Gigabit Ethernet I/O Modules and IOAs
Gigabit Ethernet interfaces are supported on the following modules:
• GE I/O module
•
GE-2 SFP I/O module
•
GE-8 I/O module
• OC3-2 GE APS I/O module
• ES2-S1 GE-4 IOA
•
ES2-S1 GE-8 IOA
•
ES2-S3 GE-20 IOA
GE I/O Module
ERX7xx models, ERX14xx models, and the ERX310 router all support the GE I/O module.
You can pair any of the following types of GE I/O modules with the GE/FE line module:
•
The GE I/O SFP module uses a range of SFPs to support different optical modes and
cabling distances. The I/O module accepts up to two pairs (Tx/Rx) of LC-style
fiber-optic connectors that support different optical modes and cabling distances.
Alternatively, the I/O module supports up to two pairs of copper SFPs.
•
The GE I/O MULTI MODE module accepts up to two pairs (Tx/Rx) of SC-style fiber-optic
connectors.
• The GE I/O SINGLE MODE module accepts up to two pairs (Tx/Rx) of SC-style
fiber-optic connectors.
The GE I/O module has two ports: one port (port 0) is active (also known as primary ),
and the other port (port 0R) is redundant. If the active port fails, the redundant port
automatically becomes active.
You can configure only port 0 for a Gigabit Ethernet interface; you cannot configure
redundant port 0R. Cabling both ports provides a redundant path to the Gigabit Ethernet
interface.
GE-2 SFP I/O Module
The ERX1440 router and the ERX310 routers both support the GE-2 SFP I/O module.
Other E Series routers do not support the GE-2 SFP I/O module. The GE-2 SFP I/O module
was previously called the 2XGE APS I/O module.
The GE-2 SFP I/O module pairs with the GE-2 line module and the GE-HDE line module.
You can install the GE-2 line module or the GE-HDE line module and its corresponding
GE-2 SFP I/O module in slot 1 or slot 2 of an ERX310 router or in any slot of an ERX1440
router.
