PA-A6 ATM Port Adapter Installation and Configuration

OL-2672-05

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.

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.
