Explained
Stack Management Units in the Switch 1100/3300 family can be interconnected so that they
form a stack, that is, a group of devices that are managed as a single
device.
Stackability is not supported by the Switch 610/630 units.
You can interconnect these Switch units together in two ways:
■
The matrix port on the rear of each Switch allows you to connect two
Switch units back-to-back. For this you need a Matrix Cable (part
number 3C16965).
■
The Expansion Module slot at the rear of each Switch allows you to
install a Matrix Module (part number 3C16960). The Matrix Module
provides four ports and allows you to interconnect up to four units
using Matrix Cables.
For information about stacking Switch units, refer to Chapter 2 of the
relevant Switch User Guide.
Forwarding Modes Units in the Switch 3300/630 family support Store and Forward packet
forwarding mode. In this mode, received packets are buffered entirely
before they are forwarded, which ensures that only good packets are
forwarded to their destination.
