Figure1-5 Gigabit Interface Converter—GBIC
The Gigabit Ethernet 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-5484 or GBIC-SX, WS-G5486 or GBIC -LX/LH, and
WS-G5487 or GBIC-ZX are supported in the Cisco 7401ASR router.
Note The GBIC must be installed before you connect the cables to it.
•You can install and remove GBICs with power on to the system.
•Disconnect all cables before removing or installing a GBIC. We strongly recommen d that you do
not install or remove the GBIC with optical fiber cables attached to it.
•GBICs are keyed to prevent incorrect insertion.
Warning
Because 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.
