This document provides module replacement information for the Host Unit II, NEBS Level 3 Host Unit, and the
Host Expansion Unit. The term “Host Unit” refers to both of the Host Unit chassis types; should there be any
differences in how the module replacement is handled between the two Host Units and/or an HEU, those
differences will be clearly identified.
There are several FlexWave Element Management System (EMS) Software Releases active at customer sites.
This guide describes the FlexWave Software Release 9.0.x. If the Host Unit or HEU that you are working on is
running an earlier FlexWave Software Release, refer to the corresponding FlexWave EMS user manual for
comparable information.

SAFELY WORKING WITH FLEXWAVE HARDWARE
Thefollowingsectionsprovideimportantinformationthatyoushouldreadandknowbeforeworkingwithany
FlexWavehardware.Observeallcautionsandwarningslistedinthissection.
SAFETY PRECAUTIONS FOR THE HOST UNIT II, NEBS LEVEL 3 HOST UNIT, AND HEU
SAFETY PRECAUTIONS FOR OPTICAL FIBER
Host Units and HEUs are restricted access equipment and only qualified service personnel should service and
operate this equipment using appropriate tools.
The NEBS Level 3 Host Unit is not suitable for installation as part of a Common Bonding Network (CBN) or an
Isolated Bonding Network (IBN).
The intra-building port(s) of the equipment or subassembly is suitable for connection to intra-building or
unexposed wiring or cabling only. The intra-building port(s) of the equipment or subassembly MUST NOT be
metallically connected to interfaces that connect to the OSP or its wiring. These interfaces are designed for use
as intra-building interfaces only (Type 2 or Type 4 ports as described in GR-1089) and require isolation from
the exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect
these interfaces metallically to OSP wiring.
The maximum ambient operating temperature for the Host Unit is 50º C (122º F).
Wet conditions increase the potential for receiving an electrical shock when installing or using electrically
powered equipment. To prevent electrical shock, never install or use electrical equipment in a wet location or
during a lightning storm.
When loading the Host Unit or HEU in an equipment rack, make sure the mechanical loading of the rack is even
to avoid a hazardous condition such as an unbalanced rack.
The equipment rack in which the Host Unit or HEU is installed should safely support the combined weight of
all the equipment it holds.
This equipment uses a Class 1 Laser according to FDA/CDRH rules. Laser radiation can seriously damage the
retina of the eye. Do not look into the ends of any optical fiber. Do not look directly into the optical transceiver
of any digital unit or exposure to laser radiation may result. Use an optical power meter to verify active fibers.
To avoid the potential of dangerous amounts of radiation exposure, immediately place a protective cap or
hood over any radiating transceiver or optical fiber connector. This practice also prevents dirt particles from
entering the adapter or connector.
You must clean the SFP optical ports at the Host Unit and at the Remote Unit, and clean the tip of the fiber-
patch cords. Failure to clean the ports and cord tips may result in an optical RX or TX alarm state.
Improper handling can damage fiber optic cables. Always allow sufficient fiber length to permit routing of
patch cords and pigtails without severe bends. Do not bend fiber optic cable more sharply than the minimum
recommended bend radius specified by the cable manufacturer. Do not apply more pulling force to the cable
than specified.

GUARD AGAINST DAMAGE FROM ELECTRO-STATIC DISCHARGE
COMPLIANCE
1Notice:Forinstallations,whichhavetocomplywithFCCRFexposurerequirements,theantennaselection
andinstallationmustbecompletedinawaytoensurecompliancewiththoseFCCrequirements.Depending
ontheRFfrequency,ratedoutputpower,antennagain,andthelossbetweentherepeaterandantenna,the
minimumdistanceDtobemaintainedbetweentheantennalocationandhumanbeingsiscalculated
accordingtothisformula:
where
•P(mW)istheradiatedpowerattheantenna,i.e.themax.ratedrepeateroutputpowerinadditiontothe
antennagainminusthelossbetweentherepeaterandtheantenna.
•PD(mW/cm²)istheallowedPowerDensitylimitacc.to47CFR1.1310(B)forgeneralpopulation/
uncontrolledexposureswhichis
–f(MHz)/1500forfrequenciesfrom300MHzto1500MHz
–1forfrequenciesfrom1500MHzto100,000MHz
RFexposurecompliancemayneedtobeaddressedatthetimeoflicensing,asrequiredbytheresponsible
FCCBureau(s),includingantennaco-locationrequirementsof1.1307(b)(3).
2Notice:ForinstallationswhichhavetocomplywithEuropeanEN50385exposurecompliancerequirements,
thefollowingPowerDensitylimits/guidelines(mW/cm²)accordingtoICNIRParevalid:

•F(MHz)/2000forfrequenciesfrom400MHzto2GHz
•1forfrequenciesfrom2GHzto300GHz
3Notice:Installationofthisequipmentisinfullresponsibilityoftheinstaller,whohasalsotheresponsibility,
thatcablesandcouplersarecalculatedintothemaximumgainoftheantennas,sothatthisvalue,whichis
filedintheFCCGrantandcanberequestedfromtheFCCdatabase,isnotexceeded.Theindustrialboosters
areshippedonlyasanakedboosterwithoutanyinstallationdevicesorantennasasitneedsforprofessional
installation.
Electro-Static Discharge (ESD) can damage electronic components. To prevent ESD damage, always wear an
ESD wrist strap when working on the Host Unit and when handling any of its components. Connect the ground
wire on the ESD wrist strap to an earth ground source before touching the Host Unit or any of its components.
Wear the wrist strap the entire time that you work with the Host Unit and its components.
Place modules in anti-static packing material when transporting or storing them.

Replacing the SeRF II Module
REPLACING THE SERF II MODULE
Ittakes46steps,whichhavebeendividedinto11sectionsinthisuserdocument,toreplacetheSeRFIIModule—
followthestepsintheorderpresented.Observeallcautionsandwarningslistedin"SafelyWorkingwith

SERF II MODULE REPLACEMENT PART 1: BACKUP THE CURRENT SYSTEM
CONFIGURATION
TheBackuppageintheFlexWaveElementManagementSystem(EMS)allowsyoutobackupthesystem
configuration.Youusethebackupfiletorestoretheconfigurationasdescribedin"SeRFIIModuleReplacement
Part9:RestoretheSystemConfiguration”onpage 17.
The entire system configuration is stored on the Compact Flash card on the SeRF II Module. Removing the SeRF
II Module disables the Host Unit and interrupts service. You may want to replace the SeRF II Module during a
scheduled maintenance window. If you replace the SeRF II Module with a new one, the system will NOT be
operational immediately following replacement.
Do not power on or off the Host Unit or HEU until directed to do so.
In the unlikely event the system backup function fails, the Compact Flash (CF) will revert to its original factory
settings, and you will need to reconfigure the FlexWave system. Should the backup fail and the CF revert to its
default settings, follow the steps in the FlexWave Software Release 9.0 System Provisioning Guide. (If the Host
Unit or HEU that you are working on is running an earlier FlexWave Software Release, refer to the
corresponding FlexWave EMS user manual for comparable information.)
A system backup can only be performed by a user logged in as admin or by a user with Network Manager
rights.
