Before you begin, verify that:
• the equipment rack is securely installed, anchored, and grounded. Refer to the rack
manufacturer’s documentation for instructions.
• nearby equipment, including breaker panel bus bars and power connectors, is made
safe. Either shut off the power, if possible, or install safety guards or mats over
exposed power points and cables.
Required tools:
• a screwdriver appropriate for the rack-mount screws
For ETSI rack installations, replace the 19-inch rack-mount brackets with the ETSI
rack-mount brackets before installing the chassis. See Installing ETSI Rack-Mount Brackets.
