For example, if multiple alarms are present, and these include power supply voltage or hardware alarms, always check their cause before looking at resultant down-stream path failure or path warning (signal) alarms. Similarly, if a path-related failure is indicated (no hardware or software alarms), investigate the path. Go to the WebEML History screen (15 minute view) to check supporting data, such as low RSL and incidence of intermittent pre-failure BER alarms, which if present are evidence of a path-related failure. Check if symptoms match the alarm. Alarms reflect the alarm state, but in exceptional circumstances an alarm may be raised because of a failure to communicate correctly with the alarm source, or a failure in alarm management processing. Always check to see if symptoms match the alarm, using LED indications and the WebEML. Maintenance and Trouble-clearing 3DB18809AAAA Issue 1 915/980

19 Check if recent work may be a cause. Recent work at the site may be a cause or contributing factor. Check for a configuration change, software upgrade, power recycling (reboot), or other site work: Many hardware alarms are only initiated as a loss-of-communications alarm during a reboot, software upgrade, or reconfiguration. By not being able to communicate with the Core-E, their settings cannot be loaded. The fault may be at the hardware device (most likely), communications to it, or the Core-E. Hardware/software compatibility alarms will be raised when a new plug-in is installed that needs a later version of 9500 MPR-E software. Hardware incompatible alarms will be raised when a plug-in is installed in a slot that has been configured for a different plug-in. MSS before an ODU. If there is doubt about whether a fault is in the MSS or ODU, always replace the MSS first; it is quicker and easier. Hot-pluggable. MSS cards are hot-pluggable. There is no need to power-down before replacing, but traffic will be lost unless the plug-in is protected. Plug-in restoration time. Ensure adequate time is allowed for services to resume when a plug-in is replaced Troubleshooting Path Problems A path-related problem, with the exception of interference, is characterized by traffic being similarly affected in both directions. Generally, if you are experiencing only a one-way problem, it is not a path problem. Note A path extends from ODU antenna port to ODU antenna port. Normally a path problem is signalled by a reduced RSL, and depending on its severity, a high BER. Only in worst case situations, such as an antenna knocked out of alignment, will a path fail completely, and stay that way. For weather-related problems, such as rain or ducting, the path problem will disappear as the weather returns to normal Path Problems on a Commissioned Link A path problem on an existing link, one that has been operating satisfactorily may be caused by: Weather-related path degradation If BER alarms are fleeting/not permanent and RSL returns to its normal, commissioned level after the alarm is cleared, rain, diffraction, or multipath fading is indicated. Rain fade is the likely cause of fade for links 13 GHz and higher. Diffraction and multipath/ducting for links 11 GHz and lower. If these alarms are persistent, there could be a problem with the link design or original installation. 916/980 3DB18809AAAA Issue 1 Maintenance and Trouble-clearing

20 Changed antenna alignment or antenna feed problem If RSLs do not return to commissioned levels after a period of exceptionally strong winds, suspect antenna alignment. Also, check the antenna for physical damage, such as may occur with ice-fall. For a remote-mounted ODU, check its antenna feeder. New path obstruction Where all other parameters check as normal, and the path has potential for it to be obstructed by construction works, view/survey the path for possible new obstructions. Interference from other signal sources Interference usually affects traffic in just one direction. Unlike other path problems, RSL is not affected. If suspected, check for new link installations at, or in the same geographical area, as the affected site. Ultimately, a spectrum analyzer may have to be used to confirm interference, which is not an easy task given the need to connect directly to the antenna port, after removing the ODU Path Problems on a New Link For a new link, potential problems can extend to also include: Incorrect antenna alignment One or both antennas incorrectly aligned. Refer to Installation alignment procedure on CD. Mismatching antenna polarizations Given a typical polarization discrimination of 30 db, for most links it is not possible to capture a signal to begin the antenna alignment process. Incorrect path calculations If the RSLs are too low or too high, antenna alignment is correct, and Tx power settings are correct, check the path calculations used to determine the link performance. A good calculation match is +/ - 2 db. Disagreements in excess of 3 db should be investigated. Reflections Reflection (path cancellation) problems may not have been picked up at the path planning stage, particularly if the survey was a simple line-of-sight. If suspected, resurvey the path.

