LED Operation
The McBasic 10/100 features several diagnostic LEDs per port (see illustration above).
The LED functions for the McBasic 10/100 are:
Port LED Definition
LNK Glows green when a twisted pair link is established.
ACT Glows yellow when data is detected on the port.
100 Glows yellow when 100 Mbps data is detected on the
port.
LFD Glows green when Link Fault Detection is enabled. This
feature is available only when force 10 or force 100 is
enabled.
AN Glows green when Auto Negotiation mode is enabled.
Twisted
Pair port
PWR Glows green when unit has power.
100 Glows yellow when 100 Mbps data is detected on the
port.
ACT Glows green when data is detected on the port.
Fiber port
LNK Glows green when a fiber link is established.
NOTE
Before either LNK LED will glow solid, the twisted pair and fiber optic cables must be
connected and the twisted pair crossover/ pass-through switch set correctly.
Installation Troubleshooting
During installation, first test the fiber and twisted pair connections with all
troubleshooting features disabled, then enable these features (if desired) just before
final installation. This will reduce the features’ interference with testing.
When working with units where the features cannot be disabled, both the twisted
pair and fiber connections must be established before the link LEDs will light.
To test a media converter by itself, have an appropriate fiber patch cable, and then
follow the three easy steps to test:
