The E120 router and the E320 router support the ES2-S2 10GE PR IOA. Other E-series routers do not support the ES2-S2 10GE PR IOA.
The ES2-S2 10GE PR 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-S2 10GE PR IOA has one port, uses a range of XFPs to support different optical modes and cabling distances, and accepts 10 LC-style fiber-optic connectors.
The single port on the ES2-S2 10GE PR IOA has a redundant port. If the active port fails, the redundant port automatically becomes active. You can configure only the active port for a 10-Gigabit Ethernet interface; you cannot configure the redundant port. Cabling both ports provides a redundant path to the 10-Gigabit Ethernet interface.
The ES2-S2 10GE PR IOA pairs with the ES2 10G Uplink LM to provide uplink services or the ES2 10G LM to provide access services.
