Existing Ess Server To Main Server - Avaya ESS User Manual

Enterprise Survivable Server Conversions
6. All conversion options including the Main server(s) (non ESS server to Main server, ESS
server to Main server, and Main server to ESS server) will be service affecting. When Port
Networks are controlled by a new media server (Main server or ESS server), they preform a
restart which resets every board in the Port Network.
7. IP server interface (IPSI) circuit packs may require a firmware upgrade to be compatible
with the ESS feature. See the Minimum Firmware/Hardware Vintages document found at:

Existing ESS server to Main server

Note:
Manual Backup Servers and the Enterprise Survivable Server functionality can
Note:
not be implemented on the same system.
Note:
Do not use this procedure to convert a Manual Backup Server to a Main server.
Note:

! CAUTION:
This procedure is service affecting. Because a new Main server is coming on line,
CAUTION:
Port Networks that are being controlled by other servers will eventually get
switched to the new Main server. This requires that the Port Networks perform a
reset. It may be advantageous to switch all Port Networks to another ESS server,
if one exists, during the conversion.
One example of when this procedure might be used is when two or more systems are being
combined into one system. An existing Avaya media server could be converted to a Main server
while other media servers could be converted to ESS servers.
!
Important:
If a media server is being converted to replace a previously existing Main server it
Important:
must be of the same model as the original.
To convert an existing media server to a Main server:
1. Backup the translations on the media server to be converted. If the existing Main server is
still in operation, perform a complete backup. If the existing Main server is not in operation,
determine the location of the last known good backup.
2. Verify that the media server to be converted is disconnected from the LAN/WAN.
