The following precautions apply to the SRU:
• 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.

• 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 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
