System Cabinets; Processor Cards - Samsung OfficeServ 7200 General Description Manual

PART 2. HARDWARE DESCRIPTIONS

2.1 SYSTEM CABINETS

The cabinets that make up the OfficeServ 7200 system are of metal construction and may be utilized as either as
an expansion cabinet or as a main cabinet / key service unit (KSU). The cabinets may be used individually or may
be stacked up to two (2) high to achieve maximum capacity. A single cabinet may be wall mounted for smaller
applications or alternatively the system may be mounted in a standard nineteen inch (19") equipment rack. Each
cabinet is comprised of the following:
• Five (5) universal interface card slots
• One processor card slot
• One power supply (installed in back panel of the cabinet)
• AC power connector
• DC power (Battery Backup) connector

2.2 PROCESSOR CARDS

The OfficeServ 7200 requires a processor card in order to operate. In a single cabinet OfficeServ 7200 system, only
one processor card, the Main Control Processor (MP20), is required. Each expansion cabinet requires its own Local
Control Processor (LCP). These processor cards are described below.
MAIN CONTROL PROCESSOR (MP20)
The Main Control Processor (MP20) is installed the dedicated processor slot, slot 0, of the first cabinet and has
positions for three daughter boards. The first daughter board position (labeled "MIS") can support the MIS daugh-
ter board ONLY. The second daughter board position is only for the RCM2 or CRM daughter boards. The third
daughter board position is dedicated only for the CRM daughter board or modem board.
The MP20 includes without additional daughter boards the following common system resources:
• 4 DTMF Receiver
• 32 DTMF Senders
• 6 Five Party Conference Groups
The MP20 is using a MPC8247 processor chip for improved performance and is using SRAM and NAND flash
memory. The SRAM has been increased from 64MB to 128MB of memory. The backup memory is using NAND
flash memory and does not have a super capacitor for database backup. The MP20 also supports the Samsung
modem card for remote access and now supports the CRM (Common Resource Module). The memory clear but-
ton has been replaced with the new functionality on the (RST) to default the system. The database will do a back-
up every 5 minutes from SRAM to NAND flash memory or when the user disables MMC 800 in programming.
Important Note: The MP20 requires a Secure Digital (SD) media card with proprietary Samsung format. This is the
standard media card for the OfficeServ 7200 system. The card has a switch that can put it into a READ ONLY state
what will not allow a backup database to be created. Make sure the switch is in write mode (position the switch
toward the contact pins).