21 6.4.4 Troubleshooting Configuration Problems Configuration problems should only occur during the setup of a new link, or reconfiguration of an existing link. The more common problems may be broadly categorized as: Compatibility Problems The two alarms that may activate are Configuration Not Supported and SW/HW Incompatible: Configuration Not Supported: The plug-in installed is not enabled or is incorrect for the configuration. SW/HW Incompatible: Typically raised when new hardware is plugged into an existing MSS that has software from an earlier release. To remove the alarm, compatible 9500 MPR-E software is required; install the latest software. Incorrect circuit connections No alarms are activated for incorrect circuit connections. An incorrect assignment means the expected end-to-end circuit connectivity will not happen. Re-check circuit assignments for all nodes carrying the lost circuit(s). Take extra care when configuring ring circuits. Incorrect ID naming and commissioning All traffic-carrying circuits must have a unique flow ID for the cross-connect capability to operate. Incorrect/incompatible trib settings Trib line interface settings incorrect, or line levels incompatible. While no alarm activates for an incorrect setting, its effect may result in line levels being too low (LOS alarm), or too high, resulting in a high BER Troubleshooting Ethernet Problems This section gives general guidance on troubleshooting problems related to the four Ethernet ports on the Core-E Card. The most common Ethernet problems are network and connectivity related and therefore always check the following first: for User and NMS ports, verify link partner capability, provisioning, and connection for Radio ports, verify the cabling between ODU and MSS. In order for the green Link LED to light: 1) Cable must be connected to Ethernet port 2) Ethernet port must be enabled (provisioned Enabled). Applicable for User and NMS ports 3) Speed and mode must be provisioned the same as the link partner. The yellow LED opposite the green on the connector indicates activity only. The flashing yellow LED is not an indicator of signal type or quality. 918/980 3DB18809AAAA Issue 1 Maintenance and Trouble-clearing

22 6.4.6 Troubleshooting TMN Problems This section gives general guidance on troubleshooting TMN problems related to Ethernet port 4 on the Core-E Card. Ethernet port 4 on the Core-E Card can be used to transport SNMP IP data. Troubleshoot port 4 connectivity alarms the same as Ethernet ports 1-3. The most common TMN problems are network related and first alert is normally observed by improper operation at the SNMP master. Always check the following first: Verify master is properly registered in NE to receive traps. Verify SNMP version matches system requirements Verify correct community string and privileges Verify proper network routing. Refer to Table 60. for detail TMN network troubleshooting. Table 60. TMN Network Troubleshooting Problem Possible Cause Possible Solution Unusually slow communication in radio network Unable to operate controls using SNMP Can Read SNMP objects but cannot Write to SNMP objects No traps being received from NE Unable to communicate with the NE through the radio network (unable to ping the NE). Can ping the TMN Interface but cannot communicate with the NE using SNMP, or can only see a few SNMP objects in the NE. 1. Normal network management traffic is saturating the communications channel. 2. Polling radios for PM data or missed alarms too rapidly 3. Multiple remote software downloads in process 4. IP traffic other than network management traffic being routed through radio network To perform control operations, the Manager must be registered as a craft device. 1. There may be too many radios being managed within a single region. Split the radio network management into different regions and backhaul the traffic for each region through separate channels. 2. Poll the radios more slowly. 3. Download to fewer radios at a time. 4. Configure external routers to allow only network management related traffic through the Management network of the radios. Dynamic route updates (OSPF, RIP) may attempt to reroute high speed traffic through the TMN network if a high speed ink fails. Register the Manager as a craft device. Manager registration type can be changed as needed to type ct to allow control operation and then be changed back to nml for normal operation. 1. Incorrect community string 1. Use the correct community string. 2. If the TMN Interface is configured for SNMPv2, the write community string is probably wrong. 1. Manager not registered in NE to receive traps 2. Communication failure in network Possible communication path failure or routing failure within the radio network. If using SNMPv2, using the wrong community string. 2. Use the correct write community string. 1. Register Manager with NE. 2. Check network connectivity. Check redundant network paths and routing. Traceroute (tracert) is useful for locating path or routing faults. Use traceroute (tracert) to help locate for communication path or routing problems. Verify community string or username/ passphrase. Maintenance and Trouble-clearing 3DB18809AAAA Issue 1 919/980

