SDU-2000e Turn-Up Procedures

Clock Module 3E – The POWER LED turns green when power is applied to the
unit and stays green. STATUS LED blinks green and amber for approximately 10
to 15 seconds and then stays green. The SELECTED LED turns green on the
selected clock module after the ACQUIRE LED turns green. The WARMUP LED
turns amber for approximately 30 seconds to 20 minutes then turns off and
ACQUIRE turns green. The ACQUIRE LED stays green until the module locks
onto a signal (10 to 15 minutes); then the LED turns off. The LOCKED LED turns
green and stays green.
Communications Module – The POWER LED turns green when power is
applied to the unit and stays green. The STATUS LED blinks green and amber for
10 to 15 seconds and then stays green. The –48V POWER LEDs A and B turn
green to indicate that the power supplies are connected. If one of these LEDs are
amber, the polarity of that power connection is reversed and needs to be
switched. The three ALARM LEDs clear after approximately 1 minute. After
initialization, if there are any alarms, it takes approximately 30 seconds to
register and the ALARM LED turns amber. The ETHERNET LINK LED blinks
green for approximately 30 seconds and stays green.
Input Module – The POWER LED turns green when power is applied to the unit
and remains green while the system is powered up. The STATUS LED blinks
green and amber for approximately 10 to 15 seconds and then stays green. The
PORT 1 REF LED blinks for approximately 5 to 10 seconds and turns green for
the reference input and off for the others. The INPUT LED blinks for 5 to 10
seconds and turns green for every valid input or amber for invalid inputs.
Output Module – The POWER LED turns green when power is applied to the
unit and stays green. The STATUS LED blinks green and amber for 10 to 15
seconds and then stays green. The SOURCE LED turns green for the source
clock, amber for an enabled clock that is not present and off for an enabled clock
that is present (but not the source clock).
SDU-2000e Turn-Up Procedures
This section describes the procedures for powering up the SDU-2000e system and
bringing the system on-line after completion of the system installation. After
completing the turn-up procedures, perform the tests in
2000e, on page 124, to ensure that the system is functioning properly.
SDU-2000e Power Control
The SDU-2000e expansion chassis is not equipped with a Power switch. Power to
the SDU-2000e is controlled by two external power supplies that provide
–48/60 VDC to the SDU-2000e main chassis (A-BUS and B-BUS) at connectors
J101 and J102. To power-up the shelf, install the fuses and/or turn the power on to
both power supplies.
