Troubleshooting Chart

Symptom Action

Cannot connect using

Telnet, Web browser, or

SNMP software

• Be sure you have configured the agent with a valid IP address, subnet

mask and default gateway.

• Check that you have a valid network connection to the switch and that

the port you are using has not been disabled.

• Check network cabling between the management station and the

switch.

• If you cannot connect using Telnet, there may already be another active

session. Try connecting again at a later time.

Cannot access the

on-board configuration

program via a serial port

connection

• Be sure you have set the terminal emulator program to VT100

compatible, 8 data bits, 1 stop bit, no parity, and 9600 bps.

• Check that the null-modem serial cable conforms to the pin-out

connections provided in Appendix B.
