SAM1411 Installation and Use (6806800M91B) 25
Introduction
1.1 Overview
The SAM1411 is a shelf manager board to be used in the AdvancedTCA systems. It plugs into a
dedicated shelf management slot of an AdvancedTCA system. The SAM1411 performs the
system monitoring, control, and management functions of the entire shelf. It provides
management for up to 16 AdvancedTCA front blades, fans, power entry modules (PEMs), alarm
modules, and shelf FRU info modules that are present in an AdvancedTCA system. It is
designed for redundant operation in AdvancedTCA shelves. Two SAM1411 are deployed in one
shelf. One takes over the role of active shelf manager and the other one acts as standby shelf
manager, which is ready to take over in case of a failure of the active one. Redundant channels
for heart beating and check pointing between the two SAM1411 are provided to support
failover.
The shelf manager consists of hardware (payload and shelf management controller) and
software.
For information of the software, refer to the System Management Interface Based on HPI-B
(Centellis 31kX/4100/2000/4410) User’s Guide.
The SAM1411 provides the following interfaces:
 Motorola MPC8306S PowerQUICC processor with embedded PowerPC core
 Atmel ATmega2560 (master) and ATmega168 (slave) micro-controllers
 64/128 MB SDRAM memory
 64 MB boot and user flash
 Dual redundant IPMB interface
 Two 10/100 Mbps Ethernet ports to the rear connector
 One 10/100 Mbps Ethernet port to the face plate
 Two serial ports to the rear connector for heartbeat with the redundant SAM1411
 One serial port to the rear connector, for configuration and diagnostic purposes (routed to
the Alarm Display Panel)
 64 MB redundant boot and user flash for recovery
 SPI bus to MicroSD memory module for storage
 I2C to 512K EEPROM for OS environment variable data
