For information about the I/O modules and management modules (MSMs) for the BlackDiamond 12800
series switches, see Chapter 3, “BlackDiamond 12800 Series Modules.”
For information about installing the BlackDiamond switches, see Chapter 2, “Installing the
BlackDiamond 12800 Series Chassis.”
Overview of the BlackDiamond 12800 Series Switches
The BlackDiamond switches are chassis-based, Ethernet service core switches designed for core
applications. For more information about configuring a BlackDiamond switch, see the ExtremeXOS 12.0
Concepts Guide and the ExtremeXOS 12.0 Command Reference Guide.
The features of these switches include:
● I/O modules that are hot-swappable and include Gigabit Ethernet copper ports (10/100/1000) and
Gigabit Ethernet fiber ports (SFP), or 10 Gigabit Ethernet ports
● Management Switch Fabric Modules (MSMs) that provide the active switching fabric and CPU
control subsystem
● Redundant, load-sharing, hot-swappable power supplies
● Field-replaceable, hot-swappable fan trays
● Auto-negotiation for half-duplex or full-duplex operation on 10/100/1000 Mbps ports
● Load sharing on multiple ports
The BlackDiamond 12800 series switches include two chassis models:
● BlackDiamond 12804 switch chassis (see page 16)
● BlackDiamond 12802 chassis (see page 18)
Full-Duplex Support
Extreme Networks switches provide full-duplex support for all ports. Full-duplex support means that
frames can be transmitted and received simultaneously, which, in effect, doubles the bandwidth
available on a link. Most ports on an Extreme Networks switch will auto-negotiate duplex in the default
configuration. Gigabit Ethernet fiber ports and 10 Gigabit Ethernet ports operate only in full-duplex
mode in accordance with technical standards.
