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 stack
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.

Note
The X440-L2-24t and the X440-L2-48t do not have stacking capability.
The rear panel provides an AC power input socket or DC input connector; 24-port and 48-port switch
models also include a redundant power connector. The switch automatically adjusts to the supply
voltage. The redundant power connector allows you to connect the switch to the EPS-C2 external
