This chapter describes:
• Installing a BlackDiamond 6800 Series Power Supply on page 215
• Removing a BlackDiamond 6800 Series Power Supply on page 221
NOTE
Read the information in this chapter thoroughly before you attempt to install, remove, or supply power to
any BlackDiamond power supply.
BlackDiamond power supplies are iPower power supplies. Three types of power supplies are available:
• 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 fully fault-tolerant, hot-swappable, and they are load-sharing.
Depending upon the modules installed in the chassis, two power supplies can support a fully loaded
BlackDiamond 6816 chassis, and one power supply can support a fully loaded BlackDiamond 6808 or
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 56 lists the minimum number of power supplies required to power up a BlackDiamond 6800
series chassis.
