Site Environment

Table 2-1lists the operating and nonoperating environmental site requirements. The following ranges are those within which the Cisco uBR904 cable modem will continue to operate; however, a measurement that is approaching the minimum or maximum of a range indicates a potential problem. You can maintain normal operation by anticipating and correcting environmental anomalies before they approach a maximum operating range.

Operating temperature range: 32° though 114°F (0° through 40°C).

Operating humidity range: 5 to 95%, noncondensing.

Airflow: Keep the back, sides, and bottom of the Cisco uBR904 cable modem clear of obstructions and away from the exhaust of other equipment.

Caution To prevent chassis overheating, never install the Cisco uBR904 cable modem in an enclosed rack or room that is not properly ventilated or air conditioned.
