Completing a Stacked Configuration

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 the OmniSwitch 6800 Series Hardware Users Guide
for more information on the redundant stacking cable connec-
tion.

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 recom-
mended that the cabling pattern remains consistent across the
stack. For a cabling diagram and additional information on
cabling the stack, refer to the OmniSwitch 6800 Series Hard-
ware Users Guide.

Cabling Steps

1 Before inserting a stacking cable into one of the stack-
ing 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 informa-
tion.
When orienting the stacking cable
connector, be sure that the wider
Connector Top
portion of the connector is facing up,
as shown. Otherwise, the stacking
cable will not fit properly in the
chassis' stacking port.

2 Starting from the top of the stack, insert one end of the
stacking cable into either stacking port A or stacking port
B. The stacking port (A or B) depends on your preferred
cabling pattern. Refer to the OmniSwitch 6800 Series
Hardware Users Guide for detailed information on
cabling patterns. Be sure that cable connector is
completely inserted and fully seated in the chassis.

Insert the other end of the stacking cable into the stack-
ing port of the switch immediately below. Once again, the
stacking port (A or B) depends on the preferred cabling
pattern.
