1-2 Extreme Networks Consolidated Hardware Guide

Summary of Common Switch Features

Note: If the information in the Release Notes that shipped with your switch differs

from the information in this guide, follow the Release Notes.

Full-Duplex Support

Extreme Networks switches provide full-duplex support for all ports. This means that

frames can be transmitted and received simultaneously, which, in effect, doubles the

bandwidth available that is available on a link. Most ports on an Extreme Networks

switch autonegotiate for half-duplex or full-duplex operation. Gigabit Ethernet and

100BASE-FX ports operate in full-duplex mode only in accordance with technical

standards.

Management Ports

The 10/100BASE-TX Ethernet management port allows you to communicate directly to

the CPU of the switch. You can plug an Ethernet cable directly from your laptop into

the management port. This provides you with direct access into the switch and allows

you to view and locally manage the switch configurations.

The management port is located on the following Extreme Networks devices:

• Summit5i—The management port is located on the back side of the switch

• Summit7i —The management port is located on the front side of the switch

• Alpine—Switch Management Module (SMMi) for the Alpine series switch

• BlackDiamond—Management Switch Fabric Module (MSM64i) for the

BlackDiamond series switch
