Before you connect earth ground to the protective earthing terminal of a ACX6160 device, ensure that a licensed electrician
has attached an appropriate grounding lug to the grounding cable.
CAUTION: Using a grounding cable with an incorrectly attached lug can damage the device.
NOTE: Mount your device in the rack before attaching the grounding lug to the device. See Mounting the ACX6160.
Ensure that you have the following parts and tools available:
•Grounding cable for your ACX6160 device—The grounding cable must be 14 AWG (2 mm²), minimum 90° C wire, or as
permitted by the local code. We have grounding points on either side or on one side of the chassis. These can be seen
through the gaps in the mounting rails/blades. We align the grounding lug with the grounding points on the chassis, and
then screw the lug in to the points.
•Grounding lug for your grounding cable—The grounding lug required is a Panduit LCD10-10A-L or equivalent.
•Two SAE 10-32 UNF x .31L washers and screws—To attach the grounding lug to the protective earthing terminal.
•Screwdriver to attach the screws.
To connect earth ground to a ACX6160 device:
1. Attach one end of the grounding cable to an appropriate earth ground site, such as the mounting rack.
2. Position the grounding lug attached to the grounding cable over the protective earthing terminal on the side of the
chassis. See Figure 5.

4. Dress the grounding cable and ensure that it does not touch or block access to other device components and that it
does not drape where people could trip over it.
Step 5: Connect to the Management Console
The ACX6160 has a console port with an RJ-45 connector. Use the console port to connect the device directly to a
management console, such as a laptop, or to a console server.
Ensure that you have an RJ-45 to DB-9 rollover cable available.
NOTE: If your laptop or PC does not have a DB-9 male connector pin and you want to connect your laptop or PC
directly to the ACX6160, use a combination of the RJ-45 cable and RJ-45 to DB-9 adapter and a USB to DB-9
male adapter. You must provide the cable and adapter.

Step 6: Power On the ACX6160
IN THIS SECTION
Connecting DC Power to the ACX6160 | 7
Connecting DC Power to the ACX6160
The ACX6160 is shipped from the factory with two power supplies. Each power supply is a hot-removable and hot-insertable
field-replaceable unit (FRU) when the second power supply is installed and running. You can install replacement power
supplies in the two slots next to the fan modules without powering off the device or disrupting the routing functions.
WARNING: DC-powered ACX6160 models are intended for installation only in a restricted-access
location.
NOTE: The battery returns of the DC power supply must be connected as an isolated DC return (DC-I).
Ensure that you have the following parts and tools available:
•ESD grounding strap
•DC power source cables (14–16 AWG) with ring lug (Molex 190700069 or equivalent) (not provided)
7

•Phillips (+) screwdriver, number 2 (not provided)
•Multimeter (not provided)
Before you begin connecting DC power to the ACX6160:
•Read General Electrical Safety Guidelines and Warnings,DC Power Electrical Safety Guidelines, and the following warnings:
•DC Power Copper Conductors Warning
•DC Power Disconnection Warning
•DC Power Grounding Requirements and Warning
•DC Power Wiring Sequence Warning
•DC Power Wiring Terminations Warning
•Ensure that you have taken the necessary precautions to prevent ESD damage (see Prevention of Electrostatic Discharge
Damage).
•Ensure that you have connected the ACX6160 chassis to earth ground.
CAUTION: Before you connect power to the device, a licensed electrician must attach a cable lug to
the grounding and power cables that you supply. A cable with an incorrectly attached lug can damage
the device (for example, by causing a short circuit). To meet safety and electromagnetic interference
(EMI) requirements and to ensure proper operation, you must connect the chassis to earth ground
before you connect it to power. For installations that require a separate grounding conductor to the
chassis, use the protective earthing terminal on the device chassis to connect to the earth ground. For
instructions on connecting earth ground, see Connecting the ACX6160 Grounding Cable.
•Install the power supply in the chassis following the instructions in Installing a Power Supply in an ACX6160 see the
ACX6160 Universal Metro Router Hardware Guide.
NOTE: Each power supply must be connected to a dedicated power source outlet.
To connect DC power to an ACX6160:
1. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other end of the strap
to an approved site ESD point on the chassis.
2. Verify that the DC power cables are correctly labeled before making connections to the power supply. 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 (+) and is installed on the
V+ (return) DC power input terminal.
•The cable with very high resistance (indicating an open circuit) to chassis ground is negative (–) and is installed on
the V– (input) DC power input terminal.
8

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.
3. 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.
NOTE: The V+ terminals are referred to as +RTN, and V– terminals are referred to as –48 V in DC Power Wiring
Sequence Warning and DC Power Electrical Safety Guidelines.
4. Ensure that the power supplies are fully inserted in the chassis.
5. Remove the terminal block cover. The terminal block cover is a piece of clear plastic that snaps into place over the
terminal block (see Figure 8).
6. Remove the screws on the terminals 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 on them.
7. Connect each power supply to the power sources. Secure power source cables to the power supplies by screwing the
ring lugs attached to the cables to the appropriate terminals by using the screw from the terminals (see Figure 8 and
Figure 9). The ACX6160 is designed to operate with a DC power supply that has a single, nonredundant, feed input.
For source redundancy, two DC power supplies must be installed; connect source (A) to one power supply and connect
source (B) to the second power supply. This configuration provides the commonly deployed A/B feed redundancy for
the system.
The terminal block of the power supply has four terminals labeled V+, V+, V–, and V– for connecting DC power source
cables labeled positive (+) and negative (–). The V+ terminals are shunted internally together, as are the V– terminals.
CAUTION: The connection between each power source and power supply must include a circuit
breaker.
Do not connect two sources to a single power supply because doing so can potentially cause circulating
current in feed wires whenever there is any difference in the voltage of the two sources.
a. Secure the ring lug of the positive (+) DC power source cable to the V+ terminal on the DC power supply.
9

b. Secure the ring lug of the negative (–) DC power source cable to the V– terminal on the DC power supply.
c. Use the screwdriver to tighten the screws on the power supply terminals until they are snug. Do not
overtighten—apply between 5 lb-in. (0.56 Nm) and 6 lb-in. (0.68 Nm) of torque to the screws.
