IBM 4986B LanProbe manual Status LEDs

Introduction

LanProbe Overview

Status LEDs

The status LEDs are visible on the front of LanProbe. Figure 1-3 shows the orientation of the LEDs on the front of LanProbe.

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

Link. This green LED is turned on when LanProbe is attached to an 10Base-T network.

Collision. This yellow LED is turned on when LanProbe detects collisions on the network.

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

Fault. This yellow LED is turned on when LanProbe needs to be reset, repaired, or replaced or when new firmware is downloaded. The Fault LED is normally on during the power-on self-test, but turns off after a successful self-test or when a cold or warm start is completed. The Fault LED will blink when a collision is detected on the network.
