Wall-mount plate mounting
To install the
industrial
PoE+ switch on the wall,
follow the
steps
below
.
1.
Remove the DIN
-r
ail from the industrial
PoE+ switch.
L
oosen
the screws to remove the DIN
-rail.
2. Place the wall-
mount plate
s on the rear panel
of the
industrial
PoE+ switch
as shown below
.
3. Use the screws to screw the wall-
mount plate
s on the
industrial
PoE+ switch.
4.
Use the hook holes at the corners of the wall
-
mount plate
s
to hang the
industrial
PoE+ switch on the wall.
5. To remove the wall-
mount p
lates, reverse the steps
above.
Installation Steps
This section describes the functionalities of the Industrial PoE+
components and guides how to install it on the desktop. Basic
knowledge of networking is assumed. Please read this chapter
completely before installation.
1. Unpack the
industrial
PoE+ switch.
2.
Check the DIN
-
Rail
that is pre-installed on the
industrial
PoE+ switch.
(Please refer to DIN
-
Rail Mounti
ng section
for DIN
-
Rail installation
.
If you want to wall mount the
industrial
PoE+ switch
, then please refer to Wall Mount
Plate Mounting section for specific instructions
.
3. To hang the
industrial
PoE+ switch
on the DIN
-
Rail track
or wal
l, please refer to the Mounting section.
4. Power on the
industrial
PoE+ switch.
(Please refer to the
Wiring the Power Inputs section
for power input)
The
power LED on the industrial
PoE+ switch
illuminates.
Please refer to the LED i
ndicato
rs section for LED
definitions
.
5. Prepare the twisted-
pair, straight through Category 5 cable
for Ethernet connection.
6.
Insert one side of Category 5 cables into the industrial
PoE+ switch
Ethernet port (RJ
-45 port) and the other side
to the network device
Ethernet port (RJ
-
45 port), ex:
S
witch, PC,
or Server. The UTP port (RJ
-
45) LED on the
industrial
PoE+ switch
illuminates
when the cable
is
connected to the network d
evice. Please refer to the LED
i
ndicators section for LED definitions
.
7.
Insert
the
fiber cable from the industrial PoE+ switch
to the
fiber network. TX, RX must be paired at both ends
. The
optical
port LED on the MC252
-4P-
1S
illuminates
when
the
connection is established
with a network device.
Please refer to the LED indicators section for LED
definitions
.
8. When all connections are set
up
and the LEDs illuminate,
the installation is complete.
Troubleshooting
This section contains
issue
-solving
inform
ation
. If the industrial
PoE+ switch
is not functioning properly,
en
sure th
at the
industrial
PoE+ switch
was set up according to instructions in
this manual.
Issue
Solution
The per port LED does
not illuminate.
Check the cable connection and try
swapping out a cable.
Performance is poor
Check the speed duplex mode of the
partner device. The industrial PoE+
switch is run in auto-negotiation mode
and if the partner is set to half duplex,
then the performance will be poor.
The per port LED
illuminates, but the
traffic is irregular.
Ensure that the attached device is not
set to dedicated full duplex. Some
devices use a physical or software
switch to change duplex modes. Auto-
negotiation may not recognize this type
of full-duplex setting.
The industrial PoE+
switch doesn’t
connect to the network
Check the per port LED and/or try
another port on the industrial PoE+
switch. Ensure that the cable is installed
properly and is the correct type. Turn off
the power and then, after a while, turn
on the power again.
