Wall Mount Dimension and Instructions (Optional:
WK-112-01)
NOTE
The wall-mount kit is certified for Hazardous Location usage.
Mounting the switch to a wall requires four screws per
kit
(there are two kits). The heads of the screws
should be between 6.0 to 9.0 mm in diameter, and the
diameter of screw thread should be between 3.5 to 4
mm, as shown in the figure on the right. Use the
switch with the wall
-mounting kit attached as a guide
to mark the correct locations of the eight screws.

Rack-mounting Kit Dimensions and Instructions
(Optional: RK-3U-02)
Please refer to the RK-3U-02 Series QIG.
Matters That Require Attention
1. Elevated Operating Temperature:If installed in a closed or
multi-unit rack assembly, the operating ambient temperature of
the rack environment may be greater than room temperature.
Therefore, consideration should be given to installing the
equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.
NOTE
In order to ensure reliable operations, please make sure the
operating temp
erature of the environment does not exceed the
spec. When mounting a rack
-mounted switch with other
operating units in a cabinet without forced ventilation, it is
recommended that 1U of space is reserved between each rack
-
mounted switch and/or device.
2. Required Air Flow: Installation of the equipment in a rack should
be such that the amount of air flow required for safe operation of
the equipment is not compromised.
3. Mechanical Loading: Mounting of the equipment in the rack
should be such that a hazardous condition is not achieved due to
uneven mechanical loading.
4. Circuit Overloading: Consideration should be given to the
connection of the equipment to the supply circuit and the effect
that overloading of the circuits might have on overcurrent
protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this
concern.
5. Reliable Grounding: Reliable grounding of rack-mounted
equipment should be maintained. Particular attention should be
given to supply connections other than direct connections to the
branch circuit (e.g. use of power strips).
ATTENTION
Safety First
!
Be sure to disconnect the power cord before installing and/or
wiring your Ethernet Switch. Calculate the maximum
possible
current in each power wire and common wire. Observe all
electrical codes dictating the maximum current allowable for
each wire size. If the current goes above the maximum ratings,
the wiring could overheat,
which can cause serious damage to
your equipment.
WARNING
When end users are
using Optical SFP Communications
modules, these must be limited to Laser Class 1.

Connecting the Power Inputs
NOTE
The required power module depends on the choice of LM-7000H
module. Refer to the following power/module combination
requirements.
•
LM-7000H non-PoE modules:
Any power module
•
LM-7000H PoE modules:
PWR-HV-P48-A, PWR-LV-P48-A only
The MDS-G4000-4XGS/MDS-G4000-L3-4XGS Series supports 4 types of
power supply:
•PWR-HV-P48-A: one 110/220 VAC/VDC (90 to 264 VAC, 88 to 300
VDC), one 48 VDC PoE power input for PoE+ ports.
•PWR-LV-P48-A: one 24/48 VDC (18 to 72 VDC), one 48 VDC PoE
power input for PoE+ ports.
•PWR-HV-NP: one 110/220 VAC/VDC (90 to 264 VAC, 88 to 300
VDC) power input.
•PWR-LV-NP: one 24/48 VDC (18 to 72 VDC) power input.
For the PWR-HV-P48-A, the 110/220 VAC/VDC power supplies provide
power to the switch. Separate 48 VDC power supplies are required to
provide power to all PoE+ ports (50 to 57 VDC is recommended for
IEEE 802.3at devices. The maximum PoE output from an external
power supply is 720 W when the operating temperature is under 60°C;
360 W when the operating temperature is under 75°C.)
For the PWR-LV-P48-A models, the 24/48 VDC power supplies provide
power to the switch. Separate 48 VDC power supplies are required to
provide power to all PoE+ ports (50 to 57 VDC is recommended for
IEEE 802.3at devices. The maximum PoE output from an external
power supply is 720 W when the operating temperature is under 60°C;
360 W when the operating temperature is under 75°C.)
For the PWR-HV-NP, the 110/220 VAC/VDC power supplies provide
power to the switch. For the PWR-LV-NP, the 24/48 VDC power supplies
provide power to the switch.
Power Terminal Blocks
The connections for the power input are on the power modules.

