images for all online modules on your switch (except for the active supervisor module) or for individual online modules.

This section includes the following topics:

Determining Whether to Upgrade EPLDs for All Modules

Determining Whether to Upgrade EPLDs for an I/O or Supervisor Module

Determining Whether to Upgrade EPLDs for a Fabric Module

Determining Whether to Upgrade EPLDs for a Fan Tray Module

Determining Whether to Upgrade EPLDs for All Modules

To determine whether you need to update the EPLDs for any of the online modules on your switch, use the show install all impact epld url command as shown in Example 1. This command displays a report that indicates whether the upgrade is disruptive for the module, whether each module can be upgraded, and whether an upgrade is available for each EPLD on each module.

EPLD Images Needed for vPCs

The virtual port channel (vPC) feature is available beginning with Cisco NX-OS Release 4.1(3). When you enable vPC on the chassis, you must have EPLD Release 186.3 on the 32-port 10 Gbps Ethernet IO modules (N7K-M132XP-12).


Note The EPLD upgrade operation is a disruptive operation. You should execute this operation only at a programmed maintenance time. The system/kickstart ISSU upgrade is a nondisruptive upgrade.


Most of the N7K-M132XP-12 modules in the chassis already meet this minimum EPLD requirement, but if you are working with a N7K-M132XP-12 module that was shipped before June 2008, you might need to upgrade the EPLD version.

To determine the EPLD version for all N7K-M132XP-12 modules, enter the show version module module_id epld. If the line FE Bridge(x) version displays a version earlier than 186.3 (for example, 186.2), you should schedule an EPLD upgrade to a version that is compatible with the target NX-OS release. For example, if you want to run Cisco NX-OS Release 4.1(3), you should choose Release 4.1(3) EPLDs.

The following example shows Release 186.3 on the FE Bridge line, which is the correct EPLD version:

switch(config)# show ver mod 7 epld

Installation Guidelines

You can upgrade (or downgrade) EPLDs using CLI commands on the Cisco Nexus 7000 Series switch. Follow these guidelines when you upgrade or downgrade EPLDs:

Before you upgrade any EPLD images, be sure that you have updated the Cisco NX-OS operating system to the level required for the image and you have downloaded the EPLD images for the current version of the Cisco NX-OS operating system.

You can execute an upgrade from the active supervisor module only. All the modules, including the active supervisor module, can be updated individually.

You can individually update each module whether it is online or offline as follows:

If you upgrade EPLD images on an online module, only the EPLD images with version numbers that differ from the new EPLD images are upgraded.

If you upgrade EPLD images on an offline module, all of the EPLD images are upgraded.

On a switch that has two supervisor modules, upgrade the EPLDs for the standby supervisor and then switch the active supervisor to standby mode to upgrade its EPLDs (the supervisor switchover is not disruptive to traffic on Cisco Nexus 7000 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 upgrade the module that is being upgraded again.

The upgrade process disrupts traffic on the targeted module.

Do not insert or remove any modules while an EPLD upgrade is in progress.

Downloading the EPLD Images

Before you can prepare the EPLD images for installation, you must download them to the FTP or management server.

To download the EPLD images, follow these steps:

You are ready to prepare the EPLD images for Installation (see the "Preparing the EPLD Images for Installation" section).


Preparing the EPLD Images for Installation

Before you can update the EPLD images for each of your switch modules, you must determine the Cisco NX-OS version that your switch is using, make sure there is space for the new EPLD images, and download the images.

To prepare the EPLD images for installation, follow these steps:


Step 1 Log into the switch through the console port, an SSH session, or a Telnet session.

Step 2 Verify that the switch is using the expected version of the Cisco NX-OS operating system. The kickstart and system lines indicate the Cisco NX-OS version. This step determines the versions of EPLD images that you must download.

Step 3 Verify that you have 120 MB of free space on the active or standby supervisor memory devices for the EPLD images that you will be downloading by using the dir bootflash: or dir slot0: commands. By default, these commands display the used and free memory for the active supervisor. If your switch has an additional supervisor (a standby supervisor), use the show module command to find the module number for the other supervisor, use the attach module command to attach to the module number, and then use the dir bootflash: or dir slot0: command to determine the amount of used and free memory. See Example 5 to determine the amount of available bootflash memory, and see Example 6 to determine the amount of available slot0 memory.

Step 4 If there is not at least 120 MB of memory free for the EPLD files, delete some unneeded files, such as earlier images, so there is enough free memory.

switch# delete bootflash:n7000-s1-kickstart.4.2.6.bin

Step 5 Copy the EPLD image file from the FTP or management server to the bootflash or slot0 memory in the active supervisor module. The following example shows how to copy from the FTP server to the bootflash memory.

switch# copy ftp://10.1.7.2/n7000-s1-epld.4.2.6.img bootflash:n7000-s1-epld.4.2.6.img

Step 6 Copy the EPLD image to the standby supervisor.

switch# copy bootflash:n7000-s1-epld.4.2.6.img 
bootflash://sup-standby/n7000-s1-epld.4.2.6.img


You are ready to upgrade the EPLD images (see the "Upgrading EPLD Images" section).

