Use the following steps to install a Line Re-timing Module in an SSU-2000.
1. Align the module card edges with the plastic card guides of the selected slot.
2. Slide the module into the chassis until it seats fully into its rear panel edge
connector.
3. Tighten the captive screws located at the top and bottom of the module front
