# 10GE PR IOA

> IOA label | ES2-S2 10GE PR IOA
> Number of IOA ports | 2 1 active, 1 redundant
> Software release | First supported: 7.2.0
> Description | 40 W Full-height module Uses a range of 10-gigabit small form-factor pluggable (XFP) transceivers to support different modes and cable lengths. Pairs only with ES2 10G UPLINK LM and ES2 10G LM to provide 10-Gigabit Ethernet operation through a single line interface In a 100 Gbps configuration, the router can accommodate up to two ES2 10G UPLINK LM and ES2-S2 10GE PR IOA combinations In a 100 Gbps configuration, the router can accommodate up to two ES2 10G LM and ES2-S2 10GE PR IOA combinations In a 320 Gbps configuration, the router can accommodate up to twelve ES2 10G LM and ES2-S2 10GE PR IOA combinations
> Capability | Ethernet (IEEE 802.3ae) 10Gb Base-SR/LR/ER/ZR Port can operate in full duplex mode with an average data rate of 10 Gbps
> Software features | See Ethernet IOAs for information about the layer 2 and layer 3 protocols and applications that this module combination supports.
