Select channels from the range specified in your channel plan. Note Cisco recommends an uninterruptable power source to protect against power failures at your site. You can maintain normal operation by anticipating and correcting environmental anomalies before they approach a maximum operating range. The Cisco 6920 is cooled by conduction from the bottom through the top of the chassis. Keep the top and bottom of the chassis clear of obstructions and away from the exhaust of other equipment.
Equipment placed too close together or inadequately ventilated can cause systems to overheat.
In addition, chassis panels made inaccessible by poor equipment placement can make system maintenance difficult. Following are precautions that can help avoid problems during installation and ongoing operation. Follow ESD prevention procedures to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure. Install a new power conditioner if necessary.
