Connectors
LAN and Fiber Connection
IMC-1000-PH(E)12 & IMC-1000S-PH(E)12 have one electrical
LAN port and one fiber port (Fixed type or SFP) on the front panel.
The LAN port that utilizes shielded RJ-45 connectors supports
10/100/1000M; while the fiber port supports fixed speed
100/1000M or dual rate 100/1000M (SFP option) .
PoE Port
The LAN port supports PoE (Power over Ethernet) per
IEEE802.3af (15.4W) or IEEE802.3at (30W) for connection to
standard PoE PD (Power Devices) such as IP Cameras, Access
Points, IP Phones, Digital Signage, etc. PoE eliminates the need to
run separate power to these devices thereby simplifying
deployment and reducing expenses.
The LAN port may also connect to any non-PoE device for
normal Ethernet transmission without any damage to the non-
PoE device or to this device.

Description
1
OFF *
Enable
Power Alarm
Provide an alarm indication when either
power input loses power.
ON
Disable
Power Alarm
No alarm when either power input loses
power.
2
OFF *
Enable
Port Alarm
Provide an alarm indication when either
copper or fiber port loses link.
ON
Disable
Port Alarm
No alarm when either copper or fiber port
loses link.
3
OFF *
Disable LFP
Disable LFP (Link Fault Pass through).
ON
Enable LFP
LFP (Link Fault Pass through) allows a link
condition to be passed from fiber to TP or
from TP to fiber.
NOTE:
LFP is available when the converter is set
to 'Switch' mode (DIP No. 4 is OFF).
4
OFF *
Switch Mode
The device acts as a store & forward device
supporting MAC learning and filtering.
ON
Pass Through
Mode
The device acts as pure 'converter' that the
internal switch is bypassed, enabling low
latency and jumbo (unlimited) frame
support. Do not enable LFP in this mode or
fiber may not link.
NOTE:
LAN and Fiber speed must match when
configured in converter mode. If fiber speed is
1000M, UTP speed must be 1000M.
5
OFF *
1000M
Force the FX port speed to 1000M.
ON
100M
Force the FX port speed to 100M.
NOTE:
Please ensure that the SFP module used is
capable of operating in the dual rate.
6
OFF*
Enable PoE
Enable PoE power output function.
ON
Disable PoE
Disable PoE power output function.
7
OFF*
Disable
Remote PD
Reset
Disable remote PD reset function.
ON
Enable
Remote PD
Reset
When DIP 7 is set to ON, the PSE deice
upon the loss of fiber link will stop supply
power for 3 seconds to the connected PD
device. This will force the PD device to
power off and then power on.

Reserved for future use
NOTE 1:
By default, all DIP switches are set to OFF (marked with *).
NOTE 2:
After changing the DIP switch setting, you must restart the device to activate the
setting.

Power and Alarm
Power
(PWR1, PWR2)
There are input connectors for two power
sources on the terminal block. Only one power
source is required for normal operation. The
second power source input may be provided for
redundancy.
Alarm
The alarm relay contact can be wired into an
alarm circuit which senses an alarm condition
when the contact is broken. The alarm relay is
normally closed when there is no alarm
condition (See Figure 5). The alarm conditions
are selectable through DIP Switch to include
power and link faults. Please note that the
alarm relay contact can only support 1A current
at 24VDC. Do not apply voltage and current
that exceed these specifications.
