General Hazards

The following table describes the general hazards that must be addressed when
planning and installing an Eclipse system.

For more information on health and safety when u sing Aviat Networks products, refer
to Aviat Networks’ Best Practices Guide.

Topic Information

Airflow Requirements Rack installations must be made so the airflow required for safe and

correct operation of Eclipse is not compromised. For the fan-cooled
Eclipse INUs and fan-cooled Eclipse IDUs, unobstructed air passage
must be maintained to each side of the chassis, which requires a
minimum of 50 mm (2 inches) of side spacing to any rack panels,
cable bundles or similar.

Where a Fan Air Filter is installed in an INU it must not be allowed
to become clogged with dust. Replace when necessary.Inspection
must be at not more than 12 monthly intervals when installed in
telecommunications equipment room controlled-air environments.
Otherwise, inspection is required at more frequent intervals.

EMC Eclipse has been tested for and meets EMC Directive

The equipment was tested using screened cable; if any other type
of cable is used, it may violate compliance.

Eclipse is a Class A product. In a domestic environment this product
may cause radio interference in which case the user may be
required to take adequate measures. This equipment is intended to
be used exclusively in telecommunications centers.

ESD ESD (electrostatic discharge) can damage electronic components.

Even if components remain functional, ESD can cause latent
damage that results in premature failure. Always wear proper ESD
grounding straps when changing or handling the plug-in cards and
avoid hand contact with the PCB back-plane and top-plane. Connect
your ESD grounding strap to the combined ESD and ground
connector on the INU rack ear. Spare plug-in cards or cards to be
returned for service must be enclosed in an anti-static bag. When
removing a card from the anti-static bag for installation in an INU,
or placing a card in a bag, do so at the INU and only when
connected to the INU via your ESD grounding strap.

Circuit Overloading When connecting the Eclipse, determine the effect this will have on

the power supply circuit protection devices, and supply wiring.
Check Eclipse power consumption specifications and the supply
capability of the power supply system. This check of capacity must
extend to the dc power supply and not just to an intermediate
connection point.

2004/108/EC.

Eclipse Indoor Unit and
DC Supply Grounding

260-668066-003 Rev 001 August 2010 2-3

The ground for Eclipse indoor unit(s) must be connected directly to
the dc supply system ground conductor, or to a bonding jumper
from a grounding terminal bar, or bus to which the dc supply
system grounding is connected.

Chapter2. Health and Safety

Topic Information

Intrabuilding interfaces
and cabling for NEBS
compliance

Protection from RF
Exposure

Intrabuilding connections to/from Eclipse ports must only be
connected via intrabuilding or unexposed wiring or cabling.

Intrabuilding ports MUST NOT be metallically connected to
interfaces that connect to the OSP or its wiring. These interfaces are
designed for use as intrabuilding interfaces only (Type 2 or Type 4
ports as described in GR-1089-CORE, Issue 4) 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.

Shielded and grounded cables must be used for intrabuilding
cabling to/from Eclipse ports. Cables must be grounded at both
ends.

When installing, servicing or inspecting an antenna always comply
with the following:

• Locate the antenna such that it does not infringe the RF exposure
guidelines for general public. Refer to

• Do not stand in front of or look into an antenna without first
ensuring the associated transmitter or transmitters are switched
off.

• At a multi-antenna site ask the site owner or operator for details
of other radio services active at the site and for their
requirements/recommendations for protection against
potentially harmful exposure to RF radiation.

• When it is not possible to switch transmitters off at a
multi-antenna site and there is potential for exposure to harmful
levels of RF radiation, wear a protective suit.

• Do not look into a waveguide port when the radio is active.

RF Exposure.

Fiber Optic Cables Handle optical fibers with care. Keep them in a safe and secure

location during installation.
Do not attempt to bend them beyond their minimum bend radius.

