Problem 5: Network performance between a twisted pair port on the
switch and a network device is slow.
Solution: There might be a duplex mode mismatch between the port and
the network device. This occurs when a twisted pair port using Auto-
Negotiation is connected to a device with a fixed duplex mode of full
duplex. If this is the cause of the problem, adjust the duplex mode of the
port on the network device or switch so that both ports are using the same
duplex mode.
Problem 6: The switch functions intermittently.
Solutions: Check the system hardware status through the management
software:
Use the SHOW SYSTEM ENVIRONMENT command in the
Privileged Exec mode to verify that the input voltage from the
power source to the switch is stable and within the approved
operating range. The unit will shutdown if the input voltage
fluctuates above or below the approved operating range.
For switches that have a ventilation fan, use the SHOW SYSTEM
ENVIRONMENT command in the Privileged Exec mode to verify
that it is operating correctly.
Verify that the location of the switch provides adequate airflow. The
unit will shutdown if it is in danger of overheating.
