Note: The extra length of the RPS and XPIC cables must be bound by using tie-raps, either on the pole or on the other cables coming from the ODUs.
Installing the “Flextwist” waveguide (non integrated antenna)
Concerning the interface between the MPT-HC V2/MPT-XP output flange and the suggested
antenna flange, Table 88 details for each product the standard wave guide to be used and the
suggested flange for the external antenna.
Note: the use of 600 mm flex twist is not suggested for antennas bigger than 3ft (90 cm diameter), due to mechanical reasons. The suggested way to make the RF connection is to use the elliptical wave guide fitted with flanged connectors.

If the FLEX–TWIST is not provided by Alcatel-Lucent, the user must carefully choose the type of the connection guide in order to limit as much as possible galvanic couples between ANTENNA/flex–twist and flex–twist/MPT-HC V2/MPT-XP/9558HC contact surfaces that can induce rust. For this purpose, please note that the surfaces are:
→ chromium-plated at MPT-HC V2/MPT-XP/9558HC output flange side

Installation
→ tin-plated at flex-twist’s flange side
MPT-HC V2/MPT-XP/9558HC system grounding
Each MPT-HC V2/MPT-XP/9558HC transceiver must be individually grounded.
Note: Neither the RF coupler, nor the antennas, integrated or not integrated, should be grounded.
The following items are necessary for the individual grounding of each MPT-HC V2/
MPT-XP/9558HC transceiver:
• one MPT-HC V2/MPT-XP/9558HC Grounding cable 16 mm2 (P/N
1AC001060084).
This 16 mm2 cable must be cut on site and connected to the terminal provided on the
MPT-HC V2/MPT-XP/9558HC transceiver, and, on the other side, to the nearest grounding plate;
This example figure shows the grounding connector position.
Figure 323: Grounding connector example
MPR-e
Connect all grounding cables to the nearest grounding plate, as shown in this example:
377
Hardware installation
Figure 324: Grounding cables connected to grounding plate
Cable grounding
The Power Supply cable and the Ethernet electrical cable must be grounded by using the dedicated Grounding kits.
For ground kit installation instructions refer to the guide provided with each kit.
For tower/mast installations the cables must be grounded at:
• The point where it comes on to the tower from the MPT-HC V2/MPT-XP/9558HC
• The point where it leaves the tower to go to the equipment building
• Maximum distance between the grounding kits: 50 m
• A point just prior to building entry
Figure 325 shows typical tower locations for cable grounding.
Note: All the cables (coax cable, Cat5e cable, fiber cable) must be fixed to the tower with the relevant ties.
At non-standard installations, such as building tops or the sides of buildings, follow the same general guidelines but where proper grounding points are not provided these must first be installed.

Type N connectors and grounding kits waterproofing on the IDU/
ODU cables
Warning: To make sure of the continuity and avoid short circuit, all cables / connectors connections such as RJ45, Coaxial, Ethernet, or Optical Fiber made in the field have to be verified and checked with Cable tester. The waterproofness must be also checked.
For installation on the type N to RJ-45 adapters and grounding kits, refer to the installation notice provided with the connector and the grounding kit.
IMPORTANT:
MPR-e 379
Hardware installation
To prevent potential problems Alcatel-Lucent recommends that particular attention be paid to waterproofing the connection.
To ensure that the connection will hold in bad weather, remember the waterproofing at the end of the operation with the Self auto-amalgamating + UV protection vinyl tape by necklaces Colson / Tie raps at every extremity.
For the assembly between the cable, grounding kit and ODU outdoors, Alcatel-Lucent recommends that you waterproof the cables. Use the Self auto-amalgamating (several turns) to assure the waterproofing. Then cover the set with UV protection vinyl tape to cover the self-amalgamating and end with a necklaces Colson / Tie raps.

Types of MPT-MC
The MPT-MC consists of one or two cabinets including the Ethernet interface + modem + RF transceiver + branching of a channel.
Two mechanical solutions are adopted:
• with embedded diplexer for cost optimisation, shown in
branching (diplexer) is internal to the MPT-MC cabinet; this type of MPT-MC is identified by one Logistical Item only;
• with external diplexer: due to a high number of shifters, the diplexer is external for the flexibility of the shifter customization, shown in
composed by two independent units: the branching assembly (containing the diplexer) and the RF transceiver assembly (containing the RF section); each of this type of MPT-MC is identified by two Logistical Items, one for the branching assembly and another for the RF transceiver assembly. To read the branching assembly identification label it is necessary to separate the branching assembly from the RF transceiver assembly.

Additional operative information on MPT-MC with external diplexer
MPT-MC composition
As shown in
Figure 333 , the MPT-MC assembly is made up of two boxes, one for diplexer
system (branching) and the other for the all other active functions (transceiver) connected together to form the MPT-MC.
An O-RING present in the transceiver box guarantees the MPT-MC assembly waterproofness.
Note: This is a conductive O-RING and must be left dry. Do not wet it with silicon grease
(silicon grease must be used only on O-ring between MPT-MC and antenna).

MPR-e
Warning: A waterproofness tape is glued on the waveguide of the MPT-MC. It must never be removed.
387
Hardware installation
Warning: This gasket must never be removed.
The transceiver box performs all the functions, but does not include the diplexer system.
The branching box provides the interface between the pole mounting/antenna and the transceiver.
The favorite solution foresees the possibility to change in field a spare part transceiver without disconnecting the branching box from the pole mounting/antenna. The transceiver and branching boxes fixing and unfixing are obtained through the four levers.
Transceiver and branching boxes coupling
Figure 334 below shows the transceiver and branching boxes coupling surfaces:
• (A) branching box label informative content described in
• (B) (High Freq) and (C) (Low Freq) RF interfaces on branching box
• (D) (TX) and (E) (RX) RF interfaces on transceiver box
The transceiver and branching boxes can be coupled in two alternative ways (180°-rotated with respect to each other):
• branching box (B) (High Freq) coupled to transceiver box’s (D) (TX)
In this case, the TX part of the transceiver uses the high frequency range of the Shifter set by the Craft Terminal (see
Figure 336 ); the RX part of the transceiver uses the
corresponding LOW frequency range;
• branching box (C) (Low Freq) coupled to transceiver box’s (D) (TX)
In this case, the TX part of the transceiver uses the LOW frequency range of the
Shifter set by the Craft Terminal (see
Figure 336 ); the RX part of the transceiver uses
the corresponding high frequency range.

Power injector
The following considerations apply when using a power injector:
• Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature
(Tma) specified by the manufacturer.
• Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.
• Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
• Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on over current protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
• Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained.
• Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips).
402 MPR-e
Installation
Power injector box
The installation in 19” rack is shown in
Note: Disconnect all power supply cords before servicing.
The Power Injector box must be first installed on the bracket (3DB77008ACXX) by using the screws provided with the bracket, and then the assembly must be installed on the rack.
Figure 352: Power injector box + bracket 3DB77008ACXX
For the installation in 21” rack the 21” Adapter kit (3CC50065AAAA) must be added to each
19” installation configuration.
Power injector box grounding
The assembly must be grounded by using the ground screw present on the bracket, as shown
.
The section cable (wire) is 6 mm² (9AWG) (Yellow/Green).

Grounding
The subrack must be grounded using the ground screw present on the front panel of the bracket on the right side.
The section cable (wire) to use must be a 6 mm² (9AWG) (Yellow/Green).
The subrack-mounting item adds a good electrical connection to rack ground.
MPT extended power unit
With the MPT Extended Power Unit, the interconnection with the MPT-XP can be made with electrical Ethernet cable for cable run lengths less than 100 m by using the PFoE solution
(Ethernet traffic and Power Supply on the same cable). The MPT Extended Power Unit combines Power with the data to implement the PFoE solution.
One cable, interconnects the MPT Extended Power Unit with the MPT-XP (the PFoE cable to be connected to the DC+ODU Data connector of the MPT Extended Power Unit and
Ethernet cable to be connected to the DC+Data connector of the MPT-XP). A second cable interconnects the MPT Extended Power Unit IDU Data connector with the electrical Ethernet connector.
To prepare and to terminate the “Ethernet data + Power Supply” cable (to be connected to
MPT Extended Power Unit and to the DC+Data connector of the MPT-XP) follow the
instructions given in To terminate the Ethernet cable (MPT-HC V2/MPT-MC/MPT-XP/
9558HC side) and to pull it up from Indoor to MPT-HC V2/MPT-MC/MPT-XP/9558HC .
The R2CT connector used to terminate the cable (MPT-XP side) must be provided.
When optical cable is used to transport the Ethernet traffic to the MPT-XP, the MPT
Extended Power Unit provides power to the MPT-XP using coax cable connected to the Type
N DC connector on the MPT Extended Power Unit.

