Cisco ASA 5520 Model

Cisco ASA 5520 provides security services for medium-sized enterprises. The Cisco ASA 5520 and 5540 models are similar to the Cisco ASA 5510 model. They are all 1RUs, and the chassis external layouts are similar with the exception of the interfaces. The Cisco ASA 5520 and ASA 5540 models have four Gigabit Ethernet (10/100/1000) copper-based RJ-45 ports instead of the four Fast Ethernet ports in the Cisco ASA 5510 model. They also include a Fast Ethernet port for OOB management. Virtualization (security contexts) is supported in the Cisco ASA 5520 and 5540 models.

Figure 3-3 illustrates the front view of the Cisco ASA 5520 model.

The back view of ASA 5520 is identical to that of ASA 5510, except that the Cisco ASA 5520 has four Gigabit Ethernet (10/100/1000) ports whereas the Cisco ASA 5510 has four Fast Ethernet ports.

With the installation of a VPN Plus upgrade license, Cisco ASA 5520 can terminate up to 750 IPSec or WebVPN tunnels.
