connection automatically fails over to the second connection. To set up a redundant link on a combination port, connect the active 1000BASE-T and fiber links to both the RJ-45 and SFP interfaces of that port.

Gigabit Ethernet uplink redundancy on the Summit family switches follows these rules:

●With both the SFP and 1000BASE-T interfaces connected on a combination port, only one interface can be activated. The other is inactive.

●If only one interface is connected, the switch activates the connected interface.

●The switch determines whether the port uses the fiber or copper connection based on the order in which the connectors are inserted into the switch. When the switch senses that an SFP and a copper connector are inserted, the switch enables the uplink redundancy feature. For example, if you first connect copper ports 25 and 26 on a Summit X250e-24t switch, and then insert SFPs into ports 25 and 26, the switch assigns the copper ports as active ports and the fiber ports as redundant ports.

Hardware determines when a link is lost and swaps the primary and redundant ports to maintain stability. After a failover occurs, the switch keeps the current port assignment until another failure occurs or a user changes the assignment using the CLI. For more information about configuring automatic failover on combination ports, see the Extre me XOS Conce pts Guide .

Summit X150 Series Switches

The Summit X150 series switches provide 24 or 48 fixed 10/100BASE-T Ethernet ports that deliver high-density copper connectivity for 2.4 Gbps or 4.8 Gbps. Models are available with PoE and without PoE. Each Summit X150 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. On the back of the switch, 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.

The rear panel of the switch provides an AC power input socket and a redundant power connector. The internal power supply operates from 100 VAC to 240 VAC. The switch automatically adjusts to the supply voltage. The redundant power connector allows you to connect the switch to the EPS-160 or EPS-500 external power supply. When a compatible external power supply is used with the Summit X150 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.

The Summit X150e series switches include the following switches:

●Summit X150-24t Switch

●Summit X150-24t-TAA Switch

●Summit X150-24p Switch

●Summit X150-24p-TAA Switch

●Summit X150-48t Switch

●Summit X150-48t-TAA Switch
