For information about the I/O modules and management modules (MSMs) for the BlackDiamond 12800 
series switches, see 

For information about installing the BlackDiamond switches, see 

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 

●

BlackDiamond 12802 chassis (see 

)

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.
