The Summit X250e series switches provide 24 or 48 Ethernet ports that deliver high-density fast Ethernet connectivity using fixed 10/100/1000BASE-T ports or installable small form pluggable (SFP) optical modules.
Fixed-port models are available either with or without PoE. Each Summit X250e series switch has two combination ports that provide 10/100/1000 BASE-T or SFP connectivity for 2 Gbps of copper or fiber connectivity. 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.
On the back of the switch, two high-speed stacking ports allow you to combine multiple units into a single SummitStack management entity. The rear panel also provides an AC or DC power input socket and a redundant power connector. (See specific switch descriptions for more information about the power options.) The switch automatically adjusts to the supply voltage. The redundant power connector allows you to connect the switch to the EPS-160, EPS-500, or EPS-150DC external power supply. When a compatible external power supply is used with the Summit X250e series switch, the internal and external power supplies are fully fault tolerant and load-sharing. If one power supply fails, the other power supply will provide sufficient power to operate the switch.
Note
In the descriptions that follow, references to a Summit X250e series model number also apply to the equivalent TAA-compliant switch version.Summit X250e series switches require an ExtremeXOS version of at least 12.0.1.11 but not greater than 15.3.x.
