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.
