Sale of refurbished hardware

It is worth weighing up whether it makes more sense to buy new or used equipment. Refurbished products continue to work in exactly the same way for years to come so that users don’t have to make any compromises. Whereas the use of used equipment has a long-proven tradition in other industries (medicine, aircraft manufacturing, etc.) as well as in private life, the concept is still in its infancy in the IT sector.

Let us convince you of the countless advantages to be gained by using refurbished products. Ecology, saving potential and quality no doubt play a key role for you and your enterprise. Buy your refurbished hardware from us and you will also reap the following benefits:

Low prices

Refurbished hardware is much less expensive than new equipment. Profit from unbelievable saving potential.

Questions and answers about hardware sales

Why should I buy my products from Green IT Solution GmbH?

We have a wealth of expertise which we have gathered over fifteen years of trading new and used hardware. Among our customers are renowned enterprises and concerns which operate both nationally and internationally. Although you can of course purchase new network technology from Green IT Solution GmbH, we specialise in trading with used products. The reason for this is simple. After all, as a customer, you profit from the extremely advantageous conditions, without having to do without the quality of our premium manufacturers which include Cisco, Juniper, Fortinet, FireEye, Alcatel, Brocade and HP. Once we have professionally refurbished the relevant products, you will receive items which can no longer be described as used network technology. In fact, the equipment is comparable to new products. To underline the outstanding quality of our refurbished products, in addition, we offer you a 10 year warranty. However, by buying used hardware, you do not just profit economically. In fact, you are also making an important contribution to protecting the environment.

Which manufacturers are offered by Green IT Solution GmbH?

Our product range is based on the top manufacturers in the network technology sector. Primarily, this includes contemporary and innovative IT solutions from the following brands.


Cisco is seen as the global market leader in the IT industry. The US American company is primarily specialised in high-performance routers and switches. However, the product range essentially covers all solutions in the field of network technology.


After Cisco, Juniper Networks holds second place in the international leading manufacturers of network equipment. Their area of focus is clearly the manufacture of high-end routers. In the first instance, Juniper’s product range can be subdivided into switches, routers, SSL VPN, Wireless Lan, firewalls, application acceleration and Unified Access Control.


Until its merger with the American concern Lucent Technologies to become the new company Alcatel-Lucel, the French manufacturer Alcatel was regarded as the market leader in the field of optical networks as well as in high-speed Internet access. Apart from the already-mentioned high-speed network access, the specialities of the successful provider include multimedia networks, IP telephony as well as ATM/IP switches and routers.


What started as the Hewlett-Packard Company is, since November 2015, officially HP Inc. Here of course we are talking about one of the largest American manufacturers of printers and PCs. Founded in 1939, the company is located in Palo Alto, California. Apart from the excellent quality of its products, one of the reasons HP is at the centre of international attention is due to its comparatively environmentally-friendly production methods.


As a market leader in innovative network technology, including Fabrics solutions for IP storage, SAN and New IP networks, the Californian company located in San José has acquired worldwide fame. Thanks to the first-class quality and the high level of energy saving of its products, around 80 per cent of the „Global 1000“ enterprises use solutions from Brocade.


Fortinet is one of the leading experts for network security solutions in the world. Their core business is to provide network security platforms which are outstanding, above all, thanks to their peerless performance and innovation.  Another goal is the simplification of the IT infrastructure for demanding customers which, to a great extent, consist of data centres, operators, subsidiaries, companies and enterprises.


As an indisputable expert, FireEye specialises entirely in the creation of effective prevention and security measures against complex cyber attacks. This includes tracking down data leaks as well as other potential gaps in security – which make it easier for cyber criminals to get hold of sensitive information and misuse it for illegal activities. Whoever chooses FireEye is not just protecting their intellectual property in the best way possible, but is also ensuring that weaknesses do not arise in the first place. At its heart is the patented Multi-Vector Virtual Execution Machine, which records and evaluates potential threat data. This way, risks can be identified early on and, ideally, prevented as well.

Can I also buy new products from Green IT Solution GmbH?

Of course you can also buy new network technology from us. Thanks to our excellent sales network, here we are also able to offer you very good conditions. You decide whether you want to use new or used products for your project. Generally, in practice, we recommend to our customers that they combine used equipment with new network technology. In particular, using refurbished products makes sense for spare parts, which are stored as spares in case of emergency. In contrast, buying new parts is recommended when there are just not enough spare parts available on the market. This is the case, for example, when a new product has just been introduced and therefore is not yet available as a used or refurbished variant. If you have questions about this or require information, please do not hesitate to contact us. We are happy to advise you and help you find the right balance between new and used hardware.

Is equipment no longer offered by the manufacturer always available?

Even if the manufacturer has taken the product off the market and no longer sells it directly, this does not necessarily mean that the item can no longer be delivered. You will find numerous articles in our product range which are no longer offered by the manufacturer and are only still available as used equipment. Of course, the quality of the equipment you receive is the same as you would have received from the manufacturer – and beyond. After all, we offer a ten year guarantee for your used equipment. Get in touch with us if you are looking for a particular product or need advice.

I can't find the product I'm looking for in your shop. What can I do?

With more than 20,000 products offered by Green IT Solution GmbH, the shop only displays a fraction of the new or used products which we are able to offer you. If you can’t find the product you are looking for in our shop, get in touch with us anyway.
