Switch Stacking
The GSW-1290 can be stacked with a GSW-2492, functioning as a Master of the stack. There are two
connection options available to for stacking. One option is to use the built-in combination ports
(1000BASE-T/SFP). The other possibility is to install one or two MDU-1290S stacking modules and
complete the stacking connection through the IEEE 1394 stacking ports. With two stacking modules
installed, the GSW-1290 can be stacked with as many as twelve slave units.
Each optional stacking module allows up to four GSW-2492 Switches to be interconnected in a stack with
the GSW-1290. Two stacking modules may be used to form a nine-Switch stack consisting of one Master
and eight Slaves, managed through the GSW-1290 Master Switch. The stacked group has a single IP
address and is managed as a single device. The entire Switch stack is managed and monitored through the
network or alternatively, through the serial port on the GSW-1290. The stacking modules connect to the
slaves using IEEE 1394 serial cable (Firewire) in a star topology for GSW-2492 groups (see illustration on
page 19).
The stacking ports are marked
IN
and
OUT
. The IEEE 1394 compliant cable must be connected from an
IN
port on one Switch to an
OUT
port on the next Switch in the stack.
Restrictions and Cautions for Stacking
The GSW-1290 may serve as the Master of up to twelve additional Switches. The slave Switch units must
meet the following criteria:
All additional slave Switches must be the same model - that is, the slaves must be all GSW-2492 Switches.
The slave unit types cannot be mixed within a single stacked group. Make sure that all Switches in the
group have the latest firmware installed.