- 8 -
PWR-HV-P48-A/PWR-HV-NP
Step 1: Insert the neutral/line (L/N/Ground) AC wires into the
terminals.
Step 2: Insert the terminal block connector into the terminal block
receptor.
PWR-LV-P48-A/PWR-LV-NP
Step 1: Insert the negative/positive (-/+) DC wires into the terminals.
Step 2: Insert the terminal block connector prongs into the terminal
block receptor.
PoE Power Terminal Blocks
Step 1: Insert the negative/positive DC wires into the -/+ terminals,
respectively.
Step 2: Insert the terminal block connector prongs into the terminal
block receptor.
NOTE
In order to have higher levels of protection against surge, it is
suggested to install
a surge protector in front of the power
input of the PoE powered device so that it is suitable for use in
IEC 61850 conditions.
WARNING
When wiring the power input, we suggest using the cable type -
AWG
(American Wire Gauge) 16 (1.31 mm2) and the
corresponding pin type cable terminals. The rated temperature
of the wiring should be at least 105°C and the wire type should
be CU.

NOTE
When two power units are installed on the MDS-G4000-
4XGS/MDS
-G4000-L3-4XGS Series
switch, both power units will
be activated simultaneously, which will enab
le power
redundancy.
NOTE
The reverse power input connection will not activate the device
or PoE input. In addition, the PoE will only activate when the
external power supply is installed on the same power unit.
Wiring the Relay Contact
Each power module has one relay output that can provide two types of
relay output. Refer to the table below for detailed information.
The relay contact is used to detect user-configured events. Two wires
are attached to the relay pins with normally close and normally open
options.
FAULT: The relay contact of the 3-pin terminal block connector is used
to detect user-configured events. The module provides normally open
and normally closed circuits depending on what the user chooses. For
pin definitions, refer to the table below.

WARNING
When wiring the relay contact, we suggest using the cable type
-
AWG (American Wire Gauge) 16-21 (1.31-0.412 mm2) and
the corresponding pin type
cable terminals. The rated
temperature of the wiring should be at least 105°C
and the wire
type should be CU.
Digital Input/Output
Digital Output
1 relay output with a current carrying capacity of 2 A @ 30 VDC.
Digital Input
1 digital output with the same ground, but electrically isolated from the
electronics.
•+13 to +30 V for state 1
•-30 to +1 V for state 0
•Max. input current: 8 mA

WARNING
When wiring the Digital Input/Output contact, we suggest using
the cable
type - AWG (American Wire Gauge) 16-28 (1.31-
0.081 mm
2) and the corresponding pin type cable terminals.
The rated temperature of the wiring should be at least 105°C
and the wire type should be CU.
Installing and Removing the Ethernet Modules
The Ethernet modules are hot-swappable for the same module type.
You can mount or remove the Ethernet module while the device is
operating.
NOTE
1.
When performing a cold start, you cannot remove and
insert a module before the device has fully booted up as
this will cause the module to fail initialization.
2.
The default module is 4XGS. If this is the first time
mounting a 4TX or SFP module, please reboot the switch
after inserting it. The hot-swappable function, as defined
above, will work after the device is rebooted for the first
time.
3.
When swapping out a slotted module with a different type
of module, it is recommended to reconfigure the settings
or
reset the device to factory default settings after rebooting
the switch.
The installation procedure is as follows:
1. Insert the Ethernet module straight into the slot
2. Fasten the module to the device by tightening the 2 screws. The
tightening torque is 3.5 kgf-cm (0.35 Nm)
The removal procedure is as follows:
1. Loosen the 2 screws of the module
2. Pull the module out of the slot
3. Insert the dummy module into the slot in order to have better
protection against dust and EMI
4. Fasten the dummy module using the 2 screws. The tightening
torque is 4 kgf-cm (0.4 Nm)
Installing and Removing the Power Modules
The power supply units are hot-swappable when both power modules
are installed. You can mount or remove the power supply units while
the device is operating.
The installation procedure is as follows:
1. Insert the power unit straight into the slot
2. Fasten the unit to the device by tightening the 2 screws. The
tightening torque is 3.5 kgf-cm (0.35 Nm)
The removal procedure is as follows:
1. Loosen the 2 screws of the module
2. Pull the module out of the slot
