MIC and Native Port Descriptions
This chapter describes the SmartEdge
®
100 native ports and each of the Fast Ethernet (FE) and Gigabit
Ethernet (GE) media interface cards (MICs) that are currently available for the SmartEdge 100 router.
MIC types include:
• Copper and Optical FE MICs
• Copper and Optical GE MIC and Native Ports
Copper and Optical FE MICs
The copper FE MIC (labeled “ENET 10/100”) provides 12 10Base-T or 100Base-TX ports with RJ-45
connectors; the optical FE MIC (labeled “ENET FX-100”) provides 12 100Base-FX ports; each optical port
supports a small form-factor pluggable (SFP) transceiver. Transceiver types for the optical FE MIC are
described in the
Transceivers for SmartEdge 100 Optical Ports document. The speed for each copper FE
port is selectable as 10 Mbps or 100 Mbps. Figure 2-1 shows the front panels of these MICs.
Any combination of the following types of SFP optical transceivers are supported on any port on the optical
FE MIC:
• 100Base-FX—Short range
• 100Base-LX10—Long range
The copper FE MIC uses RJ-45 connectors instead of copper-based SFP transceivers.
Note The term, GE, applies to any GE native port or MIC that supports a port speed of 1 Gbps or greater;
unless explicitly stated, the speed of any GE port is 1 Gbps.
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.
