2 Installation
The ATS-6511 provides a number of features which may require additional setup and this section
provides a guideline for the basic setup. After completing this section, the ATS-6511 will
produce timing outputs to the coarse calibration accuracies specified in Appendix A. The ATS-
6511 is designed to be quickly and easily integrated with other system components. Just a few
steps are required in setting up the system so that it will begin producing accurate timing outputs.
In order to set the system up, users will need to power up the system and set up communications
in order to have access to the system command port. The only inputs required for operation of the
ATS-6511 are at least one power source and one fiber optic input sourced from a 4372A/4372A-T
installed in an ATS-6501 with revision 3.6.3 or newer software.
2.1 Powering on the ATS-6511
Apply power to the system by supplying input power to at least one of the two power supplies.
When power is applied to the ATS-6511 the front panel will go through a self test and then the
ATS-6511 will begin booting up.
Note:
If power is applied to both power supplies the Status Indicator on the front panel of both
power supplies should be green. If power is applied to only one of the two supplies the power
supply without input power should have a red Status Indicator and the unit’s Alarm Indicator
should be red.
Note:
The ATS-6511 front panel Power-On Self Test (POST) will occur even if the front panel
software flash is removed.
A.
The Date/Time display will sequentially test each segment on each individual position
within the display.
B.
One at a time, each position of the display will display the number 8 starting from the far
left and working to the right.
C.
Each LED below the Date/Time Display (Alarm, Oscillator Locked, Input A, Input B, &
Outputs Enabled) will be turned on one at a time starting from the left to right. As each
LED is tested it will be green, then red, and then turn off with the exception of the Input
A indicator, this indicator will turn red, then green, then off.
D.
The Date/Time display will then display “-9876543210” on the front panel.
E.
Lastly the Date/Time display will have a “-“ in the center of each position in the display.
F.
While the ATS-6511 is booting up and waiting for the internal oscillator to lock the Osc
Lock, Input A, and Input B LED indicators on the front panel below the Date/Time
display should be Red and the bars in the display after the POST will move to the top,
then center, then bottom and then go out. This display will repeat cycling the bars on the
Date/Time display as long as the unit is not tracking one of the input fiber signals. Once
the unit obtains the date/time from the fiber input (A or B) the Input A and/or Input B
LED will turn green, the Osc Lock light should turn green, the front panel will begin
displaying the present Date/Time, and the Outputs Enabled indicator will turn green
within ~2 minutes.
Note:
As the ATS-6511 warms up, the Oscillator Lock indicator should turn green within ~5 minutes after the system is turned on
and the system locks to one of the Fiber inputs. The Alarm light may stay on until the Outputs are enabled. This is normal and does
not indicate there is a problem with the unit. When the unit has locked the OCXO to one of the fiber inputs, the outputs will be
enabled and the Outputs Enabled LED will turn green within ~2 minutes.
