Connecting Routers To The Cisco Redundant Power System - Cisco 2691 Quick Start Manual

Warning The illustration shows the DC power supply terminal block. Wire the DC power supply as illustrated. The proper
wiring sequence is ground to ground, positive to positive, and negative to negative. The ground wire should always
be connected first and disconnected last. Statement 239
Warning An exposed wire lead from a DC-input power source can conduct harmful levels of electricity. Be sure that no
exposed portion of the DC-input power source wire extends from the terminal block plug. Statement 122
Do not overtorque the terminal block contact screws. Recommended torque is 8.0 ± 0.5 in-lb (0.9 ± 0.05 N-m).
