Hardware Features
GE Ports
The GE RJ-45 copper interface ports support 10BASE-T, 100BASE-TX, and 1000BASE-T.
SFP Ports
The small-form-factor pluggable (SFP) ports support 1000BASE-LX/LH, 1000BASE-SX,
1000BASE-ZX, and Coarse Wavelength-Division Multiplexing (CWDM-8) modules, as well as 100Mbs
SFP modules.
The SFP port shares the same physical port as an RJ-45 GE port.
models that support SFP installation. The SFP port supports auto-media-detection, auto-failover and
remote fault indication (RFI), as described in the IEEE 802.3ah specification.
Use the media-type {rj45{auto-failover}} | {sfp{auto-failover}} command to enable the

router to provide specific capabilities. Services Performance Engines (SPEs), Service Modules (SMs),
and Enhanced High-Speed WAN Interface Cards (EHWICs) fit into external slots and can be removed
or replaced without opening the chassis.
Internal Services Modules (ISMs), expansion DRAM memory modules and next-generation Packet
Voice Data Modules (PVDM3s) plug into internal connectors inside the chassis. These modules can be
removed and installed only by opening the chassis on the Cisco 3900 series, or sliding the motherboard
