Tools and Parts Required

To remove components from the chassis or the chassis from a rack, you need the following tools and parts:

• 2.5-mm Phillips (+) screwdriver, for detaching alarm relay contact wires
• Mechanical lift, if available
• Phillips (+) screwdrivers, numbers 1 and 2
• 7/16-in. hexagonal-head external drive socket wrench, or nut driver, with a torque range between 23 lb-in. (2.6 Nm) and 25 lb-in. (2.8 Nm), for loosening nuts to terminal studs on the circuit breaker box on a DC-powered router

  Caution: Do not substitute a metric nut driver or wrench. A tool that does not fit the nuts exactly can damage them.
