2.5 Installation
2.5.1
Installation Requirements
Before and during installation, the following should be carefully verified in order to avoid any
problem:
•
•
•
•
•
•
Faulty Cabling/Connectors: Fiber cable and connectors must be verified prior to plugging
into the SRU
Dirty Connectors and ports
Faulty Small Remote Unite (SRU) components
RF source equipment issue
External RF Interface problem such as antenna port
Wrong or Improper Ethernet cable for POE input
The following guidelines are required when the Headend unit is installed on the 19” rack:
•
•
Locate the equipment with the space for the sufficient airflow to prevent build-up from
the overheating. Do not compromise the amount of airflow required for safe operation of
the equipment.
Verify the power connection and Fiber cables prior to turning on the systems.
WARNING: Equipment loading must be verified prior to mounting the equipment on the wall or 19” rack.
2.5.1.1 General Safety Precautions
The following precautions apply to the SRU:
•
•
•
•
2.5.2
The units have no user-serviceable parts. Faulty or failed units are fully replaceable through
Intelibs.
When the Fiber cable is connected to the equipment, the connectors must be free from the dust
and connected according to the cable manufacturer’s instructions. (WARNING: For the safety,
DO NOT conduct eye-contact at the connector ends of the fibers or the port of the FHU and SRU
unless equipped with protection goggle. Invisible infrared radiation may be present at the front
panel of the RHU, FHU and SRU. Do not remove the fiber port dust caps unless the port is going
to be used. Do not stare directly into a fiber port.)
When the service antenna is connected to the SRU, SMA connector must be firmly tightened.
(Caution: Do NOT over tighten the connector.)
The PoE Ethernet cable should be run with the maximum no more than 300 feet distance. It is
only for in-building use only.

2.5.6 Power cable
SRU uses 12V DC power, and DC power adapter/splitter set using PoE (Power over Ethernet) technology
are provided with the system. The PoE adapter converts AC input to 48V DC, and delivers DC power via
UTP5 Ethernet cable up to 330 feet. The PoE splitter receives 48V DC power via UTP5 Ethernet cable,
and converts 48V to 12V DC. The power connection diagram is described in Figure 2-8.

Power connection sequence is as follows:
①
Connects UPT5 cable to “OUT” port of PoE adapter.
②
Connects UTP5 cable to “IN” port of PoE splitter.
③
Connects one end of power cable to PoE adapter’s AC inlet, and the other side of power cable to
AC outlet.
④
Verify the LED status on PoE splitter and adapter
⑤
Connects DC output connector to “Power” port of SRU.
2.5.7 Optic cable
SRU provides one optic port for uplink, “Optic” port, and optic connector type is FC-APC (Angle Physical
Type). While connecting the optic cable, align the FC type connector at latch and hole position, then plug
in and rotate clockwise tightly.

4. Decrease the DL “USER ATT(①)” to 30dB(Minimum gain) and verify that antenna is
connected at antenna port of SRU properly.
5. Press the “HPA On/Off(②)” button to turn HPA on
6. Monitor the output power level from “ OUT PWR(③)” parameter and tune up “USR ATT(①)”
to set the proper output power level of SRU.
2.6.2
Up Link power setting
1. Use the “ATT(④)” to control Uplink gain.
2. Uplink gain is very important parameter because uplink is connected to RF source of BTS. If
you have wrong uplink gain set BTS receiver sensitivity may be degraded by SRU uplink gain.
3. Try to minimize uplink gain with mobile Tx power.
2.7 Configuration and Maintenance
SRU can be configured in three ways via remote internet connection or local serial port connection.

Click the temperature upper limit box which is on the right side of “TMPUPR”. A number in the
box represents current upper limit of chassis’ temperature.
Step 2
•
Select TMPUPR value by clicking up/down button or enter temperature upper limit. Then click
“Set” button.
•
The result of operation displays at the bottom of the window.
•
Click close button on the upper right corner of the window to exit the command window.

The small color box on the left side of “TMPUPR” represents current status of upper limit of SRU
chassis’ temperature. If the box is GREEN, operating status is in normal condition. If the box is
RED, “TMPUPR” alarm occurred and remains.

