3Examining the installation siteThe device can only be used indoors. To ensure correct operation and a long lifespan for your device,the installation site must meet the following requirements.Weight supportMake sure the floor can support the total weight of the rack, chassis, modules, and all othercomponents. For weights of the chassis and components, see "Appendix A Chassis views andtechnical specifications."Temperature and humidityMaintain temperature and humidity in the equipment room at levels as described in Table 2.• Lasting high relative humidity can cause poor insulation, electricity leakage, mechanicalproperty change of materials, and metal corrosion.• Lasting low relative humidity can cause washer contraction and ESD and bring problemsincluding loose captive screws and circuit failure.• High temperature can accelerate the aging of insulation materials and significantly lower thereliability and lifespan of the device.Table 2 Temperature and humidity requirementsItem SpecificationTemperature • Operating: 0°C to 45°C (32°F to 113°F)• Storage: –40°C to +70°C (–40°F to +158°F)Relative humidity 5% RH to 95% RH, noncondensingCleanlinessDust buildup on the chassis might result in electrostatic adsorption, which causes poor contact ofmetal components and contact points, especially when indoor relative humidity is low. In the worstcase, electrostatic adsorption can cause communication failure.Table 3 Dust concentration limit in the equipment roomSubstance Concentration limit (particles/m3)Dust particles ≤ 3 × 104(No visible dust on desk in three days)NOTE:Dust particle diameter ≥ 5 μmThe equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosionand premature aging of components, as shown in Table 4.Table 4 Harmful gas limits in an equipment roomGas Max.
