2-2Table 2-1 is only for reference. If you install the AP on a desk, none of the above tools is required; if youinstall the AP on top of or under eave of a building, no digging tool is required.Examining the Installation SiteBefore installation, you should examine the installation site to keep the AP under a good operationalenvironment. You can examine the installation site from the following two aspects:Installation Site SelectionKeep the AP away from places that are susceptible to high temperature, dust, inflammable, explosive,electromagnetic interference (high power radar, radio station, and transformer), unstable voltage, heavyvibration, or loud noise. The installation site should be dry, without any leakage, dripping, or dew .TheAP should be at least 500 m (0.31 mi) away from the seaside and should not face the direction of seawind.In engineering design, the site should be selected according to the network planning and technicalrequirements of communications equipment, as well as the considerations such as climate, hydrology,geology, earthquake, electric power, and transportation.Temperature and Humidity RequirementsTable 2-2 lists the operating temperature and humidity requirements.Table 2-2 Environment specificationsSpecification RangeOperating temperature (indoor) -10°C to 55°C (14°F to 131°F)Operating temperature (outdoor) –40°C to +65°C (–40°F to +149°F)Storage temperature (indoor) –40°C to +70°C (–40°F to +158°F)Storage temperature (outdoor) –40°C to +85°C (–40°F to +185°F)Operating humidity (noncondensing) 5% to 95%Power SupplyThe WA2200 series can be powered through 802.3af-compliant power over Ethernet (PoE) (exceptWA2220X-AG) or an external power adaptor. For details see the Table 2-3.Outside China it is recommended that this unit be PoE powered. Please see the H3C/3Com productcatalogues for a range of 802.3af compatible power sources.
