(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 was 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
To remove a 110 VAC, 220 VAC, or -48 VDC power supply:
1 Attach the ESD strap that is provided to your wrist and connect the metal end to the ground
receptacle that is located on the top-left corner of the switch front panel.
2 Completely remove the power supply cable(s) from the wall outlet and then from the power supply.
If you have a DC power supply, turn the on/off switch to the off position and remove the power
cables.
3 Unscrew the power supply using a #1 Phillips screwdriver.
4 On a BlackDiamond 6816, disengage the power supply by rotating the handle out and to the left, as
shown in Figure 110.
On a BlackDiamond 6808 or BlackDiamond 6804, disengage the power supply by rotating the handle
out and down, as shown in Figure 111.
