GE-8 IOA

IOA label	ES2–S1 GE-8 IOA
Number of IOA ports	8
Software release	First supported: 7.2.0
Description	21 W Gigabit Ethernet Half-height module See Slot Combinations for more information on combining IOAs in a slot. Uses a range of small form-factor pluggable (SFP) transceivers to support different modes and cable lengths Uses either optical or copper SFPs. The optical transceivers are 1000Base-SX, 1000Base-LX, and 1000Base-ZX compliant. The copper transceivers are 1000Base-T compliant.
Capability	Ethernet (IEEE 802.3z) 1000Base-SX/LX/ZX
Software features	See Ethernet IOAs for information about the layer 2 and layer 3 protocols and applications that this module combination supports.
Line module compatibility	ES2 4G LM
SRP module compatibility	SRP-100 SRP-320
Line module redundancy compatibility	Can be paired with an ES2 4G LM. Must be installed in the same redundancy group as an ES2 4G LM and ES2–S1 REDUND IOA combination.
Port redundancy support	Not applicable
Cables and connectors (copper SFP)	Maximum range is 100 meters on CAT5 cable.
Cables and connectors (multimode [SX])	One LC full duplex connector Transmit power: min: –9.5 dBm max: —4 dBm Receive input power: min: –20 dBm max: 0 dBm See the following corresponding table (SX Fiber Optic Cabling) for cabling requirements. See E320 Hardware Guide, Chapter 5, Cabling the Router for more information.
Cables and connectors (single-mode [LX])	One LC full duplex connector Transmit power: min: –9.5 dBm max: –3 dBm Receive input power: min: –20 dBm max: –3 dBm See the following corresponding table (LX Fiber Optic Cabling) for cabling requirements. See E320 Hardware Guide, Chapter 5, Cabling the Router for more information.
Cables and connectors (single-mode [ZX])	One LC full duplex connector Transmit power: min: –2 dBm max: 3dBm Receive input power: min: –22 dBm max: –3 dBm See the following corresponding table (ZX Fiber Optic Cabling) for cabling requirements. See E320 Hardware Guide, Chapter 5, Cabling the Router for more information.
LEDs	Board-level LEDs: OK (green)—IOA is online and is functioning properly FAIL (red)—Failure detected Port LEDs: LK (green)—Ethernet link is up ACT (green)—Blinks when Ethernet traffic is being received
Alarms, errors, and events	See Monitoring Ethernet Interfaces in JUNOSe Physical Layer Configuration Guide, Chapter 6, Configuring Ethernet Interfaces.
