• Touch only the edges, instead of electronic components when observing or moving a removed
memory module, CF card, or HIM/MIM.
To use the ESD-preventive wrist strap, perform the following steps:
Step1 Wear the wrist strap on your wrist.
Step2 Lock the wrist strap tight around your wrist to keep good contact with the skin.
Step3 Insert the ESD-preventive wrist strap into the specially designed hole on the router chassis or attach it to
the grounding screw of the chassis with the alligator clips.
Step4 Make sure that the rack is well grounded.

CAUTION:
•
Check the resistance of the ESD-preventive wrist strap for safety. The resistance reading should be in the
range of 1 to 10 megohm (Mohm) between human body and the ground.
• No ESD-preventive wrist strap is provided with the H3C SR6602 router. Prepare it yourself.
EMI
All electromagnetic interference (EMI) sources, from outside or inside of the router and application system,
adversely affect the router in a conduction pattern of capacitance coupling, inductance coupling,
electromagnetic wave radiation, or common impedance (including grounding system) coupling. To
prevent EMI, perform the following steps:
• Take measures against interference from the power grid.
• Do not use the router together with the grounding equipment or light-prevention equipment of
power equipment, and keep the router far away from them.
• Keep the router far away from high-power radio launchers, radars, and equipment with high
frequency or high current.
