CHAPTER 6: POWER SUPPLIES
6.2 AC POWER SUPPLY INSTALLATION
NOTE: The PSU slides into the slot smoothly. Do not force a PSU into a slot as this action may damage the PSU or the switch
chassis.
NOTE: Make sure that you correctly install the PSU. When you install the PSU correctly, the power connector is on the right side
of the PSU.
1. Remove the PSU slot cover from the switch using a small #1 Phillips screwdriver.
2. Remove the PSU from the electro-static bag.
3. Insert the PSU into the switch PSU slot. Insert the PSU exposed PCB edge connector first. The PSU slot is keyed so that the PSU
can only be fully inserted in one orientation.
When you install the PSU correctly, it snaps into place and is flush with the back of the switch.
FIGURE 6-2. PSU INSTALLATION
NOTE: In the figure above, the power supply is on the right side and the fan unit is on the left.
4. Plug in the appropriate AC three-prong power cord from the switch PSU to the external power source.
5. Repeat steps 1 through 4 above using the second PSU slot on the switch.
NOTE: The switch powers up when you connect the cables between the power supply and the power source.
