Ask Neadom: Inside the Sophos XG 750 Firewall – Unboxing and First Look

Introduction

What’s going on everybody? This is Neadom Tucker. Today, we’re going to look at the XG 750 from Sophos.
This is the mothership when it comes to their firewall product lines. It’s the largest appliance they sell.
We’re installing two of these for customers, so we’re going to take a look and show you what’s inside. Stay tuned.

Welcome

Hey guys, welcome back. I’m Neadom Tucker, owner of Kotori Technologies.
I’ve got over 20 years of experience in the IT industry, and today we’re going to take a look inside the box.
We’ve got the XG 750 from Sophos Firewalls. This is their top-of-the-line appliance.
It’s got all the bells and whistles. Let’s take a look inside.

Unboxing the XG 750

This is a big box. It’s heavy and solid.
These are double-boxed, so we’re opening the first box now.
Inside, we’ve got rack rails, power cords, and more rack rails.
We’re going to unbox this and see what’s inside.

Inside the second box, we find:

Quick Start Guide
LAN module instructions
Safety instructions
Sliding rack rail installation guide
Sophos orange console cable
USB modules
Rack ears and screws
Serial numbers for documentation
Optional feet (if not rack mounting, though we highly recommend you do)

The Appliance

Now let’s take a look at the actual unit.
Be careful—this thing is no joke and not cheap.
On the front, you’ll see it doesn’t ship with many modules. These are highly customizable.
Our customer purchased a 4-port 10-gigabit Flexi Port module.
There are two hard drives in a RAID 1 array, USB connections, and a Linux-based OS installer.

On the back:

Redundant power supplies
Fans
VGA connection
Power switch
Add-on card slot
8-port 1-gigabit interface card
Management interfaces
Flexi port module bays labeled A through H

Removing and Installing Modules

To remove a module, unscrew the latch and slide it out like a power supply.
Sophos builds these systems with care and precision.
We’re reinstalling the module now to ensure it’s secure during installation.

Powering On

Let’s power this beast on and see what it sounds like.
It’s loud—definitely server-room level noise.
We hit the red button to silence the alarm while it boots up.

Interface Overview

Once powered on, the system displays a basic menu.
Pressing Enter brings up the main menu:

System Info
Network
Firmware
HA (High Availability)

In the system menu, you can view:

Date and time
Uptime
CPU and memory usage
Logged-in users

In the network menu, you can view port configurations.
Ports A1 through A8 are listed, and then it switches to H1 through H4 for the Flexi Port module.
Management interfaces are also shown.

Installing the Flexi Port Module

We’re installing a 4-port 10-gigabit SFP+ module without bypass.
Bypass allows traffic to flow even if the firewall fails—this one does not have that feature.
Inside the module box:

LAN module configuration guide
Safety guide
Quality assurance slip

We’re installing this module into bay H.
After unscrewing the cover, we slide the module into place and secure it.
Once installed, we power the unit back on and verify the module appears in the interface.

Final Thoughts

That’s the Sophos XG 750 with the 10-gigabit SFP+ module.
