Step 7: Apply AC Power and Check the LEDs
The switch does not provide an on/off switch. The power cord connection controls the power.
Before connecting the power cord, select an AC outlet that is not controlled by a wall switch, 
which can turn off power to the switch.
To apply AC power:
1. 
Connect the end of the power cord to the power receptacle on the power supply unit 
(PSU) on back of the switch.
2. 
Plug the AC power cord into a power source such as a wall socket or power strip.
When you apply power, the Power LED on the switch front panel lights. If your the switch 
provides a second power module bay in which no PSU is installed, the Power 1 LED on 
the front panel lights.
If the Power LED (or Power 1 LED) does not light, check that the power cord is plugged in 
correctly and that the power source is good.
Optional Step 8: Install a Second Power Supply Unit
This procedure is optional. The following full-width models provide a second power module 
bay in which you can install an optional second power supply unit (PSU):
M4300-24X24F and M4300-48X
