Summit X150 Series Switches - Extreme Networks Summit X450a-24tDC Hardware Installation Manual

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 XX250e-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 ExtremeXOS Concepts 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:
