Integrating a Secondary Server for Cisco Unity Failover
The Cisco Unity failover feature enables a secondary server to provide voice messaging services when
the primary server becomes inactive. For information on installing a secondary server for failover, refer
to the applicable Cisco Unity installation guide, available at
http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.
For information on failover, refer to the Cisco Unity Failover and Configuration Guide. The Domino
version of the guide is available at
http://www.cisco.com/univercd/cc/td/doc/product/voice/c_unity/fail/fail401/dom/index.htm. The
Exchange version of the guide is available at
http://www.cisco.com/univercd/cc/td/doc/product/voice/c_unity/fail/fail401/ex/index.htm.
Requirements
The following components are required to integrate a secondary server:
Phone System
• A serial data port for the data link.
• A data splitter unit to split the single data link into two serial cables.
• Two additional RS-232 serial cables (to be used with the serial cable from the integration of the
primary server). With the three serial cables, connect one from the data port in the phone system to
the data splitter unit; connect the second from the data splitter unit to the serial port on the primary
server; and connect the third from the data splitter unit to the serial port on the secondary server.
Cisco Unity Server
• One secondary server for each primary server installed and ready for the integration, as described
in the applicable Cisco Unity installation guide and earlier in this integration guide.
• The applicable cable configuration for each analog voice messaging port to simultaneously connect
the phone system to the corresponding ports on both the primary and the secondary servers. For
example, connect port 1 on the phone system with both port 1 on the primary server and port 1 on
the secondary server.
• A license that enables failover.
Integration Description
The phone system uses a data link to send call information to the primary and secondary servers. The
data splitter unit splits the single serial cable into two serial cables, enabling the data link to connect to
the primary and secondary servers. The analog voice messaging lines from the phone system provide
voice connectivity to the primary and secondary servers. Figure 2 shows the required connections.
