Caution:
Hold the handles on both sides of the chassis, instead of power handles or the vent of
the chassis when moving the switch. Since the power handle or the vent is not
designed to bear the weight of the entire chassis, the switch may get damaged or even
your body may get hurt if you hold these parts to move the switch.
2.1.4 Anti-static Safety
To prevent the electric component from being damaged by the electrostatic discharge
(ESD), take ESD measures for the area where the switch is located and note the points
below:
z
Always wear an ESD-preventive wrist strap when installing the parts, especially
the electric printed circuit boards, of the switch.
z
Take the edge of the circuit board. Do not touch the components or the electric
printed circuit.
Take the following steps to use the ESD-preventive wrist strap.
Step 1: Wear the ESD-preventive wrist strap.
Step 2: Strain and tighten the strap, and ensure that it makes good contact with your
skin.
Step 3: Insert the grounding terminal of the ESD-preventive wrist strap into the jack on
the switch chassis or attach it to the grounding screw of the chassis with an alligator
clip.
Step 4: Make sure the ESD-preventive wrist strap is well grounded.
Note:
An ESD-preventive wrist strap is shipped with the S7500E series.
There is a jack for the ESD-preventive wrist strap on the chassis of the S7500E series.
Caution:
For safety case, check the resistance of the ESD-preventive wrist strap. The resistance
between human body and the ground should be 1 to 10M ohm.