Preparation
Warning: to make sure of the continuity and avoid short circuit, all cables / connectors connections such as RJ45, Coaxial, Ethernet, or Optical Fiber made in the field have to be verified and checked with Cable tester. The waterproofness must be also checked.
Before aligning antennas, verify the following:
• The ODUs are powered up at both ends of the link.
• Transmit and receive frequencies are correctly set.
• Transmit powers are correctly set and transmit mute is turned off.
Note: If frequency and/or power settings are not correct for the application, interference may be caused to other links in the same geographical area.
Signal measurement
Two receive signal-strength indicators are provided to assist antenna alignment, RSL in the
Performance screen, and the RSSI voltage at LEMO connector on the MPT-HC V2/MPT-
MC/MPT-XP/9558HC. Refer to:
•
•
Using the RSSI voltage at the MPT-HC V2/MPT-MC/MPT-XP/9558HC
•
Using RSL data
As the MCT is accessed via connection to the Ethernet generic device, a separate means of communication such as two-way radio or cell phone is required between the operator and the person at the antenna.
418 MPR-e
Installation
To align using RSL:
• Monitor RSL in the MCT Performance screen.
• Set antenna alignment for maximum RSL.
• Repeat for the far end of the link.
• Compare actual RSLs with the expected RSLs from the link installation datapack.
RSL measurement accuracies:
→ ± 2 dB for levels -40 to -70 dBm, over a temperature range of 0 to +35°C.
→ ±4 dB for levels -25 to -85 dBm, over an extended -33 to +55°C range.
Using the RSSI voltage at the MPT-HC V2/MPT-MC/MPT-XP/9558HC
A voltmeter, such as a multimeter, is used to measure RSSI voltage.
Use the MPT Service Cord for the power monitoring in addition to a voltmeter.
• Connect a voltmeter to the MPT-HC V2/MPT-MC/MPT-XP/9558HC through the
MPT Service Cord.
• Adjust antenna alignment until the voltage reading is at maximum value.
• Repeat for the far end of the link.
Check and record the peak voltage at each end. The RSSI voltage provides a direct relationship with RSL, as follows:

Connector usage:
• (M1) LEMO connector, to be plugged into LEMO connector on MPT-HC V2/MPT-
MC/MPT-XP.
• banana plugs (M3) and (M4): output is a 0 to +5V DC voltage proportional to the radio Rx field. During equipment line–up, through a multi–meter it is possible to easily point the antenna until the measured voltage is the maximum, corresponding to the maximum radio Rx field.
• (M2) RJ45 connector, to connect the WebEML directly to the MPT.

