Enable SSH on Dell Power connect 2848

I have a dell power connect 2848 and I am looking to enable ssh on it.   I have tried following the below instructions but they all error out for me except the config command but i can still make no changes.  I am logging onto the switch as admin.   I am connecting to the switch via telnet.  Any ideas what i am doing wrong?  thanks

1. Connect to the switch via CLI
2. To enable SSH, enter the following commands:
   1. console>enable
   2. console#config
   3. console(config)#crypto key generate rsa
   4. console(config)#crypto key generate dsa
   5. console(config)#ip ssh server
3. To disable telnet, enter: console(config)#no ip telnet server
4. To enable HTTPS, enter the following commands"
   1. console(config)# console(config)#crypto certificate 1 generate key
   2. console(config)#ip https certificate 1
   3. console(config)# ip http secure-server
