Installing the E1 Line Re-timing Module

You can install the E1 LRM in any available I/O slot on both the SSU-2000 shelf and
the SDU-2000 Expansion Shelf. The I/O slots on the SSU-2000 are labeled A3
through A11. The Output slots on the SDU-2000 are labeled A1 through A14.
Note: Modules can be removed and inserted while system power
is supplied without damaging modules.
Caution: For continued EMC compliance, replace all deformed
module gaskets with the same type. Clean gaskets and mating
surfaces. Secure all modules with captive screws.
Use the following steps to install an E1 Line Re-timing module either in an
SSU-2000 or SDU-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.
