General Safety Instructions The following instructions serve as a general guide for the safe installation and operation of telecommunications products. Additional instructions, if applicable, are included inside the manual.

Safety Symbols

This symbol may appear on the equipment or in the text. It indicates potential safety hazards regarding product operation or maintenance to operator or service personnel.

Danger of electric shock! Avoid any contact with the marked surface while the product is energized or connected to outdoor telecommunication lines.

Protective earth: the marked lug or terminal should be connected to the building protective earth bus.

Some products may be equipped with a laser diode. In such cases, a label with the laser class and other warnings as applicable will be attached near the optical transmitter. The laser warning symbol may be also attached. Please observe the following precautions: Before turning on the chassis with optic module, make sure that the fiber optic cable is intact and is connected to the transmitter. Do not attempt to adjust the laser drive current.

Do not use broken or unterminated fiber-optic cables/connectors or look straight at the laser beam.

The use of optical devices with the equipment will increase eye hazard. Use of controls, adjustments or performing procedures other than those specified herein, may result in hazardous radiation exposure. ATTENTION: The laser beam may be invisible!

Always observe standard safety precautions during installation, operation and maintenance of this product. Only qualified and authorized service personnel should carry out adjustment, maintenance or repairs to this product. No installation, adjustment, maintenance or repairs should be performed by either the operator or the user.

All extension slots are not hot-swappable

Before operating modules in the electricity conditions, please be noticed that optical modules shall be connected with optical fiber wires or shield with optical module cover for fear that laser light harms to operators eyes.

Handling Energized Products

General Safety Practices Do not touch or tamper with the power supply when the power cord is connected. Line voltages may

be present inside certain products even when the power switch (if installed) is in the OFF position or a fuse is blown. For DC-powered products, although the voltages levels are usually not hazardous, energy hazards may still exist. Before working on equipment connected to power lines or telecommunication lines, remove jewelry or any other metallic object that may come into contact with energized parts. Unless otherwise specified, all products are intended to be grounded during normal use. Grounding is provided by connecting the mains plug to a wall socket with a protective earth terminal. If an earth lug is provided on the product, it should be connected to the protective earth at all times, by a wire with a diameter of 18 AWG or wider. Rack-mounted equipment should be mounted only in earthed racks and cabinets. Always make the ground connection first and disconnect it last. Do not connect telecommunication cables to ungrounded equipment. Make sure that all other cables are disconnected before disconnecting the ground.

Connection of AC Mains Make sure that the electrical installation complies with local codes. Always connect the AC plug to a wall socket with a protective ground. Always connect the power cord first to the equipment and then to the wall socket. If a power switch is provided in the equipment, set it to the OFF position. If the power cord cannot be readily disconnected in case of emergency, make sure that a readily accessible circuit breaker or emergency switch is installed in the building installation.

Connection of DC Mains Unless otherwise specified in the manual, the DC input to the equipment is floating in reference to the ground. Any single pole can be externally grounded. Due to the high current capability of DC mains systems, care should be taken when connecting the DC supply to avoid short-circuits and fire hazards. DC units should be installed in a restricted access area, i.e. an area where access is authorized only to qualified service and maintenance personnel. Make sure that the DC supply is electrically isolated from any AC source and that the installation complies with the local codes. Before connecting the DC supply wires, ensure that power is removed from the DC circuit. Locate the circuit breaker of the panel board that services the equipment and switch it to the OFF position. When connecting the DC supply wires, first connect the ground wire to the corresponding terminal, then the positive pole and last the negative pole. Switch the circuit breaker back to the ON position. A readily accessible disconnect device that is suitably rated and approved should be incorporated in the building installation.

Preventing Electrostatic Discharge Damage

Modules which can be plugged into chassis are sensitive to damage from static electricity. Conversely, static voltages as high as 35,000V can be generated just by handling plastic or foam packing material, or by sliding assemblies across plastic and carpets. Not exercising the proper electrostatic discharge (ESD) precautions can result in intermittent or complete component failures. To minimize the potential for ESD damage, observe the following guidelines: Always use an ESD-preventive antistatic wrist strap or ankle strap and ensure that it makes good skin contact. When removing or installing a component, make sure the equipment end of your antistatic strap leash is connected to the ESD connection sockets on the front of the chassis or to a bare metal surface on the chassis. Avoid contact between the component and your clothing. The wrist strap only protects the component from ESD voltages on the body; ESD voltages on your clothing can still cause component damage. Always place a card component-side-up on an antistatic surface, in an antistatic card rack, or in a static shielding bag. If you are returning the item to the factory, immediately place it in a static shielding bag. Handle Modules by the metal card carrier edges only; Avoid touching the board or any connector pins.

OFF=full-duplex (default)

The switch is invalid when bit 1 is OFF. The switch determines Ethernet duplex mode when bit 1 is ON.

Bit 4: Fault-Pass-Through switch ON=Open Fault-Pass-Through function.

OFF=Close Fault-Pass-Through function.

Local LOS, LOF, AIS, CRC alarm of E1 link can disable the Ethernet interface, in order to report the link fault to switch. When there is no alarm on E1 link, the Ethernet interface recovers normal working status automatically.

There is no association between the working status of Ethernet interface and E1 alarm if close this function.

Bit 5: remote network management control switch


6

ON=auto-sensing network management position.

OFF=force remote management.

When this bit 5 is OFF, device decides itself as central office device or customer premise device according to chassis. It is central office module, master device mode when it is plugged in RC002-16 or RC002-4 chassis; it is customer premise module, slave device mode when it is plugged in RC001-1 chassis.

The device is forced to be customer premise module, slave device mode when this bit 5 is ON.

Users can configure and manage the device via network management system when it is in master device mode, and the peer slave mode device can be managed by master device; when it is in slave device mode, the local network management can only query status of itself but can not configure.

Note: When connecting two sets of RC952 devices, one must set in master mode, and the other set in slave mode; when connecting to RC951-8FE16E1, RC952-FEE1(-BL) must set in slave mode.

Bit 6: Clock mode switch ON=Slave clock mode

OFF=Master clock mode (default)

If there is timing equipment in E1 link, RC952-FEE1(-BL) of both sites must be set slave clock mode. If there is no timing equipment in E1 link, RC952-FEE1(-BL) of one site is set master clock mode and RC952-FEE1(-BL) of the other site is set slave clock, or RC952-FEE1(-BL) of both sites are set master clock mode.
