APC: Old firmware upgrade

Introduction

There may be cases when it is beneficial or even necessary to update a device’s firmware without using the web browser. It is possible to update the firmware using SSH and the fwupdate command. This article is a walk-through for getting the image onto the device and then flashing it.

Getting the image on to the device

The first step of flashing an image using shell is getting the firmware image onto the device. There are two easy ways to do this: to SFTP the image onto the device or to use wget from the device to download the image from an external source.

Step 1. Run WinSCP. Fill in the following fields in the window:

Host name – device’s IP address (default 192.168.2.66)
Username – admin
Password – device’s password (default: admin01)
Press Login to initiate an SSH connection with the device.

scp

Note: after pressing Login, a warning message may appear. To continue the login process, press Yes.
