Introduction

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:

•Supported Device Hardware

•Supported Device Operating Systems

Supported Device Hardware

The Cisco Nexus 7000 Series device must include the following hardware:

•One or two supervisor modules, each with at least 120 MB of available bootflash or slot0 memory

•One or more I/O modules

•One or more fabric modules

•Two fabric fan tray modules

•Two system fan tray modules

You must be able to access the system through a console, SSH, or Telnet.

You must have administrator privileges to work with the Nexus 7000 Series device.

Supported Device Operating Systems

The Cisco Nexus 7000 Series device must be running the NX-OS operating system, which is used to perform the EPLD upgrades.

Updated EPLDs

Depending on the NX-OS release that you are using, the EPLDs that you download and reinstall can include newly updated EPLDs. Table 2 lists the updated EPLDs for each NX-OS release and the hardware that they affect. Table 3 lists all of the EPLD versions for the current release

.

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

---

Installation Guidelines

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

•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 system 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. On a system that has only one supervisor module, you can upgrade the active supervisor, but this will distrupt 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.

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 system modules, you must determine the NX-OS version that your system 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 device through the console port, an SSH session, or a Telnet session.

Step 2 Enter the show version command to verify that the device is using the expected version of the NX-OS operating system. The kickstart and system lines indicate the 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 system 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 1 to determine the amount of available bootflash memory, and see Example 2 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.4.0.1.bin

switch# attach module 5

switch(standby)#

Step 5 Copy the EPLD image file from the FTP or management server to the bootflash or slot0 memory in the active supervisor module by using the copy command. 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.4.0.2.img bootflash:n7000-s1-epld.4.0.2.img

Copy the EPLD image to the standby supervisor by using the copy command.

switch# copy bootflash:n7000-s1-epld.4.0.2.img 
bootflash://sup-standby/n7000-s1-epld.4.0.2.img

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

Upgrading EPLD Images

When you start upgrading the EPLD images for a module, NX-OS tries to list the current and new versions for each EPLD. If the module is installed and online, NX-OS reports both the installed and new versions of each EPLD, and where there is a difference, NX-OS will upgrade (or downgrade) to the new version when you confirm that the upgrade should occur. For a module that is installed but offline, NX-OS cannot determine the installed versions of its EPLDs so it upgrades all of the EPLDs for that module when you confirm the upgrade. For a module that is not installed, NX-OS displays an error message and does not upgrade the EPLDs.

Example 3 shows how NX-OS reports the current and new EPLD versions for a module that does not need EPLD upgrades. The current and new version numbers for each EPLD are the same.

Example 3 EPLD Version Comparison Report—No Upgrade Needed

EPLD                                Curr Ver    New Ver

-------------------------------------------------------

Power Manager                        5.3         5.3

Forwarding Engine                    1.6         1.6

Module 1 is upto date

Example 4 shows how NX-OS reports the current and new EPLD versions for a module that has EPLD images that can be upgraded. According to this report, each of the downloaded Linksec Engine EPLDs has a different version than the same EPLD on the module, so NX-OS will upgrade those EPLDs but will not upgrade the other EPLDs that have the same version numbers. If the new versions have a smaller version number compared to the current version, NX-OS will downgrade the versions.

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

•Upgrading the EPLD Images for I/O or Standby Supervisor Modules

•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 I/O or Standby Supervisor Modules

You can upgrade the EPLD images for an I/O module or standby supervisor module while the system is operational. If you need to upgrade EPLD images for a single supervisor system, 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 each module by entering the show module command.

Step 3 Begin upgrading the EPLD images by entering Y for yes.

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

Step 4 For releases 4.0(2) or earlier, 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). 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 system, power cycle the system.

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 system, all data traffic going through the system at the time of the power cycling is disrupted. This is not necessary for release 4.0(3) or later.

---

---

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

---

---

Upgrading EPLDs for the Active Supervisor Module

When you upgrade EPLDs on a system with only one supervisor module, data traffic on the switch will be affected when you reload the system after the upgrade. If you are upgrading EPLDs for a dual supervisor system, you can upgrade the standby supervisor while the system is operational as explained in the "Upgrading the EPLD Images for I/O or Standby Supervisor Modules" section.

To upgrade EPLDs for the supervisor module in a single supervisor system, follow these steps:

---

Step 1 Determine the slot number for each module by entering the show module command. The active supervisor is in either slot 5 or slot 6.

Data traffic on the switch will be affected!!

The switch will reload after the upgrade process.

Do you want to continue (y/n) ? 

Step 3 Confirm the upgrade by entering Y for yes.

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

The Cisco Nexus 7000 Series system will reload as soon as the upgrade occurs.

Step 4 For releases 4.0(2) or earlier, 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). 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 system, power cycle the system.

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 system, all data traffic going through the system at the time of the power cycling is disrupted. This is not necessary for release 4.0(3) or later.

---

---

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

---

---

Upgrading EPLDs for a Fabric Module

You can upgrade EPLDs for a fabric (Xbar) module while the system is operational as long as at least one other fabric module is operational.

To upgrade EPLDs for a fabric module, follow these steps:

---

Step 1 Determine which fabric modules are present on the Cisco Nexus 7000 Series device by entering the show module xbar command.

•CSCsq56222

Symptom: Dropped or corrupted packets in the egress direction on N7K 32-port 10GE module. Link is not dropped.

Conditions: Likelihood for drops or errors increase with higher traffic utilization. Rare event.

Workaround: None

Resolution: To be fixed in FPGA image version 1.8.

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, 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 systems 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 systems 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.
