ASA 5500-X I/O Cards

ASA 5500-X I/O Cards

The Cisco ASA 5500-X Series 6-port Gigabit Ethernet interface cards extend the I/O capabilities of the ASA 5525-X, ASA 5545-X, and ASA 5555-X models by providing additional Gigabit Ethernet ports.

The I/O cards provide the following benefits:

•Segmentation of network traffic into separate security zones

•Fiber optic cable connectivity for communicating over long distances

•Load sharing of traffic and protection against link failure by using EtherChannel

•Support for Jumbo Ethernet frames of up to 9000 bytes

•Protection for Active/Active failover and of full-mesh firewall deployments against cable failure

For More Information

For information about installing an I/O card in your ASA, see Chapter 4, “Maintenance and Upgrade Procedures for the ASA 5500-X.”

SFP Modules

The ASA uses a field-replaceable SFP module to establish Gigabit Ethernet connections. Table 1-1lists the supported SFP modules.

Table 1-1	Supported SFP Modules
SFP Module		Type of Connection	Cisco Part Number
1000BASE-LX/LH		Fiber-optic	GLC-LH-SM=
1000BASE-SX		Fiber-optic	GLC-SX-MM=

The 1000BASE-LX/LH and 1000BASE-SX SFP modules are used to establish fiber-optic connections. Use fiber-optic cables with LC connectors to connect to an SFP module. The SFP modules support 850 to 1550 nm nominal wavelengths. The cables must not exceed the required cable length for reliable communications. Table 1-2lists the cable length requirements.

Table 1-2	Cabling Requirements for Fiber-Optic SFP Modules
	62.5/125 micron	50/125 micron	62.5/125 micron	50/125 micron	9/125 micron
SFP	Multimode 850	Multimode 850	Multimode 1310	Multimode 1310	Single-mode
Module	nm Fiber	nm Fiber	nm Fiber	nm Fiber	1310 nm Fiber

			500 Mhz-km	400 Mhz-km
SX	275 m at	550 m at	—	—	—
	200 Mhz-km	500 Mhz-km

Use only Cisco certified SFP modules on the ASA. Each SFP module has an internal serial EEPROM that is encoded with security information. This encoding provides a way for Cisco to identify and validate that the SFP module meets the requirements for the ASA.
