Dell PowerFlex Appliance with PowerFlex 3.x Administration Guide

Upgrading the electronic programmable logic device (EPLD)

1. Start an SSH session to the switch.
2. Enter the following command to commit to persistent storage. In addition, copy the configuration to a jump server: copy running-config startup-config.
3. Determine the current running version, type show version module <number> epld.

   Wasps-N93180YC-TOR1-A# show version module 1 epld
   
   EPLD Device													Version
   -------------------------------
   MI FPGA																		0X4
   IO FPGA																		0X9

4. Check the contents of the bootflash directory to verify that enough free space is available for the image.
   1. Check the free space on the flash, type: dir bootflash:.
      Example command output:

      Usage for bootflash:// 1275002880 bytes used
      375902208 bytes free
      1650905088 bytes total

   2. Delete older firmware files to make additional space, if needed.
      NOTE:The Cisco Nexus 3000 and Cisco Nexus 9000 switches do not provide a confirmation prompt before deleting them.

      NOTE:The Cisco Nexus 3172 switch and Cisco Nexus 3132 switch do not require EPLD upgrade.
5. Using SCP, FTP, TFTP server, type the following to copy the firmware file to local storage on the Cisco Nexus switch:

   • Use below TFTP command to copy image.

     copy tftp://XXX.XXX.XXX.XXX/  n9000-epld.9.3.3.img bootflash:

   • Use SCP to copy image.

     copy scp://filescp@x.x.x.x//home/filescp/image/ n9000-epld.9.3.3.img bootflash:

6. To determine if you must upgrade, type show install all impact epld bootflash: n9000-epld.9.3.3.img.

   Wasps-N93180YC-TOR1-A# show install all impact epld bootflash:n9000-epld.9.3.3.img

   Module 1 EPLD upgrade is successful.

   NOTE:After the upgrade, the switch reboot could take 5 to 10 minutes. Use a continuous ping command from the jump server to validate when the switch is back online.
8. Using SSH, log back in to the switch with username and password.
9. Verify that the switch is running the correct new version, type:switch# show install epld status.

   Wasps-N93180YC-TOR1-A# show install epld status
