Storage Hard Disk Drive
The ATCA-F125 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 ATCA-F125 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