Considerations

The Eclipse INUs have the +ve pin on their dc power supply
connector connected to chassis ground. It must be used with a

-48 Vdc power supply which has a +ve ground; the power supply
ground conductor is the +ve supply to the radio. For NEBS
compliance the battery return connection is to be treated as a
common DC return (DC-C), as defined in GR-1089-CORE.

• There must be no switching or disconnecting devices in this
ground conductor between the dc power supply and the point of
connection to an Eclipse system.

The Eclipse High Power IRU 600 supports wide-mouth +/-21 to
+/-60 Vdc operation. Both pins on its power supply connector are
isolated from chassis ground. For NEBS compliance the battery
return connection is to be treated as an isolated DC return (DC-I),
as defined in GR-1089-CORE.

The power supply for an Eclipse system must be located in the same
premises as the Eclipse system.

An appropriate power supply disconnect device should be provided
as part of the building installation.

If the Eclipse indoor unit is installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack
environment may be greater than room ambient. The maximum
ambient temperature (Tmra) of +45° Celsius (113° F) applies to
the immediate operating environment of the Eclipse indoor unit,
which, if installed in a rack, is the ambient within the rack.

Restricted Access The Eclipse system must be installed in restricted access sites. The

indoor unit and associated power supply must be installed in
restricted areas, such as dedicated equipment rooms, closets,
cabinets, or the like. Access to the tower and antenna location must
be restricted

Note: For USA:

In restricted access areas install the Eclipse system in accordance
with articles 110-26 and 110-27 of the 2002 National Electrical
Code ANSI/NFPA 70, or to any subsequent update to this code for
the relevant articles.

RF Exposure

To ensure compliance with the FCC RF exposure requirements, a minimum distance of
20 meters must be maintained between the antenna and any persons whilst the unit is
operational. This calculation is based on the maximum conducted power and
maximum antenna gain.

260-668066-003 Rev 001 August 2010 2-5

Chapter2. Health and Safety

• Eclipse with IRU600, 5.8 GHz, has been tested and certified for use with a parabolic
antenna with a maximum gain of 46.8 dBi. Higher gain antennas must not be used.

• The maximum transmit output power on the IRU 600 has been limited to a
maximum of 1W (30dBm) at the antenna port, to comply with the conducted power
limit in FCC CFR 47, Part 15.247.

Routine Inspection and Maintenance

This section overviews required and recommended inspection and maintenance
practices to ensure health and safety of installed equipment is maintained to highest
levels. For more information, refer to the Aviat publication: Best Practices.

Routine Inspections

All sites must be inspected annually, or more frequently if subject to abnormal
operating conditions such as particularly exposed sites, or sites subject to salt-spray or
heavy snow/ice loading over winter months.

The inspection should cover the physical installation including the antenna,
waveguide, equipment grounding, tower and building grounds, weatherproofing, and
general site integrity.

Where a Fan Air Filter is installed in an INU (for NEBS compliance) it must be
inspected annually, or more frequently if the INU is installed in an environment that is
nor controlled for dust exclusion.

Selected ground wires should be resistance checked and then compared with previous
checks to ensure there has been no significant change.

The operational performance of the radio and associated equipment should be checked
against their as-built figures.

Trend Analysis

Use available current and historical Eclipse alarm and performance data to determine
any trend that may lead to a failure - if allowed to continue.

Check for the following trends:

• Reducing receive signal levels

• Gradually increasing bit errors or an increasing errored seconds count

• Changes in transmit power

• Increasing occurrence of other weather related changes in performance

• Increasing occurrence of a particular hardware failure

Time spent in conducting such analysis is time well spent. Catching a problem before
it brings down the network is good network management.

2-6 Aviat Networks

Fault Analysis

All faults, once cleared, should be the subject of a fault report. The data presented in
these reports should be analyzed from time to time to check for any common threads,
which may point to a particular weakness in the design, installation, or maintenance of
the network or to a specific component.

The time taken to restore service and the parts used should also be analyzed to see if
improvements are possible in the maintenance proce dures, main tena nce trainin g and
spares holdings.

