412-Slot VMEbus Backplane 4 Overview This chapter provides a physical and electrical description of the 12-slot VME bus backplane used in the MVME956AC chassis. Refer to Chapter 1 for features and specifications of the backplane. Refer to Chapter 6 for removal and replacement procedures. Physical Description The backplane was designed to accommodate VME modules and disk drive units. It accommodates up to 12 double-high user VME modules containing both P1 and P2 connectors.
12-Slot VMEbus Backplane Backplane Bus Connectors All rows of J101 through J112 (Z, A, B, C, D) are interconnected across all 12 slots, which provides the required signals for A24/D16 operation. The center row (B) of J201 through J212 is interconnected across all 12 slots, which provides the required signals for extended operation (A32/D32). 4 Rows A and C of J201 through J212 are not interconnected, but are available for I/O functions or expansion bus operation.
Backplane Preparation Backplane Preparation The chassis is shipped from the factory with the backplane fully equipped with sockets (VME64X bus connectors), power connectors, and bus terminator resistor networks. No special preparation or preassembly is required prior to use. You must configure the VME64X bus daisy-chain jumpers on the rear (wire side) of the backplane. Refer to VITA 1.x Live Insertion for VME64x requirements standard for more electrical detail and information on daisychain jumpering.
12-Slot VMEbus Backplane - V2 PB1 J1 + V1 PB4 +3. 3V PB5 +3. 3V PB6 +3. 3V PB7 +3.
Install the Daisy-Chain Jumpers Install the Daisy-Chain Jumpers All daisy-chain lines of the VME64x bus can be separately bypassed with removable shorting jumpers on every connector socket. Shorting the input to the output of the daisy-chain signals is required if the daisy-chains are in use, and if a VME64x module design does not provide for the propagation of the daisy-chain.
12-Slot VMEbus Backplane – Row of pins, left side of slot J103 - BG0, BG1, ... – Row of pins, left side of slot J106 - BG0, BG1, ... Carefully align the jumper(s) on the correct pair of pins to be jumpered and gently push until the top of the jumper is flush with the top of the pins. 4 4. Continue in this fashion, placing jumpers on all pairs of pins for each backplane slot that will not be occupied by a VME64x module.
Install the Daisy-Chain Jumpers Live Insertion Sockets J4-J14 allow the daisy-chained bus grant arbitration and interrupt priority resolution processes to continue unaffected during live insertion or removal. These sockets, in conjunction with the headers for bus grant signal jumpers and the headers for IACK signal jumpers can be used with a user-supplied daisy-chain switch module. This switch module incorporates the backplane daisy-chain bypass circuits. Table 4-2.
