Chapter 3Installing Printed Circuit Cards
Before installing each card, unpack it and check it for signs of physical damage. If you detect any
problem, call Samsung Technical Support immediately.
MCP
The iDCS 500 Main Control Processor (MCP) controls the system operation. The MCP installs in the
MCP/LCP slot in the first cabinet of the system. The MCP is required for all system configurations.
The MCP has a 512 channel time switch matrix and positions for 3 daughter boards. With a multiple
cabinet system a ESM daughter board must be installed on the MCP to expand the switch matrix.
The MCP supports the following options.
y8 position DIP Switch
yMemory Backup On/Off Switch
ySmartMedia card slot
y12 LED’s
y3 daughter board positions, one with external connections to support a MISC
yMOH Internal Melody
y2 SIO circuits
Figure 3-1 MCP Card
12 LED’s give operational status of the CPU, SmartMedia status, LAN status and the status of card
slots 1~9. These are stenciled on the face of the MCP card. The LED indications are as follows:

DRAM, 3 synchronous communication ports for inter processor communications. This
board is required for multiple cabinet systems.
yLAN : 10BASE-T LAN Interface, 0.5 Megabytes of SRAM, 2 Serial I/O circuits.
yESM : Increases the system to 1024 channel time switch. This board is required for multiple cabinet
systems.

When it is set to "ON" and the version of SMARTMEDIA is not match to current system version,
system S/W will be replaced to the S/W of SMARTMEDIA.
yThese DIP switches will not take effect unless the switches are set in the wanted position and the
system memory is cleared manually by using the Memory Backup switch.
Install the SmartMedia card. Install daughter board(s). Set the MCP DIP switches on the card to the
desired positions.
Insert MCP card in the CAB slot labeled MCP/LCP (see Figure 3-2). Push firmly at the top and bottom
of the card to ensure that it is fully inserted into the back plane connector. To prevent accidental
damage to the MCP card, the MCP/LCP connector on the back plane is positioned to mate only with
the MCP or LCP card. Other interface cards will not mate with this connector and the MCP card will
not mate with any other connector.
NOTE: Do not insert this card with system power ON.

SCP CARD
The iDCS 500 Switch Control Processor (SCP) is used when the system is expanded to more than one
cabinet. In a multiple cabinet system the SCP becomes the processor for the first iDCS 500 cabinet
and communicates via a high speed data link to the MCP. The SCP installs in the ninth (9) slot in the
first cabinet. The SCP can have three daughter boards installed as indicated by the table below.

LCP CARD
The iDCS 500 Local Control Processor (LCP) is used when the system is expanded to more than one
cabinet. The LCP is the processor for the second and or third iDCS 500 cabinet(s) and communicates
via a high-speed data link to the MCP. The LCP installs in the MCP/LCP slot in the second or third
cabinets of a multiple cabinet system. The SCP can have three daughter boards installed as indicated
by the table below.

Push firmly at the top and bottom of the card to ensure that it is fully inserted into the back plane
connector. Connect the iDCS 500 Inter-Processor Connection cable (CIC) to the front of the LCP.
Connect the opposite end of the CIC to the connector on the front of the MCP. Connect the second
CIC in a similar manner between LCP cards. The CIC is supplied with the LCP.

NOTE: Do not insert this card with system power ON.
To prevent accidental damage to the LCP card, the MCP/LCP connector on the back plane is
positioned to mate only with the MCP or LCP card. Other interface cards will not mate with this
connector and the MCP or LCP card will not mate with any other connector.
There are twelve (12) LED indicators on the front of the LCP card. The uses are as follows:
LCP HDLC TX (Transmit) Status
OFF indicates that there is no link from the LCP card

ESM BOARD
This board has no selectable options and installs in position LOC1 of the MCP card when the system
has more than one cabinet installed (see Figure 3-2). The ESM board is required to expand the system
from 512 to 1024 time slots. To install the ESM board remove the two (2) screws holding the MCP
protective casing together (see Figure 3-6) and separate the two halves of the case. Place the ESM
board face down over the three connectors, taking care to properly line them up and press gently on
the back of the board to seat it. The MCP case can now be reassembled if all required daughter
boards have been installed.
