Summit X440 Series Switches

The Summit X440 series switches provide 8, 24, or 48 Ethernet ports that deliver high-density fast Ethernet or Gigabit Ethernet connectivity using fixed 10/100/1000BASE-T or 100/1000 BASE-X ports.

Additional ports on various models include the following:

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.
X440 Switch Type Stacking Port type Port Location
8p and 8t High-speed stacking port Front panel
24p, 24t, 24tDC, 24x, 48p, 48t, 48tDC High-speed stacking port Rear panel
24p-10G, 24t-10G, 24x-10G 48p-10G, 48t-10G SFP+ Front panel


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 power system. When a compatible external power supply is used with the Summit X440 series switch, the internal and external power supplies are fully fault tolerant. If one power supply fails, the other power supply will provide sufficient power to operate the switch.

Most Summit switches have fans that can change speeds depending upon operating conditions. See Summit X440 Series Switches Technical Specifications for specifications.

The minimum required ExtremeXOS version for Summit X440 series switches varies by model. (See the Extreme Hardware/Software Compatibility and Recommendation Matrices for details.) The ExtremeXOS version cannot be greater than 16.x.
