With the implementation of a half-height line card, the Cisco 10000 Series doubles its modularity as well as its density for LAN interfaces. Doubling its Gigabit Ethernet density enables customers to insert dual Gigabit Ethernet uplinks without taking up an additional line card slot.The Cisco 10000 Series Gigabit Ethernet Half-Height Module supports modular small form-factor pluggable (SFP) transceivers to ensure that customers have maximum flexibility in configuring physical network interfaces. The 1000BASE-SX and 1000BASE-LX SFP transceivers available in these modules are hot swappable, providing a quick and easy method of changing physical interfaces.The Cisco 10000 Series Gigabit Ethernet Half-Height Module is based on the IEEE 802.3z industry standard - ensuring interoperability and compatibility with other standards-based Gigabit Ethernet products in the customer's network. Gigabit Ethernet standards compliance along with Cisco manageability and standard Cisco IOS Software ensures high-speed interoperability with existing Gigabit Ethernet products in the Cisco 12000 Series and Cisco Catalyst switches.
