More details from JSI (www.johnsonsystems.com):
The new products are built around the existing and proven CD-3000 hardware and software and feature a new backplane and metal/chassis that facilitate a quick easy installation into existing compact rolling racks in minutes.
Both models feature all the advanced capabilities and “green” power features of other CD-3000 models and offer an optional Ethernet node. The new systems are ETL listed and comply fully with UL508 and CSA22.2 No 184 electrical safety approvals.