Training

Properly trained and experienced planning and installation personnel are essential for
establishing and maintaining high integrity in a new network. Similarly, properly
trained network management and service personnel are essential for the continued
good health of a network.

The training needs for personnel should be reviewed from time-to-time to ensure they
maintain expertise in their area of work, and on the installed base.

Eclipse Installation Manual

Spares

Spares holdings should be reviewed on a regular basis to ensure the correct quantity
and type are held, and held at the most appropriate locations.

Analysis of spares usage will show any trend for excessive use of spares, which may
point to a weakness in the deployment or manufacture of the item.

Spares holdings should also be checked from time to time and if necessary brought up
to the current hardware and/or software revision level.

digital traffic from the backplane or data packet plane and convert it to an IF signal
for connection to an IRU600. The reverse occurs in the receive direction.

• One RAC with one 1+0 IRU 600 is used for a 1+0 link.

• Two RACs with one 1+1 IRU 600 are used for 1+1 or diversity links.

• RACs control TX switching and RX voting on protected / diversity links.

• XPIC (cross polarization interference cancellation) RACs support CCDP
(co-channel dual polarization) operation.

• DACs support the user interface. They take the user traffic and convert it into a

format compatible with the data backplane, where it cross-connects to a RAC or
RACs, or to other DACs.

• Different DACs support DS1, DS3, OC3, and Ethernet connections.

• Multiplexer DACs support transport of OC3 or DS3 with NxDS1 rates.

• Ethernet DACs support a L2 switch function. The GigE DAC GE supports
advanced ring/mesh, link aggregation and VLAN tagging options.

• Most DACs can be protected using a stacked (paired) configuration.

• DS1, DS3, and OC3 DACs support Ethernet-over-TDM options to enable Ethernet
transport over legacy TDM radio or leased-line links.

• AUX (Auxiliary card) supports async or sync service-channel connections, and

alarm I/O options for connection to external devices.

• NCC (Node Controller Card) provides the node management and DC voltage

conversion functions. The NCC is a mandatory card.

• It manages Eclipse operation and event collection and management.

Plug-in Cards Overview

RAC 60

RAC 60 supports DPP (Data Packet Plane) as well as backplane data connections, plus
ACM (Adaptive Coding and Modulation) options.

Four dynamically switched modulation rates are available; QPSK, 16 QAM, 64 QAM,
256 QAM. Modulation switching is errorless for priority traffic.

Coding options additionally provide selection of two modulation states, one for
maximum throughput, the other for maximum gain. These apply on each of the
modulation rates of QPSK to 256 QAM to provide an effective total of eight modulation
states.

• Maximum throughput delivers maximum data throughput - at the expense of some
system gain.

• Maximum gain delivers best system gain - at the expense of some throughput.

• Up to four of the eight modulation states offered with ACM can be selected for use.

A DPP port enables direct routing of Ethernet traffic to a DAC GE.
Individual ACM modulation rates can be set as fixed rates. These are compleme nted by

fixed rates for TDM (DS1, DS3, OC3) capacities.
Channel bandwidths range from 3.5 to 30 MHz.
Air-link capacities for Ethernet, or for Ethernet + DS1, extend to 189 Mbit/s.
Backplane-connected TDM options extend to 100xDS1, 3xDS3, 1xOC3.
Payload encryption is a licensed option.
RAC 60s must be used at both ends of a link, or RAC 60 with a RAC 6X in non-CCDP

mode.

RAC 6X

DAC GE

Eclipse Installation Manual

RAC 6X adds CCDP operation to RAC 60 capabilities. Two RAC 6X cards are operated
as a CCDP pair, either in the same INU, or in separate co-located INUs to provide
double the capacity over one channel using both the horizontal and vertical
polarizations. An XPIC function between the RACs ensures cross-polarization
interference is eliminated.

