GBIC Features

Warning

Because invisible laser radiation may be emitted from the aperture of the port

when no cable is connected, avoid exposure to laser radiation and do not stare

into open apertures.

Statement 70

GBICs (see Figure 4-1) are hot-swappable input/output devices that plug into a

Gigabit Ethernet switching module, linking the module with a fiber-optic

network. The GBICs use SC-type connectors and plug into connectors on the

module. You can install any combination of GBICs in the Gigabit Ethernet

switching module.
