HMP Software Release 3.0WIN Release Guide — December 2010

Dialogic Corporation

System Requirements

• IP Network Interface: 100 Base-T Network Interface Card (NIC)

Note: For 120 channels or higher, using a 1000Base-T NIC, while still using a

100Base-T Network, is recommended. In general, better performance will be

realized by using a 1000Base-T NIC, even for configurations of less than 120

channels.

• Dialogic

DNI Boards and Physical Address Extension (PAE): PAE is not supported

on servers having over 4 GB of RAM with a Dialogic

DNI board PCIe form factor and

over 2 GB of RAM with a Dialogic

DNI board PCI form factor. If these configurations

are present, then the Dialogic

HMP system will not start. To prevent this, PAE must

be disabled.

Run the following commands to disable PAE for Windows

7 or Windows Server

2008 operating systems:

bcdedit /set pae ForceDisable

bcdedit /set nx AlwaysOff

Note: Setting “nx” to “AlwaysOff” will disable Data Execution Prevention (DEP).

When DEP is enabled, Windows also enables PAE on machines that are

capable of supporting PAE. When PAE is enabled, Windows may use 36-bit

physical addressing instead of 32-bit, depending on the machine memory.

2.2 Basic Software Requirements

Note: Dialogic

HMP Software Release 3.0WIN has been tested only on systems with NT file

systems (NTFS). This release of the Dialogic

HMP Software has not been tested on

systems with FAT 32 file systems.