Chapter 3. System Overview

NCC

The NCC is a mandatory plug-in for an INU/INUe. It performs key node management
and control functions, and provides various dc rails from the -48 Vdc input. It also
incorporates a plug-in flash card, which holds Node configuration and license data.

Power input limits are -40.5 to -60 Vdc. The power connector is a D-Sub M/F 2W2. The
+ve dc return pin is connected to chassis ground.

Figure 3-16. NCC

FAN

The FAN is a mandatory plug-in. There are two variants, 2RU and 1RU. Each is fitted
with two long-life axial fans plus monitoring and control circuits.

• One 1RU FAN is fitted in an INU.

• One 2RU FAN is fitted in the INUe.

Eclipse IRU 600

The IRU 600 is a 3RU rack-mounted transceiver unit for co-location with an INU/
INUe as an all-indoor installation.

IRU 600 is 1+1 optimized with provision for two RFUs (Radio Frequency Unit) and a
companion filter-based ACU (Antenna Coupler Unit).

High power and standard power RFUs are available. Both are highly energy efficient.
(50W power consumption for standard power, 98W for high power).

Transmit power output is limited (applies on the high power RFU) to a maximum of 1W
(30dBm) at the antenna port to comply with the conducted power limit in FCC CFR 47,
Part 15.247.

• Standard power RFUs are powered over the IF cable from its INU/INUe.

• High power RFUs are additionally powered using a separate DC input on the RFU
front panel.

• The power connector (D-Sub M/F 2W2) and cable is identical to that used for the
INU.

• The high power RFU provides a wide-mouth connection for +/- 21 to 60 Vdc. Both
+ve and -ve pins are isolated from ground.

• An integral DC/DC converter provides polarity protection, under/over voltage
shutdown, over-current limit, and thermal shutdown.

• NEBS compliant EMI filtering is included.

There are no serviceable fuses.

Eclipse Installation Manual

The ACU design supports paired and unpaired Tx/Rx frequency splits and incorporates
an optional expansion port to allow other radio links onto its waveguide feed for
co-path operation.

The IRU 600 also supports 1+0 repeater (back-to-back) operation. The links may be in
the same or different bands.

Protected/diversity options include:

• 1+1 hot-standby, single antenna, with equal or unequal split.

• 1+0 hot-standby-ready.

•Space diversity (dual antennas) with common or split Tx.

Chapter 3. System Overview

Protection Options

Eclipse supports link, interface, network, and platform protection options:

Link/Path Protection

Hot-standby, space diversity, frequency diversity, or dual protection options are
available. RACs and their companion IRU 600 are protectable.

Rx voting is hitless/errorless; Tx switching is not hitless. The maximum restoration
time for a Tx switch is 200 ms.

A remote Tx switch is forced in the event of a silent Tx failure.

Interface Protection

DS1, DS3 and OC3 interfaces can be hot-standby protected using paired (stacked)
DACs.

The protectable DACs are DAC 16x V2, DAC 3xDS3, DAC 3xDS3M, DAC 2x155o, DAC
2x155e, DAC 155oM.

When a switch occurs, all Tx and/or Rx tributaries are switched to the protection
partner.

Two protection configurations are supported, tributary protection, and always-on:

Tributary Protection

• Y cables connect the paired DACs to customer equipment.

• In the Rx direction (from the customer) both DACs receive data, but only the online
Rx DAC sends this data to the TDM bus.

• In the Tx direction, the online Tx DAC sends data to customer equipment, the other
mutes its Tx line interface.

Tributary Always-On

• Separate cables connect each DAC to customer equipment.

• In the Rx direction (from the customer) both DACs receive data, but only the online
Rx DAC sends this data to the TDM bus.

In the transmit direction both DACs send data to customer equipment, and the
customer equipment switches between these two

Protection switching is not hitless. The maximum restoration time for a Tx or Rx trib
switch is 200 ms. Typical restoration times are between 80 ms and 120 ms.

always-on tributaries.

