Site Environmental Requirements

Table 17 specifies the environmental conditions required for normal router operation. In addition, the site should be as dust-free as possible. Dust can clog the air filter, reducing cooling system efficiency. Check the air filter under the cable management system and the covers on all cooling subsystems frequently, cleaning them as necessary. For more information, see Maintain and Replace Cooling System Components.
