5.4 LEI Interfaces
Local Equipment Interconnect ports allow connections from the TE-2020 Main Shelf to an Optical Tribu-
tary Shelf, an ETS1, or to and ETS2. The Tributary Shelves may be remote mounted, meaning they can be
installed in another rack up to 10 cable-meters away from the TE-2020 Main Shelf. This allows customers
to utilize rack space that may have been wasted previously, which saves additional costs for racks and
equipment to support newer installations.
5.5 Shelf Voltage
The following tables identify the voltage requirements for each shelf.
5.6 Fan Power
The following table defines the power consumption for each fan required for the TE-2020 system.

The voltage required for each shelf is -48Vdc. The tol-
erance acceptable for voltage input is shown. Use the
PLM power consumption figures in the following table
to determine the power consumption for a particular
shelf configuration.
