Summit Switch Models
Summit 300 Features
The Summit 300 series switch supports wireless and Power over Ethernet (PoE) networks. These
switches provide 24 or 48 autosensing 10BASE-T/100BASE-TX ports using RJ-45 connectors.
The Summit 300 series switches also provide either two or four uplink ports implemented as
combination ports that pair a copper port using RJ-45 connectors with an optical port using LC
connectors. The copper port operates as an autonegotiating 10/100/1000BASE-T port. The optical port
allows Gigabit Ethernet uplink connections through Extreme small form factor pluggable (SFP) gigabit
interface connectors (GBICs), also known as mini-GBICs. Only one port in the combination pair can be
used at one time. These combination ports are described further in “Summit 300 Automatic Failover” on
page 74.
Three types of mini-GBICS are available: 1000BASE-SX, 1000BASE-LX, or 1000BASE-ZX. Mini-GBICs are
purchased separately. For more information, contact your Extreme Networks Sales Representative.
The Summit 300 series switches support Power over Ethernet (PoE) as defined by the IEEE 802.3af
specification. PoE is an effective method of supplying 48 VDC power to certain types of powered
devices by way of Category 5 or Category 3 twisted pair Ethernet cables. Supported devices include the
Altitude 300 wireless port, IP telephones, laptop computers, web cameras, or other devices. With PoE, a
single Ethernet cable supplies power and the data connection, thereby saving time and expense
associated with separate power cabling and supply.
Hardware Features
The Summit 300 switch has the following features:
• Gigabit Ethernet uplinks, fiber/UTP redundant
— 2 uplink ports on the Summit 300-24
— 4 uplink ports on the Summit 300-48
• 10/100 Ethernet ports
— 24 ports on the Summit 300-24
— 48 ports on the Summit 300-48
• Serial management port
• Autoranging power supply that automatically adjusts to the AC supply voltage
• Optional redundant power supplies
— Rack-mountable External Power Supply 45019 (EPS-LD) for the Summit 300-24
— Hot-swappable internal redundant power supply for the Summit 300-48
• Modular expansion slot on the Summit 300-48 that supports various port configurations
Summit 300-24 Switch
The Summit 300-24 is 1U high and provides 24 autosensing 10BASE-T/100BASE-TX ports using RJ-45
connectors. The Summit 300-24 switch also provides two combination uplink ports implemented as
either 10/100/1000BASE-T ports using RJ-45 connectors or optical ports using mini-GBICs.
The Summit 300-24 switch can be interconnected with other Summit 300-24 switches or Summit 200
series switches to form a stacked configuration that is managed as a single switch entity. In a Summit
stacked configuration, the uplink ports provide interconnection between the stacked switches.
