Installing and Connecting BlackDiamond 6800 Series Power Supplies
Replacing a BlackDiamond 6800 Series AC Power Supply
BlackDiamond 6800 series power supplies are hot-swappable. You can add or remove power supplies
without turning off power to the chassis. 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 power supply
without turning off power to the chassis.
You need the following tools and equipment to replace a BlackDiamond 6800 series power supply:
• ESD-preventive wrist strap
• # 1 Phillips screwdriver
• Replacement power supply
To remove a 110 VAC or 220 VAC power supply:
1 Attach the ESD strap to your wrist and connect the metal end to the ground receptacle on the top
left corner of the switch front panel.
2 Verify that the rack and chassis are grounded to protective earth ground.
3 Disconnect the power supply cable(s) from the wall outlet and then from the power supply.
4 Unscrew the retaining screws using a #1 Phillips screwdriver.
5 Rotate the locking handle outward to disengage the power supply from the backplane.
