Thats wierd. I would have understood if the prompt looked like this "AV_Switch_1>". That would have indicated that you were at the operator prompt.
Do a "?" at the prompt to list the available commands. It should look like this:
AV_Switch_1# ?
backup Backup next startup-configuration file to TFTP server
boot Reboot the device.
clear Clear information.
clock Configure or show the current time, date, and local time offset.
command-alias Specify a command alias
configure Enter the Configuration context.
copy Copy datafiles to or from the switch.
debug Enable/disable debug logging.
delete Delete a file
<truncated>
verify Verify the signature of a switch firmware image.
AV_Switch_1#
If that isn't the case and it looks more like this:
AV_Switch_1> ?
chassislocate Control the chassis locate LED.
dir Display a list of the files and subdirectories
in a directory on a USB device.
display Display current system information.
enable Enter the Manager command context.
exit Return to the previous context or terminate current
console/telnet session if you are in the Operator
context level.
link-test Test the connection to a MAC address on the LAN.
logout Terminate this console or telnet session.
menu Enter the menu-based console user interface.
page Toggle paging mode.
ping Send IPv4 ping request(s) to a device on the network.
ping6 Send IPv6 ping request(s) to a device on the network.
quit Exit the current command view
show Display switch operation information.
traceroute Trace the IPv4 route to a device on the network.
traceroute6 Trace the IPv6 route to a device on the network.
verify Verify the signature of a switch firmware image.
AV_Switch_1>
Then you have to use the "enable" command first to get to the manager prompt.
