Cisco ASA 5510 Model

The Cisco ASA 5510 model is designed to deliver advanced security services for small and medium-sized businesses and enterprise branch offices. This model provides advanced firewall and VPN capabilities and has optional Anti-X (Adaptive Threat Defense) and IPS services that use the Cisco AIP-SSM-10 module.

Figure 3-1 shows a front view of the Cisco ASA 5510 model.

Figure 3-1. Cisco ASA 5510 Front View

The front panel has the following five LEDs:

  1. Power Solid green indicates that the appliance is powered on.
  2. Status Flashing green indicates that the system is booting and power-up tests are running. Solid green indicates that the system tests passed and the system is operational. Amber solid indicates that the system tests failed.
  3. Active Flashing green indicates network activity.
  4. VPN Solid green indicates that one or more VPN tunnels are active.
  5. Flash Solid green indicates that the Flash memory card is being accessed.

The three ASA models, 5510, 5520, and 5540, offer a one-rack unit (1RU) design. They also have an expansion slot for security-services modules. Figure 3-2 shows a back view of the Cisco ASA 5510 model.

Figure 3-2. Cisco ASA 5510 Back View

The Power, Status, Active, VPN, and Flash LEDs are also present on the back of the Cisco ASA 5510. The Cisco ASA 5510 includes five integrated 10/100 Fast Ethernet network interfaces. Three of these five Fast Ethernet ports are enabled by default (0 to 2). The fifth interface is reserved for out-of-band (OOB) management. The Security Plus license allows you to enable the fourth Fast Ethernet port, and the restriction on the OOB port is also removed. Therefore, you can use all five Fast Ethernet interfaces for the through traffic and apply security services.


The OOB Ethernet port restriction is removed with the Security Plus license; however, it is highly recommended that you solely use this port for OOB management.

Each Fast Ethernet port has an activity LED and a link LED:

  • The activity LED shows that data is passing on the network to which the port is attached.
  • The link LED shows that the correct cable is in use and the port is operational.

The Cisco ASA 5510 Security Plus license enables Cisco ASA 5510 to provide VLAN support on switched networks (up to 10 VLANs). The Security Plus upgrade license also provides a greater number of concurrent virtual private network (VPN) connections for remote users and site-to-site connections.


Similar to the Cisco PIX firewalls, Cisco ASA requires a unique license key to enable certain features. This license key is a 40-digit hexadecimal number represented in 5 tuples (set of fixed-length data types). The security appliance allows an administrator to enter the license key by using the activation-key command.

The output of the show version command includes information about the license installed on the Cisco ASA. The following is an example of the output:

The highlighted lines show the license (features) enabled on the Cisco ASA version.

The RJ-45 console port allows you to physically connect to the appliance to access its command-line interface (CLI) for initial configuration. The AUX (auxiliary) port allows you to connect an external modem for OOB management. The Flash card slot allows you to use an external Flash card to save system images and configuration files.

Two USB ports in the back of all Cisco ASA models are designed for future features. The Reset button is a multifunction switch. It provides the following functionality:

  • If pressed longer than 1 second and less than 5 seconds, the system initiates a hardware reset. The saved configuration will be loaded at boot time.
  • If pressed longer than 5 seconds, the system clears the configuration and loads the default configuration.
