Agilent Technologies J3919A, J3972A manual 10Base-T/100Base-TX Telemetry Interface Status LEDs

Introduction

Probe Overview

Status LEDs

Your probe has status LEDs for the base hardware configuration (the 10Base-T/ 100Base-TX telemetry interface), for the OC-3 ATM interface, and for the optional Token-Ring telemetry interface.

The following sections cover the possible status LEDs on your OC-3 ATMProbe:

10Base-T/100Base-TX Telemetry Interface Status LEDs

The status LEDs for the 10Base-T/100Base-TX telemetry interface are visible on the front and back of the probe. Figure 1-3 on page 11 shows the LEDs on the front of the probe and Figure 1-4 on page 12 shows the LEDs on the back of the probe.

The ~ Line On, Activity, and Fault LEDs are on the front of the probe.

On the back of the probe, there are LEDs associated specifically with each interface and a Power LED. The 10Base-T/100Base-TX telemetry interface has LEDs for Activity, Link and Collision.

Refer to the following list for information on how these LEDs work:

~Line On or Power. This green LED is turned on when the probe is receiving power.

Activity. This green LED is turned on when data is being received from the Ethernet telemetry network or transmitted by the probe. When flashing, the frequency shows the amount of traffic. During periods of steady traffic, it may appear to stay on solid.

Link. This green LED is turned on when the probe is attached to a 10Base-T/ 100Base-TX network.
