Installing the Catalyst Switch Rear Stack Port Expansion Module
ThefollowingsectionexplainstheinstallationanduseoftheCatalystStackPortconnectionmodule,
which enables two or more Catalyst switches to work together as a Stack.
Catalyst Stack Port
The Catalyst Stack Port is a single-port expansion module with a special 50-pin connector. (For a
detailed description of the Catalyst Stack refer to the Catalyst Stack Installation and Configuration
Guide for your particular model.) With the Catalyst Stack Port, two types of Stacks can be created:
•Two Catalyst switches, each equipped with a Catalyst Stack Port module, can be combined into
a back-to-back Stack by connecting each module together using a single Stack Port cable. For
cablingtheStack Port module, see the following section, “Catalyst Stack Port Expansion Module
Cables.”
•More than two Catalyst switches, each equipped with a Catalyst Stack Port module, can be
combined into a Stack by connecting each module to a Catalyst Matrix unit. The Catalyst Matrix
supports a Stack of up to eight Catalyst switches.
Inserting the Catalyst Stack Port
The module can be inserted in its expansion slot as shown in Figure 2.

Caution Catalyst Stack Port modules are not hot-swappable. Always be sure that the power is off
before installing or removing a Catalyst Stack Port module. If the power is on, damage to the
equipment may result.
Caution Do not touch the components or connectors on the Catalyst Stack Port module. Do not
touch the connector pins on a cable when the other end is plugged into a component. Damage may
result from static discharge.
Caution During installation, the connector on the Catalyst Stack Port module must line up evenly
with the connector inside the expansion slot. Misalignment may cause the connector pins to bend.
When inserting the Catalyst Stack Port module into the expansion slot, be sure that the board is level
and that the left and right sides slide evenly into the slot.
