Cost-reducing OEM Upgrades

An OEM upgrade with GTC can help you reduce costs by acquiring your pull-out system and spares inventory.

In order to assist the evaluation of your surplus systems, you must:

  • List all installed hardware in the panel
  • List all spares in stock
  • List all damaged / failed hardware in stock
  • Take pictures where possible
  • Offer a full description of the equipment available
  • State when the parts will be available for purchase.

If you own any faulty MKVIe I/O packs (version H1A) or controllers (version UCSA), GTC is interested in buying them or providing credit for any future purchases.
