Chapter 4      Troubleshooting
Clearing the Switch IP Address and Configuration
These circumstances can result in a mismatch:
A manually set speed or duplex parameter is different from the manually set speed or duplex 
parameter on the connected port.
A port is set to autonegotiate, and the connected port is set to full duplex with no autonegotiation.
To maximize switch performance and to ensure a link, follow one of these guidelines when you set or 
change the settings for duplex and speed:
Let both ports autonegotiate both speed and duplex.
Manually set the speed and duplex parameters for the ports on both ends of the connection.
If a remote device does not autonegotiate, configure the duplex settings on the two ports to match. 
The speed parameter can adjust itself even if the connected port does not autonegotiate.
Autonegotiation and Network Interface Cards
Problems sometimes occur between the switch and third-party network interface cards (NICs). By 
default, the switch ports and interfaces are set to autonegotiate. It is common for devices such as laptop 
computers or other devices to also be set to autonegotiate, yet sometimes autonegotiation issues occur.
To troubleshoot autonegotiation problems, try to manually set both sides of the connection. If this does 
not solve the problem, the firmware or software on your NIC card might be causing the problem. 
Upgrade the NIC card driver to the latest version available from the manufacturer.
Cabling Distance
If the port statistics show excessive FCS, late-collision, or alignment errors, verify that the cable 
distance from the switch to the connected device meets the recommended guidelines. See Appendix B, 
“Connector and Cable Specifications,” for cabling guidelines.
Clearing the Switch IP Address and Configuration
If you have configured a new switch with an incorrect IP address, you can clear the IP address that is 
configured on the switch.
CautionThis procedure clears the IP address and all configuration information that is stored on the switch. Do 
not follow this procedure unless you want to completely reconfigure the switch.
Follow these steps to return your switch to the factory default settings:
1.Press and hold the Mode button.
The switch LEDs begin blinking after about 2 seconds. If the switch is not configured, the LEDs 
above the Mode button turn green. You can omit this step and run Express Setup to configure the 
switch.
2.Continue holding down the Mode button. The LEDs stop blinking after an additional 8 seconds, and 
then the switch reboots.

Chapter 4      Troubleshooting
Locating the Switch Serial Number
The switch now behaves like an unconfigured switch. You can configure the switch by using Express 
Setup as described in the switch getting started guide that is included with the switch.
You can also configure the switch by using the CLI setup procedure described in Appendix D, 
“Configuring the Switch with the CLI-Based Setup Program.” 
Locating the Switch Serial Number
If you contact Cisco Technical Assistance, you need to know the serial number of your switch. See 
Figure 4-1 through Figure 4-5 to locate the serial number on your switch. You can also use the show 
version command to get the serial number.
