Update the Switch's Firmware

To update the switch's firmware, you will need to copy the upgrade file to a USB drive and connect it to the USB port on the rear of the switch.

Guide available here.

Download the Firmware

Firmware upgrades are available for download from Aruba without a licence key. An account is required. Aruba does not allow users to make accounts with public email providers (gmail, hotmail, etc.), so you will either have to use a different email provider for your account or try to find the file elsewhere on the internet. For posterity, the sha256sum of the latest firmware upgrade avilable as of Jan 24, 2023 is as follows.

ArubaOS_MAS_7.4.1.9_62608: 613abae502736c7c7ac2a0548edf506280d2afb8d2762db784ffa68f5cd6c52c

Install the Firmware

From the switch's console, login and escalate your privledges.

(ArubaS2500-48P-US)

Then, install the firmware using the copy command.

Connecting to the Switch

Console

The Aruba S2500 has a micro USB port on the back which exposes a serial interface that can be used to manage the switch.

To connec to the serial interface you will need a computer, a micro USB cable, and a serial application (here we are using screen).

1. Connect the USB serial port on the back of the switch to your computer
2. Connect to the serial port with screen
   • sudo screen /dev/ttyUSB0 9600 (replace ttyUSB0 with the device node your system assigns to the switch)
3. Login with the default username and password
   • username: password
   • password: forgetme!

You should now be dropped to a shell that looks like the below

Ethernet (broken)

The Aruba S2500 provides a Web UI that can be used to configure the switch.

The WebUI forces HTTPS by default and the ciphers supported are not permitted by most modern browsers. You can enabled outdated ciphers in your browser which will enable you to sucessfully connect, but the WebUI may still fail to display.

To connect to the WebUI

1. TODO: enable the Quick Setup WebUI via the front panel menu
2. Connect an ethernet cable between your device and one of the 1GbE port on the front of the switch
3. On your machine, assign the interface a static IP with the follow configuration
   • IP: 172.16.0.2
   • Subnet Mask: 255.255.255.0 or /24
   • Gateway: 172.16.0.1
4. Connect to http://172.16.0.254 in your browser.

You should now have access to the WebUI.
