M7i Router Environmental Specifications

Table 18 on page 165 specifies the environmental conditions required for normal router

operation. In addition, the site should be as dust-free as possible. Dust can clog air intake

vents and filters, reducing cooling system efficiency. Check the filters and vents frequently,

cleaning them as necessary. For more information, see “Routine Maintenance Procedures

for the M7i Router” on page 73.