Network/Data Protection

•RWPR

• Data redundancy is supported on Ethernet link-aggregated links.

• Super PDH ring operation supports protection on NxDS1 ring links.

3-12 Aviat Networks

TM

supports fast-switched RSTP on Ethernet ring and mesh networks.

Ring and Mesh Networks

RWPRTM (Resilient Wireless Packet Ring) is a fast-switched RSTP link management
protocol for layer 2 switches. RSTP, itself a fast switched evolution of the original STP,
prevents live network loops and provides path redundancy where two or more paths
exist between network nodes.

• RWPR represents a particularly effective enhanced RS TP protocol. When configured
in Eclipse ring networks, reconvergence times are as low as 50 mS.

Link Aggregation 2+0 Protection

Traffic redundancy is supported on co-channel Ethernet links using link aggregation.
If one link fails, then its traffic is recovered on the remaining link or links is shared.
While the reduced bandwidth may result in some traffic loss for low-priority traffic,
appropriate QoS settings should ensure security for all higher priority traffic. This is
often referred to as 2+0 protection.

Super PDH

Eclipse Installation Manual

Super PDHTM is exclusive to the Eclipse. It supports protected PDH ring configurations
for capacities to 84xDS1, with traffic switching at the node level.

A ring (closed loop) is formed by east/west facing RAC and RFU combinations from an
Eclipse node; each node is connected to two adjacent nodes, the east and west nodes.

Within the ring there are two traffic rings, one nominated as clockwise, the other
anti-clockwise. Under normal no-fault conditions, all traffic is passed on the clockwise
primary ring.

When a fault occurs, the secondary, anti-clockwise ring, provides the protection
capacity needed. Traffic is looped onto the sec ondary ring at one side of the break point,
and off at the other side, to bypass the break. This process is called wrapping.

One or more radio paths can be replaced by a fiber span using the DAC 155oM.

Platform Protection

Platform management functions provided by the NCC are protected using the NPC
option to protect essential Backplane Bus and power supply functions.

Bus Protection

• Protects all circuit/tributary traffic. Alarm I/O is not protected.

• Switching is not hitless for an NCC bus clock failure; restoration is within 200 ms,
during which time all traffic on the NTU is affected.

• When the bus clock has switched to NPC control, it will not automatically revert to
NCC control on restoration of the NCC. Return to NCC control requires either
withdrawal/failure of the NPC, or use of diagnostic commands.

260-668066-003 Rev 001 August 2010 3-13

Chapter 3. System Overview

Power Supply Protection

• Protection is hitless for an NCC power supply failure. If the NCC converter or one of
its supply rails fails, the NPC will take over without interruption. And vice versa.

• With an NPC installed, the NCC can be withdrawn and replaced without further
impacting traffic.

• For 24 Vdc operation two PCCs are required for platform protection, one each for the
NCC and NPC.

Eclipse Licensing

Eclipse is subject to capacity and feature licensing.
Feature Licensing applies on selected features. Currently six features available.

• EZF-01: Layer 1 Link Aggregation (DAC GE). Traffic is between the links on a
byte-by-byte basis, based on the capacity of the links. Unlike L2, it is fully effective
for just one active session, such as between routers, or where there are only a few
concurrent sessions.

• EZF-02: Adaptive Modulation. Eclipse adaptive coding and modulation (ACM)
dynamically switches between QPSK, 16 QAM, 64 QAM, or 256 QAM. Code settings
additionally provide two sets of rates for each modulation; one for
maximum-throughput, the other for maximum-gain, to provide eight modulation
states in total.

• EZF-03: Secure Management (NMS). Applies to Eclipse NMS access over the
network, and to local access via the Portal craft tool. It also enables secure
management access to Eclipse over an unsecured network, and protects Eclipse
configurations from accidental or intentional modification by unauthorized
personnel.

• EZF-04: Payload Encryption. Encrypts all traffic and management data over the
wireless link to prevent eavesdropping.

