Note Odd-numbered pins always connect to a white wire with a colored stripe.
1.12.2.2 Replace Faulty GBIC, SFP, or XFP Connectors
GBICs and Small Form-factor Pluggables (SFP or XFP) are hot-swappable and can be installed or
removed while the card or shelf assembly is powered and running.

Statement 272
GBICs and SFPs/XFPs 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, refer to the Cisco ONS 15454 Reference Manual.
Note GBICs and SFPs must be matched on either end by type: SX to SX, LX to LX, or ZX to ZX.
Note All versions of G1K-4 cards support coarse wavelength division multiplexing (CWDM) GBICs.
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 Figure 1-55.
