Hi All ,
We are planning to go with 8.4.2 version on nexus 7010 with cold reboot from 6.2.20 and would like to know why N7K-SUP2E is not mentioned under supported hardware as we are seeing only SUP2 Module .
Table 3 Supported Modules with the FPGA in Cisco NX-OS Releases 8.4(2)
Cisco Nexus 7000 Supervisor 2 | PMFPGA | 38.000 |
IOFPGA | 1.013 | |
Cisco Nexus 7700 Supervisor 2E | PMFPGA | 22.000 |
Cisco Nexus 7700 Switch Supervisor 3 Enhanced Module | PMFPGA | 22.000 |

Installation/Upgrade Guidelines
Note
By default, you cannot downgrade EPLD images when you downgrade the NX-OS software release because the EPLD images work with down level versions of the software. For this reason, we do not recommend downgrading EPLD images.
The allow-downgrade option is not supported and it is not available as a command in Cisco NX-OS Release 8.0(1).
You can upgrade EPLDs using CLI commands on the Cisco Nexus 7000 Series switch. By default, EPLD images are not downgraded when you downgrade the NX-OS software release because each EPLD image works with older releases of the software. >>>> if I want to roll back to 6.2.20 then NO need to downgrade EPLD image to same version , was it Right ? Will all modules funtion with EPLD version of n7700-s2-epld.8.4.2.img even though we revert back to old image ie 6.2.20
Below Two statements are confusing a lot .
Statement 1 :
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 images and be sure that you have one of the following EPLD image files:
Cisco NX-OS Release 8.3(1):
n7700-s2-epld.8.3.1.img n7700-s3-epld.8.3.1.img
Statement 2 :
Note- For Cisco NX-OS Release 6.2(10) and later releases it is recommended to perform EPLD upgrade with the current image (version matching the NX-OS release you are upgrading to) before upgrading to Cisco NX-OS Release 8.3(1).
–
---> Does this means first I need to upgrade n7000-s2-epld.8.4.2.img and after the reload the nexus 7010 with 8.4.2 , was it correct ?
Usually we are following upgrade OS to newer version and then upgrade EPLD images , but here what is the exact meaning of above statement ?
- For releases prior to Cisco NX-OS Release 6.2(10), you need to first upgrade to Cisco NX-OS Release 6.2(10) or later releases and perform EPLD upgrade with the current image (version matching the NX-OS release you are upgrading to) before upgrading to Cisco NX-OS Release 8.3(1).
EPLD upgrade :
Note EPLD and software images for a chassis with Supervisor 2 and Supervisor 2E have “s2” in the image name.
Example 4 Installing EPLD Images in Parallel for Switches with Supervisor 2 or Supervisor 2E Modules
All installed modules with one module upgraded at a time | install all epld epld_image |
All installed modules with the I/O modules upgraded in parallel | install all epld epld_image parallel

Many Thanks ,
