Copper and Optical GE MIC and Native Ports
The copper GE (labeled “ENET 1 Gb”) MIC provides two 1000Base-T ports with RJ-45 connectors; the
optical GE (also labeled “ENET 1 Gb”) MIC provides two 1000Base-FX ports; each port supports an SFP
transceiver. Transceiver types are described in
Transceivers for SmartEdge 100 Optical Ports . Figure 2-2
shows the front panels of these MICs.
Figure 2-2 Copper and Optical GE MICs
Any combination of the following types of SFP optical transceivers are supported on any port on the optical
GE MIC:
• 1000Base-SX—Short range
• 1000Base-LX—Long range
The copper GE MIC uses RJ-45 connectors instead of copper-based SFP transceivers.
Table 2-2 lists the GE MIC and native port specifications for the various types of GE ports. In Table 2-2,
MMF and SMF refer to multimode fiber and single-mode fiber, respectively.
Caution
Risk of data loss. You can corrupt the system if you attempt to install SFP transceivers that are
not purchased from Redback, because these items have not been tested with the SmartEdge
router. To reduce the risk, install only the transceivers purchased from Redback.
