Netra CP2140 Board Specifications

This chapter provides the Netra CP2140 board specifications.

3.1 Board Features and Specifications

TABLE 3-1 shows the physical dimensions of the CPU board.


CPU Board Parameter	6U CompactPCI Form Factor
Height	233.35 mm
Depth	160 mm
Width	19.80 mm

Described below is some information on CompactPCI height restrictions and the Netra CP2140 board standard components.

The CompactPCI standard, PICMG 2.0 Rev 3, calls out the maximum component heights of 13.71 +/- 0.03 mm. Due to variations in parts, board flatness, board thickness, and manufacturing tolerances, the stacked height of two expansion memory boards and memory turrets installed on a CP2140 board may exceed this limit.

PICMG 2.0 R3 and IEEE 1101.10-1996 require 2.54mm between the top of components and the separation plane, and there is at least approximately 0.5mm to 2mm of clearance to solder-side components or leads of an adjacent board from that same separation plane. Therefore, there is very little chance that a small specification violation will impact an adjacent card in a PICMG 2.0 R3 compliant chassis.

Care should be taken when installing the boards in systems that have extreme solder-side component heights or in system chassis that don't allow clearances specified in the PICMG or IEEE standards.

TABLE 3-2 shows the system compatibility attributes.

TABLE 3-6 shows the Netra CP2140 board memory module configurations.


Bottom SDRAM Module PN and Specification	Top SDRAM Module PN and Specification	Total Memory Available on Board
375-3025-xx 512MB	375-3025-xx 512MB	1024MB
375-3026-xx ^[1] 1024MB	375-3026-xx 1024MB	2048MB

Note - The memory module configurations provided in TABLE 3-6 are the configurations that have been tested and are supported. Other memory configurations are possible on the Netra CP2140 board but customers will not receive technical support if they use other memory configurations.

Any two modules in any supported memory configuration can be installed in any combination (512 Mbyte, 1 Gbyte). However, if two memory modules need to be installed and one of the modules is double-sized, it should be installed on the bottom.

If a double-sized memory module is installed on the Netra CP2140 board, then the installation of a PMC card is not supported.

For detailed information on installation and removal of memory modules, see 256/512 MB Memory Module Installation and Removal Guide for Netra CP2000/CP2100 Series Compact Boards (816-0854-xx) and 1 GB Memory Module Installation and Removal Guide for Netra CP2000/CP2100 Series CompactPCI Boards (816-2917-xx).
