Refer to these figures for the discussion of HPMM indicators, diagnostic switch, and power margin
jumper that follows.

Power indicators

When power is applied to the HPMM, the Power indicator on each HPMM card and the HPM UCN
Interface module lights. The Power indicator is illuminated whenever 24 Vdc from the cabinet Power
System is present.

Status indicators

The Status indicator on the High-Performance Communications/Control card illuminates momentarily
after applying power. Internal test routines are executed upon applying power, and the Status indicator
remains on if the tests are successfully completed. The steady illumination of the Status indicator
signifies that no test failures were detected.
The High-Performance I/O Link Status indicator is not lit when the HPMM is in the Alive state. It will
light (not blinking) after the HPMM is loaded with the operating personality software, and enters the OK
state.
The UCN cables in use indicators are visible at the front of the HPM UCN Interface module (Rx-A and
Rx-B) as well as under the front cover of the High-Performance Comm/Control card (UCN A and UCN
B).
The Transmit (Tx) indicator at the front of the HPM UCN Interface module is an indication of UCN
cable transmit activity.
Refer to the "FTA Redundancy Indicators"subsection in the "Fault Isolation" section. for additional
information on the status indicators.

Diagnostic display

The 4-digit Diagnostic display at the front of the High-Performance Communications/Control card
(below the upper extraction lever) provides additional status information as well as error code
information if a failure occurs. After power is applied and the internal test routines have completed
successfully, it will display a code that indicates the HPMM is in the Alive state, such as Axxx.
