4.6.5 BCM84740 Status
The LASI signal from the BCM84740 is individually connected to the RTM FPGA to allow it
to be monitored by software. The LASI signal can also generate an interrupt to the front
blade. Refer to
GPS Connectors on page 67
for further details.
4.6.6 Fabric QSFP+ Connection
The QSFP+ cage accepts industry standard QSFP+ optical modules. It also accepts
QSFP+ copper and optical direct-attach cables. The site is designed to support power level
2 modules which are rated up to 2W (refer to the
ATCA-F140 Installation and Use Manual
for a list of QSFP+ devices tested with this product). The QSFP+ connector assignment for
the 40Gbps serial interface is described in
Table 4-9
.
