Tools for Installation Chapter 2 Preparing for Installation General Precautions Follow these general precautions when planning your equipment locations and connections: • Use the show environment command regularly to check the internal system status. The environmental monitor continually checks the interior chassis environment; it provides warnings for high temperature and maximum and minimum voltages and creates reports on any occurrences. If warning messages are displayed, take immediate action to identify the cause and correct the problem. • We recommend keeping the Cisco 7206 off the floor and out of any area that tends to collect dust. • Follow ESD prevention procedures to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure. • Ensure that the network processing engine, I/O controller, port adapters, any blank port adapters, power supplies, and any power supply filler plates are in place and secure. The fans direct cooling air throughout the chassis interior; a loose component or empty slot can redirect the airflow away from active components. Power Considerations Follow these precautions and recommendations when planning power connections to the Cisco 7206: • Check the power at your site before installation and periodically after installation to ensure that you are receiving clean power. Install a power conditioner if necessary. • Install proper grounding to avoid damage from lightning and power surges. Note The Cisco 7206 installation must comply with all applicable codes and is approved for use with copper conductors only. The ground bond fastening hardware should be of compatible material and preclude loosening, deterioration, and electrochemical corrosion of hardware and joined material. Attachment of the chassis ground to a central office or other interior ground system should be made with a 6-AWG, copper ground conductor at a minimum. The Cisco 7206 chassis employs two threaded M5 chassis grounding receptacles, located on the rear of the chassis, which are intended to be bonded directly to the central offices or other interior ground system. The chassis ground requires M5 screws and locking hardware, which are not included. (For instructions on how to properly ground the chassis, refer to Chapter 3, "Installing the Cisco 7206," the "Providing a Chassis Ground Connection for the Router Chassis" section on page 3-12.) Tools for Installation Your Cisco 7206 chassis is fully assembled at the factory; no assembly is required. However, you will need the following tools and equipment to install the chassis and the rack-mount and cable-management kit: • Number 2 Phillips screwdriver • A 3/16-inch flat-blade screwdriver • Tape measure (optional) • Level (optional) Cisco 7206 Installation and Configuration Guide 2-8 OL-5102-02
