Wall Mount Dimension and Instructions (Optional:
WK-112-01)
Mounting the switch to a wall requires four screws. 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 shown
on the right
. Use the MDS-G4000 Series with the wall
mounting kit attached, as a guide to mark the correct
locations of the eight screws.
Rack Mounting Dimension and Instructions
(Optional: RK-3U-01)
The rack mount kit is designed for two MDS-G4028 products. To mount
the rack mount kit, please assemble the right and left part of the kit
(indicated with No. 1 below) with four screws. Then assemble the part
of the rack kit (indicated with No. 2 below) with eight screws in order to
combine the two MDS-G4028 products.

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.

- 7 -
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.
Connecting the Power Inputs
The MDS-G4000 Series supports 2 types of power supply:
•PWR-HV-P48: one 110/220 VAC/VDC (90 to 264 VAC, 88 to 300
VDC), one 48VDC PoE power input for PoE+ ports.
•PWR-LV-P48: one 24/48 VDC (18 to 72 VDC), one 48 VDC PoE
power input for PoE+ ports.
For the PWR-HV-P48, 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 max. 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 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 max. 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.)

Power Terminal Blocks
The connection for power input and PoE external power supply is on the
power modules.
PWR-HV-P48
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
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.

- 9 -
NOTE
When wiring the power input, we suggest using the cable type -
AWG (American Wire Gauge) 18 (1.03
mm2) and the
corresponding pin type cable terminals. The connector must be
able to withstand torque at maximum 5 pound
-inches. The
rated temperature of wiring should be at least 105°C.
NOTE
When two power units are installed on the MDS
-G4000 Series
switch, both power units will be activated simultaneously, which
will enable 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.

NOTE
When wiring the relay contact, we suggest using the cable type
-
AWG (American Wire Gauge) 16-24 (1.31-0.205 mm2) and
the corresponding pin type cable terminals. The connector must
be able to withstan
d torque at maximum 5 pound-inches. The
rated temperature of wiring should be at least 105°C.

Install/Remove the Ethernet module
The Ethernet modules are hot-swappable for the same module type.
You have the option to 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 booting up as it will cause the
module to initially fail.
2.
The default module is 4GTX, if it is the first time to mount
4TX, PoE, 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.
If a different model type module is changed on the same
slot, it is recommend to reconfigure the settings or reset
the device to 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 in to the slot in order to have better
protection against dust and EMI
4. Fasten the dummy module using 2 screws. The tightening torque is
4 kgf-cm (0.4 Nm)
Install/Remove the Power module
The power supply units are hot-swappable when both power modules
are installed. You have the option to 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
3. Insert the dummy module in to the slot in order to have better
protection against dust and EMI.
4. Fasten the dummy module using 2 screws. The tightening torque is
4 kgf-cm (0.4 Nm)
NOTE
If one of the modules is removed from the device, it is
advisable to insert a dummy module in order to provide better
protection against dust and EMI.