• EZF-05: Ethernet over TDM (DS3, DS1). Enables mapping of Ethernet data to
DS3, or DS1 PDH interfaces using the DAC 3xDS3M or DAC 16xV2. Supports
transport of Ethernet data over existing DS3 or NxDS1 radio or leased-line circuits.

• EZF-06: RADIUS Client. Enables connection validation to a radius server for
centralized account management.

Configuration and Management

Eclipse is a software-driven product; there are no manual controls. Configuration and
management is achieved via Portal and ProVision.

• Portal is a PC based configuration and diagnostics tool for Eclipse.

• ProVision is the Eclipse network element manager. ProVision also supports other
Aviat products, including legacy products.

Portal is supported in the Eclipse system software, such that once installed on a PC, it
automatically downloads support from the radio as needed to ensure Portal always
matches the version of system software supplied, or subsequently downloaded in any
radio upgrade.

Portal has the look and feel of a Windows environment with screen-based views and
prompts for all configuration and diagnostic attributes.

A Portal PC connects to an INU/INUe/IDU using Ethernet or V.24 options.
For more information, refer to the Eclipse Configuration Guide.
ProVision is the network element manager for all Aviat radios (current and legacy).

ProVision also supports partner products, including multiplexors, switches, routers,
and power systems.

ProVision is installed on a Windows or Solaris server, typically at a network operating
center, and communicates with network elements using standard LAN/WAN IP
addressing and routing; each radio has its own unique IP address.

For more information, refer to the Aviat ProVision User Guide.

Chapter 3. System Overview

Eclipse Power Supply

Eclipse is designed to operate from a -48 Vdc power supply (+ve earth) but will operate
to specification over a voltage range of -40.5 to -60 Vdc.

A plug-in PCC option provides a voltage conversion function for locations where the
power supply is +24 Vdc. It converts + 24 (19 to 36) Vdc to -56 Vdc for connection to
the INU -48Vdc input. -56 Vdc represents the typical float voltage for a battery-backed

-48 Vdc supply.
One PCC supports a maximum three IRU 600 RFUs, plus any combination of RACs

and DACs.
The dc power supply must be UL or IEC compliant for SELV (Safety Extra Low Voltage)

Safety Requirements for Equipment Grounding

1. Ground wires must provide a direct, low impedance path to the Master Ground bar
for the building, which should be located adjacent to the point of waveguide entry
to the building.

2. Do not connect other equipment to the same ground ing cable as the IRU 600. Each

item of equipment in a rack must be separately grounded to the rack ground bar.
The rack ground bar is then grounded directly to the building Master Ground.

3. The IRU 600 and INU must be located in the same immediate area (same or

adjacent racks/cabinets) as with any other equipment that is connected to the same
DC supply circuit point of grounding. DO NOT ground the INU and IRU 600
elsewhere.

4. All intra-building signal cabling must be shielded and both ends of each shield

must be grounded.

5. There shall be no switching or disconnecting devices in the grounded circuit

conductor between the DC source and the point of connection of the grounding
electrode conductor.

Waveguide Grounding

Grounding the waveguide is an essential part of the overall lightning protection sc heme
at the site. The number of waveguide grounds required is dependant on the antenna
height at its centerline. At a height of 45m, the minimum number of waveguide grounds
required is 3:

• One located at the top of the vertical waveguide run, about 1 meter below the bend

before the waveguide goes horizontal toward the antenna,

• One located at the bottom of the vertical cable run, about a meter above the bend

before the waveguide goes horizontal toward the equipment room entry point,

• One located at the equipment room entry way point.

The top and bottom ground is typical ly connected to a tower ground bar, or to the tower
steel using a ground clamp. The entryway ground should be attached to the ground bus
bar, generally located directly below the waveguide entryway point.

If the height of the antenna centerline is greater than 45m, then additional grounds are
required every 25m, or part of, above the 45m level. The topmost one should be located
about 1 meter below the bend before the waveguide goes horizontal toward the
antenna.

