Card/Module Type Function
EHPM FTE Interface Module The EHPM FTE Interface module has 3
ethernet ports with RJ45 connectors and LEDs.
The backplane interfaces between the EHPM
and FTE Interface. The EHPM FTE interface
module does not use the Global Bus. The
EHPM FTE interface supports operation at 100
MHz.
ESD HAZARD
It is important that you wear a properly connected Electrostatic Discharge (ESD) wriststrap
while touching or handling the EHPM components.
Card/module illustrations
These cards and interface module are shown in more detail in the following figures:

Figure 5.2 EHPM FTE Interface Module (Front Panel)

Figure 5.4 Enhanced High-Performance Comm/Control Card (Front Panel)

Figure 5 High-Performance I/O Link Card (Front Panel)
Refer to these figures for the discussion of EHPM indicators, diagnostic switch, and power margin
jumper that follows.
Power indicators
When the EHPM is turned on, the
Power
indicator on each EHPM card and the EHPM FTE 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 Enhanced 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 EHPM is in the Alive state. It is lit
(not blinking) after the EHPM is loaded with the operating personality software, and enters the OK state.
When the EUCN FTE cables are in use, it is displayed by the indicators at the front of the EHPM FTE
Interface Module and under the front cover of the Enhanced High-Performance Comm/Control card.
The Transmit (
Tx
) indicator at the front of the EHPM FTE Interface module is an indication of EUCN
cable transmit activity.
The Link indicator at the front of the EHPM FTE Interface module is an indication of EUCN cable link
status.
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 Enhanced 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 displays a code that indicates the EHPM is in the Alive state, such as
Axxx.
In addition,
for EUCN, the 4-digit diagnostic display includes the UCN Node Number, FTE Device Index and the
