The Gigabit Ethernet module is an 802.3z standards-based interface module, which provides a high bandwidth yet cost-effective uplink solution for the Cisco 10000 ESR. The Gigabit Ethernet module occupies a full interface slot in the Cisco 10000 ESR (with no slot dependency), is hot swappable, and multiple modules can be configured in the chassis to support network layer redundancy or different destinations. The module supports a single gigabit Ethernet interface based on GBIC technology enabling the user to select between a variety of gigabit Ethernet interface types.
