Introduction
ATCA-MF106 Installation and Use (6806800M62B) 33
The ATCA-MF106 consists of the dual ATmega IPMC as a front-end to the IPMB in the shelf, and
the "Service Processor" based on a PowerQUICC, which provides the management functions.
The ATCA-MF106 is designed for redundant operation in AdvancedTCA shelves. Usually, two
ATCA-MF106 shelf managers are deployed in one shelf, one of which takes the role of active
ATCA-MF106, the other acting as standby ready to take over in case of failure of the active one.
Redundant channels for heartbeating and checkpointing between the two ATCA-MF106 are
provided.
The ATCA-MF106 shelf manager supports the following components:
 Freescale’s MPC8306S PowerQUICC processor with embedded PowerPC core
 ATmega128L (master) and ATmega8L (slave) micro-controllers from Atmel
 64 MB SDRAM memory
 64 MB redundant boot and user flash
 Dual redundant IPMB interface
 Two 10/100 Mbps Ethernet interfaces to the rear connector and one 10/100 Mbps
Ethernet port to the face plate
 Power brick supplying 3.5 A at 3.4 V (conventionally referred as 3.3 V)
 Two serial (differential) ports to the rear connector
 Local temperature sensor
 Block transfer interface through the FPGA
 LED indicators
 I

C interface, analog inputs and digital I/O from ATmegas to support shelf specific
functions
 Rear connector to the backplane (2 mm connector)
 MicroSD memory module