RSL measurement guidelines
RSSI/RSL accuracy
When checking RSSI/RSL against the predicted link values ensure appropriate allowances are made for Tx power-setting accuracy, path-loss calculation accuracy, and RSSI/RSL measurement accuracy.
• For a worst-case the overall accuracy is the sum of the individual accuracy limits, which for a link would be ±4 dB of the predicted value (±2 dB for transmit, ±2 dB for receive, 0 to 35°C), aside from the path-loss calculation accuracy, which should be within limits of ±3 dB.
• Typically, where the measured RSSI/RSL is more than 4 dB lower than the expected receive level you should check the path survey results, path calculations and antenna alignment.
Note: When checking RSSI/RSL ensure the measurement is made under normal, unfaded and interference-free path conditions.
• A discrepancy of 20 dB or greater between the measured and calculated RSSI/ RSLs suggests an antenna is aligned on a side lobe, or there is a polarization mismatch.
Note: Without any received signal (Tx mute on the remote MPT for example), the RSL value displayed may be more than -100dBm. This depends of the channelisation/modulation settings
Aligning the antenna
Antenna alignment involves adjusting the direction of each antenna until the received signal strength reaches its maximum level at each end of the link. Fine adjustment for azimuth
(horizontal angle) and elevation (vertical angle) is built into each antenna mount.
Adjustment procedures will be provided with each antenna.If the horizontal adjuster does not provide sufficient range to locate the main beam, the antenna mounting brackets will need to be loosened and the antenna swiveled on its pole mount to locate the beam.
Before doing this ensure the horizontal adjuster is set for mid-travel.
Some mounts for larger antennas have a separately clamped swivel base to allow the loosened antenna to swivel on it without fear of slippage down the pole. Where such a mount is not provided, a temporary swivel clamp can often be provided using a pair of pipe brackets bolted together immediately below the antenna mount.
MPR-e 421
Hardware installation
Note: Ensure antennas are aligned on the main beam, and not a side lobe.
For guidance, see the sections
Verify that ATPC is turned off during the alignment procedure.
Standard alignment procedure
To align an antenna:
• Loosen the azimuth adjuster on the antenna mount (horizontal angle) and adjust azimuth position for maximum signal strength. Ensure antennas are aligned on the main beam, and not a side lobe.
• Tighten the azimuth securing mechanism. Ensure signal strength does not drop as it is tightened.
• Loosen the elevation adjuster (vertical angle) and adjust for maximum signal strength. Ensure antennas are aligned on the main beam, and not a side lobe.
• Tighten the elevation securing mechanism. Ensure signal strength does not drop as it is tightened. The terminal is now aligned and ready to carry operational traffic.
• Record RSL and/or RSSI voltage in the commissioning log.
Additional procedure for CCDP XPIC links with MPT-HC V2/MPT-XP
Note: Procedures are provided for the alignment of dual polarized antennas, and for protected XPIC links.
For CCDP (Co-channel Dual Polarized) XPIC (Cross Polarized Interference Cancellation) links it is important that antenna feeds are correctly aligned to achieve optimum XPIC performance.
While a dual-feed antenna may be specified with a cross polarization discrimination of 30 dB, unless the antenna-to-antenna alignment over a link is correct, the effective discrimination can be significantly less.
• The horizontal-to-vertical receive signal discrimination for satisfactory XPIC operation must not be less than 25 dB, and where possible should be set for optimum discrimination using this procedure.
422 MPR-e
Installation
• High performance shielded antennas typically exhibit 30 dB cross polarization discrimination whereas 40 dB is typical for purpose-designed, high polarization discrimination antennas.
• The received-signal V and H discrimination can be checked using the Radio
Synthesis tab-panel of the MPT-HC V2/MPT-XP/9558HC, as shown in Figure 357 .
Figure 357: XPD measurement
The cross pole discrimination measures the V and H signal discrimination in dB at the input to the MPT-HC V2/MPT-XP/9558HC (from the antenna feeds). The improvement in signal discrimination provided by the XPIC function is in addition to this measurement.
Note: This alignment procedure is intended for dual-polarized antennas, but is also generally applicable to installations using separate antennas for V and H planes.
Alignment procedure for dual polarized antenna
The following procedure details steps required to:
• Check and if necessary set feedhead alignment using a spirit level.
• Align the antennas at each end using just one of the feeds, H or V (Standard co-plane antenna alignment).
→ Where the V and H waveguide ports on an antenna are not marked they can be identified by the orientation of the waveguide slots.
→ Where a dual-polarized antenna presents the same orientation on both ports, one should have a straight waveguide feed to the antenna feedhead, the other will include a 90 degree twist or have a straight waveguide feed but with a polarization rotator in the feedhead. Generally the polarization rotator will act on the outer-most waveguide on the feedhead.
MPR-e 423
Hardware installation
→ For convention, if ports are not marked for V and H, it is recommended that the port that has the straight waveguide feed or is connected to the inner-most waveguide at the feedhead is selected as the horizontal antenna feed port. The following graphic of an antenna feedhead assembly illustrates this. The top port is connected to the inner feed on the feedhead, and with the port orientation shown provides a horizontally polarized feed. The lower port has a rotator included in the feedhead to provide a vertical feed.
424
Ensure the same port is selected for vertical at both ends.
Where possible, the same ‘above and below’ relationship of the feed ports should be used at both ends. For example, if at one end the horizontal feed port is located above the vertical port, as in the example above, then the same relationship should be used at the other end.
• Check cross pole discrimination (XPD) in the Measurement tab-panel of the
MPT-HC V2/MPT-XP.
• Optimize alignment of the feed-heads to achieve maximum cross polarization discrimination.
Note: This procedure assumes that the antennas used at each end of the link do comply with their cross-polarization discrimination specification. If in doubt, refer to the antenna supplier.
Procedure:
1. Static feedhead alignment
During antenna installation and before weatherproofing is installed, use a spirit level to check and set exact vertical / horizontal alignment of the feeds. This step should be completed in conjunction with antenna alignment, step 2, to ensure no misalignment of skew angle is introduced during the pan and tilt process.It should be completed before any feedhead weatherproofing is applied, so that a spirit level can be used against the flange to check and set precise physical vertical/horizontal alignment of the feeds: a. Do not rely on antenna markings as these will not be accurate where a mount is not perfectly level. b. Set the spirit level against the flange of the feedhead. Take care that only the flange of the feedhead is measured, so that no error is introduced by any minor misalignment of the mating flexible waveguide flange. See
MPR-e
