Connecting the AC Power Cord
To connect an AC power cord, follow these steps:
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 3-21 or Figure 3-23).
Step3 Connect one end of the AC power cord to the AC receptacle on the switch (see callout 1 in
Figure 3-22
or
Figure 3-24).
Step4 Pull the bail latch down to secure the plug to the AC receptacle (see callout 2 in
Figure 3-22 or Figure
3-24).
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/SYS) on the front panel of the switch is ON. If the LED is
ON, it shows the power cord is properly connected.
