Power
The power line filter prevents electromagnetic interference (EMI) from entering the primary power
lines. The power line filter is located at the rear of the cabinet. The AC system power cord plugs into
the power line filter. Some chassis disassembly is required to replace the power line filter. The
voltage rating of the power line filter must agree with the input voltage rating of the Power Supply
Unit (PSU).
. In −48 VDC message servers the power cord is integral with the power line filter.

The Octel 300 has three shelves − Shelf A, Shelf B, and Shelf C − with slots for various
configurations of disk drives and system cards.

- If fax channels are installed, each channel counts against the 128-port maximum.
- For older card-based integrations (ATTIC, SLIC, SIC8, and RIC) maximum voice ports is 96.