Figure 358: Checking feedhead flange with a spirit level
Installation
MPR-e c. If not exactly vertical or horizontal, adjust the feedhead skew angle (rotate the feedhead) until correct (spirit level bubble is precisely centered). For a typical feedhead check both flanges for level, using an end point half way between the level points of the two flanges should there be any discrepancy between the two.
2. Align antennas
Align the antennas at both ends using the standard (co-plane) alignment procedure, but using just one of the feeds, V or H. Refer to
Standard alignment procedure .
If major adjustment to the pointing of the antenna is made during this process, recheck the feedhead skew angle.
When correct, proceed to step 3.
3. Check operation and end-end feedhead alignment
Power-up both V and H links and check they are operating normally and are alarmfree. Use the Measurement tab-panel of the MPT-HC V2/MPT-XP to check that:
→ Tx power measurements are within 1 dB (typically). If not check Tx power settings.
→ RSL measurements are within 2 dB. See
Using RSL data for guidance on
measurement accuracy.
→ Links are operating error-free.
Note: Where there is potential for interference from other links in the same geographical area, check by turning the far end transmitter(s) off and measuring the local end RSL on both V and H feeds.
425
Hardware installation
4. Use the cross pole discrimination (XPD) measurement provided in the Measurement tab-panel of the MPT-HC V2/MPT-XP to measure the actual V and H signal discrimination from each antenna.
→ Where measured XPDs are better than 25 dB no further adjustment is needed
→ Where less than 25 dB proceed to the next step.
Caution: It is possible for a spurious XPD figure of about 50 dB to appear in instances where there is major mis-alignment. Note that the raw XPD should never read higher than the XPD specification of the antennas, which for most high performance dual-pol antennas will be between 30 dB to 35 dB.
Note: The alignment procedures listed under steps 1 and 2 should result in a discrimination of better than 25 dB, as measured in the Measurement tab-panel of the MPT-HC V2/
MPT-XP, which is comfortably within the operating limits of XPIC. However, for best results and greater operating margins during fading, feedhead alignment should be optimized using the following procedure.
5. Optimize end-end feedhead alignment
This procedure corrects for any minor rotational alignment between antennas at each end.
One antenna is the reference antenna and its feed-head assembly is not adjusted during this procedure.
Note: Only check/adjust skew angles on one antenna. If both antennas are adjusted and re-adjusted there is potential for progressive misalignment to occur. Select one antenna as the reference antenna. On long hops and where fading is prevalent there is potential for the
V and H plane paths to be affected differently and to therefore exhibit variable crosspolarization discrimination. This alignment procedure must be conducted during periods of known, stable path conditions.
6. Determine which end of the link is to provide the reference antenna, and at the opposite end open the Measurement tab-panel of the MPT-HC V2/MPT-XP for the
V and H.
7. Adjust the feedhead skew angle of the antenna for maximum XPD on both V and H link. If the maximums for each are at (slightly) different angles, adjust for a midpoint.
426 MPR-e
Installation
Note: Ensure that as you adjust the skew angle, the physical antenna alignment does not shift, which would make it necessary to repeat step 2. Check that antenna mounting bolts and azimuth and elevation adjuster locks have been correctly tightened.The maximum points may be quite sharp, rotate the feedhead slowly to ensure they are not missed.
8. Check the XPD on the link at the reference end of the link, which should be within 1 to 2 dB of the measurements at the adjusted end.
9. On completion ensure feedhead bolts are correctly tightened - check that XPDs do not change during tightening.
10. Retain feed-head adjustment data for the commissioning records.
Main beams and side lobes
This section describes:
•
•
Locating the main beam
Ensure the antennas are aligned on the main beam, and not a side lobe.
Once a measurable signal is observed, very small alignment adjustments are required to locate the main beam. For instance, a 1.2m antenna at 23 GHz typically has 0.9° of adjustment from center of main beam to the first null (0.4° to the -3 dB point). Antenna movement across the main beam will result in a rapid rise and fall of signal level. As a guide, 1 degree of beam width is equivalent to moving approximately 1.0 mm around a standard 114 mm (4.5 in.) diameter O/D pipe.
Antennas can be verified as being on main beam (as opposed to a side lobe) by comparing measured receive signal level with the calculated level.
Signal strength readings are usually measurable when at least a main beam at one end and first side lobes at the other are aligned.
The strongest signal occurs at the center of the main beam. The highest first lobe signal is typically 20 - 25 dB less than the main beam signal. When both antennas are aligned for maximum main beam signal strength, the receive signal level should be within 2 dB of the calculated level for the path. This calculated level should be included in the installation datapack for the link.
MPR-e 427
Hardware installation
Figure 359 is an example of a head-on, conceptual view of the beam signal strength, with
concentric rings of side lobe peaks and troughs radiating outward from the main beam.
Figure 359: Indicative head-on signal pattern for a parabolic antenna
Tracking path error
Side lobe signal readings can be confused with main beam readings. This is particularly true for the first side lobe as the signal level at its center is greater than the signal level at the edges of the main beam, and if tracking on an incorrect elevation (or azimuth) a false impression of main beam reception can be obtained. This illustration shows an example of this with a simplified head-on view of an antenna radiation pattern, and tracking paths for three elevation settings.
Figure 360: Example tracking path signals
428 MPR-e
Installation
Line AA represents the azimuth tracking path of a properly aligned antenna.The main beam is at point 2, and the first side lobes at points 1 and 3. Line BB represents the azimuth tracking path with the antenna tilted down slightly. Signal strength readings show only the first side lobe peaks, 4 and 5. In some instances the side lobe peaks are unequal due to antenna characteristics, which can lead to the larger peak being mistaken for the main beam. The correct method for locating the main beam in this case is to set the azimuth position midway between the first side lobe peaks, and then adjust the elevation for maximum signal.
Line CC represents an azimuth tracking path with the antenna tilted down further still. The first side lobe signal peaks (6 and 7) appear as one peak, leading to a mistaken interpretation of a main beam. The correct method for locating the main beam is to set the azimuth at mid peak, between 6 and 7, and then adjust elevation for maximum signal.
This first side lobe peaking is probably the most frequent cause of misalignment in both azimuth and elevation, especially so if one side lobe peaks higher than the other, as shown in
Figure 361 . A common error is to move the antenna left to right along line DD, or top to
bottom along line EE, always ending up with the maximum signal at position 1.

