M40e Router Environmental Specifications
Table 1 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 M40e Router.
