SC300E MPP Processor Module

TECHNICAL DESCRIPTIO

Physical

The MPP is a 9U high PCB with integral front panel. Some aspects of MPP operation are determined

link settings.

External connections

Each module is plugged into the main chassis backplane bus system via two DIN41612 connectors J1 and J2 (Figure 1-1 ). Figure 2-1 shows the main chassis backplane bus interconnections.

Diagnostic port

A 9-pin D-type connector is provided on the front panel. The pinout is listed in Table 2-4. The diagnostic port signals are also available at connector ‘g’ at the rear of the chassis backplane

(Tabl

e 2-5).

Chassis backplane

The signals passing through J2 are available at the rear of the main chassis backplane. The rear backplane connectors are shown in Figure 2-2 Chassis User Manual (Ref 008-5097).

. For additional information, refer to the

Connector J1 links the MPP to the I/O modules and is represented on the rear of the chassis backplane (96 pins in three columns a, b and c). Pins 07 to 10 of columns ‘b’ and ‘c’ are extended to enable the installation of the chassis address setting links (see Figure 2-5).

Column ‘b’ of connectors J2 links each MPP to the other MPPs via the Inter-Processor

Communications Bus.

Columns ‘a’ and ‘c’ of connectors J2 link each MPP to the expansion bus via rear backplane connectors

Area ‘d’. Area ‘d’ consists of extensions to the pins of the J1 mating connector

‘e’.
