Storage Hard Disk Drive; Telecom Clocking - SMART Embedded Computing ATCA-F125 Assembly, Installation And Use

Functional Description
4.10.3

Storage Hard Disk Drive

The Product-ShortName provides a SATA connector and mounting features to install a 2.5"
SATA hard disk drive on the board. This HDD can be used to store system management
data, configuration data, and boot images for the service processor or the PrAMC. An
80Gbyte extreme duty drive or equivalent may be installed to support "enterprise class"
features, like permanent operation (24/7) and extended temperature range. The HDD can
be accessed by either the service processor or the PrAMC processor, depending on the
state of the on-board SATA mux. The mux may be controlled the service processor or the
IPMC through registers in the FPGA. By default, the mux will be configured to connect the
SATA drive to the service processor.

Telecom Clocking

The Product-ShortName supports an optional telecom clocking subsystem that is
responsible for the generation and distribution of traceable telecom clocks per use
throughout the local shelf and up to five connected extension shelves. Specifically, the
following key features are provided:
T0 and T4 PLLs for the generation of T[0] system clocks and a T[4] SSU clock

Dual T1/E1 ports to allow reception of redundant T[3] BITS/SSU clocks

Stratum 3 oscillator

Generation of a traceable clock

Routing of telecom clocks to AMC site