23 6.5 Card Removal and REPLACEMENT The basic rules for installing plug-in cards are as follows: Never install, change or remove a card without first connecting to the shelf with an ESD grounding cable. Failure to do so may cause ESD damage to the cards. Plug-ins must be withdrawn and inserted using their finger-grip fastener/pulls. Never withdraw or insert using attached cable(s). Pulling on the cables may damage the cable, plug-in connector, and/or plug-in card connector attachment. When installing a plug-in, ensure its backplane connector is correctly engaged before applying sufficient pressure to bring the plug-in panel flush with the front panel. Improper alignment can result in damaged pins on the backplane connector and/or damage to the plug-in connector. All slots must be filled with either a peripheral plug-in card or a blank panel. Failure to do so will compromise EMC integrity and cooling air from the fan. 920/980 3DB18809AAAA Issue 1 Maintenance and Trouble-clearing

24 Use extreme caution when connecting or disconnecting the ODU cable on the Modem Card. The shelf battery voltage is present on the center conductor of the connector. When removing or replacing a Modem Card, withdraw the card from the shelf before disconnecting the cable to the ODU. Failure to follow these cautions may cause arcing and/or possible power spikes that could affect traffic on other links installed at the node. Removing an in-service card in an unprotected link will cause loss of traffic. Removing an in-service card in a protected link requires switching the traffic onto the standby (protection) channel. All plug-ins can be removed and installed with power applied. a) Turn off NE power. If the main Core-E Card fails, traffic and platform data will switch to the spare Core-E Card automatically. Do not remove power from the NE during the removal and replacement of the failed main Core-E Card without first reviewing/performing the following procedure: b) Remove failed main Core-E Card. c) Turn on NE power. d) Wait two (2) minutes. e) Install replacement Core-E Card.

25 6.5.1 Core-E Card Removal and Replacement Core-E Protected Radio If the Main Core-E Card in slot 1 fails, traffic/services protection and control platform protection switches to the spare Core-E Card in slot 2. Loopbacks and all other manual operations, such as manual switch, tx mute, will be lost (deactivated). Alarms previously active will be newly detected and reported via notification, with a new time stamp. After the removal of a faulty card, when you re-insert the new card, before re-connecting the Ethernet cables between the Core-E card and other systems, wait that the Core-E card LED STATUS (S) ends its flashing activity. Verify the replacement Core-E Card meets the following compatibility rules: Main Core-E Card (in slot 1) and Spare Core-E Card (in slot 2) must be the same type. Local and far end Core-E Cards must use the same software version, but do not have to be the same type Flash card replacement procedure First case: Core-E Protected 1) Get a spare FLASH CARD with the same sw-package release and license of the Main flash. 2) Remove the faulty FLASH CARD from the main Core-E and insert the spare one. 3) Insert the Core-E with the new FLASH CARD 4) The MIB (MAIN FLASH) will be automatically aligned with the MIB (SPARE FLASH). Second case: Core-E Not Protected (NB) 1) Get a spare FLASH CARD with the same sw-package release and license. 2) Remove the faulty FLASH CARD from the main Core-E and insert the spare one. 3) Insert the Core-E with the new FLASH CARD 4) Carry-out the RESTORE procedure. ATTENTION (caution to avoid complete traffic loss) Do not insert in the system a Flash Card the content of which is unknow. You must be aware that, if a Flash Card with SW information different from that running in the system is inserted as it is, the software download will be automatically carried out from the Flash Card toward the System, thus causing a complete system crash. 922/980 3DB18809AAAA Issue 1 Maintenance and Trouble-clearing

38 7.1.2 Safety EMC EMF ESD norms and cautions to avoid equipment damage Warning: to make sure of the continuity and avoid short circuit, all cables / connectors connections (RJ45, Coaxial, Ethernet, Optical Fiber.. ) made on the field have to be verified and checked with Cable tester. The waterproofness must be also checked. If not yet done, read whole Chapter 1 on page 31: it describes the operations and/or precautions to be observed to safeguard operating personnel during the working phases, and to guarantee equipment safety. Read them with accuracy before to start every action on the equipment Conventions To simplify the description of actions, the following symbols are in use: Symbol used WebEML Meaning Manual action Check/Verify On WebEML Select Select a Menu item Sub Menu item The commissioning operations described in this document are for a radio link between a Station A and a Station B. If the network includes supervision, station A is the one located between the supervisory station and station B (see figure below). Installation and commissioning begin at station A.
