The E120 router and the E320 router support the ES2-S1 10GE IOA. Other E-series routers do not support the ES2-S1 10GE IOA.
The ES2-S1 10GE IOA pairs with the ES2 4G LM to provide a 10-Gigabit Ethernet interface. For more information about the ES2 4G LM, see ES2 4G Line Module.
The ES2-S1 10GE IOA is offered in a full-height size that uses both adapter bays. The IOA is identified by the software as adapter bay 0. For more information about installing IOAs, see the E120 and E320 Hardware Guide.
The ES2-S1 10GE IOA has one port, uses a range of 10-gigabit small form-factor pluggable transceivers (XFPs) to support different optical modes and cabling distances, and accepts one LC-style fiber-optic connector.
