1BlackDiamond Overview
The BlackDiamond 6800 is a chassis-based system that is designed to be placed in the
core of your network. The BlackDiamond system is flexible and scalable, making it easy
for you to meet the changing requirements of your network. The combination of
BlackDiamond systems and Summit switches delivers a consistent end-to-end network
solution that provides non-blocking architecture, wire-speed switching, wire-speed IP
routing, and policy-based Quality of Service.W
This chapter describes the following:
•BlackDiamond 6800 components
•BlackDiamond 6800 features
•How to use the BlackDiamond 6800 system in your network configuration
•Factory default settings
BLACKDIAMOND 6800 COMPONENTS
The BlackDiamond 6800 system, shown in Figure 1-1, consists of the following
components:
•One 10-slot chassis with backplane
•Eight I/O module slots, labeled Slot 1 through Slot 8
•Two MSM module slots, labeled Slot A and Slot B
•As many as two load-sharing, fully redundant power supplies
•One hot-swappable fan tray (accessed from the rear of the unit)
