2.1.11 POD-H-STM-8x4
Figure 2-41 POD-H-STM-8x4-DL
Figure 2-42 POD-H-STM-8x4-UL
2.1.11.1 Functions and features
- Programmable sectorization can be supported by using H-STM-8x4.
- Based on programmed sector definition, DL output signals received from H-FEM are combined by each
sector and transferred to H-DTM, or H-HOM.
- Based on programmed sector definition, received UL signals from H-DTM, or H-HOM are distributed and
transferred to H-FEM.
- For each sector, controls Power Ratio for multiple H-FEM with same frequency band to share DL output
power at Remote Unit
- ALC function for DL/UL Path
- To minimize negative effects by unused input/output ports such as the degradation of VSWR or isolation
between ports, the unused ports can be switched into 50 ohm termination by user.
- When any one sector consists of remote unit less than 4, H-STM-8x4 can be connected to H-HOM-L directly
without H-DTM.
In this case, the attenuator in the common path of H-STM-8x8 should add 15dB attenuation using web
based GUI to compensate the loss of H-DTM.

2.1.13 POD-H-CDU
Figure 2-52 POD-H-CDU
2.1.13.1 Functions and features
- Provides cable routing space when RF, optic, DC power, and Ethernet cables are connected between the
modules or units in POD DAS system.
- Has good space efficiency since H-FAU can be installed behind H-CDU
2.1.14 POD-H-FAU
Figure 2-53 POD-H-FAU
2.1.14.1 Functions and features
- Installed right above the H-SRU for dissipating heat comes from the modules installed in POD-H-SRU.
- Good space efficiency since H-FAU can be installed behind H-CDU
- DC Power is provided from FAN port located in the back side of H-SRU
- FAN speed control and FAN on/off is controlled automatically by H-SCM based on the temperature of
modules installed in H-SRU.
- FAN fail alarm is monitored by H-SCM.
2.1.14.2 The rules for installing FAN unit
- When the number of module installed in a POD-H-SRU is less than 5, it doesn’t need the installation of H-
FAU.
- When the number of module installed in a POD-H-SRU is more than 6, It needs the installation of POD-H-
FAU.
We strongly recommend that each module should be installed every other slot in a POD-H-SRU.
- When POD-H-SRUs more than 2 are stacked in one rack, one POD-H-FAU per 2 POD-H-SRU should be
installed regardless of the number of module installed in one POD-H-SRU.
We strongly recommend that each module should be installed with sufficient gap as far as possible
when the modules in a POD-H-SRU are not fully installed.
2.1.14.3 Port
- H-FAU must be connected with FAN port which is located in the back of H-SRU (refer to Figure 2-9) by
provided signal cable.

- Control signal for FAN speed control, DC power and FAN alarm signal are transferred between H-FAU and

Figure 2-54 Remote Unit – 7/5/3 band
2.2.1.1 Functions and features
- Supported frequency band
3_band RU: SMR800, PCS, and 2.6G TDD
5_band RU: 700M, 850M, PCS, AWS, and WCS
7_band RU: 700M, SMR800+850M, PCS, AWS, WCS, and 2.6G TDD

- Increase scalability by supporting expansion RU
Expansion RU is connected with main RU through AUX DL/UL port by using RF cable
Expansion RU can be added, when it needs additional frequency band other than frequency bands
being used in main RU, or additional filter attenuation in the frequency band being used in main RU. In
the latter case, the frequency band which needs additional filter attenuation must be off in main RU
and replaced by the frequency band with strengthened filter attenuation in expansion RU.

Expansion RU - AC type
Expansion RU - DC type
Figure 2-61 Port name for each RU type
Optic port
- Connected to Head-end
- Expansion RU doesn’t need optic port because it is connected to main RU through RF cable.
- LC/APC Female type
- Wavelength: 1310nm for downlink, 1550nm for uplink
Serial port (DEBUG): Used for internal debug
AC or DC power input port
- AC or DC power source is provided into Remote unit through this port.
110V AC, 50~60Hz or DC -48V
CAUTION
Must verify whether remote unit is AC or DC type before connecting input power to AC or DC input port
because AC and DC power input port has same form factor.
It might cause severe damage of remote unit when user connects AC input to DC power input port of DC
type RU or DC input to AC power input port of AC type RU in the wrong way.
User can verify easily whether remote unit is AC or DC type by checking the picture of sticker attached
to the debug window cover when you open it. (refer to Figure 2-61)
Ethernet Port
- Ethernet Port #1
Used as GUI Port to access web-based GUI when expansion RU is not connected
Used for connecting to expansion RU when expansion RU is connected to main RU.
Use GUI port in expansion RU to access web-based GUI when expansion RU is connected
- Ethernet Port #2
Used as GUI Port to access web-based GUI for only expansion RU

