ATCA-7480 Installation and Use (6806800T17A) 92
4.13 Control Logic
The blade provides control logic for specific functions, which includes:
 Payload power supervision and sequencing
 Payload resets
 Multiple HW interfaces between payload and IPMC
 Support for sensors as required
Any control circuitry based on programmable logic whether intended for payload supervision
or as part of the payload is remotely upgradeable. Crisis recovery circuitry is provided to
prevent board lock-ups as the result of a failed remote upgrade of the board control logic.
4.14 Front Board Faceplate
The blade's faceplate provides the following interfaces and control elements:
 Two USB 2.0 ports
 Two 10/1000/1000Base-T Ethernet ports
 Serial console port to connect to either payload or IPMC serial I/F
 Recessed reset button
 Out of Service, In Service, Attention, and Hot Swap LEDs
The blade design provides the possibility to cover unused faceplate elements like LEDs or push
button behind a custom overlay foil.
4.15 Faceplate Serial Interfaces
The ATCA-7480 has two serial interfaces. They are fully compliant to industry standard 16550
asynchronous communication controllers. The two Serial line interfaces #1 and #2 are
integrated in the Intel DH8900CC PCH and routed to the on-board FPGA, which distributes
them to either Faceplate, RTM, or IPMC for SOL. The serial line interfaces support baud rates up
to 115200 kbps through a programmable baud rate generator.
