Mode FDDI Software 6.2 Release Notes

 

For information about the HSSI module components, refer to Appendix A, “HSSI Module 
Components.”

 

Before you install the HSSI module into the NETBuilder II base system, follow these steps:

 

Electrostatic discharge (ESD) can damage circuit board components. Failures resulting 
from ESD may not be covered under your warranty. To prevent this, follow these handling 
procedures:

 

■

 

Keep the HSSI module in its antistatic shielded bag until you are ready to install it.

 

■

 

Do not touch pins, leads, or solder connections on the board.

 

■

 

Handle the board by the edges only.

 

■

 

Store or ship the HSSI module in static-protective packaging.

Observe proper grounding techniques when handling the HSSI module: Use a foot strap 
and grounded mat, or wear a grounded static discharge wrist strap.

 

If you find any damage, contact the shipping company to file a report. If the assembly 
must be returned to your network supplier, ship it in its original shipping carton. If the 
original carton was damaged in shipment, repack the system in a carton that provides 
equivalent protection.
