For all models, a serial console port on the front panel allows you to connect a terminal and perform
local management. An Ethernet management port can be used to connect the system to a parallel
management network for administration. Alternatively, you can use an Ethernet cable to connect this
port directly to a laptop to view and locally manage the switch configurations.
Most models have two high-speed stacking ports that allow you to combine multiple units into a single
SummitStack management entity. On the 8-port models, the stacking ports are on the front panel. On
the 24 and 48 port 10-G models, the SFP+ 10G ports on the front panel can be used as alternate
stacking ports. On all other Summit X440 series switches (except the x440-L2-24t and x440-L2-48t
which do not have stacking capability), the stacking ports are on the back panel. Stacking port locations
are listed in the following table.
