M7i Router Environmental Specifications
Table 44 on page 78 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 189.
