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 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 Port can operate in full duplex mode with an average data rate of 10 Gbps
