Installing The Power Supply; Verifying A Successful Installation - Extreme Networks Summit 300-24 Hardware Installation Manual

Installing and Connecting BlackDiamond 6800 Series Power Supplies
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.

Installing the Power Supply

To install the 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 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 (Alpine and
BlackDiamond Switches)" on page 40. For more information about grounding the chassis, see
"Grounding the BlackDiamond 6800 Series Chassis" on page 238.
3 If a blank faceplate is covering the power supply bay, remove it and save it for future use.
4 Prepare the power supply for installation as follows:
a Support the power supply with both hands under the unit while you check the connectors for
dust and packing materials.
b Note the correct orientation of the power supply as noted in Figure 134 and Figure 135.
c Open the locking handle.
5 Carefully slide the power supply into the power supply bay.
CAUTION
Do not slam the power supply into the backplane. Use the locking handle to secure the power supply
unit into the chassis.
6 Push in on the locking handle until it clicks in place to secure the power supply.
7 Tighten the screws using a #1 Phillips screwdriver.
8 Connect the DC power cables as follows:
a Verify that the DC power is turned off at the source.
b Remove the plexiglass cover over the connection terminal block.
c Secure the connection lugs to the studs using the provided lock washers and nuts.
d Replace the plexiglass cover.
9 Turn on the DC power at the source
10 Turn the on/off switch to the on position.
Leave the ESD strap permanently connected to the chassis so that it is always available when you need
to handle ESD-sensitive components.
To install additional power supplies, repeat steps 3 through 10.

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.
