Many network equipment resale companies claim they test your products extensively. If you go through a secondary market to purchase used network hardware, make sure your products have gone through the following steps comparable to what Network Liquidators offers:

1. When a piece of networking equipment is first received within the facility, it should be first subjected to a physical inspection to ensure no damage was incurred during shipping and handling.
2. It is then required that all internal and external serial numbers match, and all manufacturer labels and markings are intact. Any devices found with these deficiencies should be returned to the seller.
3. All units that do not have their tamper stickers intact, or are broken, should be opened and heavily scrutinized. If the main board or other internal components are missing hardware, the device should be returned to the seller or completely refurbished by certified technical engineers.
4. If a piece of network equipment has any repairable minor damage to the case or has missing screws or mounting brackets, we will fix and/or replace those pieces or parts.
5. All network equipment should be powered and run at all input voltage capabilities that the device can maintain.
6. All network products should be upgraded to the latest diagnostic software and tested at the highest level possible.
7. All network hardware should be allowed to warm up to normal operating temperature before any further diagnostics are performed. This helps in finding any thermal problems the device may have.
8. If the network equipment has the ability to run internal diagnostics they should be performed. It’s beneficial to a customer if all internal diagnostic results are recorded and a copy is included with the unit when purchased.
9. Any empty chassis we acquire should be populated to capacity with known functional blades to ensure all slots, power receptacles, and connectors are functional.
10. All hot swappable cards, power supplies, and modules should be tested to ensure they do not leave you with down time in the event you ever need to change a faulty component. Even a fail-over device should be tested.
11. All network switches should have every port individually tested to ensure they operate at optimal and peak performance.
12. All redundant systems should be put through fail over tests to verify reliability.
13. All network equipment should be configured and tested under real conditions to insure proper operation. This includes all layer 2, 3, and 4 protocols that the device is designed to support.
14. Once a piece of network hardware passes all diagnostic steps, it should be thoroughly cleaned and packaged for stock.
15. For accuracy, any device that has been in stock should be rechecked prior to shipping when it is selected to fill an order.
16. If a network unit from stock is updated with a different operating system, additional diagnostic tests must run to include a new test results included with the unit.
17. Finally, All products should be professionally packaged in either the original manufacturers boxes or with our with a state of the art packaging system since delicate systems are being transported.

With these 17 major steps in play, there is no reason anyone should expect any device from not working or being damaged during the shipping process. No one wants to go through the hassle of doing a return in any industry. Therefore, buying equipment from reputable resellers is that much more important.
