Router Environmental Specifications

Table 19 on page 173 specifies the environmental specifications required for normal router operation. In addition, the site should be as dust-free as possible. Dust can clog air intake vents, reducing cooling system efficiency. Check the vents frequently, cleaning them as necessary. For more information, see “Maintaining Hardware Components” on page 73.
