• 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.

configuration

program via a serial

port connection

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.

connection to the switch’s console port and power cycle

the switch. Immediately after powering on, press
