Netgear M4300-24X24F (XSM4348S) - Stackable Managed Switch with 48x10G including 24x10GBASE-T and 24xSFP+ Layer 3 Guia Do Administrador

All stack members must run the same firmware version to ensure full compatibility in the 

stack protocol version among the stack members.

If a stack member is running a different firmware version than the stack master, that stack 
member is not allowed to join the stack. To list the stack members and firmware versions, 
issue the show switch command.

If a switch is added to a stack and it does not run the same firmware version as the master, 
the following occurs:

The new unit boots up and becomes a member of the stack.

Ports on the added unit remain in the detached state.

A message displays on the CLI indicating a code (firmware) mismatch with the newly 

added unit.

To enable the newly added unit to merge normally with the stack, issue the copy xmodem | 
ymodem | zmodem | tftp://ip/filepath/filename

 command. This command 

copies the firmware image from a stack member to the one with incompatible firmware. That 
switch automatically reloads and joins the stack as a fully functioning member.

All stack members must run the same firmware version. Ports on stack members that do not 

match the master switch firmware version do not come up. In that situation, the output of the 
show switch

 command shows a code (firmware) mismatch error.

NETGEAR recommends that you schedule the firmware upgrade when 
there is no excessive network traffic (such as a broadcast event).



Using TFTP or xmodem, issue the copy command on the master switch.

After the firmware is successfully loaded onto the master switch, the firmware 

automatically propagates to the other units in the stack.

To avoid errors during firmware propagation, do not move stack cables or 
reconfigure units. 

If an error occurs during firmware propagation, do the following:

a. Check to make sure the master switch is running the correct firmware.
