BlackDiamond 6800 Series Switch Overview
BlackDiamond 6808 Switch
The BlackDiamond 6808 switch consists of the following components:
•
One 10-slot chassis with backplane
•
Eight I/O module slots, labeled slots 1 through 8
•
Two MSM64i slots, labeled slots A and B
•
Two power supply bays (accessed from the front of the unit)
•
One fan tray (accessed from the rear of the unit)
•
One electromagnetic discharge (ESD) wrist strap connector
BlackDiamond 6804 Switch
The BlackDiamond 6804 switch consists of the following components:
•
One 6-slot chassis with backplane
•
Four I/O module slots, labeled slots 1 through 4
•
Two MSM64i slots, labeled slots A and B
•
Two power supply bays (accessed from the front of the unit)
•
One fan tray (accessed from the front of the unit)
•
One electromagnetic discharge (ESD) wrist strap connector
BlackDiamond Power Supplies
Three types of power supplies are available for the BlackDiamond switches:
•
220 VAC
•
110 VAC
•
-48 VDC
All installed power supplies must be of the same type. You cannot mix 110 VAC, 220 VAC, and -48 VDC
power supplies in a single chassis.

All BlackDiamond power supplies are hot-swappable. They are also load-sharing. If one power supply
fails in a BlackDiamond 6800 series chassis, the remaining power supplies will provide sufficient power
to operate a chassis that has all slots populated with modules.

Switch Connectivity and the Backplane
Switch connectivity is an important aspect of the BlackDiamond 6800 series switch. The MSM64i
module is the internal switch fabric for data being sent between I/O modules. No configuration
information is stored on the I/O modules; all configuration information is stored on the MSM64i
module(s).

Each MSM64i has two CPUs for protocol processing and network management. For full redundancy,
you can install up to four MSM64i modules in the BlackDiamond 6816 switch and up to two MSM64i
modules in the BlackDiamond 6808 and BlackDiamond 6804 switches.

The BlackDiamond 6800 series switch has a 100% passive backplane which means the backplane does
not contain any active components that can fail. A passive backplane is important because it increases
