LED Indicators

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.

ΔNote: This LED can display both green and yellow colors (see Table 3-1).

ΔNote: 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.

Table 3-1 FDX/Collision LED status indicators

State	Status

Off	Port is in half duplex (HDX) mode
Blinking (yel-	Two or more stations on the network are

	the port, causing a collision
