Overview
- EN (Green): Indicates the service module has passed its self-test and is operational.
- AL (Yellow): Signals that the port is out of frame, indicating a potential issue with data transmission.
- CD (Green): Shows that the signal is present on the port, confirming successful connectivity.
- LP (Yellow): Denotes a loopback condition on the port, used for troubleshooting and network testing.
- AIS (Yellow): Alerts to an alarm on the DS3 transmission, signaling a potential issue that could impact network performance.
- FERF/RAI (Yellow): Indicates a remote failure at the far end of the connection, highlighting issues that may require attention.

Product Description
The SMX1T3E3 Cisco service module features a comprehensive set of LEDs for real-time status monitoring: EN (green for operational status), AL (yellow for out-of-frame ports), CD (green for signal presence), LP (yellow for loopback conditions), AIS (yellow for DS3 transmission alarms), and FERF/RAI (yellow for remote failures). It supports a range of Cisco IOS releases, including 15.2(4)M4 or later, 15.3(1)T2 or later, and 15.3(2)T1 or later, ensuring compatibility with contemporary networking environments. This module leverages these specifications to deliver reliable diagnostics and network status, facilitating efficient troubleshooting and system management.Key Feature for the SMX1T3E3
- What does a green LED on the EN service module indicate?
Green on the EN service module LED means the service module has passed its self-test and is operational. - How can you tell if a port is out of frame?
If the AL LED is yellow, it indicates that the port is out of frame. - What does a green CD LED signify?
A green CD LED signifies that the port is receiving a signal. - What condition does a yellow LP LED indicate?
A yellow LP LED indicates a loopback condition on the port. - What does a yellow AIS LED mean?
A yellow AIS LED means there is an alarm on the DS3 transmission. - What is indicated by a yellow FERF/RAI LED?
A yellow FERF/RAI LED indicates a remote failure at the far end of the connection. - Which Cisco IOS release introduced support for feature X?
Support for feature X was introduced in Cisco IOS release 15.2(4)M4 or later. - What is the minimum Cisco IOS release required for feature Y?
Feature Y requires Cisco IOS release 15.3(1)T2 or later. - At what Cisco IOS release does feature Z become available?
Feature Z is available starting with Cisco IOS release 15.3(2)T1. - How can one identify a service module's operational status through LEDs?
Operational status is indicated by the service module's LEDs: green on EN suggests normal operation, yellow on AL, LP, AIS, or FERF/RAI indicates specific issues.
Product Review
The Cisco SMX1T3E3 service module provides clear diagnostic feedback through its LED indicators, enabling efficient monitoring and troubleshooting of network status. Compatibility with Cisco IOS releases 15.2(4)M4 or later ensures support for a range of routing features and security updates. However, the presence of multiple conditions indicated by yellow LEDs, such as out-of-frame ports and alarm conditions, requires prompt attention and may indicate frequent manual intervention for optimal operation.
