Netgear GSM7228PS - ProSAFE 28 ports Gigabit Ethernet L2 Managed Stackable Switch with PoE Guía De Administador

Install the new switch in the rack:

If you are installing the same model switch, put it in the same position in the stack as 

the one that you just removed.

If you are installing a different model switch you can either put it in the same position 

as the previous switch, or at the bottom of the stack.

Cable the new switch, following the established order of stacking cables.

Power up the new switch. Verify, by monitoring the master switch console port, that the new 
switch successfully joins the stack by issuing the show switch command. The new switch 
should join as a member (never as master; the existing master of the stack should not 
change).

If the code version of the newly added member is not the same as the existing stack, update 
the code as described in 

Switch Stack Configuration Files

The configuration files record settings for all global and interface-specific settings that define 
the operation of the stack and individual members. Once a save config command is 
issued, all stack members store a copy of the configuration settings. If a stack master 
becomes unavailable, any stack member assuming the role of stack master will operate from 
the saved configuration files.

When a new, out-of-box switch joins a switch stack, it uses the system-level settings of that 
switch stack. However, if you want it to store this system level configuration, you must issue a 
save config

 command.

You back up and restore the stack configuration using the copy command the same way that 
you would for standalone switch configuration.

The following table provides switch stack configuration scenarios. Most of the scenarios 
assume at least two switches are connected through their stacking ports.

Stack master election specifically 
determined by existing stack 
masters.

Note: This is not recommended.

Connect two powered-on switch stacks 
through the stacking ports.

Only one of the stack masters 
becomes the new stack master. 
No other stack members become 
the stack master.

Stack master election specifically 
determined by the stack member 
priority value.

• Connect two switches through their 

stacking ports.

• Use the global configuration 

command  switch 
stack-member-number priority 

  to set a 

stack member to a higher member 
priority value.

• Restart both stack members at the 

same time.

The stack member with the 
higher-priority value is elected 
stack master.
