Connecting the JRR200 to Power

Connect the Grounding Cable

Ensure that you have the following parts and tools available:

Electrostatic discharge (ESD) grounding wrist strap
Phillips (+) screwdriver, number 2
16 AWG single-strand wire grounding cable (green and yellow wire)
Grounding lug (ring-type, vinyl-insulated TV14-6R lug, or equivalent)
One metric M5 x 10 mm grounding screw

To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, the JRR200 Route Reflector must be adequately grounded before power is connected. You must provide a grounding lug to connect the route reflector to earth ground.

You ground the route reflector by connecting a grounding cable to earth ground and then attaching it to the chassis grounding point located on the back panel of the device using an M5 x 10 mm grounding screw.

CAUTION:

Before you connect power to the route reflector, a licensed electrician must attach a cable lug to the grounding cable that you supply. A cable with an incorrectly attached lug can damage the route reflector (for example, by causing a short circuit).

To connect the route reflector to earth ground:

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point. See the instructions for your site.
Connect one end of the grounding cable to a proper earth ground, such as the rack in which the JRR200 route reflector is mounted.
Place the grounding cable lug over the grounding point on the rear of the chassis.

Note:
The JRR200 route reflector should be permanently connected to ground during normal operation. A licensed electrician must attach a cable lug to the grounding cable. A cable with an incorrectly attached lug can damage the JRR200 route reflector.
Secure the grounding cable lug to the grounding point with the screw.
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.

Note:

When removing the chassis, turn off the power, and disconnect the grounding cable.

Connecting Power to an AC-Powered JRR200 Route Reflector

Ensure that you have a power cord appropriate for your geographical location available to connect AC power to the JRR200 Route Reflector. Before you begin connecting AC power:

Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage.
Ensure that you have connected the device chassis to earth ground.

CAUTION:
Before you connect power to the JRR200 route reflector, a licensed electrician must attach a cable lug to the grounding cable 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 properly ground the JRR200 route reflector chassis before connecting power.
Check that the power supplies are fully inserted into the chassis.

To connect AC power:

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the rear of the chassis.
Locate the power cords shipped with the JRR200 route reflector; the cords have plugs appropriate for your geographical location.
Set the power switch on the JRR200 route reflector to the off (O) position.
Insert the coupler end of the power cord into the AC power cord inlet on the AC power supply faceplate. Push the power cord retainer onto the power cord.

Note:
An AC-powered device gets additional grounding when you connect the power supply in the device to a grounded AC power outlet by using the power cord.
Insert the power cord plug into an AC power source outlet.
Repeat steps 4 and 5 for the second AC power supply.
Dress the power cord appropriately. Verify that the power cord does not block the air exhaust and access to JRR200 route reflector components or drape where people could trip on it.
- If the AC power source outlet has a power switch, set it to on (|) position. Set the power switch on the JRR200 route reflector to the on (|) position and it will power on.
- If there is no power switch on the AC power source outlet, set the power switch on the JRR200 route reflector to the on (|) position and it will power on.
Verify that the AC and DC LEDs on each power supply are lit green.

Connecting Power to a DC-Powered JRR200 Route Reflector

Before you begin connecting DC power to a JRR200 Route Reflector:

Ensure that you have taken the necessary precautions to prevent electrostatic discharge (ESD) damage.
Ensure that you have connected the chassis to earth ground.

CAUTION:
Before you connect power to the JRR200 route reflector, a licensed electrician must attach a cable lug to the grounding cable 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 properly ground the JRR200 route reflector chassis before connecting power.
Check that the power supplies are fully inserted into the chassis.

Ensure that you have the following parts and tools available:

DC power source cables (14–16 AWG) with ring lug
Phillips (+) screwdriver, number 2
Multimeter

To connect DC power:

Warning:

Before performing the following procedure, ensure that there is no power in the DC circuit. To ensure that all power is cut off, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the off (0) position, and tape the switch handle of the circuit breaker in the off position.

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to the ESD point on the rear of the chassis.
Ensure 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.
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 high resistance (indicating an open circuit) to chassis ground is negative (–) and will be installed on the V– (input) DC power input terminal.
- The cable with very low resistance (indicating a closed circuit) to chassis ground is positive (+) and will be installed on the V+ (return) 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 terminal studs on each power supply.
Remove the protective cover from the terminal studs on the faceplate. Save this cover for future use.
Remove the screws on the terminals by using a number 2 Phillips (+) screwdriver.
Secure each positive (+) DC source power cable lug to a RTN (return) terminal. Secure each negative (–) DC source power cable lug to a -48 V (input) terminal.
Tighten the screws on the power supply terminals until snug using the screwdriver. Do not overtighten.
Replace the protective cover over the terminal studs on the faceplate.
Switch the circuit breaker to the ON (|) position.
Verify that the IN and OUT LEDs on the power supply are lit green and are on steadily.
