Table 50 Connector J32, Management infrastructure signal descriptions
SAS-out These signal pairs connect to the SAS controller (LSI-1068) on ATCA-S201, ports 4, 5, 6 and 7.
SAS-in These signal pairs route to the Port3 of the AMC slots, sites 0, 1, 2 and 3
LAN0_MDIOxx GbE Management port. 10/100/1000BaseT signals. These signals route to a transceiver owned
by the Freescale PowerPC device.
LAN0_CTV 10/100/1000BaseT transformer Center Tap signal, which could be used to terminate center tap
of transformers, if they are placed on RTM. This signal is applicable if Ethernet PHY is located on
ATCA blade, while GE transformers are located on RTM.
LEDACT# LAN 0 (Management) activity indicator signal for LED (active low)
LEDLINK# LAN 0 (Management) LINK indicator signal for LED (active low)
UART_ RS232 Serial Signals, transmit, receive, clear to send, request to send, data terminal ready, data
set ready. These signals route to the Freescale PowerPC device.
