PA-MC-T3 Port Adapter Installation and Configuration

OL-2695-05

Chapter 1 Overview

LEDs

The PA-MC-T3 has one row of six status LEDs and one ENABLED LED. (See Figure 1-2.)

Figure 1-2 PA-MC-T3 LEDs

Table 1-2 lists port LED colors and indications.

After system initialization, the ENABLED LED goes on to indicate that the port adapter is enabled for

operation.

The following conditions must be met before the PA-MC-T3 is enabled:

• The port adapter is correctly connected to and receiving power from one of the following:

–

Catalyst RSM/VIP2 motherboard

–

Catalyst 6000 family FlexWAN module

–

VIP

• A valid system software image for the port adapter has been downloaded successfully.

LED Label Color State Meaning

ENABLED Green On Port adapter is enabled for operation.

ALARM Yellow On An alarm condition

is received on any configured T1 line or the

T3 link.

1. Alarms include: T1 loss of frame (LOF), T1 alarm indication signal (AIS), T1 yellow alarm indication, T3 loss of signal

(LOS), T3 AIS, and a T3 far-end receive failure (FERF) yellow alarm.

Blinking A port adapter boot failure has occurred.

2. This LED blinks momentarily during port adapter initialization.

LOOP Yellow On A T1 line or the T3 link is in a loopback state and is not enabled

for normal data traffic.

LOS Yellow On A loss of the received signal on the T3 link is detected by the line

interface unit (LIU) on the port adapter.

OOF Yellow On A DS3 out-of-frame condition.

AIS Yellow On An alarm indication signal is received on the T3 link.

FERF Yellow On A far-end receive failure signal is detected by the receiver.

3. When the OOF LED is on, the FERF LED is latched to its state prior to the out-of-frame condition; that is, it reflects the last

known state of the far-end receiver. When the OOF LED is off, the FERF LED reflects the live state of the far-end receiver.
