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.
