Stacking concepts
A single switch can control and manage a stack. This switch is referred to as the stack
management switch, or simply, the management switch. Any other switch in the stack
is referred to as a member switch.
Member switches can download firmware from the management switch and the
management switch can push firmware to the member switches.
The management switch runs the fully operational software of a switch. In addition, the
management switch runs the management switch software of the distributed switching
application that configures and manages all member switches. Generally, the
management switch operates the remote member switch’s low-level drivers through
the distributed switching application part that is running in the context of the member
switch.
During stacking setup, the switches autoselect one switch as the management switch.
All other switches become member switches and are assigned unique stack IDs. One
of the member switches is designated as the standby management switch. The standby
management switch functions as a member switch but can become the management
switch if the original management switch fails. In the default configuration, the
management switch and standby management switch are assigned unit IDs of 1 and 2,
respectively. You can use the device user interface (UI) to configure different ID
assignments. The management switch provides a single point of control and
management as well as a single interface through which to control and manage the
stack.
Switch software is downloaded separately for each stack member. However, all stack
members must be running the same software version.
A stack unit can operate in one of the following modes:
•A standalone switch runs as a general switch. The standalone unit does not run the
stacking application until it is connected to a stack.
Hardware Installation Guide8Introduction
Fully Managed Switches M4350 Series

•A management switch manages the entire stack and is responsible for the entire
stack configuration. All protocols run in the context of the management switch, which
updates and synchronizes the standby management switch.
•A standby management switch runs as a member switch until it must take over from
the management switch. In addition, the standby management switch continuously
monitors the existence and operation of the management switch. If the management
switch fails, the standby management switch assumes the role of management switch
through a switchover.
•A member switch runs only a member switch version of the distributed switching
software, which allows the applications running on the management switch to control
and manage the resources of the member switch.
A stack can contain a mix of up to eight switches. All models support stacking. The
management switch supports Nonstop Forwarding Failover (NSF).
Note: A stacking link works only on the highest speed supported by a stack port. For
example, a 25G port that is also capable of operating at 10G speed operates only at
25G speed in stack mode. In Ethernet mode, this limitation does not apply, and the port
can operate at 25G or a lower speed. When you set up a stacking link between two
switches, ensure that both ports can operate at the same speed in stack mode. For
example, set up a stacking link between two ports that each can support a maximum
speed of 25G, or between two ports that each can support a maximum speed of 10G.
For information about how to configure stacking through the software, see the main
user manual, which you can download by visiting downloadcenter.netgear.com.
