Introduction
1.1
Overview
The RTM-ATCA-736X-DD is a rear transition module (RTM) designed specifically to work with 
the Artesyn ATCA-736x processor blade family. The RTM features a two-port 1 Gb Ethernet 
controller, a four-port SAS controller and two removable disk cards called SAS Drive Carriers. 
The disk cards each hold one 2.5" disk, and fit wholly within the RTM thermal envelope to 
provide an environment for proper disk cooling. 
Functionally, the RTM-ATCA-736X-DD utilizes two PCI Express buses to connect with the 
Ethernet and SAS controllers. The Ethernet controller provides two 1000Base-T Ethernet 
connections using RJ45 copper media jacks on the RTM back panel. These ports are compatible 
with commodity off-the-shelf, non-proprietary CAT-5E or similar cables.
The SAS controller provides four SAS/SATA ports that each operates at 3 Gb/s. Two SAS ports 
route to the removable disks, and two SAS ports route back to the Zone 3 connector for 
additional storage expansion. For example, the front blade can add more storage by routing 
these ports to disks or to a SAS expander.
Finally, the RTM-ATCA-736X-DD includes numerous indicator LEDs and a modular 
management controller (MMC) with a hot swap notification mechanism to coordinate disk 
servicing the front blade OS. The MMC also performs intelligent monitoring and management 
tasks and conforms to the PICMG 3.0 and AMC.0 R2 specification.
