1 The management 0/0 interface is a Fast Ethernet interface designed for management traffic only. 2 Not supported at this time. 3 GigabitEthernet interfaces, from right to left, GigabitEthernet 0/0, GigabitEthernet 0/1, GigabitEthernet 0/2, and GigabitEthernet 0/3.

For more information about the Management port, see themanagement only command in the Cisco Security Appliance Command Reference.

The Cisco ASA 5550 has a fixed configuration with an embedded 4GE slot as shown in Figure 1-3.

Note The Cisco ASA 5510 adaptive security appliance supports only 10/100BaseTX. The Cisco ASA 5520 and the Cisco ASA 5540 support 1000BaseT.

Memory Requirements

Table 1-3 lists the CPU and the memory specifications for each model.

Table 1-3 CPU and Memory Specifications

ASA Model	CPU	Default DRAM Memory	Default Internal Flash Memory
Cisco ASA 5510	1.6 GHz Celeron	256 MB	512MB
Cisco ASA 5520	2.0 GHz Celeron	512 MB	512MB
Cisco ASA 5540	2.0 GHz Pentium 4	1024 MB	512MB
Cisco ASA 5550	3.0 GHz Pentium 4	4096 MB	512MB

In a failover configuration, the two units must have the same hardware configuration. They must be the same model, have the same number and types of interfaces, and the same amount of RAM.

---

Note The two units do not have to have the same size Flash memory. If using units with different Flash memory sizes in your failover configuration, make sure the unit with the smaller Flash memory has enough space to accommodate the software image files and the configuration files. If it does not, configuration synchronization from the unit with the larger Flash memory to the unit with the smaller Flash memory will fail.