3.2.2 Grounding
The grounding terminals are located at the rear of H-PSU, H-DMCU, and H-SRU. They must be grounded properly
before powering on the equipment.
Figure 3-10 Head-end units Grounding
3.2.3 Optic port Cleaning
We recommend that optic connector should be cleaned using a dry optical cleaning swab or tissue in a dry
environment before connecting optic cable. Also, if the expected optic loss is 1.5dB higher than the loss
reported in the Web-GUI, the optic loss should be minimized through cleaning optic connectors.(Figure 3-3)
The unused optic ports are should be covered with a protective dust cap. (Figure 3-4)

3.3 Remote Unit
3.3.1 Wall Mount for 3/5/7 band RU and PS700/800 RU
Wall mounting procedure
- Check the suitability of the wall-mounting kit and the wall based on Figure 3-5
Figure 3-5 3/5/7 band RU, PS700/800 RU – wall mount bracket
- Install the wall-mounting bracket using 4 x M10 screw anchors (not included**) according to the drilling
layout. Confirm that the bracket is securely fastened to the wall.
** The M10 screw anchors are not included as part of the RU delivery because the suitable type
depends on the on-site conditions such as wall structure and materials. Therefore, use screw anchors
that are appropriate for the mounting surface.
- Install the Remote Unit on the wall-mounting bracket by lifting the RU into place and lowering it down onto
the bracket. The M6 pins must align with the slots in the bracket to support the RU.
Figure 3-6 3/5/7 band RU, PS700/800 RU – Install RU into wall mount bracket
- Fasten the lower section of the Remote Unit to the bracket using a washer and 2 x M6 screws (on both
sides). Slide a washer over each screw and then insert the screw and tighten it securely.

In case of 2.6G supporting TDD system, TDD sync signal generated from H-FEM-L-B should be transferred to RU
to synchronize TDD timing in overall POD DAS system. H-FEM-L-B has 4 TDD sync output port and each TDD sync
port is connected to TS sync port of H-HOM-L to transfer TDD signal over optic cable.

POD DAS System configuration
- H-DMCU : 1ea
- H-PSU: 1ea

- H-FEM: 6ea (H-FEM-L-7, H-FEM-L-C, H-FEM-L-P x2, H-FEM-L-A, H-FEM-L-W)
H-FEM-L-7, H-FEM-L-C, H-FEM-L-A, and H-FEM-L-W can support MIMO configuration by using one H-
FEM-L module because they have two paths in one module.
H-FEM-L-P supports only one path in one module. 2 H-FEM-L-P are needed to support MIMO
configuration for PCS frequency band.

4.1.6 Cable connection between multiple Racks
Figure 4-6 shows how to connect cable and set rack ID for IP setting.
One H-DMCU is able to control and monitor maximum up to 4 racks and one rack can be composed of
maximum 7 H-SRUs and one H-DMCU. All H-PSU, H-SCM, and H-MCM are connected to H-DMCU through 32
Ethernet ports located in front side of H-DMCU.
Rack ID can be set by dip switch in H-PSU.
- Refer to section 2.1.12.7 to figure out how to set Rack ID.
It might need longer RF cable than RF cable with 35”length included in the packaged box for the connection
between racks. In this case, user needs to buy extra cable with longer length in advance. For your information,
RF cable with 60”, and 90” length can be provided by user’s special order.

5.2 Additional Model Names
Each 2-Band and 7-Band RU has several additional models from the basic model. They are identical to basic model except only with blocked RF band(s) by
Factory loaded software and without hardware changing. So Basic model supports up to specified number of bands and additional models supports less number
of bands with several blocked RF band(s).
The table shown in below shows the basic model and additional models which are derived from the basic model.
