FDX/Col LED
The FDX/Col (full duplex/collision) LED indicates when a port is in full
duplex (FDX) mode, or when two or more stations on the specific net-
work segment attempt to transmit packets simultaneously, causing a
packet collision.
∆
Note: This LED can display both green and yellow
colors (see Table 3-1).
∆
Note: Collisions are normal in Fast Ethernet networks.
Excessive collisions may indicate that your network is
congested.
Table 3-1 describes the possible status indications of the FDX/Col
LEDs.
