Chapter 1 Overview
LEDs
The PA-A6 complies with the environmental specifications listed in Table 1-1.
LEDs
The PA-A6-OC3MM/SMI/SML port adapters have four status LEDs and one ENABLED LED. (See
Figure 1-6.)
Figure 1-6 PA-A6 LEDs—Horizontal Orientation
The PA-A6-E3 and PA-A6-T3port adapters have three status LEDS (RF CELLS, RX CARRIER, RX
ALARM). See Figure 1-4 and Figure 1-5.
After system initialization, the ENABLED LED goes on, indicating that the port adapter has been
enabled for operation.
The following conditions must be met before the PA-A6 is enabled:
• The port adapter is correctly connected and is receiving power.
• A valid system software image for the port adapter has been downloaded successfully.
• The system recognizes the port adapter.
If any of these conditions are not met, or if the initialization fails for other reasons, the ENABLED LED
does not go on.
Table 1-2 lists LED colors and function.

LED Label Color State Function
ENABLED Green On PA-A6 is enabled for operation.
RX CELLS Green On PA-A6 has received an ATM cell.
RX CARRIER Green On PA-A6 has detected a carrier on the receiver cable. For a
fiber-optic interface, this means that the light is detected, and
a valid image is detected.
RX ALARM Red On PA-A6 has detected an alarm.
TX CELLS Green On PA-A6 has transmitted an ATM cell.
