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 http://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.

Only trained and qualified personnel should install or replace the platform.
Perform only the procedures described in this Quick Start or the JCS 1200 Platform Hardware Guide. Other services should be performed by authorized service personnel only.
Read the installation instructions before you connect the platform to a power source.
Before installing the platform, read the guidelines for site preparation in the JCS 1200 Platform Hardware Guide to make sure that the site meets power, environmental, and clearance requirements for the platform.
When installing the platform, do not use a ramp inclined more than 10 degrees.
Manually installing the platform requires four people to lift. Before lifting the chassis, remove components and attach the installation handle as described in the JCS 1200 Platform Hardware Guide. To prevent injury, keep your back straight and lift with your legs, not your back.
Mount the platform at the bottom of the rack if it is the only unit in the rack.
When mounting the platform in a partially filled rack, load the rack from the bottom to the top, with the heaviest component at the bottom of the rack.
If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the platform in the rack.
When removing or installing an electrical component, always place it component-side up on a flat antistatic surface or in an electrostatic bag.
When you install the platform, always make the ground connection first and disconnect it last.
Wire the DC power supply using the appropriate lugs. When connecting power, the proper wiring sequence is ground to ground, +RTN to +RTN, then –48 V to –48 V. When disconnecting power, the proper wiring sequence is –48 V to –48 V, +RTN to +RTN, then ground to ground. Always connect the ground wire first and disconnect it last.
Do not work on the system or connect or disconnect cables during electrical storms.
Before working on equipment that is connected to power lines, remove jewelry, including rings, necklaces, and watches. Metal objects heat up when connected to power and ground and can cause serious burns or become welded to the terminals.
Failure to observe these safety warnings can result in serious physical injury.

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.
