The optional Stacking Module allows up to eigh
t
DES-3226S Switches to be interconnected via thei
r
individual stacking modules. This forms an eight-
Switch stack that can then be managed an
d
configured as thought the entire stack were a single
Switch. The Switch stack is then accessed through
a
single IP address or alternatively, through the maste
r
Switch’s serial port (via the management station’s
console and the Switch’s Command Line Interface).
The stacking module’s LED indicators are describe
d
below.
The stacking ports are marked IN and OUT. The IEEE 1394 com
p
liant
cable must be connected from an IN port on one Switch to an OUT
p
ort o
n
the next Switch in the stack. The last two Switches (at the top and bottom o
f
the stack) must also be connected from the IN
p
ort on one Switch to the
OUT port on the other Switch. In this way, a loop is made such that all o
f
the Switches in the Switch stack have the IN stacking port connected to
another Switch’s OUT stacking port.
