Installation Guide

The copper port operates as an autonegotiating 10/100/1000BASE-T port. The optical port allows
Gigabit Ethernet uplink connections through Extreme Networks small form factor pluggable (SFP)
interface modules. See the individual switch descriptions for the port numbers of the combination ports
on each switch model.
ExtremeSwitching switches support automatic failover from an active fiber port to a copper backup or
from an active copper port to a fiber port. If one of the uplink connections fails, the Summit uplink
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 RJ45 and SFP interfaces
of that port.
Gigabit Ethernet uplink redundancy on the ExtremeSwitching 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 x and y on a switch, and then insert SFPs into ports x and y, the switch
assigns the copper ports as active ports and the fiber ports as redundant ports.
Hardware identifies when a link is lost and responds by swapping 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 16.2 User 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 at 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 sucient power to operate the switch.
The Summit X150e series switches include the following switch models:
• Summit X150-24t Switch Ports and Slots on page 27
• Summit X150-24t-TAA switch
• Summit X150-24p Switch Ports and Slots on page 28
