Cisco Cisco Catalyst 4506-E Switch Installation Guide

Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into 
beams or view directly with optical instruments. Statement 1051

Make sure that the optical connectors are clean before making the connections. Contaminated connectors 
can damage the fiber and cause data errors. 

Always insert the network connector completely into the socket. A secure connection is especially 
important when you are establishing a connection between a module and a long distance (1.24 miles) 
(2 km) network or a module and a suspected highly attenuated network. If the link LED does not light, 
try removing the network cable plug and reinserting it firmly into the module socket. It is possible that 
dirt or skin oils have accumulated on the plug faceplate (around the optical-fiber openings), generating 
significant attenuation and reducing the optical power levels below threshold levels so that a link cannot 
be made. 

Use extreme care when removing or installing connectors so that you do not damage the connector 
housing or scratch the end-face surface of the fiber. Always install protective covers on unused or 
disconnected components to prevent contamination. Always clean fiber connectors before installing 
them.

Cisco SFP and SFP+ Transceiver Module Installation Notes

.

Use only Cisco SFP modules on your Cisco device. Each SFP module has an internal serial EEPROM 
that is encoded with security information. This encoding provides a way for Cisco to identify and 
validate that the SFP module meets the requirements for the device. 

For supported SFP transceiver media types, refer to:

guide for your switch. Configuration guides are located at:

Fiber-optic cable connectors can be damaged by improper cleaning and connection procedures. Dirty or 
damaged fiber-optic connectors can result in communication that is not repeatable or inaccurate.
