Regulatory Compliance and Safety Information for the Cisco 1000 Series Connected Grid Routers

blank.gifClass A Notice for FCC

blank.gifClass A Notice for Canada

Class A Notice for FCC

Modifying the equipment without Cisco's authorization may result in the equipment no longer complying with FCC requirements for Class A digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case users will be required to correct the interference at their own expense.

Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

Cet appareil numérique de la classe A est conforme à la norme NMB-003 du Canada.

This device complies with Industry Canada (IC) license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device.

Safety Information

When connecting the router to AC power, you must ensure that the following conditions are met:

blank.gifAC power is available at the installation location.

blank.gifAC power can be readily and conveniently removed from the router. The power should not be removed by disconnecting the AC power connector on the unit.

Warning: The plug-socket combination must be accessible at all times, because it serves as the main disconnecting device. Statement 1019

Warning: Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030

Warning: Installation of the equipment must comply with local and national electrical codes. Statement 1074

Warning: Before connecting or disconnecting the power cord, you must remove AC power from the power cord using a suitable service disconnect.

blank.gifWhen you install the unit outdoors, or in a wet or damp location, the AC branch circuit that powers the unit should have ground fault protection (GFCI), as required by Article 210 of the NEC.

blank.gifEnsure that the user-supplied AC power plug is certified for outdoor use and has a minimum rating, such as Interpower 84131251 or Hubbell HBL316P6W (IEC/EN60309 pin-and-sleeve type connectors).

blank.gifIf the power cord goes through a metal cover, a bushing should be installed to prevent fraying of the cord. When using a strain relief bushing, follow these recommendations:

blank.gifUse properly sized parts that are suitable for outdoor installation

blank.gifUse bushings that are safety certified

Terminal Blocks and Mating Connectors for Power Input Wiring

The router ships with two connectors used to connect power to the AC and DC power connectors on the router.

blank.gifThe AC power connection mating connector is a 5-way screw terminal printed circuit board plug connector manufactured by Phoenix Contact (part number 1913604). Figure 2 shows the connector.

blank.gifThe DC power connection mating connector is a 2-way screw terminal printed circuit board plug connector manufactured by Phoenix Contact (part number 1912184). Figure 3 shows the connector.

Connect to AC Power

This section describes how to make two the following types of AC power connections to the router:

blank.gifSingle-phase AC

blank.gifThree-phase AC

Note: The AC power connection mating connector shipped with the router is a 5-way screw terminal printed circuit board plug connector manufactured by Phoenix Contact (part number 1913604).

To connect the router to AC power, follow these steps:

Note: The router will power on as soon as it is connected to an AC power source. You are not required to press a power button to power on the router.

 

 

159736.eps

 

Caution: When connecting the router AC power connector, always connect the router end of the cable first. When removing the AC power connector, always disconnect the router end of the cable last.

1.blank.gif Turn off power to the AC power source at the designated circuits.

2.blank.gif Use a wire-stripping tool to strip each of the wires from the AC-input power source. Expose the wire to the appropriate length for the terminal block, about 0.25 inches.

3.blank.gif Insert the wires into the AC power connector terminals described in Figure 1 and Table 1.

Insert wires that correspond to your installation (three-phase or single-phase), as shown in Figure 5.

4.blank.gif After the wires are inserted into the connector terminals, use the screwdriver to tighten the connector screw terminals. The screw terminals are shown in Figure 2.

5.blank.gif Connect the AC power connector to the AC power connection on the router as shown in Figure 4.

6.blank.gif Use the screwdriver to tighten the two captive screws on the connector. The terminal screws are shown in Figure 2. Torque the terminal block screws to 1.243 N-m (11 lbf-in).

7.blank.gif Turn on AC power by plugging in an AC power cord to the power source, or enabling power at the designated circuit. The router will power on and run a series of bootup tests, indicated by blinking LEDs.

Verify AC Power Connection

After you connect the router to AC power, verify that the power is being supplied to the router by checking the status of the SYS (System) LED. As the router starts up, the SYS LEDs show these states:

 

Sequence
State
Description

1

Yellow

System is receiving power.

2

Green blinking

The system is starting up or power cycling, and loading system software, including BIOS and operating system.

3

Green solid

The system is functioning normally.

For the SYS LED location, see Figure 1 in Router LED Locations and States.

Connect to DC Power

You can connect the router to a DC power source as a primary source.

Note: If you are using AC power as the primary source of power to the router, you can also configure DC power as a alternate power source in the event that the AC power source fails or is disrupted.

Note: The AC power connection mating connector shipped with the router is a 2-way screw terminal printed circuit board plug connector manufactured by Phoenix Contact (part number 1912184).

To connect a DC-input power source to the router, follow these steps:

1.blank.gif Turn off power to the DC power source at the designated circuits.

2.blank.gif Using a wire-stripping tool to strip both of the wires from the DC-input power source. Expose the wire to the appropriate length for the DC power connector, about 0.25 inches.

3.blank.gif Insert the wires into the DC power connector terminals described in Figure 1 and Table 1.

Note: When you insert the wires in the terminals as shown in Figure 6, ensure that the polarity matches: negative-to-negative and positive-to-positive).

7.blank.gif Enable DC power by plugging in the DC power supply cord to the power source, or by enabling power at the designated circuit.

 

Power Cycling the Router

There are two reset buttons on the router cable panel, which can be used to power cycle the router and to reset the router system software to the default configuration. Use the reset buttons as described in this section.

Caution: When you use the CONFIG Reset button to restore the router to the factory default software configuration, the current software configuration is permanently deleted from the router.

Accessing the Buttons

You must provide a pin, paper clip, or other thin metal tool to access and press these buttons.

Description

1

CONFIG Reset

Press the CONFIG Reset button for at least 5 seconds to return the router software configuration to the factory default, and power cycle the router. Power cycling the router turns the router off, then immediately back on. The router will temporarily stop operating on the network during the power cycle, then resume operating when the power cycle process is complete.
