ATCA-F140 Series Installation and Use (6806800M67S)
Functional Description
Functional Description
Each QSFP+ module's I
2
C signals are routed to the corresponding BCM84740 PHY. The
service processor uses these I
2
C interfaces, accessed through the PHY management port,
to read the module's on-board EEPROM information to determine type and vendor specific
information. QSFP+ status and control registers can also be accessed through the I
2
C
interface.
The ATCA-F140 blade is designed to be compatible with QSFP+ modules up to Power
Level 2, corresponding to a maximum power of 2W each.

AMC Bay
The ATCA-F140 provides one AMC bay to support a processor AMC as an application
processor. The slot is connected by an AMC type B+ connector and supports a midsize
single width PrAMC module. The PrAMC has access to an on-board SATA drive and to a
dual Gigabit Ethernet controller through the AMC.0 ports. The IPMC sets a control output
pin during E-keying configuration to control the direction of a Pericom PI2EQX3421 SATA
mux, which determines whether the service processor or the PrAMC will have access to
the SATA hard disk drive. For debug purposes, the SATA mux control from the IPMC is
routed through the FPGA so that the SATA mux control can be manipulated by the service
processor through the FPGA.
The ATCA-F140 routes AMC ports 8-11 directly to the RTM for support of PCI Express
controllers on future versions of RTMs.
