Note
Both native Fast Ethernet/Ethernet ports and Gigabit Ethernet ports are reported as GE0/0 and GE0/1 in software. You
must use the media-type command to select which media type you want to use before you configure these ports. See
“Configure the Native Gigabit Ethernet and Fast Ethernet/Ethernet Interfaces” section on page 28.
GBIC Cabling and Connection Equipment
The Gigabit Interface Converter (GBIC) port is a 1000-Mbps optical interface in the form of an SC-type duplex port that
supports IEEE 802.3z interfaces compliant with the 1000BASEX standard. Gigabit Interface Converter models WS-G5486 or
GBIC-SX=, WS-G5484 or GBIC-LX/LH=, and WS-G5487 or GBIC-ZX-SM= are supported in the Cisco 7401ASR router. For
cabling distances, specifications, and other information, see the online Cisco 7401ASR Router Installation and Configuration
Guide at
http://www.cisco.com/univercd/cc/td/doc/product/core/7401/7401icg/index.htm.
Note
All Gigabit Ethernet GBIC ports have SC-type connectors.
Warning

ecause invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected, avoid
exposure to laser radiation and do not stare into open apertures.

Note
There is no support for copper-based GBICs (1000BASET) as these do not conform to the GBIC standard and have not
been validated by Cisco.
