the DC source to the router. · A customer-site 2-pole circuit breaker rated for 30A and 80V, or as required by local electrical code.
Rack It
Before you start the installation, be sure to review the General Safety Guidelines and Warnings. Here’s how to install the ACX7024 in a two-post rack:

Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap
to a site ESD point. 2. Position the router in front of the rack.
The mounting brackets are preinstalled on the ACX7024 router. 3. Lift the ACX7024 router and position it in the rack. Line up the bottom hole in each mounting bracket with a hole in
each rack rail, making sure the ACX7024 router is level.
4. Secure the chassis to the rack using the rack mount screws (not provided). Tighten the screws on the bottom first, then tighten the screws on the top.
5. Check to see that the mounting screws on each side of the rack are lined up and the router is level.

Power On
Now that you’ve installed your ACX7024 in the rack, let’s connect it to power. The ACX7024 supports DC power supplies that are pre-installed at the factory.
CAUTION: The connection between each power source and power supply module must include a circuit breaker. We recommend that you use a customer-site 2-pole circuit breaker rated for 30A and 80V, or as required by local electrical code. Do not connect two sources to a single power supply module because doing so can potentially cause circulating current in feed wires whenever there is any difference in the voltage of the two sources. The ACX7024 router operates with a DC power supply module that has a single, non-redundant, feed input. For source redundancy, you’ll need to install two DC power supplies in the ACX7024. Connect source (A) to one power supply module and source (B) to the second power supply module. This configuration provides the commonly deployed A/B feed redundancy for the system. To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you’ll need to properly ground the router before connecting it to power. Have a licensed electrician attach the cable lug to the grounding cable. 1. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap to a site ESD point. 2. Connect the grounding cable to a proper earth ground. 3. Place the grounding cable lug over the grounding points on the side of the chassis, and secure it with the grounding screws. Apply 2.5 N-m of torque to the grounding screws.

5
4. Dress the grounding cable and verify that it doesn’t touch or block access to router components, or drape where people could trip over it.
5. Ensure that the power supplies are fully inserted in the chassis. 6. Verify that the DC power cables are correctly labeled before making connections to the power supply module. In a
typical power distribution scheme where the return is connected to chassis ground at the battery plant, you can use a multimeter to verify the resistance of the 48V and RTN DC cables to chassis ground: · The cable with very low resistance (indicating a closed circuit) to chassis ground is positive (+). You install this
cable on the V+ (return) DC power input terminal. · The cable with very high resistance (indicating an open circuit) to chassis ground is negative (). You install this
cable on the V (input) DC power input terminal.
CAUTION: You must ensure that power connections maintain the proper polarity. The power source cables might be labeled (+) and () to indicate their polarity. There is no standard color coding for DC power cables. The color coding used by the external DC power source at your site determines the color coding for the leads on the power cables that attach to the DC power input terminals on each power supply module. 7. Ensure that the input circuit breaker is open so that the voltage across the DC power source cable leads is 0 V and that the cable leads do not become active while you are connecting DC power. 8. Remove the terminal block cover. 9. Remove the screws on the terminals by using the screwdriver. Save the screws.
WARNING: Ensure that the power cables do not block access to device components or drape where people can trip over them. 10. Connect each power supply module to the DC power sources:

6 NOTE: To connect the DC source to an ACX7024 router, use a 12 AWG and 75°C temperature-rated or 14 AWG and 90°C temperature-rated stranded copper wire. To connect the DC power source to an ACX7024 in a data center or a central office, use a 14 AWG DC wire. a. Secure the ring lug of the positive (+) DC power source cable to the RTN (return) terminal on the DC power supply module using one of the terminal screws. b. Secure the ring lug of the negative () DC power source cable to the 48V (input) terminal on the DC power supply module using the other terminal screw. c. Tighten the screws on the power supply module terminals until snug using the Phillips number 2 screwdriver. Do not overtighten–apply 1.2 N-m of torque to the screws.
NOTE: After the input DC wires are crimped to the wiring lugs, cover the lugs and crimped area with a suitable heat shrink sleeve to avoid exposed bare lug or crimped areas. 11. Replace the terminal block cover. Apply 0.5 N-m of torque to the screws. 12. Close the input circuit breaker. NOTE: The switch powers on as soon as you connect it to power.
