Cisco IOS XE Operating System
Cisco IOS XE Software provides a modular, Linux-based architecture that separates control and data plane functions for enhanced stability and performance. The operating system's universal image includes all features activated through licensing, simplifying software management and deployment. Benefits include superior scalability through separation of routing functions from packet forwarding, comprehensive security with regular updates and patches, and extensive protocol support for diverse networking requirements. Organisations should note that advanced features require appropriate licences, and the learning curve may be steeper for administrators unfamiliar with Cisco command-line interface compared to simplified management platforms.
Cosmetic Condition Grades
Excellent Grade network equipment shows evidence of very light previous use with minimal wear on housing and external surfaces. Units may have very minor scuffing or minor abrasions associated with light standard use, with no deep scratches, cracks, paint chips, or broken/missing pieces.
Good Grade network equipment is fully tested and fully functional but may feature light scratches on the external body and more visible unit housing wear than Excellent grade units. Good grade routers may feature one or several small dings or dents on covers and/or small paint chips on the surface.

Good value and great quality
Fantastic service
I was looking for an in-expensive all-in-one solution for my home office to replace my existing desktop and monitor. I found this EliteOne 800 on reboot IT for under $200. I wasn't sure what to expect. It arrived within two days!!!! I upgraded the RAM, replaced the HDD and installed Windows 11. This is unbeatable value and was the cheapest price online. Coupled with a 3-month warranty, Reboot IT are by far the best online refurbished retailer I have used. Awesome!
Great service. Product in great condition and exactly what i want. I wanted this for a specific purpose but i dont need to spend $900 on a new one.
Excellent work
exactly as described and works well , just like the staff down there. 10/10
Very happy, thank you
Just having trouble greeting it linked to the internet otherwise it’s okay.
Fair tech for price, good specs for era, serves the purpose. The black keyboard is an interesting rubber like texture clearly by design to pad the screen and avoid the keyboard touching. Screen is great. Still looking for magic formula to enable computer use in the bright bright sunshine. Keyboard taps are loud for someone who likes silent touch. The perfect PC has to exist, like build a bear.
The laptop was sold with a warning about worn keycaps. In fact they had been obviously vandalised (ex school laptops, perhaps?). The keyboard worked fine, and the rest of the laptop too. I'm using it as a file server, so I don't need the keyboard much. So very pleased, and also pleased with reboot-it's service - as always, excellent, and quick responses to any queries.
Great way to buy a computer
Always good, sometimes a little slow and steady, but always good :-))
I needed a quick cheap windows 11 capable notebook.
RebootIT had a bunch of 2nd hand stuff advertised.
This Dell 5310 was one of them, at the right price and spec.
It works brilliantly, although its not the prettiest notebook I've seen.
RebootIT were up front about the condition though, so I still got a better notebook than I expected.
Perfect thin monitor for my purposes.
Unit was in excellent condition as described. Dispatch was priority and prompt.
Just plain good old fashion service. Nothing more to say I guess
