OfficeServ 7400 INSTALLATIONTECHNICAL MANUAL PART 3 MAY 20103.4IMPORTANT: The OS7200 MCP/MP20, 4WLI and WIM module are NOT allowed in an OS7400 system. Although the MGI64 and TEPRI2 can be installed in any universal slot of the OS7400expansion cabinet, it is recommended that they be installed in the main cabinet in orderto utilize the full capacity of the cards. The main cabinet slots are 64 channel slots and theexpansion cabinet slots are only 32 channels. Therefore, installing a TEPRI2 or MGI64 inthe expansion cabinets will only give you half of the capacity for these cards. Installingthem in the main cabinet will give you the full capacity of these cards. A maximum of 1 GWIM/GWIMT per cabinet and 2 GSIMs per cabinet can be installed.Every OS7400 cabinet must have an LP40 card installed in slot 0 including themain cabinet. Even a single cabinet system requires an LP40 card.
