Wiring the DC Power Supply
If you ordered a Cisco 2524 router with a DC power supply, follow the directions in this
section to wire the terminal block.
Warning Before performing any of the following procedures, ensure that power is
removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on
the panel board that services the DC circuit, switch the circuit breaker to the OFF position,
and tape the switch handle of the circuit breaker in the OFF position. (To see translated
versions of this warning, refer to the appendix “Translated Safety Warnings.”)
Note This product is intended for installation in restricted access areas and is approved for
use with copper conductors only. The installation must comply with all applicable codes.
Figure 3-14 shows the DC power supply terminal block. Take the following steps to wire
the terminal block:
Step 1 Attach the appropriate lugs at the wire end of the power supply cord.
Step 2 Wire the DC power supply to the terminal block, as shown in Figure 3-14.
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. (To see translated versions of this warning, refer to the appendix “Translated Safety
Warnings.”)
