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.
