Installing SFP Modules
Ta b l e 3-2 Cabling Requirements for Fiber-Optic SFP Modules
Use only Cisco-certified SFP modules on the adaptive security appliance. 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 adaptive security appliance.
Note Only SFP modules certified by Cisco are supported on the adaptive security
appliance.
Caution Protect your SFP modules by inserting clean port plugs into the SFPs after the
cables are extracted from them. Be sure to clean the optic surfaces of the fiber
cables before you plug them back into the optical bores of another SFP module.
Avoid getting dust and other contaminants into the optical bores of your SFP
modules: The optics do not work correctly when obstructed with dust.
Warning
Because invisible laser radiation may be emitted from the aperture of the port
when no cable is connected, avoid exposure to laser radiation and do not stare
into open apertures.
