SFP Unpacking

Support Postcard. Notify your sales representative immediately if any of the above items is missing or damaged.
Save the packaging for possible future use.
SFP Installation
Cautions
•
The SFP module is keyed to only be installed one way. If forced the wrong way, damage may occur.
•
Avoid getting dust or other contaminants into the fiber bore of the SFP transceiver module, as this will cause
the optics to not operate properly.
•
Clean the optic surfaces of the optical fiber before you plug them back in to the optical bores of another SFP
module. See Fiber Optic Association
Cleaning Fiber Optic Connections
•
Each port must match the wavelength specifications on the other end of the cable, and the cable must not
exceed the specified cable length for reliable communications.
Installing an SFP Module
1.
Review the Cautions above.
2.
Attach an ESD-preventive wrist strap to your wrist and to an ESD ground connector or bare metal surface on
the chassis.
3.
Remove the SFP transceiver module from its protective packaging. Note: Do not remove the optical bore
dust plugs until directed to do so in a later procedure.
4.
Check the slot orientation;
for some devices (e.g., S4224) some slots are “upside down” compared to other
slots.
5.
Position the SFP device at the desired installation slot, with the label facing correctly.