Maintenance and trouble-clearing
Introduction
This section contains information and procedures to aid in restoring the equipment to its proper operating condition after it has been determined that a problem exists.
The following warnings and cautions apply while operating, performance testing, troubleshooting, or repairing the 9500 MPR series radios.
Danger: Short circuits in low-voltage, low-impedance dc circuits can cause severe arcing that may result in burns or eye injury. Remove rings, watches, and other metal jewelry while working with primary circuits.
Exercise caution to avoid shorting power input terminals.
Caution: Units with the electrostatic-sensitive (ESS) symbol contain ESS devices. Store these units in an antistatic container when not in use, and anyone handling a unit should observe antistatic precautions.
Refer to the Special Precautions pages in the front of the instruction book for detailed handling information.
Note: Ensure that all antennas are properly aligned and waveguide is in good physical condition.
Note: Before performing procedures that might in any way affect transmission, it is recommended that the person performing the procedure understand the Rules and
Regulations pertaining to the equipment and be properly authorized to operate the equipment.

Maintenance philosophy
Maintenance philosophy
This section provides information and procedures for equipment maintenance down to the
Card level. Card repair is not covered in this manual.
The use of maintenance procedures in this section may result from failure of a periodic check, an alarm indication, or unacceptable performance.
This document addresses only the MPR-e maintenance. For information about Maintenance on MPR-e directly connected to a 7705 SAR system, see the 7705 SAR documentation. In addition, considering the level of integration between two systems and their joint behavior, maintenance operation must always involve people with knowledge of both MPR-e and the
7705 SAR.
Personal computer (PC)/laptop
Connect the PC to the FE port of the Ethernet generic device.
Troubleshooting
This section provides guidance on:
•
Before going to site checklist
•

