yes you removed Vland 2 but still the vlan remains there in the dir of the Cisco Switch

type Dir and then check...

so you can add this ports to another Vlan and you'll see them.

or else remove vlan from the directory...

Those ports were in a vlan which got deleted.  What you can do is:

Switch(config)#interface fa4/0/1
Switch (config)#switchport access vlan 1

or any other vlan as per requirement.

Do you need port securitu on fa4/0/1....just to troubleshoot will you be able to remove using:

Switch(config)#intetface fa4/0/1
Switch(config-if)#no switchport port-security

Light does not glow because for some reason security violation has occured and port has been shutdown...to renable you have to enter

Switch(config)#interface fa4/0/1
Switch (config-if)shutdown
Switch (config-if)no shutdown

If still things are not working out for you. Is it ok for you to do a total reset of the switch? If yes then do the following:

Switch#erase startup-config
Erasing the nvram filesystem will remove all files! Continue? [confirm]y[OK]
Erase of nvram: complete
Switch#
Switch# reload


System configuration has been modified. Save? [yes/no]: n    

!--- Do not save the configuration at this prompt. Otherwise, the switch !--- reloads with the current running configuration and does not reset to default.
Proceed with reload? [confirm]y    


After switch reloads you have to remove all vlan data using the following steps:


Switch# delete flash:vlan.dat
Delete filename [vlan.dat]?

!--- Press Enter.

Delete flash:vlan.dat? [confirm]y

Switch# reload
Proceed with reload? [confirm]y
4w5d: %SYS-5-RELOAD: Reload requested


After reload all should be good if there are no hardware issues.
