Verifying A Successful Installation; Removing A Blackdiamond 6800 Series Power Supply - Extreme Networks Summit Summit1i Hardware Installation Manual

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 MSM performs a POST of its circuitry. The
LED labeled "SYS" on the MSM blinks amber during the POST. After the MSM 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
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 Ensure that the rack and chassis are grounded to protective earth ground.
For more information about grounding the rack, see "Protective Grounding for the Rack" on page 46.
For more information about grounding the chassis, see "Grounding the BlackDiamond 6800 Series
Chassis" on page 208.
3 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.
4 Unscrew the power supply using a #1 Phillips screwdriver.
