to configuration guide.
Terminology explanation
10BASE-T Brief terminology of IEEE 802.3 for LANs, operates at 10Mbps based
on Manchester coding and uses category-3 or better twisted-pair cable.
100BASE-TX Brief terminology of IEEE 802.3 for LANs, operates at 100Mbps based
on 4B/5B coding and uses category-5 twisted-pair cable.
auto-negotiation Auto-Negotiation detects the various modes that exist in the device on
the other end of the wire, the Link Partner, and advertises its own
abilities to automatically configure the highest performance mode of
interoperation.
Full-duplex Transmission of data in two directions simultaneously
Half-duplex Data can be transmitted in both Rx and Tx directions on a signal
carrier, but not at the same time.
RJ-45 An eight-wire connector used in twister pair wire
MDI Medium dependent interface, provides the physical and electrical
connection to the cabling medium.
MDIX MDI crossover, a version of MDI that enables connection between like
devices.

1. 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.
1.1. 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 operator’s eyes.
1.2. Handling Energized Products
1.2.1 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.
1.2.2 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.
1.2.3 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
Raisecom Technology Co., Ltd

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.
1.3. 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.
