I just replaced the WS-X6248-RJ-45 with WS-X6148-RJ-45 within the same slot for Catalyst 6509 Switch . However , I can't config the FE port in WS-X6248-RJ-45 into switchport as below indicated :
(config-if)# no ip address
(config-if)# switchport mode access
Command rejected: Fa7/4 not a switching port.
While I put the WS-X6148-RJ-45 back to the same slot , the same error message appear , that mean I can't place the port for this subject slot (No matter with WS-X6148-RJ-45 or WS-X6248-RJ-45)
back to "switchport" any more .
I am wondering if the OIR for this two module make it happen and if I have to reboot the system to make it come back to normal condition as the default setting for the ports of these two module was supposed to be "switchport" !!
