Replacing Connections to the Router

Step 5 Fasten the cover with the screws you set aside earlier.

Step 6 Reinstall the chassis on a rack, wall, desktop, or table.

Step 7 Reinstall network interface cables.

Replacing Connections to the Router

Note The installation must comply with the 1996 National Electric Code (NEC) and other

applicable codes.

Follow these steps to make ﬁnal connections to the router:

Step 1 Replace all network connections.

Step 2 If you have an AC-powered router, plug the power cord into a 3-terminal, single-phase

power source that provides power within the acceptable range (100 to 240 VAC, 50 to

60 Hz).

If you have a DC-powered router, rewire the DC-input power supply (38 to 72 VDC) to

the terminal block using 14 AWG copper wires. The proper wiring sequence is ground to

ground, positive to positive, and negative to negative. (See Figure 8.)

Warning Read the installation instructions before you connect the system to its power

source.

Warning This product relies on the building’s installation for short-circuit (overcurrent)

protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S.

(240 VAC, 10A international) is used on the phase conductors (all current-carrying

conductors).

Warning When stranded wiring is required, use approved wiring terminations, such as

closed-loop or spade-type with upturned lugs. These terminations should be the

appropriate size for the wires and should clamp both the insulation and conductor.

Warning The illustration shows the DC power supply terminal block. Wire the DC

power supply using the appropriate lugs at the wiring end, as illustrated. The proper

wiring sequence is ground to ground, positive to positive (line to L), and negative to

negative (neutral to N). Note that the ground wire should always be connected ﬁrst and

disconnected last.

Caution Do not overtorque the terminal block captive thumbscrew or terminal block

contact screws. The recommended torque is 8.2 ± 0.4 inch-lb.

Warning After wiring the DC power supply, remove the tape from the circuit breaker

switch handle and reinstate power by moving the handle of the circuit breaker to the ON

position
