Warning
Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector.
Warning
Do not stare into the beam directly with optical instruments. Viewing the laser output with certain
optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of
100 mm could pose an eye hazard. Statement 1056
G-Series cards manufactured before August 2003 do not support DWDM GBICs. G1K-4 cards
Note
compatible with DWDM GBICs have a Common Language Equipment Identification (CLEI) code of
WM5IRWPCAA.
All versions of G1K-4 cards support coarse wavelength division multiplexing (CWDM) GBICs.
Note
GBICs, SFPs, and XFPs are hot-swappable and can therefore be installed/removed while the card/shelf
Note
assembly is powered and running.
Remove the GBIC, SFP, or XFP from its protective packaging.
Step 1
Check the label to verify that the GBIC, SFP, or XFP is the correct type for your network. For a list of
Step 2
GBICs and SFPs that are compatible with Ethernet cards, refer to the "Ethernet Cards" chapter in the
