BlackDiamond 6800 Series Switch Overview
The rear of the BlackDiamond 6804 switch provides:
• Grounding studs
• System label that includes:
— Chassis serial number
— Ethernet MAC address of the switch
— Symbols of safety certification
BlackDiamond Power Supplies
Power supplies in the BlackDiamond switch are installed from the front of the chassis. BlackDiamond
power supplies are
iPower power supplies. Three types of power supplies are available:
• 220 VAC (200-240 VAC)
• 110 VAC (110-240 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 fully fault-tolerant, hot-swappable, and load-sharing. Depending
on the modules installed in the chassis:
• Four power supplies can support a fully loaded BlackDiamond 6816 chassis
• Two power supplies can support a fully loaded BlackDiamond 6808 chassis
• Two power supplies can support a fully loaded BlackDiamond 6804 chassis
To increase switch reliability, you can install additional power supplies as needed. If you have three or
more power supplies installed in a BlackDiamond 6816 switch or two or more power supplies installed
in a BlackDiamond 6808 or BlackDiamond 6804 switch, you can remove one of the power supplies
without turning off power to the chassis.
Table 45 lists the minimum number of power supplies required to power a BlackDiamond 6800 series
chassis.
NOTE
If you install four power supplies in a BlackDiamond 6816 chassis, the power supplies will deliver full
redundancy.
