Edge 340 firmware upgrade

This article provides instructions to upgrade the firmware on a Cisco Edge 340 device.


  • 1 USB flash drive.
  • Edge 340 firmware file from the device manufacturer.

Upgrading the Edge 340 Firmware

Follow the instructions below to upgrade the firmware:

  1. SSH into the Edge 340 device using either PuTTy (on a Windows PC) or Terminal (on a Mac) using the commands shown. Replace {deviceIP} with the IP address of the Edge device.


    Verify the correct IP address and root credentials for the Edge 340 with your network administrator:

    # ssh root@{device IP}
    # root@{device IP} password: aDMIN123#
  2. Use the mkdir command to create a /tmp/mnt directory:

    # mkdir /tmp/mnt
  3. Connect the USB drive containing the Edge 340 firmware file to the Edge 340 device. Use the blkid command to locate the USB drive. (usually /dev/sdxx, with xx being b1, b2 or c1, c2 etc.) For this guide, we will assume it is /dev/sdb1:

    # blkid /dev/sdb1: LABEL="USBDRIVE" UUID="62DA-9611" TYPE="vfat"
  4. Mount the USB drive:

    # mount /dev/sdb1 /tmp/mnt
  5. Locate the firmware file and copy the file to any location on the device. (In this example, we are copying the firmware file to apps/nexus2):

    # cp /tmp/mnt/{firmwarefile.bin} /apps/nexus2/{firmwarefile.bin}
  6. Navigate to apps/nexus2:

    # cd apps/nexus2
  7. Set execution permissions for the firmware file:

    # chmod a+x {firmwarefile.bin}
  8. Run the firmware upgrade:

    # su -c ./{firmwarefile.bin}
  9. In the event you are prompted for a password, key in the device’s root password (aDMIN123#). Please allow approximately 30 minutes for the upgrade process to complete:

    # password: aDMIN123#
