Setting Up a Stacked Configuration

Setting Up a Stacked Configuration

Rack Mounting Stacked Configurations

To rack mount a stacked configuration, install all switches that are to be included in the stacked configura-
tion as described on pages
chassis.
Note. When rack mounting multiple switches in a stacked configuration, be sure to place all switches in
vertically-adjacent rack positions. This will ensure that all required stacking cables will have adequate
length for the installation.
Important Note. OmniSwitch 6800-U24 switches do not support stacking.

Cabling Stacked Configurations

In order to connect stacked switches into a virtual chassis, all modules in the stack must be connected via
stacking cables (provided).

Redundant Stacking Cable Connections

In addition to the stacking cables installed between adjacent switch, the top-most switch and bottom-most
switch in the stack must be connected using a redundant stacking cable. Refer to
OmniSwitch 6800 Series Stacks"

Supported Cabling Patterns

Each switch provides two stacking ports: stacking port A and stacking port B. Cables can be connected in
any pattern. In other words, the cable connected to stacking port A of one switch can be connected to
either stacking port A or stacking port B of the adjacent switch. However, it is strongly recommended that
the cabling pattern remains consistent across the stack. For a cabling diagram and additional information
on cabling the stack, refer to
Cabling Steps
1 Before inserting a stacking cable into one of the stacking ports, be sure to orient the stacking cable
connector properly. The wide portion of the connector must be facing up. Refer to the diagram below for
more information.

for more information on the redundant stacking cable connection.
Chapter 3, "Managing OmniSwitch 6800 Series Stacks."
When orienting the stacking cable connector, be sure
that the wider portion of the connector is facing up,
as shown. Otherwise, the stacking cable will not fit
properly in the chassis' stacking port.
