Updated 9/10/2015
For the XPR system the operating systems Windows Server 2003 (R2) and
Windows Server 2008 are recommended for new installations. The hardware
used must have been tested and released by the producer of the operating
system. Please also read the note in Section 2.1.1, “Hardware Environment at
Installation Site”, on page 23 on this.
The following minimum requirements should be met: • Processor
• At least Intel Pentium 4 (or compatible) (Xeon processor or dual core
system), at least 2 GHz
• Using T.38 Fax on more than two parallel lines requires a server with at
least 2 GHz, at least 2 GB RAM and at least one dual core system
• For conference usage one additional core per 50 voice channels
• Using OpenScape Web Client requires a powerful processor depending
on the number of users and sessions. The performance requirements per
OpenScape Web Client user is approximately twice as high as for an
optiClient 130 user. • Working memory
• 2 GB (recommendation: 4 GB)
• in case of TTS usage
• additional 100 MB per installed TTS voice of Nuance Vocalizer for
Network 5 and
• additional 2 MB per channel
at least, however, 1 GB in addition
• in case of ASR usage 512 MB in addition
• in case of conference usage 2 GB in addition
• in case of OpenScape Web Client usage at least 1 GB in addition • Hard disks
2 hard disks with at least 100 GB (IDE or SCSI) each.
Be sure that the partition on which the XPR server software is installed has a
minimum size of 10 GB. The target path must not contain any blanks (e. g.
c:\SiemensOs Xpressions\xpr)! • Second hard disk for data backup recommended • USB slot for installing the XPR from USB • LAN
Ethernet 100 Base T or Gigabit
• The network board must be connected with the LAN to ensure trouble-free
XPR server booting.
• The network board settings must correspond to those of the router/HUB.
• An MS Loopback Adapter must be installed (cf. Section 2.1.3, “Checking
Windows 2008 64-bit Server Settings”, on page 28, point Installing the
Microsoft Loopback Adapter).
NOTE: In Microsoft Windows Server 2012 R2, the Loopback Adapter is
called Microsoft KM-TEST Loopback Adapter.
• If the web conference server is installed on the computer that also hosts
the XPR server, the following requirements must have been complied
with:
• The computer must have two IP addresses or two DNS host entries
that point to the same IP address.
• Port 80 (TCP) and port 5000 (TCP) must be accessible.
IMPORTANT: Protocol IPv6 must be disabled.
IMPORTANT: When replacing the network board or modifying the configuration
(hardware), the MAC-ID used must be checked as it may have
changed and a new license file may have to be created. In this case, the old
MAC ID is disabled and no further license files may be generated for this MAC
ID. Likewise, the licenses for this MAC-ID can no longer be extended. • Slots
When using ISDN boards, PCI respectively PCIe slots are required
depending on the boards to be deployed. Operating systems
Refer to the service documentation OpenScape Xpressions Release Notice
for details about the supported operating systems.
IMPORTANT: Be sure that the partition on which the XPR server software is
installed has a minimum size of 10 GB. The target path must not contain any
blanks (e. g. c:\OpenScape Xpressions\xpr)!
IMPORTANT: The installation of an XPR system on substituted drives is not
possible, since the setup program cannot create the required directory shares of
the XPR system.
IMPORTANT: Installing the XPR system on a domain controller is not permitted.
IMPORTANT: You may not set up an XPR on a computer on which a ComAssistant
is installed. In this context it is irrelevant whether or not the XPR is
integrated in the ComAssistant.
Communication hardware when using an ISDN connection
To address the XPR system via the telephone user interface (TUI) and/or to be
able to send and receive fax messages, you need at least one S0 or S2 board by
Dialogic/Eicon for mounting in the server PC.
Dialogic/Eicon ISDN boards
IMPORTANT: At times, Dialogic uses different version numbers for the same
board. For example, the hardware description features a specific version number
for a board, but in the Dialogic Diva Configuration Manager you find another
version number for the same board. The version numbers used for Dialogic ISDN
boards in this XPR V7 guide are always the version numbers specified in the
Dialogic Diva Configuration Manager!
Refer to the OpenScape Xpressions Release Notice for a list of the supported
Dialogic/Eicon ISDN boards.
Mixed operation between different BRI or PRI cards as well as mixed operation
of BRI and PRI cards on a server computer is not released.
IMPORTANT: Using more than 3 Dialogic/Eicon-4BRI boards in the CorNet-T
context may lead to a faulty call forwarding connection. Please note the
workaround in Section C.6, “Hicom 300H/CorNet-T Installation”, on page 308.
