Note
WEEE Directive Symbol (Applicable in the European Union
and other European countries with separate collection
systems).This symbol on the product or its packaging
indicates that this product must not be disposed of with
other waste. Instead, it is your responsibility to dispose of
your waste equipment by handing it over to a designated
collection point for the recycling of waste electrical and
electronic equipment. The separate collection and recycling
of your waste equipment at the time of disposal will help
conserve natural resources and ensure that it is recycled in
a manner that protects human health and the environment.
For more information about where you can drop off your
consumer waste equipment for recycling, please contact
your local city recycling office or the dealer from whom you
originally purchased the product.

2.1 SAFETY WARNINGS
Before to continue, read carefully the following safety warnings:
Prior to installation carefully read the whole guide.
Pay attention to the safety instructions during installation, operation or
maintenance of this product. Installation, adjustments or maintenance
must be performed only by qualified, trained and authorized personnel.
To prevent the risk of electrical shocks, before turning the equipment on
or connecting an interface card or cable, install the protective grounding
system.
Before connecting any cable to the equipment, make sure that the
grounding system is functional.
Optical Transceivers used in DM4270 have invisible LASER emitting.
Although all DATACOM homologated transceivers and most of the market
transceivers comply with LASER safety standards, avoid direct contact
and exposure to eyes and skin.
The optical modules use invisible radiation laser transmitters. Although
most SFP/SFP+/QSFP+/QSFP28 on the market meet LASER safety
specifications, never look directly at the terminals of a module or an
optical cord. Exposure to laser emissions may cause partial or total loss
of vision.

ON GREEN: Indicates that the power supply is running and that
the equipment is powered or on standby ready to take over the
load.
OFF: Power supply with problems or not powered.
PSU 400 AC
ON GREEN: Indicates that the power supply is running and the
equipment is powered or on standby ready to take over the
load.
ON AMBER: Indicates that the power supply is powered, but is
disconnected from the HW or on standby.
OFF: Power supply with problems or not powered.
LED
ALARM/FAIL
OFF: Equipment operating normally, without detected failures
or alarms.
ON RED: Indicates that the equipment is in a state of internal
failure.
ON BLINKING RED (slow): Indicates that the equipment is in a
lower gravity alarm state.
ON BLINKING RED (fast): Indicates that the equipment is in a
lower gravity alarm state.
When the power is connected to the equipment, this LED will turn
red for a short time, and then will turn off.

3.5 SERIAL CONSOLE INTERFACE (RS-232)
The DM4270 equipment line has a console port for local management. The console port
uses an RJ45 connector. A cable with a male RJ45 connector and a female DB9
connector must be used for the connection to a computer or laptop.
The serial console cable is an accessory included in the DM4270. Additional cables can
be purchased separately via code 710.0137.xx or assembled as described in the
following figures. The pin assignment of the RJ45 connector and its match with the DB9
connector is described in table 4.

3.9.2.4 Changing the configuration mode of the Uplink ports
In the equipment’s CLI interface, it is possible to change the configuration of the 40GbE
and 100GbE uplink ports with the commands listed below, the change requires a full
system reboot.
To change the uplink operation to 4 x 40GE:
DM4270# card-model 24XS+4QX
Warning: The system will automatically reboot and load the factory
configuration. Once initiated, this process cannot be interrupted.
Proceed with this action? [yes,NO]
To change the uplink operation to 2 x 40/100GE:
DM4270# card-model 24XS+2CX
Warning: The system will automatically reboot and load the factory
configuration. Once initiated, this process cannot be interrupted.
Proceed with this action? [yes,NO]
To change the uplink operation to 2 x 40GE + 1 x 40/100GE:
DM4270# card-model 24XS+2QX+1CX
Warning: The system will automatically reboot and load the factory
configuration. Once initiated, this process cannot be interrupted.
Proceed with this action? [yes,NO]
3.9.2.5 40 and 100 Gigabit Optical Ethernet Interface LED indicators
The 40GE and 100GE ports have LEDs that indicate the operation of the ports on the
left front part of the equipment, as shown in figure 13. The convention to indicate the
