• 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.

  strandard, can realize inter-communication and unity management
  with other vendors single E1 interface converter.

  ON OFF Mode 3, inter-connect with Raisecom RC905, RC906 series
  device, can not remtoe manage RC905 and RC906.

  When the device is set mode 2 or mode 3, E1 is unframed mode. So
  the another site equipment must be unframed mode.

  Bit 3: Buffer size optional switch ON=Small buffer

  OFF=Big buffer (default)

  When the equipment uses big buffer, it is suitable for to
  transmit data service, when the equipment uses small buffer, it is
  suitable for to transmit image service.

  Bit 4: Error bits test switch On=Open error bits test
  function

  Off=Close error bits test function (default)

  The function is convenient for users to test network. At
  present, error bits test supports statistic function of ES and SES,
  which is stated in G.821/826 protocol. But statistic period is
  fixed 5 minutes (nonstandard). During the 5 minutes test period,
  status of error bits can be checked through network management.

  The equipment transmits Pseudo-Random Test Sequence at all times
  during the test of error bits, and service and network management
  control will be stopped. So when using the function, remote
  equipment should be set local loop-back status or local equipment
  should be set remote loop-back status.

  Bit 5~7: reserved Bit 8: network management enable switch

  Bit 8 Network management enable switch

  OFF Enable network management function, device can operation
  remtoe management function.
