Introducing the Switch Introducing the Switch Front of the Switch ■ If the Link (LnK) indicator LED is lit, each port LED displays link information for the associated port. If the port LED is in Link mode and it is blinking, the port has failed its self test. The Fault and Test LEDs will be blinking simultaneously. ■ If the Activity (Act) indicator LED is lit, each port LED displays activity information for the associated port-it flickers as network traffic is received and transmitted through the port. ■ If the Full Duplex (FDx) indicator LED is lit, the port LEDs light for those ports that are operating in full duplex. ■ If the Speed (Spd) indicator LED is lit, the port LEDs behave as follows to indicate the connection speed for the port: • Off = 10 Mbps • Flashing = 100 Mbps (the flashing behavior is a repeated on/off cycle once every 0.5 sec.) • On = 1000 Mbps Reset Button This button is used to reset the switch while it is powered on. This action clears any temporary error conditions that may have occurred and executes the switch self test. Clear Button This button is used for these purposes: ■ Deleting Passwords - When pressed by itself for at least one second, the button deletes any switch console access passwords that you may have configured. Use this feature if you have misplaced the password and need console access. This button is provided for your convenience, but its presence means that if you are concerned with the security of the switch configuration and operation, you should make sure the switch is installed in a secure location, such as a locked wiring closet. ■ Restoring Factory Default Configuration - When pressed with the Reset button in a specific pattern, any configuration changes you may have made through the switch console, the web browser interface, and SNMP management are removed, and the factory default configuration is restored to the switch.

■
If the Link (LnK) indicator LED is lit, each port LED displays link infor-
mation for the associated port.
If the port LED is in Link mode and it is blinking, the port has failed its
self test. The Fault and Test LEDs will be blinking simultaneously.
■
If the Activity (Act) indicator LED is lit, each port LED displays activity
information for the associated port—it flickers as network traffic is
received and transmitted through the port.
■
If the Full Duplex (FDx) indicator LED is lit, the port LEDs light for those
ports that are operating in full duplex.
■
If the Speed (Spd) indicator LED is lit, the port LEDs behave as follows
to indicate the connection speed for the port:
•
Off = 10 Mbps
•
Flashing = 100 Mbps (the flashing behavior is a repeated on/off cycle
once every 0.5 sec.)
•
On = 1000 Mbps