Upgrading EPLD Images

You can update the EPLD images for all of the installed modules or a specific installed module. When you request an upgrade, the Cisco NX-OS software tries to list the current and new versions for each EPLD with the following results:

If a module is installed and online, the software lists the installed and new versions for each EPLD. Where there is a difference in versions, the software indicates an upgrade or downgrade to occur when you confirm the upgrade.

If a module is installed and offline, the software cannot list its current EPLD versions so all EPLDs will be updated when you confirm the upgrade.

If a module is not installed, the software displays an error message and does not upgrade the EPLDs.

The following sections explain how to upgrade the EPLD images for I/O and standby modules, the active supervisor module on switches with single-supervisor modules, fabric modules, and fan tray modules.

Upgrading the EPLD Images for All Installed Modules

Upgrading the EPLD Images for an I/O or Standby Supervisor Module

Upgrading EPLDs for the Active Supervisor Module

Upgrading EPLDs for a Fabric Module

Upgrading EPLDs for a Fan Tray Module

Upgrading the EPLD Images for All Installed Modules

You can upgrade the EPLD images for all installed modules while the switch is operational. This type of upgrade includes updates of EPLD images for the standby supervisor module, all I/O modules, all fabric modules, and all fan modules, but this upgrade does not update the EPLDs for the active supervisor module. To upgrade the EPLDs for the active supervisor module, see the "Upgrading EPLDs for the Active Supervisor Module" section.

To upgrade EPLDs for all installed modules (except the active supervisor module), follow these steps:


Step 1 Enter the install all epld url command.

switch# install all epld bootflash:n7000-s1-epld.4.2.6.img

The above modules require upgrade.
Do you want to continue (y/n) ? [n] y

Step 2 If one or more of the EPLDs should be upgraded, enter y to begin the upgrade. Otherwise, enter n for no upgrade.


Upgrading the EPLD Images for an I/O or Standby Supervisor Module

You can upgrade the EPLD images for an I/O module or standby supervisor module while the switch is operational. If you need to upgrade EPLD images for a single supervisor module, see the "Upgrading EPLDs for the Active Supervisor Module" section.


Caution Upgrading EPLD images for an online I/O module can disrupt traffic going through that module.

To upgrade EPLDs for an I/O module or the standby supervisor module, follow these steps:


Step 1 Determine the slot number for the module that you are upgrading EPLDs by entering the show module command.

Step 3 If one or more EPLDs require an upgrade, enter Y for yes.

Do you want to continue (y/n) ? Y

Step 4 For Release 4.0(2) or earlier releases, if you updated the power management EPLD image, you must reset the power for the module so that EPLD can take effect (this is not required for Release 4.0(3) or later releases). You can reset the power in one of the following two ways:

To reset the power for a module, physically remove the module and reinstall it.


Note A module reload or just pressing the ejector buttons on the module is not sufficient for this reset requirement.


To reset an entire switch, power cycle the switch.

To confirm the EPLD upgrade, see the "Displaying EPLD Versions for an I/O or Supervisor Module" section.


Caution Resetting the power disrupts any data traffic going through the affected modules. If you power cycle the entire switch, all data traffic going through the switch at the time of the power cycling is disrupted. This is not necessary for Release 4.0(3) or later releases.


Note As of Release 4.0(3) or later releases, the switch automatically loads the new power management EPLD after an upgrade, so it is no longer necessary to reset the power for the module or switch.



Upgrading EPLDs for the Active Supervisor Module

When you upgrade EPLDs on a switch with only one supervisor module, data traffic on the switch will be affected when you reload the device after the upgrade. If you are upgrading EPLDs for a switch with two supervisor modules, you can upgrade the standby supervisor while the switch is operational as described in the "Upgrading the EPLD Images for an I/O or Standby Supervisor Module" section, and then switch the active supervisor into standby mode and update that module.

To upgrade EPLDs for the active supervisor module, follow these steps:


Step 1 Enter the show module command to determine the slot number for the active supervisor module. On a Cisco Nexus 7010, the active supervisor module is in either slot 5 or slot 6. On a Cisco Nexus 7018, the active supervisor module is in either slot 9 or slot 10.

Limitations

When EPLDs are upgraded or downgraded, the following guidelines and observations apply:

You cannot upgrade the Local Bus CPLD and CMP CPLD while you are upgrading a supervisor module in the 4.0(1) release only.

You must upgrade each installed module individually. If the module is online, Cisco NX-OS upgrades only the EPLD images that have different current and new versions. If the module is offline, all EPLDs are upgraded, even if their version numbers are the same.

If you interrupt an upgrade, you must upgrade the module again.

You can execute an upgrade or downgrade only from the active supervisor module. On switches with two supervisors, upgrade the standby supervisor and then switch the standby supervisor to active to place the previously active supervisor module in standby mode. Upgrade the EPLDs on the standby supervisor. On switches that have only one supervisor, you must upgrade or downgrade the EPLDs on the active supervisor, which will interfere with data traffic during the upgrade.

Release 4.1(2) does not provide EPLD upgrades for the Cisco Nexus 7018 fan controller.
