Chapter SGE2000/SGE2000P Gigabit Ethernet Switch Reference Guide 2 • 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." • Jumbo Frames - Enables transporting identical data in fewer frames to ensure less overhead, lower processing time, and fewer interrupts. 2. Define the relevant fields. 3. Click Apply. The system information is defined, and the device is updated. 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.

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.
