Cisco ASA 5500-X Series 6-port Gigabit Ethernet Interface Cards extend the I/O profile of the ASA 5525-X through ASA 5555-X by providing additional GE ports. The cards provide the following benefits:

• Better segmentation of network traffic (into separate security zones)
• Fiber optic cable connectivity for long distance communication
• Load sharing of traffic as well as protection against link failure by using EtherChannel
• Support for Jumbo Ethernet frames of up to 9000 bytes
• Protects the most demanding Active/Active and full mesh firewall deployments against cable failure
