Each set of power terminals on the DC power supply consists of two 6-mm, metric-threaded,
nickel-plated, brass studs centered 0.625 inch apart. The earth ground studs extend 0.52 inch (13.2 mm)
above the power supply faceplate; the set of positive (+) and negative (–) studs extend 0.9 inch
(22.9 mm) above the faceplate. The nickel plating on the studs enhances conductivity and resists
corrosion.
For convenience, the lock washers and nuts for connecting the source DC cables to the power terminals
are loosely mounted on the studs ready for use.

Verifying a Successful Installation

After you supply power to the BlackDiamond switch, each MSM64i performs a POST of its circuitry.
The LED labeled "SYS" on the MSM64i blinks amber during the POST. After the MSM64i has passed its
POST and is operational, each I/O module performs its own POST.
NOTE
See Chapter 15, "BlackDiamond 6800 Series Management Switch Module" for more information about
switch management module LED activity and Chapter 16, "BlackDiamond 6800 Series I/O Modules" for
more information about I/O module LED activity.
Removing a BlackDiamond 6800 Series Power Supply
BlackDiamond 6800 series power supplies are hot-swappable. You can add or remove power supplies
without turning off power to the chassis and normal operation will continue as long as the switch has
enough power to support the installed modules.
If you have three or more power supplies installed in a BlackDiamond 6818 or two or more power
supplies installed in a BlackDiamond 6808 or BlackDiamond 6804, you can remove one of them without
turning off power to the chassis.
You need the following tools and equipment to remove the BlackDiamond 6800 series power supplies:
• ESD-preventive wrist strap
• # 1 Phillips screwdriver
• Replacement power supply
