Install CX4 in non-EMC rack

Generally, if you deselect the EMC 40U cabinet and select field install, you will get adjustable rails with the array.  Those rails will work in industry standard 4 post racks/cabinets.  As long as the Sun cabinet is a standard 4 post rack it should work fine.  If you order the array WITH an EMC cabinet, you will get NON-adjustable rails and its much more difficult to install those into a standard non-EMC rack, but it can be done if your rack has adjustable posts.

If you want to install the array into a 2-post Telco style rack that requires special rail kits.

Thanks a lot Richard.
