Edge 340 Firmware Upgrade
Overview
This guide outlines the steps to upgrade the firmware on the Cisco Edge 340.
Pre-requisites
- Cisco Edge 340 device
- 1 USB flash drive containing the Edge 340 firmware file
- 1 firmware file (for use with the USB flash drive)
Upgrading the Edge 340 Firmware
Step 1
SSH into the Edge 340 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 with your network administrator regarding the correct IP address and root credentials for the Edge 340).
# ssh root@{device IP}
# root@{device IP} password: aDMIN123#
Step 2
Use the mkdir command to create the /tmp/mnt directory.
# mkdir /tmp/mnt
Step 3
Connect the USB drive containing the firmware file to one of the USB ports of the Edge 340. 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/sde1.
#blkid
/dev/sdb1: LABEL="USBDRIVE" UUID="62DA-9611" TYPE="vfat"
Step 4
Mount the USB drive.
# mount /dev/sdb1 /tmp/mnt
Step 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}
Step 6
Navigate to apps/nexus2.
# cd apps/nexus2
Step 7
Set execution permissions for the firmware file.
# chmod a+x {firmwarefile.bin}
Step 8
Run the firmware upgrade.
# su -c ./{firmwarefile.bin}
Step 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#
