Site Selection
Choose a site that is:
Away from sources of vibration or physical shock.
Isolated from strong electromagnetic fields produced by electrical devices.
Provided with a properly grounded wall outlet.
Provided with sufficient space to access the power system.
The system is intended for installation only in Restricted Access
Locations:
access can only be gained by SERVICE PERSONS or by USERS
who have been instructed about the reasons for the restric-
tions applied to the location and about any precautions that
shall be taken; and
access is through the use of a TOOL or lock and key, or other
means of security, and is controlled by the authority responsi-
ble for the location.
Warning and Cautions (Continued)

IRONRAN-RU4 MO GENA PRECAUTIONARY MEASURES
VII
Equipment Handling Practices
Reduce the risk of personal injury or equipment damage:
Conform to local occupational health and safety requirements when moving and
lifting equipment.
Use mechanical assistance or other suitable assistance when moving and lifting
equipment.
To reduce the weight for easier handling, remove any easily detachable
components.
Never lift or move your system solely by the handle on the component.
The power supply cord(s) must be plugged into the socket-outlet(s) that is / are
provided with a suitable earth ground.
Laser Class 1 optical transceiver shall be used only.
This is a Class 1 Laser product. Use only IEC 60825-1 certified Optical Fiber
Transceiver with minimum operating temperature at 75 degree C.
Never open the equipment. For safety reasons, the equipment should be opened
only by qualified skilled personnel.
The system can’t be hosed down or splashed with water.
Power and Electrical Warnings
CAUTION!
Double Pole / Neutral Fusing.
CAUTION!
Must use current limiting type circuit breaker, peak current < 300 A.
CAUTION!
Make sure the system is removed from the pole or wall before servicing any
components.
CAUTION!
To avoid risk of electric shock, disconnect all cabling from the system and
remove the system from the pole or wall.
CAUTION!
For IronRAN-RU4 MO GenA devices stored in -40°C environments for over 1
hour, a warm up period of 1.5 hours is required before cell connection.

System Access Warnings
Electrostatic Discharge (ESD)
Always handle boards carefully. They can be extremely sensitive to ESD. Hold boards only
by their edges without any component and pin touching. After removing a board from its
protective wrapper or from the system, place the board component side up on a
grounded, static free surface. Use a conductive foam pad if available but not the board
wrapper. Do not slide board over any surface.
CAUTION!
To avoid personal injury or property damage, the following safety instructions
apply whenever accessing the inside of the product:
Disconnect from the power source by removing the system from the pole
or wall.
Disconnect all cabling running into the system.
Retain all screws or other fasteners when servicing. Upon completion ser-
vicing, secure with original screws or fasteners.
CAUTION!
If the system has been running, any installed components may be hot.
CAUTION!
Unless you are adding or removing a hot-plug component, allow the system to
cool before servicing.
CAUTION!
To avoid injury do not contact moving fan blades. If your system is supplied
with a guard over the fan, do not operate the system without the fan guard in
place.
CAUTION!
ESD can damage drives, boards, and other parts. We recommend that you
perform all procedures at an ESD workstation. If one is not available, provide
some ESD protection by wearing an anti-static wrist strap attached to chassis
ground -- any unpainted metal surface -- on your device when handling parts.

Cooling and Airflow
Please be aware that slots and openings on the front and rear side of the chassis are
designed for ventilation; to make sure reliable operation of your system and to protect it
from overheating, these openings must not be covered or blocked. The openings should
never be covered or blocked by placing the product on a bed, sofa, rug, or other similar
surface. This product should never be placed near or over a radiator or heat register, or in a
built-in installation unless proper ventilation is provided.
Heed safety instructions: Before working with the system, whether using this manual or
any other resource as a reference, pay close attention to the safety instructions. Adhere to
the assembly instructions in this manual to ensure and maintain compliance with existing
product certifications and approvals. Use only the described, regulated components
specified in this manual. Use of other products / components will void other safety
regulatory approvals of the product and will most likely result in non-compliance with
product regulations in the region(s) in which the product is sold.
System power on/off: To remove power from system, you must remove the system from
the pole or wall. Make sure the system is removed from the pole or wall before opening
the chassis, adding, or removing any non hot-plug components.
Hazardous conditions, devices and cables: Hazardous electrical conditions may be
present on power, telephone, and communication cables. Turn off the system and
disconnect the cables attached to the system before servicing. Otherwise, personal injury
or equipment damage can result.
Electrostatic discharge (ESD) and ESD protection: ESD can damage drives, boards, and
other parts. We recommend that you perform all procedures in this chapter only at an ESD
workstation. If one is not available, provide some ESD protection by wearing an
nonconductive wrist strap attached to chassis ground (any unpainted metal surface on
the device) when handling parts.
ESD and handling boards: Always handle boards carefully. They can be extremely
sensitive to electrostatic discharge (ESD). Hold boards only by their edges. After removing
a board from its protective wrapper or from the system, place the board component side
up on a grounded, static free surface. Use a conductive foam pad if available but not the
board wrapper. Do not slide board over any surface.
CAUTION!
Carefully route cables as directed to minimize airflow blockage* and cooling
problems. For proper cooling and airflow*, operate the system only with the
chassis covers* / air duct* installed. Operating the system without the covers /
air duct* in place can damage system parts. To install the covers* / air duct*:
Check first to make sure you have not left loose tools or parts inside the
system.
Check that cables, add-in cards, and other components are properly
installed.
Attach the covers* / air duct* to the chassis according to the product
instructions.
* May not apply to all systems.

General Information
Before servicing this system, it is recommend to read this guide completely to be aware of
any safety issues or requirements involved in the servicing of this system.
Assembly Safety Guidelines
Choose a site that is:
Away from sources of vibration or physical shock.
Isolated from strong electromagnetic fields produced by electri-
cal devices.
In regions that are susceptible to electrical storms, we recom-
mend you plug your system into a surge suppressor and discon-
nect telecommunication lines to your modem during an
electrical storm.
Provided with a properly grounded wall outlet.
Provided with sufficient space to access the power system,
because they serve as the product's main power disconnect.
