The Sun Netra CP3240 switch supports RTMs through ATCA Zone 3 connectors (see TABLE 2-2). The Sun Netra CP3240 switch was designed to support multiple RTM designs.

4 Fabric 10Gigabyte, 2 Base 10Gigabyte, 2 Base 1Gigabyte, AMC I/O, and management ports are run to the RTM. Several voltage rails are supplied, and all of the signals needed to design an ECN002 compliant RTM are present.
