Hardware Installation and Functions
Before setting up the 2346, make sure the chassis or enclosure is installed and its User Manual is
available for reference. If the system includes an optional DMM and CIM(s), make sure these are
available:
• Serial cable (required to connect to a VT100 type terminal or PC)
• VT100 type terminal or PC to run the User Interface Manager software
• The DMM and CIM manuals
Set Up and Installation
Unpack and inspect all components. Save the shipping carton and packing materials in case you need
to return the equipment to the manufacturer. Appendix A provides information for Return Material
Authorization (RMA).
1. Before inserting the 2346, check the front panel to verify that the 2346 provides the wavelength
that matches its link partner; see Figure 1.
2. Set SW2-1 and 2-2; see Figure 2.
• SW2-1, Line Buildout (LBO): Off (default) for Short LBO, <225 ft (68 m), or On for Long
LBO, >225 ft; when software control is enabled at the Functional Configuration screen,
SW2-1 is ignored.
• SW2-2, Software override: Off (default) is software, On is hardware; set to Hardware in
unmanaged environment, only. For installation in a managed environment where you plan to
use software control (see page 3-11), set SW 2-2 to Off.
Note: If the 2346 was previously installed in a managed environment and set in the User Interface
to software control, follow these steps to set it to hardware control when installing it in an
unmanaged environment:
a. Set SW2-2 to On.
b. Insert the 2346 in a slot with the power on, then remove it.
c. Set SW2-2 to Off.
d. Insert the 2346 in a slot with the power on, then remove it.
e. Set SW2-2 as needed.
3. Set jumper W10 as needed for normal (to NP) or wide pulse (to WP); see Figure 2. NP is the
default.
