This procedure is divided into the following phases:
 Phase 1: "Uploading the Active Configuration File" on page 78
 Phase 2: "Removing the Current Master Switch" on page 79
 Phase 3: "Configuring the New Master Switch" on page 84
 Phase 4: "Connecting the New Master Switch to the Stack" on page 86
The phases should be performed in the order presented here.
The first step to replacing the master switch of a stack is to upload the
active configuration file to your workstation or, alternatively, to a TFTP
server. The file contains the configuration settings of all the switches in the
stack. Later in these procedures you will download the file to the new
master switch.
If the current master switch is nonfunctional, perform this procedure on the
backup master switch, which has the stack ID number 2. The backup
master switch keeps a copy of the configuration file so that if the master
switch fails, it can assume the role as the master switch.
You can upload the file using either Xmodem or TFTP. This procedure
uses Xmodem. If you prefer to use TFTP, refer to the AT-S63
Management Software User's Guides for instructions.
To upload the active configuration file from the master switch or the
backup master switch, perform the following procedure:
1. Start a local management session on the current master switch or, if
the master switch is not functional, on the backup master switch (stack
ID 2). For instructions, refer to "Starting a Local Management Session"
on page 52.
2. To identify the name of the active configuration file, enter this
command:
show stack
Here is an example of the information the command displays.
