VCCI Class A Statement
This is a Class A product based on the standard of the Voluntary Control Council 
For Interference by Information Technology Equipment (VCCI). If this equipment 
is used in a domestic environment, radio disturbance may arise. When such 
trouble occurs, the user may be required to take corrective actions.
Laser Safety Information
This product uses Class 1 laser optical transceivers to communicate over the fiber 
optic conductors. The U.S. Department of Health and Human Services (DHHS) 
does not consider Class 1 lasers to be hazardous. The International 
Electrotechnical Commission (IEC) 825 Laser Safety Standard requires labeling in 
English, German, Finnish, and French stating that the product uses Class 1 
lasers. Because it is impractical to label the transceivers, the following label is 
provided in this manual.
Electrostatic Discharge Sensitivity (ESDS) 
Precautions
The assemblies used in the switch chassis are ESD sensitive. Observe ESD 
handling procedures when handling any assembly used in the switch chassis.