•
Relationship between the alarms on the MCT and SNMP traps
•
Before going to site checklist
Where possible, before going to site obtain the following information:
• Does the fault require immediate attention?
• Determine who is the best-placed person to attend the fault.
464 MPR-e
Maintenance and trouble-clearing
• Confirm the nature and severity of the reported fault, its location, MPT type, frequency band, high/low end MPT, capacity modulation and configuration (non protected, protected, diversity). Ask:
→ Is just one link affected, or a number of links in the same geographical area?
→ Is the path down completely or is traffic passing but with a BER alarm?
→ Could the fault be in the equipment connected to MPT, rather than in MPT? Are there alarms on other, connected equipment?
→ Is it a hard or intermittent fault?
→ Do alarms confirm which end of an alarmed link is faulty?
• Could the weather (rain, ice, high wind, temperature) be a factor in the reported fault?
Note: If the fault suggests a rain fade or other weather related fade condition and it matches the prevailing weather conditions, do not take any action until the weather abates.
• Does link history suggest any fault trends?
→ Does the fault history for the link indicate a likely cause?
→ Is the link newly installed?
→ Has there been any recent work done on the link?
• Ensure that you have with you:
→ Appropriate spares. Where an equipment failure is suspected, these should include replacement of the MPR-e. If an MPR-e is suspected then local/national climbing safety requirements must be adhered to.
→ A laptop PC loaded with Craft Terminal, and an Ethernet cable. If an Ethernet connection is to be used, you need the IP address and also the addresses for any remote sites to be accessed.
→ If login security has been enabled, you need the password for the local and also any remote sites to be accessed.
→ Any special test equipment that may be needed, such as a BER tester.
→ Toolkit.
→ Keys for access to the site.
PC troubleshooting
If the NE is not displayed in the NEtO screen, the MCT has to be launched directly through
MctStarter.jar located under the path created by the operator during the local copy and under
\\WebEML MPR TCO R5.0\9500MCT_V08.0X.XX\MctStarter.jar

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.
MPR-e 475
Troubleshooting
Note: A path extends from MPR-e antenna port to MPR-e 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 one of the following:
•
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.
•
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 MPR-e, 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 MPR-e.
476 MPR-e
Maintenance and trouble-clearing
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 Antenna alignment procedure.
•
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.
Equipment removal and replacement
Warning: Never install, change or remove an unit without first connecting to the shelf with an ESD grounding cable. Failure to do so may cause ESD damage to the cards.
MPT-HC V2/MPT-XP/9558HC removal and replacement
Disconnect the cables and connect them to the spare MPT-HC V2/MPT-XP/9558HC.
Note: The MPT-HC V2 can also be used to replace the MPT-HC V1. The 23 GHz MPT-HC
V2 is a Tx High Power version vs. MPT-HC V1. Take in account it when MPT-HC V2 is used as spare of MPT-HC V1.

Cleaning
Replacement of an MPT-HC V2/MPT-XP in XPIC configuration
To replace an MPT-HC V2/MPT-XP in XPIC configuration it is mandatory to follow the following procedure:
1. Power off the MPT-HC V2/MPT-XP
2. Disconnect the XPIC cable
3. Disconnect the RPS cable
4. Uninstall the failed MPT-HC V2/MPT-XP
5. Install the spare MPT-HC V2/MPT-XP
6. Connect the RPS cable
7. Connect the XPIC cable
8. Power on the MPT-HC V2/MPT-XP
MPT-MC removal and replacement
Disconnect the cables and connect them to the spare MPT-MC.
Cleaning
Warning: Do not use acid, alcohol, or brushes to clean the equipment because damage to the silk-screen labeling and antistatic coating can result. Cleaning should be confined to the removal of dust and dirt using a damp cloth.
Cleaning should normally be confined to the removal of dust and dirt using a soft bristled
(natural fiber) brush and a low velocity blower (such as a vacuum cleaner with a plastic blower nozzle). Do not use acid or synthetic bristled brushes to clean cards that contain electrostatic-sensitive components.

Introduction
Warning: at the beginning of this procedure, in an MPR-e standalone configuration, the
“local IP address” and “Ethernet IP address” of both the NE 9500 MPR stations areof each
MPR-e station is still set to default value 10.0.1.2 (as delivered from Alcatel–Lucent factory).
Consequently, their physical connection to the TMN network must be completed after having changed such addresses to correct values.
The commissioning procedure is summarized as follows:
1. Turn up (phase 1)
→ Visual inspection and NE configuration.
a. Station A, roughly point the antenna towards station B (if not done in the
Hardware Installation procedure) b. Commission station A (phase 1) c. Commission station B (phase 1)
