In ASA 5550 fiber interfaces are not detecting after connecting the SFP module. It has "maximum physical interfaces=unlimited". As per the show tech only 8 physcial interfaces are showing, 4 ports copper in slot 0 and 4 ports copper in slot 1. We have tried in all the methods by changing media type also, also checked in another similar kind of ASA model and found the same status.
Please let us know is there any extra command to intialize the module only to enable fibre interfaces.
The ASA 5550 only has 8 physical ports (gigabit ports) plus a management port.
the 4GE-SSM allows you to use 4 ports and not 8. You can configure the 4GE-SSM to use RJ-45 or SFP but only 4 ports will be active.
The interface name will not change if you use SFP compared to RJ-45 since there are only 4 active ports available on the 4GE-SSM of the ASA5550.

Thanks for your response. We have connected SFP module (GLC-SX-MM) to gi 1/0 in the fibre slot and changed the media type to sfp. Connected the fibre cable to the interface from the swtich to ASA, but no luck. At the switch interface status showing as "amber".
