5. Install a new license file with the appropriate settings for an ESS server. See License
files on page 110 for more information. This license file should probably use the same IPSI
serial number that the previous license file used unless the media server is physically
moved and another IPSI is now logically closer.
The new license file should have the following attributes:
● Enterprise Survivable Server set to y.
● ESS Administration set to Y.
● A Module ID (MID) greater than 1: A MID is also referred to as the Cluster ID (CLID) by
the ESS feature. This value is set by the license file and cannot be administered in
Communication Manager. Each server in a duplex pair (S8700/S8710) will have the
same CLID.
● A System ID (SID): The SID is unique to the system configuration. The Main server and
all ESS servers will have the same SID.
6. Execute this step for
S8500 and S8700 | 8710 active media servers.
Run the Configure Server command from the Maintenance Web Interface. Select the
Configure Individual Services method.
a. Choose - Set Server Identities:
● Enter a unique Server ID (SVID) in the ID field. A single SVID is required for a S8500
media server and two unique SVIDs are required for a
S8700 | 8710 server pair. This ID
must be between 1 and 99. Usually the Main servers are set to SVID 1 and 2.
Gaps in the numbering are allowed (10, 20, 30, . . .) but servers may also be
consecutively numbered.
● Click Continue and verify the IP Addresses.
b. Choose - Configure ESS from the left margin.
Select either:
● This is an enterprise survivable server with an S8700/S8710 media server as the
main server
- When this option is selected enter the IP address of a CLAN that is controlled by
the Main server and the IP address for each of the Main servers.
or
● This is an enterprise survivable server with an S8500 series server as a main
server.
- When this option is selected enter the IP address of a CLAN that is controlled by
the Main server and the IP address for the Main server.
7. For the
S8700 | 8710 media servers perform the same configuration activities as step 6 for the
standby media server.
