Date Issued:	July 1, 2015
Summary:	Deprecation of "Drive Bay Kit Configurator" / New part numbers for drive bay kits.
Description:	Starting August 1, 2015 the "Drive Bay Kit Configurator" located at https://www.crystalfontz.com/products/select_kit.html will no longer be functional for ordering one of our Serial or USB displays (CFA533, CFA631, CFA632, CFA633, CFA634, CFA635, and CFA735) in a bracket or SLED. This functionality is being moved to the Customize and Add to Cart process when checking out. This will allow for further customization by our customers to better fit their needs. This change will eliminate the current "kits", but will add options not previously available such as pre-configured ATX functionality, and ALL the currently available interfaces will be orderable in a drive bay bracket or SLED. The new part numbers will have the bracket / SLED and overlay type as a PREFIX to the configured part number. The choice for bracket / SLED to a display order will be via the cart options. Our CFA835 displays were introduced with these configuration options. To see how the new options will look, and what the new part numbers will look like, please see one of our CFA835 parts: https://www.crystalfontz.com/cart/addtocart.php?product_id=2277&qty=1 NOTE: The SLED is only available for the CFA635, CFA735, and CFA835 products.
Reason:	As part of our continuous improvement process, we are integrating the ordering of displays in drive bay and SLED kits as part of the display ordering process.
Impact:	Drive bay kits in their current configuration will no longer be available.
Recommendation:	Place orders prior to 2015-08-01 for upcoming production needs via our website or by contacting our logistics department via email: sales@crystalfontz.com, or by calling 1-888-206-9720 (International call +1-509-892-1200). After the 2015-08-01, please contact our engineering department via support@crystalfontz.com to assist you with ordering your bracket / SLED kits.
Availability:	Starting 2015-08-01, the bracket and SLED options for our serial and USB display will be part of the ordering process for the displays
Price Change:	Pricing bracket / SLED configurations will reflect manufacturing costs.
