12 Attachment: Technical Information
12.8.10 SPT - Single Path Through
The SPT (Single Path Through) ensures that in systems with only one reference clock, the generated signals
are distributed on the backplane.
The module has a microcontroller for registering the card in the system and managing the LEDs by evalu-
ating the signals displayed on the front panel. There are no configuration settings for the SPT via front panel
display and function keys of the system or in the web interface or CLI.
Status-LEDs
The status of the SPT is indicated by the four LEDs:
PPS:
red:
the signal was not provided to the
system by the receiver, yet.
green:
the signal is generated by the receiver
and distributed in the system.
10MHz:
red:
the signal was not provided to the
system by the receiver, yet.
green:
the signal is generated by the receiver
and distributed in the system.
Clock:
red:
as long as the receiver is not synchronized, yet.
green:
when the receiver is synchronized.
Status:
blue:
during the initialization phase.
green:
after initialization of the receiver.
Current Consumption:
40 mA
