SyncSystem 4380A Frequently Asked Questions (FAQs)
Q1: How do I power up the SyncSystem 4380A?
A1: There is no "on/off" switch for the SyncSystem 4380A. To power up the unit, simply plug
the female end of the power cord (IEC 60320 C-14 inlet, 100-240 VAC, 45-65 Hz) into the AC
power supply module located at the rear panel of the chassis and the male end of the power
cord into an appropriately rated AC wall receptacle. If only DC power supplies are installed
(requires DC option in chassis), then use a 3 pin DC power supply connector (AMP #1-350346-0,
22-60 VDC).
When power is applied to the 4380A, the front panel will go through a self test and then the
4380A will begin booting up. 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, then the power supply without input power should have a red Status Indicator
and the unit's Alarm Indicator should be red.
The following 4380A front panel Power-On Self Test (POST) will occur even if the software flash
has been removed from the unit:
1. The Date/Time display will sequentially test each segment on each individual position
within the display.
2. One at a time, each position of the display will display the number 8 starting from the far
left and working to the right.
3. Each Light Emitting Diode (LED) below the Date/Time Display (Alarm, Sync, & Output) 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 Sync indicator. This
indicator will turn red, then green, then off.
4. The Date/Time display will then display "-9876543210" on the front panel.
5. Lastly, the Date/Time display will have a "-" in the center of each position in the display.
6. When the unit starts the application, the Alarm and Sync lights will turn Red. The
Outputs indicator will remain red until NTP is locked and the outputs are turned on.
To power down the 4380A, simply remove the input power sources from the two power
supplies.
Q2: How do I communicate with the SyncSystem 4380A?
A2: Operators are capable of communicating with the 4380A through an Ethernet LAN
connection or via one of the USB ports when using an adapter cable to access the command
port. Further details are provided by way of the answer to Question 4 in this list of FAQs.
