When the HDSL4 powers up, the following occurs:
1 The STAT LED briefly light red, then yellow, indicating that the power is on and
that the self-test diagnostics are beginning. The remaining LEDs momentarily
light yellow, then turn off.
2 The front-panel LEDs light as follows upon successful completion of the self-test
diagnostics:
•
STAT - Green
•
RMT ALM - Off (or yellow when the HDSL4 LOSW/BER LED is red)
•
LPBK - Off
•
DS1 LOS/BER - Off (or red, if DS1 is absent)
•
B8ZS - Off when set to AMI; green when set to B8ZS
•
HDSL4 Loop 1 and Loop 2 - Momentarily solid Red, then flashing green
during loop activation, then solid green
3 If all LED indicators respond as described, press the LMPTST switch on the APU
to verify that all LEDs on the front panel of the line unit light yellow. This
indicates that the LEDs are functional.
