Edge 340 firmware upgrade

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

Prerequisites

Follow the instructions below to upgrade the firmware:

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.
Note

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#
```
Use the mkdir command to create a /tmp/mnt directory:
```
# mkdir /tmp/mnt
```
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"
```
Mount the USB drive:
```
# mount /dev/sdb1 /tmp/mnt
```
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}
```
Navigate to apps/nexus2:
```
# cd apps/nexus2
```
Set execution permissions for the firmware file:
```
# chmod a+x {firmwarefile.bin}
```
Run the firmware upgrade:
```
# su -c ./{firmwarefile.bin}
```
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#
```
