5-14 Procedures after Completion of Installation

Setting up PCs on a Network

If you have computers running on Windows Server 2003, Windows XP/2000/NT4.0, Windows

95/98 that communicate with NEC Express5800/ft series using the TCP/IP protocol, make the

following settings on all computers.

1. Copy the following in the NEC EXPRESSBUILDER CD-ROM or ft control software,

UPDATE CD-ROM to any directory.

\STRATUS\LANG\EN\PROG\FTREG.EXE

TIPS: ft Update CD is for updating ft control software. It may not be attached to the

product. If software included in the NEC EXPRESSBUILDER CD-ROM is latest at

the time of shipment, the ft Update CD is not attached.

2. Start up the command prompt and enter the directory in which the file mentioned above is

copied, and then enter the following command.

FTREG.EXE

This setting is to avoid a timeout caused by non-communication state between the NEC

Express5800/ft series and computers connected by the LAN protocol that may occur immediately

after the NEC Express5800/ft series startup or a CPU module reinstallation (dual processing).

Non-communication time immediately after the NEC Express5800/ft series startup or module

reinstallation in the system where Windows Server 2003 runs is proportional to the size of memory

mounted and how much applications running use memory.

Because minimum non-communication time is momentary regardless of size of the memory

installed, it will not be considered as non-communication. Maximum non-communication time by

the memory size is as follows:

Memory size Non-communication time

256MB About 3.1 seconds

512MB About 6.2 seconds

1GB About 12.3 seconds

2GB About 24.7 seconds

3GB About 36.3 seconds

6GB About 47.0 seconds

This setup program sets the following Windows registry:

 Windows XP/Windows NT/Windows 2000/Windows Server 2003:

Registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

Values: TcpMaxConnectRetransmissions

Type: REG_DWORD

Set value: 5

Values: TcpMaxDataRetransmissions

Type: REG_DWORD

Set value: 8

Values: TcpMaxConnectREsponseRetransmissions

1 2 ... 111 112 113 114 115 116 117 118 119 120 121 ... 144 145