About us: Redirect to Intelibs’ web page.
Log Off: Logging off current user’s session.
Before using web interface, followings should be assigned and set correctly:
•
•
•
Master Unit’s IP address
RHU system’s IP address
Master Unit’s IP address on RHU system
Figure 2-16 shows web interface flow over IP network.

If IP network connection is established successfully, then parameters of SRU can be set by Web browser,
and all status information can be reported to Web browser.
Following is one example of Web operation which sets the upper limit of SRU chassis’ temperature.
Step 1
•
Open Web browser such as Internet Explorer or Chrome.

31
•
Enter Master Unit’s IP address that is assigned for Web interface. Usually the IP address is global
IP or private IP if web client is on the same network where Master Unit is.
Step 2
•
Enter Login ID and Password. (Please contact Intelibs for login ID and password)
The web interface provides two level user access, privileged or not. Privileged users can retrieve
and change the advanced parameters that control the DAS system. For example, “TMPUPR”
parameter is an advanced parameter that requires privileged user login.
•
If ID/PWD matches, Web interface goes to Home page.

Step 3
•
Click “DAS systems” menu box to see the Hierarchy view of DAS systems.
Clicking this menu box expands
hierarchical tree view of the registered
DAS systems

Step 4
•
Select a DAS system to control and monitor at the hierarchy view.
Step 5
•
Select “Advanced Mode” check box to display advanced parameters, for example “Chassis High
Temperature Alarm Threshold” in the parameter view panel.

Step 6
•
Enter numbers for “Chassis High Temperature Alarm Threshold”. Then click “Set” button.
Step 7
•
If confirmation window pops up, click “OK” button to confirm changing the parameter value.
•
Then result window will pop up.
The column “Chassis High Temperature Alarm” represents upper limit of SRU chassis’
temperature. If the value box is GREEN, operating status is in normal condition. If the box is
ORANGE, this indicates “TMPUPR” alarm is turned on.

4 Human RF Exposure – Maximum Permissible Exposure Evaluation
The recent FCC developed guideline for evaluation of the human exposure to the RF emissions. The
maximum permission Exposure (MPE) for power density of the transmitter operating RF ranges between
300 KHz and 100 GHz. As the Intelibs SRU belongs to the fixed equipment, Analysis has been conducted
to evaluate the MPE from the distance greater than 20 Cm as the fixed equipment required.
Antenna gain is restricted to 1.5W ERP (2.49 W EIRP) in order to satisfy RF exposure compliance
requirements. If higher than 1.5W ERP, routing MPE evaluation is needed. The antenna should be
installed to provide at least 20 cm from all persons to satisfy MPE requirements of FCC Part 2, 2, 1091.
SRU transmits far below that FCC power density restricts. FCC defines power output limits at 20 cm
distance for various frequency ranges:
•
•
Over 300 MHz to 1.5 GHz the limit is determined by frequency /1500
Above 1.5 GHz the limit is 1 mW/cm^2
The basic equation for determining power density is:
S = PG/4(pie)R^2
Were S is power density, which is mW/Cm^2
PG, the transmitted power from the antenna indentified as EIRP (Equivalent Isotropically Radiated
Power)
R is the distance of interest from the antenna.
Typical Installation Example:
As the typical height of a floor is assumed as 10 foot high, an average person is assumed 6 foot high, the
distance from antenna to body is 4 feet (112 cm).
For PCS 1900 band, the maximum power output per carrier is assumed 23 dBm. With the assumption of
5 dBi antenna is used, PG in the equation is equal to 28 dBm EIRP.
Using S = PG/4pieR^2
S = 0.63/(4*3.14)*112^2 = 4μW
Also worst case with the assumption of minimum distance of 20 cm according to FCC regulation:
S = 0.63/(4*3.14)*20^2 = 0.1mW

whether such stress results from accident, neglect, misuse, lightning, failure of electrical power, air conditioning, humidity control,
transportation, the making of specification or configuration changes requested by Customer, or any other cause other than ordinary
use, and whether or not such stress is the fault of the Customer, (3) has been purchased from another Vendor and is networked,
linked, attached or otherwise intended to work with the System or (4) has been moved from the place of installation. When the
system has been improperly modified, repaired, stressed, used or moved as described above, Intelibs may, at its option and subject
to the approval of the Customer, perform such corrective work, including any repairs, replacements and adjustments, as are in
