modules when no cable is connected. Avoid exposure and do not stare into open apertures.
GBICs and SFPs are input/output devices that plug into a Gigabit Ethernet card to link the port with the
fiber-optic network. The type of GBIC or SFP determines the maximum distance that the Ethernet traffic
can travel from the card to the next network device. For a description of GBICs and SFPs and their
capabilities, see
Guide.
Note GBICs and SFPs must be matched on either end by type: SX to SX, LX to LX, or ZX to ZX.
Note DWDM and coarse wavelength division multiplexing (CWDM) GBICs do not function with Software
R4.6.
GBICs are available in two different models. One GBIC model has two clips (one on each side of the
GBIC) that secure the GBIC in the slot on the E1000-2-G, G-Series, or G1K-4 card. The other model
has a locking handle. Both models are shown in
