BlackDiamond 6800 Series Switch Power Supplies
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 for more information about switch management module
LED activity and Chapter 16 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, you can remove one of them
without turning off power to the chassis.
Three types of power supplies are available: 110 VAC, 220 VAC, and -48 VDC. All
installed power supplies must be of the same type.
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 cord(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.
