- Connect the Shared Port Adapter Cables
- Install the Cables Using the Cable-Management Brackets
Console Port Cable and Auxiliary Port Cable Connections
This section describes how to attach a cable to the console port or auxiliary port on the Cisco ASR 1002 Router. The Cisco ASR 1002 Router has two RJ-45 ports for terminal connection. A console port, which can be utilized for terminal connections and an auxiliary port for additional terminal connections as well as diagnostic utilization.
Caution Both the console port and the auxiliary port are asynchronous serial ports; devices connected to these ports must be capable of asynchronous transmission. To meet Class A emission requirements on the Cisco ASR 1002 Router, shielded cables must be used for the console port and auxiliary port connections.Perform the following steps to connect the console port cable and auxiliary port cable.
Step 1 Before connecting a terminal to the console port, configure the terminal to match the router console port as follows: 9600 baud, 8 data bits, no parity, 1 stop bit. See Figure 9 for the console port and auxiliary port connector location.
Figure 9 Cisco ASR 1002 Integrated Route Processor Console port and Auxiliary Port Connectors
Step 2 Connect to the port using the RJ-45-to-DB-9 cable.
Step 3 After you establish normal router operation, you can disconnect the terminal.
Note For information about console port and auxiliary port pinouts, see the Cisco ASR 1002 Router specifications in the Cisco ASR 1000 Series Aggregation Services Routers Hardware Installation Guide.
Connect the Ethernet Management Port
To use the Management Ethernet interface on the router, perform the following steps:

Step 5 Insert the stripped end of the ground lead all the way into the ground lead receptacle on the –48V DC-input power supply, and tighten the receptacle screw using a 3.5 mm flat-blade screwdriver to a torque of 0.5 to 0.6Nm.
Step 6 Insert the stripped end of the positive lead all the way into the positive lead receptacle and tighten the receptacle screw using the same 3.5 mm flat-blade screwdriver. Repeat this step for the negative lead.
Note Make sure the entire stripped end of each lead is inserted all the way into its receptacle. If any exposed wire at the stripped end of a lead is visible after inserting the lead into its receptacle, remove the lead from the receptacle, use the wire stripper to cut the stripped end of the lead, and repeat Step 4 through Step 6.
Step 7 After tightening the receptacle screw for the ground, positive, and negative DC-input leads, use a cable tie to secure the three leads to the power supply faceplate.
Note When securing the ground, positive, and negative DC-input leads to the power supply faceplate, leave extra service loop in the ground lead to ensure that the ground lead is the last lead to disconnect from the power supply if a great deal of strain is placed on all three leads.
Step 8 Turn the branch circuit breaker on at your site and the turn the Standby switch to the On (I) position.
Step 9 Check that the power supply LEDs light when power is supplied to the router.
You have completed the procedure for connecting a –48V DC power supply in the Cisco ASR 1002 Router.
Connecting +24V DC Power to the Cisco ASR 1002 Router
The +24V DC power supply uses a spring-loaded terminal block. The input terminal block requires 8 AWG multi-strand wiring to support input current. Features are provide for strain relieving the input wires from the terminal block on the front panel. The recommended branch circuit breaker for the Cisco ASR 1002 Router +24V DC power supply is a 40Amp UL listed circuit breaker.
Before you begin, read these important notices about the +24V DC power supply:
- The labeling displays +27V DC INPUT. This labeling describes the nominal voltage provided at a cell site.
- Observe the polarity location—Unlike the polarity labels of the –48V DC power supply (ground, positive, negative), the polarity labels on the +24V DC are ground, negative, positive as shown in Figure 19 from right to left as they appear on the actual power supply unit.
- The ground (GND) lead is always installed first and removed last.
- The +24V DC power supply uses a spring loaded terminal block; therefore have the recommended screwdriver size available.
- Review the diagrams to see how the wire is stripped and how the screwdriver is inserted at an angle into the terminal block.
- Have the following equipment available to install and remove the +24V DC power supply:
– Phoenix-Contact 3.5mm flat-blade screwdriver or equivalent
– Wire-stripping tool for stripping 8-gauge wire
Figure 19 Cisco ASR 1002 Router +24V DC Power Supply Components
Note The color coding of the +24V DC-input power supply leads depends on the color coding of the +24V DC power source at your site. Typically, green or green/yellow is used for ground. Make certain the lead color coding you choose for the +24V DC-input power supply matches lead color coding used at the +24V DC power source. Most commonly used wire color-coding is red for positive (+) lead and black for negative (–) lead.
Warning When you install the unit, the ground connection must always be made first and disconnected last. Statement 1046
To connect +24V DC power supply in the Cisco ASR 1002 Router, follow these steps:
Step 1 At the rear of the router, check that the power Standby switch is in the Standby position.
Step 2 Ensure that the positive and negative leads are disconnected from the site power source and the source circuit breaker is turned off.
Step 3 Using a wire stripper, strip the recommended amount of wire insulation which is 15mm (0.6 inch) from the ground, negative, and positive leads.
Note The stripping length is common to all types of wire used.
Figure 20 shows the wire lead and insulation area.
Figure 20 Cisco ASR 1002 Router +24V DC Power Supply Wire and Insulation
Note Make sure the stripped end of each lead wire is twisted tightly together. This makes insertion easier. Then make certain the entire lead wire is inserted all the way into its receptacle. If any exposed wire at the stripped end of a lead is visible after inserting the lead into its receptacle, remove the lead from the receptacle, use the wire stripper to cut the stripped end of the lead, and then reinsert.
Step 4 Using a 3.5mm screwdriver, insert the screwdriver at an angle to release the spring while you install the stripped lead wire (see Figure 21) .
Figure 21 Inserting a Screwdriver into the Cisco ASR 1002 Router +24V DC Power Supply Terminal Block

Figure 25 Cisco ASR 1002 Router +24V DC Power Supply Lead Wires Installed
Note The color coding of the DC-input power supply leads depends on the color coding of the DC power source at your site. Typically, green or green/yellow is used for ground (GND), black is used for –48V on negative (–) terminal and red is used for RTN on the positive (+) terminal. Make certain the lead color coding you choose for the DC-input power supply matches lead color coding used at the DC power source.
Step 10 After inserting the ground wire leave an extra service loop in the ground lead to ensure that the ground lead is the last lead to disconnect from the power supply if a great deal of strain is placed on all three leads. Use a cable tie wrap to secure the three leads to the power supply faceplate. There are tabs on the power supply to use for the tie wraps as shown in Figure 26 .
Figure 26 Cisco +24V DC Power Supply Terminal Block Ground Lead Service Loop
Caution When securing the ground, positive, and negative +24V DC-input leads to the power supply faceplate, leave extra service loop in the ground (GND) lead to ensure that the ground lead is the last lead wire to disconnect from the power supply if a great deal of strain is placed on all three leads.Step 11 After tightening the receptacle screw for the ground, and leaving the extra service loop in the ground lead, use a cable tie to secure the three leads to the power supply faceplate tie-wrap tab as shown in.
Step 12 Turn on the branch source breaker. The following LEDs light up: OUTPUT FAIL is red, INPUT OK should be green, and FAN OK is off.
Step 13 Place the power supply standby switch to the On (|) position. The power supply LEDs light when power is supplied to the router. The following LEDs light up: OUTPUT FAIL is off, INPUT OK is green, and FAN OK is green.
