PART 2. HARDWARE DESCRIPTIONS

2.1 SYSTEM CABINETS

The OfficeServ 7400 system has a common universal cabinet design. This cabinet can be configured as the main
cabinet or as an expansion cabinet. Inserting both the MP40 & LP40 cards in specific slots makes it the main cab-
inet. Inserting the LP40 card in a dedicated slot make it an expansion cabinet. The system can be a single cabi-
net or expand to a 3-cabinet system by adding up to 2 additional expansion cabinets. The main cabinet offers 10
universal slots and each expansion 7400 cabinet offers 11 universal slots. Therefore, a 3-cabinet system offers a
total of 32 universal slots. In the main cabinet, all slots are 64-channel slots while the slots in the 7400 expansion
cabinets are 32-channel slots. The OfficeServ 7200 cabinet can also be used as an expansion cabinet. It offers 1
32-channel slot and four 16-channel slots.

2.2 PROCESSOR CARDS

MP40 (MAIN CONTROL PROCESSOR)
This is the main processor controlling system operation. The MP40 always goes in slot 3 of the main cabinet. The
MP40 provides the LP40 link connectors to connect two expansion cabinets, a LAN port, and a smart media card
slot which can accommodate a 32 MB SmartMedia card containing the system software.
The MP40 also has a connector for mounting the optional modem daughter board. This modem board can be
used for remote access to system administration at installations that do not have a LAN or WAN connection. In
addition it may be used as a backup for LAN connectivity. This is the same modem board used with the OfficeServ
500.
LP40 (LOCAL CONTROL PROCESSOR)
The LP40 is a local processor that is required in every cabinet. It must go into slot 0 of each cabinet. Even if you
have a single cabinet system, you must install an LP40. Each LP40 provides 6 five-party conference circuits and 8
DTMF receivers. All system daughter boards are installed on LP40 cards except for the modem daughter board.
