Connecting the AC Power Cord

Step1 Wear an ESD-preventive wrist strap, ensure a good skin contact and make sure that the ESD-preventive wrist strap is properly grounded.

Step2 Install the bail latch to prevent the AC power cord from accidentally falling off. Fix the bail latch into the holes located at the two sides of the AC power receptacle. Then pull the bail latch upwards (see in Figure 3-15 or Figure 3-17).

Step3 Connect one end of the AC power cord to the AC receptacle on the switch (see callout 1 in Figure 3-16 or Figure 3-18).

Step4 Pull the bail latch down to secure the plug to the AC receptacle (see callout 2 in Figure 3-16 or Figure 3-18).

Step5 Connect the other end of the AC power cord to the external AC power supply system.

Step6 Check whether the system status LED (PWR) on the front panel of the switch is ON. If the LED is ON, it shows the power cord is properly connected.
