Installation

This chapter contains the following topics:

“Overview” (page 23)

“Nonredundant and redundant server implementations” (page 23)

“Software installation” (page 24)

Overview

After you complete the preinstallation tasks, you install the Nortel Mobile
Communication Gateway 3100 (MCG 3100) software in a nonredundant
or redundant server implementation. During the MCG 3100 software
installation, a number of prompts appear. You can accept the default
value, or enter a new value at each prompt.

Nonredundant and redundant server implementations

For a nonredundant server implementation, install the software on a
standalone server. For a redundant server implementation, install the
software on two servers.

ATTENTION

You must install the license file on each of the servers in a redundant
implementation.

Nonredundant server option

A nonredundant (or standalone) server implementation does not provide
redundancy and therefore provides no failover protection. If a server
component fails or becomes inaccessible, the mobile clients are denied
access until the server recovers.

Redundant server option

A redundant server implementation provides high availability. If an active
server component fails or becomes inaccessible, the mobile clients can
restart a communication session with the backup server.
