2-3 RJ-45 Ports
HMG-1648P & HMG-1648EP has 16 10/100Mbps auto-sensing ports for 10Base-T and 100Base-TX devices
connection. Auto MDI/MDIX function allows HMG-1648P & HMG-1648EP to connect to another switch or
workstation without changing straight through or crossover cabling. See RJ-45 Pin Assignment section for
straight through and crossover cable schematic.
2-3.1 RJ-45 Pin Assignments
All ports on HMG-1648P & HMG-1648EP support automatic MDI/MDI-X function, users can use straight-through
cables (see figure below) for all network connections to PCs or servers, or to other switches or hubs. When auto
MDI/MDI-X is enabled, both type of cable can be used and the interface automatically corrects any incorrect
cabling. The table below shows the 10Base-T/100Base-TX MDI and MDI-X port pinouts.

HMG-1648P & HMG-1648EP is equipped with 4 x 100/1000Base SFP fiber port gives users more flexibility in
choosing fiber modules to fit the existing network structure on the plant floor.
2-5 Console Port
HMG-1648P & HMG-1648EP has an asynchronous terminal console port for local management via a serial
terminal. The terminal provides management via a CLI (Command Line Interface) which will be familiar to many
networking engineers. For most users, the CLI can be used to initially configure TCP/IP access so that further
configuration can be completed via the GUI (Graphical User Interface) and any web browser.

2-6 Installing Your Ethernet Direct Switch
Unpack the HMG-1648P or HMG-1648EP from the packing box. Please refer to Package Checklist section to
see if any item is missing or damaged. The installation steps include:
Mounting The Switch
Wiring The Power Inputs
Wiring The Alarm Relay
Wiring the Earth Ground
Ethernet Cabling.
2-6.1 Mounting The Switch
There are two types of mounting options: DIN-Rail mounting or wall mounting (need to purchase optional wall
mounting accessories). Users can choose the most suitable mounting installation for your own onsite
applications.
2-6.1.1 DIN-Rail Mounting or Wall Mounting
The DIN-Rail mounting kit is come with the box; please check the Package Checklist section for its
contents.
To attach the DIN-Rail or Wall mounting kit:
1. Screw the DIN-Rail or Wall Mount kit to the position shown in the figure below.
2. To detach DIN-Rail or Wall Mount kit from the switch, reverse the step 1.

2-6.2 Wiring The Power Input
A removable terminal block on the top panel provides both power and alarm connections. This switch supports
dual input from two different DC power sources so that in the event of a single source failure, the switch will
continue to function normally.

Hardware Installation
HMG-1648P & HMG-1648EP Hardware & Installtion 2-6
The two power connections are shown in the above graphic. The device has clearly printed on the case the
locations of the two power inputs, their DC polarity as well as the alarm connection.
2-6.3 Wiring The Alarm Relay
The single electrical relay can be wired into an alarm circuit and under normal condition it is connected as
Normally Closed (will open upon alarm condition). The alarm conditions include power failure, port link up/down
and are user configurable through web user interface. See Alarm Configuration in SNMP for more information
on configuring alarm relay and triggering fault events.
Please note that the alarm relay contact can only support 1A current at 24VDC (1A@24VDC). Do not apply
voltage and current that exceed these specifications.
Be sure to disconnect the power cord before installing and/or wiring your switch.
Be sure of the maximum possible current when wiring connections. If the current goes above the
maximum ratings, the wire could overheat and result in serious damage to your switch.
The acceptable wire range is 12 to 24 AWG.
2-6.4 Wiring the Earth Ground
An earth ground connector is provided on the top panel with an earth ground sign next to it. Grounding the device
can help to release leakage of electricity to the earth safely so as to reduce injuries from electromagnetic
interference (EMI).
Prior to connecting to the power, it is important to connect the ground wire to the earth. Follow steps below to
install ground wire:
1. Loosen or remove the grounding screw.
2. Attach the grounding screw to the ring-type or fork-type terminal of the grounding cable. Make sure that the
grounding cable is long enough to reach the earth.
3. Use a screwdriver to fasten the grounding screw.

HMG-1648P & HMG-1648EP Hardware & Installtion 2-7
2-6.5 Ethernet Cabling
For RJ-45 port connection, prepare twisted-paired, straight through Category 5/5e or above cables for Ethernet
connection. The linking distance between the switch and the network device must be less than 100 meters (328
ft.).
For 10Mbps connections, use 100ΩCategory 3, 4 or 5 cables.
For 100Mbps connections, use 100ΩCategory 5/5e cables.
The UTP port (RJ-45) LED(s) on the switch will light up when the cable is connected with the network device.
Please refer to the LED Indicators section for more information.
Before connecting any network device, make sure network devices support auto MDI/MDI-X.
If not support, use the cross over Category 5/5e cables.
After all wiring and connection are done and the LED lights on the switch’s front panel show normal status, the
hardware installation is complete.

Troubleshooting
Select the proper UTP cables to construct your network. Please check that you are using the
right cables. Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cables for RJ-45
connections: 100ΩCategory 3, 4 or 5 cables for 10Mbps connections and 100ΩCategory
5/5e cables for 100Mbps connections. Also be sure that the length of any twisted-pair
connection does not exceed 100 meters (328 feet).
Diagnostic LED indicators located on the front panel of the switch can help users to easily
monitor the switch.
IF the power indicator does not light on when the power cord is plugged in, you may have a
problem with power cord. Then check for loose power connections, power losses or surges at
power outlet. IF you still cannot resolve the problem, contact your local dealer for assistance.
If the switch LED indicators are normal, the cables are connected correctly, and the packets
still cannot transmit, please check your system’s Ethernet devices’ configuration or status.
