I have a Cisco ASA 5520 that I'd like to be able to connect directly to our gigabit fiber connection (we're currently connected through a media converter that's causing problems). I've found the following:
Cisco ASA 5500 Series 4 Port Gigabit Ethernet Security Services Module
For the 5520 (and 5510, 5540) there is no other module available that would fit.
For a customer with the same problem we decided to use an SG300-10P 10-Port-Switch from the Small-Business-Line. That worked fine and safed a lot of bucks. We decided to use the PoE-version as the power-connector on that device is more reliable than the one on the non PoE-version.
