MPA.)

Install and Remove Transceiver Modules

Before you remove or install an SFP or SFP+ module, read the installation information in this section.

Warning

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or

view directly with optical instruments. Statement 1051

Caution

Protect the line card by inserting a clean SFP/SFP+ module cage cover, shown in the figure below, into the

optical module cage when there is no SFP or SFP+ module installed.

Caution

Protect the SFP or SFP+ modules by inserting clean dust covers into them after the cables are removed. Be

sure to clean the optic surfaces of the fiber cables before you plug them back into the optical ports of another

module. Avoid getting dust and other contaminants into the optical ports of your SFP or SFP+ modules,

because the optics do not work correctly when obstructed by dust.
