Up to eight 3Com Switch 4500 units can be interconnected to create a stack and
then treated as a single manageable unit with one IP address.
You can interconnect your Switches to create a stack using a standard 1000 Mbps
Ethernet connection.
You can only create a stack by interconnecting a 3Com Switch 4500 with other
3Com Switch 4500s.
This section assumes you have either set up your units for management as detailed
in Chapter 3 "Managing Your Switch"or that you are using a console cable
connected to the console port to set up and allocate IP addresses and so on.
3Com recommends that you do not physically connect the cables on your stack
ports until you have carried out the initial configuration of the stack ports as
detailed below.
1 Ensure that the Switch units that you wish to interconnect have the latest software
agent installed. You can use the display version command to check this.
2 Enable the 'up port' and the 'down port' on each Switch to operate in stack mode
using the following CLI command. From the System View enter stack-port
gigabitethernet 1/0/51 enable, for example.
As with all Switch 4500 CLI commands, the format for entering a port- specific
command is x/y/z, where x = unit number, y = module number (in the case of the
Switch 4500 this will always be 0), z = port number.
3 Connect the stack-enabled 'up' port on one Switch 4500 unit to the stack-enabled
'down' port on another Switch 4500 unit using the appropriate connection
method for your Switch.
4 Save all configuration settings. From the User View, enter the save command to
save the configuration to your Switch.
This section offers some guidelines for creating a stack. Using these guidelines will
help prevent problems arising when setting up your stack.
