![Cellular Specialties, Inc. grants to the purchaser a fully paid license, at no additionalcharge, to copy or otherwise reproduce all or portions of the product documentation. Suchreproduction shall be for the purchasers use only.Important Safety InformationAntennas used for the purpose of radiating signals indoors are limited to a maximum gain of 3 dBi. Theoutdoor antenna used for the purpose of communicating to the wireless infrastructure is limited to 3dBigain, or any combination of gain and loss that equates to 3dB at input. Each antenna must be positionedto observe minimum separation requirements from all users and bystanders. The following guidelinesshould be used when considering separation distances.INDOOR antennas must be placed such that, under normal conditions, personnel cannot come within20 cm (~8.0 in.) from any inside antenna. Adhering to this minimum separation will ensure that theemployee or bystander cannot exceed RF exposures beyond the maximum permissible limit as definedby section 1.1310 i.e. limits for General Population/Uncontrolled Exposure.OUTDOOR antenna must be positioned such that, under normal conditions, personnel cannot approachcloser than 120 cm. (~4 ft.). A non- directional antenna having a maximum gain of 3 dBi is used,precautions should be taken to prevent personnel from routinely passing closer than specified.This device complies with Part 15 of the FCC Rules.

![-12-Section 3Hardware OperationsTest Point Locations and ValuesIndicator LightsThe CSI repeater, CS12-557-437, by design, has no external test points. The Power and Filter modules aresealed with no user serviceable parts inside. The Ethernet/FAN Module had no user serviceable parts, iffans are observed to fail the module can be sent back to CSI for evaluation. Testing and configuration isdone exclusively by interfacing the repeater with a laptop or desktop computer and using the Web basedGUI or the TMI. Both user interfaces will provide a complete status of the repeater. In most cases if allother components of the system prove to be working properly and the repeater is not, the user will needto return the unit to CSI for inspection and repair. See the Warranty and Repair Procedures in Section 3 ofthis manual.If the covers for the Power and or Filter modules are removed by the user the warranty will be void andthe cost of any needed repair will be the responsibility of the user.This repeater was designed with only two external indicator lights. Both are approximately 3/4”diameter LEDs. The first is located on the Filter Module face plate, between the COM and POWER INports, and is labeled POWER/FAULT. This LED glows red as the repeater is powered up. When the unitcompletes all of it’s bootup procedures the LED will change color and glow green to indicate thesystem is operating normally. If the LED remains red it’s an indication of a problem and the user willneed to check the system status using the Web based GUI or the TMI.The second LED is located on the faceplate of the Power Module, between the DC IN and POWER OUTconnector ports. This light is designed only to show that the unit has DC current and will glow greenwhen the unit is powered.TroubleshootingAll cables should be checked for shorts and opens.The rooftop antenna (Donor Antenna), should be checked for damage.The DAS antennas should be checked for damage.If cables and antennas are acceptable and the problem persists, check repeater status using the Webbased GUI or the TMI. See Alarm/Action Matrix on the next page.Should the repeater fail, or if service is lost and the cause can not be determined from the steps above, the usershould contact CSI Technical Support @ 1.877.844.4274. CSI will remotely access the repeater and advise therespondent of next step(s).](https://usermanual.wiki/Westell/CS12-557-437/User-Guide-1361353-Page-12.png)

![-19 -Software OperationsSection 4General Operation OverviewWeb based GUI SessionPrimary access to the repeater is gained using a LAN connection and a web browser program such as Firefox byMozilla, or Internet Explorer from Microsoft. The repeater ships by default with a DHCP static IP address 192.168.1.102. *If connecting directly to the repeater from a laptop or PC with a crossover CAT-5E cable or over a LAN the user types theIP address of the repeater into the browser address line to connect. When connection is made the user will be promptedfor a user name and password. For the purpose of the GUI session, the default user name is webuser and the pass-word is csi1234. This can also be changed as required. Internet access is not required to use the GUI. (Note: If you areconnecting using a laptop, verify that your Ethernet port is powered. Some laptops will not allow Ethernet connectionwhen on battery power. If this is the case with the laptop you are using you will need to plug it in or update the powersettings.)*DHCP is a protocol that allows computers on a network to be automatically configured appropriately for that network.Networks provide DHCP service by maintaining one or more servers that listen for special broadcasts on the network,called DHCP requests. These requests are made by computers when they first join a particular network. The DHCPserver replies with configuration information that the requester uses to join the network.In the case of this repeater, the unit is configured to with a static address by default. This means it will not request orissue DHCP address and is unlike the PCS verion which is configures as a DHCP Server. This means that a computerconfigured to make a DHCP request on joining a network (most laptops are set up this way) will automatically receive aconfiguration from the PCS repeater when it is connected to it via the local network port. This connection is made witheither a crossover cable or an Ethernet switch or hub.](https://usermanual.wiki/Westell/CS12-557-437/User-Guide-1361353-Page-19.png)
