Preventive Maintenance

Observe the guidelines in Appendix A of the

NETBuilder II Base System Installation

Guide

for minimum and maximum electrical and environmental requirements.

■

Keep the area around the NETBuilder II base system clean and avoid accumulated dust.

This protects the HSSI module from excessively high temperatures.
