Weight support
Evaluate the floor loading as compared to the actual weight of the switch and its accessories, and make
sure that the floor can support the weight of the cabinet and the switch chassis.
Temperature/humidity
Maintain appropriate temperature and humidity in the equipment room.

change of materials, and metal corrosion.
• Lasting low relative humidity can cause washer contraction and ESD and bring problems including
loose captive screws and circuit failure.
