The shelf and multiplexers are passive equipment and require no power or
electronic This chapter describes how to install optical routing components, and
includes the following topics.
• “Preparing for installation” next
• “Installing the shelf” on page 37

Preparing for installation
Before installing the optical routing system, observe the following:
• “Exceeding class 1 power level warning” next
• “Environmental and physical requirements” on page 36
• “Electrostatic discharge” on page 36
• “Handling and cleaning fiber optic equipment” on page 49
Exceeding class 1 power level warning
Muxing together several CWDM GBICs can produce a radiant power level in the
fiber which exceeds the class 1 laser Limit. The warning in
Figure 14 appears on
the CWDM OMUX.
