Symptom

Action

Cannot connect using

Telnet, Web browser,

or SNMP software

• Be sure to have configured the agent with a valid IP

address, subnet mask and default gateway.

• Be sure that your management station has management

VLAN access to the switch (default is VLAN 1).

• 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, you may have exceeded

the maximum number of concurrent Telnet sessions
permitted. Try connecting again at a later time.

Cannot access

the on-board

configuration

program via a serial

port connection

• Be sure to 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.

Forgot or lost the

password

• Set the switch to its default configuration. Make a direct

connection to the switch’s console port and power cycle
the switch. Immediately after powering on, press
<Ctrl><u> to access the system file menu. Select <D> to
delete all user-defined configuration files. Press <Q> to
boot the switch.
