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 operator’s 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.

4.4 Power Supply
¾After install the device correctly following above steps, the device can be powered on by
connecting the switch with 220V power supply.
¾PWR indicator ON means the system has been powered on.
¾All the indicator lights on front panel of ON means the system is self-checking and
initializing.
¾After self-check and initialization, the device starts to operate, and then the SYS indicator
starts flickering which means that system operates normally. Indicator LEDs of the 24
Ethernet ports indicate the status of ports (ON or OFF is according to port configuration and
connection).
¾If the CONSOLE port is connected to PC and terminal software is configured correctly
before system powered on, there will be user management interface on the PC screen, and
then operation is available. (Specific operations are available in ISCOM2126EA-MA
Configuration Guide).

Chapter 5 Precautions
Only trained and qualified personnel should install, maintain, or install the parts of
ISCOM2126EA-MA. The device must be installed in a place where temperature and humidity can be
controlled, meanwhile consider the electronic conductivity of surrounding materials. Extreme
moisture may result in short circuit, and if too dry there may be fire. So there must be a suitable
environment for the device.
¾The power supply must be grounded to discharge static.
¾There must be some space between device and the near electrical equipments.
¾We recommend that outside device routing intersect with live wire to avoid long paralleling.
¾Follow the guide strictly when installing.
¾Do not install the device when your hands are wet or with a lot of sweat.
¾Do not rebuild the device mechanically and electrically.
¾When install ISCOM2126EA-MA on the table, please do not put other thing onto it.
