D3LX CO and RMT Modules August 30, 2002 15
3 Locate the mounting slots designated for the D3LX RMT modules in the chassis. If protection switching is
required, a working module installs in the first slot of a quad group, such as 1-1 or 2-1. The protection module
installs in the slot to the right of the working module, slot 1-2 or 2-2.
4 Refer to Figure 9 for D3LX RMT module locations chassis and slot corresponding to the DS3 signal.
– If no protection switching is required, proceed to the next step.
– If protection switching is required, a working module may be installed in the first slot of any quad group,
such as 1-1 or 2-1. The protection module is installed in the slot to its immediate right in the order of 1-3
or 2-3. For more information on protection switching, refer to “Protection Switching” on page 4.
Install the working module first, then the protect module.
5 Remove a new module from its protective ESD packaging. If the module is installed, remove it and inspect
for physical damage.
6 Align the module with the slot and slide the module into the chassis until about three inches protrude from
the front of the chassis. Do not seat module in connector at this time.
7 Remove the protective dust cap from the connector on the D3LX RMT module.
