Electrical Current
Electrical current from power, telephone, and
communication cables is hazardous.
1. Do not connect or disconnect any power cables or
perform installation, maintenance, or reconfiguration of
this product during an electrical storm.
2. This apparatus must be properly grounded with a
protective earth contact.
3. The device is intended for use when supplied with
power from a supply providing 100-240 V max;
50/60 Hz 4A per input, -48/-60 Vdc, 8A per input.
4. Power is provided to the ROME chassis by the LCU via
the RCU cable. (270 Vac RMS max; 39 kHz; 0.5A max;
12Vdc; 3A=Powered by LCU.)
5. Disconnect power (following proper shutdown
procedures), telecommunications systems, networks,
and modems before you open the device covers.
Remove all jewelry (including rings, necklaces, and
watches), wear a grounding wrist strap, and do not
directly touch the backplane with your hand or any
metal tool, to avoid possible shocks, burns, or ESD
damage to the unit.
6. Never turn on any equipment when there is evidence
of fire, water, or structural damage.
7. DO NOT OPEN ROME Unit when power is on. Hazardous
voltages exist within the unit as well as moving parts
that may cause injury. This product contains no user-
serviceable parts. The unit may be opened ONLY by
trained and qualified personnel.
Proper Grounding Required
This equipment must be grounded. Never defeat the
ground conductor or operate the equipment in the
absence of a suitably installed ground conductor. Contact
the appropriate electrical inspection authority or an
electrician if you are uncertain that suitable grounding
is available. When installing or replacing the unit, the
ground connection must always be made first and
disconnected last.
Avoiding Circuit Overload
Overloading a circuit is potentially a fire hazard and a
shock hazard under certain conditions. To avoid these
hazards:
1. Take care when connecting units to the supply circuit
so that wiring is not overloaded.
2. Ensure that your system's electrical requirements do
not exceed the branch circuit protections requirements.
Refer to ROME's electrical specifications.
3. An over current protection device (15A branch circuit
breaker) should be incorporated into the building
installation.

Possible Laser Hazard
This device can switch laser based source signals, which,
at higher wattage levels, require additional precautions
by the user. Since it is the user that determines what
signals are transmitted through this device, and not the
device manufacturer, it is the responsibility of the user
to take the necessary precautions as dictated by the
source equipment generating the signals in question. It
is recommended that the user add any warning labels to
this device, as necessary, in the case of higher level laser
sources that may be potentially harmful if exposed to the
user.
Extending Devices Forward in Rack
Do not extend more than one sliding device at a time.
Caution
This unit has more than one power supply cord.
Disconnect power supply cords before servicing to avoid
electric shock.
The products were tested in a branch circuit protected
by a 20 A circuit breaker (AC Input) and 32 A (DC Input).
Additional evaluation shall be conducted if a higher
protector is to be used in the end system.
The mains supply cord set used to connect the
equipment to supply mains must be of an approved type
acceptable to the authorities in the country where the
equipment is sold.
The plug on the power supply cord is intended to serve as
the disconnect device, the socket-outlet shall be installed
near the equipment and shall be easily accessible.
