CHAPTER 1
GENERAL INFORMATION
The MWF210 consists of a card frame and a front panel. The frame's
size is one half of a 19" rack. Included in the frame is an MWM210
motherboard. The card frame has installation slots for six plug-in
Eurocards and a double slot for the plug-in power supply unit.
Positions of the units in the card frame are shown in Figure 1.
Slots are numbered from left to right (rear view) from 0 to 7.
Positioning of the optional units conforms to the following table:
Table 1 MWF210 Unit Positions

4 MWG203 20
5 MWV201 20
6–7 MWP210 60
CAUTION Do not cover the ventilation holes on top of the unit.
The frame is provided with EMI protection.
The power supply area is protected with particular fire-resisting plates
in the top and bottom. The plates also prevent small objects from
falling through the ventilation holes into the mains voltage circuitry of
the power supply.
The enclosed drawing illustrates the assembly of the frame.

Motherboard
The operating voltages as well as signals between different units are
carried through Motherboard MWM210. The motherboard does not
contain any electronic or electromechanical components other than the
interconnecting system connectors for the plug-in units and the signal
and power connectors for the front panel. Front panel power connector
is not used in the MWF210.
The following table describes the main common signals connected to
all plug-in units in the motherboard.

Front Panel
The Front Panel contains a power control switch and an indicator
lamp mounted in the Switch and LED board MW45109. After mains
cord connection the system automatically enters stand-by (STBY)
state, where the power control logic in power supply is alive, but the
plug-in units are not powered and the indicator lamp is not lit.
Pressing the power switch once puts the system into power-on state
(PWRON) and the indicator lamp is lit. The next pressing of the
switch will bring the system back into stand-by state.
