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.
