Installing Internal Power Supplies
If your switch does not come with an installed internal power supply, you can install one or two power
supplies.
The SLX 9150 and SLX 9250 Series switches supports 750 W power supply units using either AC or DC
power.
Follow the instructions in the following sections to install the appropriate power supply and connect
power to the switch.

Installing a 750 W Internal AC Power Supply
To install a 750 W AC power supply in a switch, follow these instructions.
All installed power supplies must have the same airflow direction (front-to-back or back-to-front) and
must match the airflow direction of the installed fan modules.
Warning
To prevent an electrical hazard, make sure that the AC power cord is not connected to the
power supply before you install the power supply in the power supply bay.
Warning
Make sure that the AC power supply circuit is not overloaded. Use proper over-current
protection, such as a circuit-breaker, to prevent over-current conditions.
1. If necessary, remove a blank panel from the back of the switch.
2. Verify that the new power supply is right side up.
3. Verify that the new power supply's airflow direction (front-to-back or back-to-front) is compatible
with the other installed power supply (if any) and with the installed fan modules.
