Safety Warnings

Warning: See installation instructions before connecting the platform. This is a summary of safety warnings. For a complete list of warnings for this platform, including translations, see the JCS 1200 Platform Hardware Guide at https://www.juniper.net/techpubs/hardware/.

Warning: The intrabuilding port(s) of the router is suitable for connection to intrabuilding or unexposed wiring or cabling only. The intrabuilding port(s) of the router MUST NOT be metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use as intrabuilding interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition of primary protectors is not sufficient protection to connect these interfaces metallically to OSP wiring.

Caution: Before removing or installing components of a router, attach an ESD strap to an ESD point and place the other end of the strap around your bare wrist. Failure to use an ESD strap could result in damage to the platform.

Warning: Electrical current from power, telephone, and communication cables is hazardous.

To avoid a shock hazard:

  • Do not connect or disconnect any cables or perform installation, maintenance, or reconfiguration of this product during an electrical storm.
  • Connect all power cords to a properly wired and grounded power source.
  • Connect to properly wired power sources any equipment that will be attached to this product.
  • When possible, use one hand only to connect or disconnect signal cables.
  • Never power on any equipment when there is evidence of fire, water, or structural damage.
  • Disconnect the attached AC power cords, DC power sources, network connections, telecommunications systems, and serial cables before you open the component covers, unless you are instructed otherwise in the installation and configuration procedures.
  • Connect and disconnect cables as described in the following procedures when you install, move, or open covers on this product or attached components.

    To connect power sources:

    1. Turn OFF all power sources and equipment that are to be attached to this product.
    2. Attach signal cables to the product.
    3. Attach power cords to product.
      • For AC systems, use appliance inlets.
      • For DC systems, ensure correct polarity of –48 V DC connections: RTN is + and –48 V DC is –. Earth ground should use a two-hole lug for safety.
    4. Attach signal cables to other components.
    5. Connect power cords to their sources.
    6. Turn ON all the power sources.

    To disconnect power sources:

    1. Turn OFF all power sources and equipment that are attached to this product.
      • For AC systems, remove all power cords from the chassis power receptacles for interrupt power at the AC power distribution unit.
      • For DC systems, disconnect DC power sources at the breaker panel or by turning off the power source. Then remove the DC cables.
    2. Remove signal cables from connectors.
    3. Remove all cables from components.

Warning: When installing laser products (such as fiber-optic devices or transmitters), note the following:

  • Do not remove the covers. Removing the covers of the laser product could result in exposure to hazardous laser radiation. There are no serviceable parts inside the component.
  • Use of controls or adjustments or performance of procedures other than those specified here might result in hazardous radiation exposure.

Warning: Some laser products contain an embedded Class 3A or Class 3B laser diode. Note the following:

There is laser radiation when open. Do not stare into the beam, do not view directly with optical instruments, and avoid direct exposure to the beam.

Caution: The power control button on the component and the power switch on the power supply do not turn off the electrical current supplied to the component. The component also might have more than one power cord. To remove all electrical current from the component, disconnect all power cords from the power source.

Caution: Hazardous energy is present when the Routing Engine is connected to the power source. Always replace the Routing Engine cover before installing the Routing Engine.

Warning: Handling the cord on this product or cords associated with accessories sold with this product, will expose you to lead, a chemical known to the State of California to cause cancer, and birth defects or other reproductive harm. Wash hands after handling.

ADVERTENCIA: El contacto con el cable de este producto o con cables de accesorios que se venden junto con este producto, pueden exponerle al plomo, un elemento qumico que en el estado de California de los Estados Unidos est considerado como un causante de cancer y de defectos congnitos, adems de otros riesgos reproductivos. Lvese las manos despus de usar el producto.
