• Base MAC Address — Displays the device MAC address. If the system is in stack mode, the Base
MAC Address of the master unit is displayed.
• Hardware Version — Displays the hardware version number. If the system is in stack mode, the
hardware version of the master unit is displayed.
• Software Version — Displays the software version number. If the system is in stack mode, the
version of the master unit is displayed.
• Boot Version — Indicates the system boot version currently running on the device. If the system is
in stack mode, the version of the master unit is displayed.
• Switch Operation Mode After Reset — Indicates the mode the device operates in after the system
is reset. A switch may operate in one of two modes: stack or standalone. Either mode is selected by
the user during software boot or in the web interface’s System Information page. The new mode
takes effect after the unit is reset. The factory default is stack mode. The possible field values are:
– Standalone — Indicates the device operates as a Standalone device after the system is reset.
A switch operating in standalone mode runs as an independent, single unit. All ports of a
standalone switch operate as normal Ethernet links. A standalone switch does not participate
in a stack even if physically connected to a stack.
– Stack — Indicates the device operates as a Stacked unit after the system is reset. A switch
operating in stack mode is not an independent unit, but a member of an organized group of
switches known as a stack. A stack consists of one Stack Master control switch, one Master
Backup switch and up to six Stack Member switches. In some cases, a unit in stack mode
that is not connected to any other units may operate as a “stack–of-one.”

Managing Stacks
Stacking allows you to build a switch with many more ports than would be available in a single unit. The
stack is managed by one of the units (called the Stack Master) and all of the other units serve as ports
only.
You can build stacks by building a new stack from a group of switches, or adding new units to an
existing stack. Stacks can be automatically or manually configured.
NOTE: Two ports of each unit in a stack mode (ports 12
and 24 on GE units, and ports G1 and G2 on FE units) are
reserved for stacking links, and cannot be used for regular
network connections.