NEBS Compliance

For NEBS compliance:

• The equipment is to be grounded to a Common Bonding Network.

• All bare conductors must be coated with an appropriate antioxidant compound

before crimp connectors are fitted.

• All unplated connectors, braided strap, and bus bars must be brought to a bright

finish and then coated with an antioxidant before they are connected. This does not
apply to tinned, solder-plated, or silver-plated connectors and other plated
connection surfaces – but all must be clean and free of contaminants.

• All raceway fittings must be tightened to provide a permanent low-impedance path.

Power Supply

Standard power RFUs are powered over the IF cable from its INU/INUe.
High power RFUs are additionally powered using a separate DC input on the RFU

front panel.

• The high power RFU provides a wide-mouth connection for +/- 21 to 60 Vdc. Both
+ve and -ve pins are isolated from chassis ground.

• The power connector (D-Sub M/F 2W2) and cable is identical to that used for the
INU. See Power Cables.

• Run the supplied power cable through to the power pick up point, which should
be protected by a circuit breaker or fuse in the rack. The circuit breaker or fuse
should have maximum capacity of 8 A.

• For a -48 Vdc supply, connect the blue wire to -48 Vdc (live), and the black wire
to ground/+ve.

5-4 Aviat Networks

Eclipse Installation Manual

• For a +24 Vdc supply, connect the blue wire to +24 Vdc (live), and the black wire
to ground/-ve.

• For NEBS compliance the battery return connection is to be treated as an isolated DC
return (DC-I), as defined in GR-1089-CORE.

• An integral DC/DC converter provides polarity protection, under/over voltage
shutdown, over-current limit, and thermal shutdown.

• NEBS compliant EMI filtering is included.

• There are no serviceable fuses.

The INU/INUe is a rack-mounted unit that pairs with one or more IRU 600s to mak e
an Eclipse node.

An INU/INUe comprises a chassis (IDC/IDCe) and plug-ins.
The IDC/IDCe has dedicated slots for the NCC and FAN plug-ins, and either four slots

(IDC) or ten slots (IDCe) available for optional RAC, DAC, AUX and NPC plug-ins. For
slot allocations and assignments, refer to .

INU Power Supply

INUs require a -48 Vdc power supply (+ve earth), but will operate to specification over
a voltage range of -40.5 to -60 Vdc.

The return (+ve) pin on the NCC and NPC power supply connectors is clamped to
chassis ground via polarity-protecting power FETs.

• NCC and NPC power inputs are reverse polarity protected (the input fuse will not
blow if polarity is reversed).

For NEBS compliance the battery return connection is to be treated as a common DC
return (DC-C), as defined in GR-1089-CORE.

Where operation from a +24 Vdc PSU is required, the plug-in PCC option provides
voltage conversion from + 24 (19 to 36) Vdc to -56 Vdc for connection to the NCC

-48Vdc input. -56 Vdc represents a typical float voltage for a battery-backed -48 Vdc

supply.
The dc power supply must be UL or IEC compliant for SELV (Safety Extra Low Voltage)

output (60 Vdc maximum limited).

6-2 Aviat Networks

Power Consumption and INU Load Maximums

Total power consumed is dependent on the number and type of plug-in cards, and the
number and type of IRU 600s.

• The number and type of RACs and DACs that can be installed in an INU are
determined by the load capacity and temperature limits of the DC converter in the
NCC, which supplies various DC rails to the plug-in cards.

• IRU 600s and FANs are not powered via the NCC converter. Their DC supply is
taken directly from the INU -48 Vdc power supply input connector.

• However, if a PCC is installed for +24 Vdc operation, the INU cards and associated
IRU 600s are supplied from the PCC, meaning PCC power limits are determined by
the INU cards and by the number of IRU 600s fitted.

Node Power Consumption

Table 2 lists nominal power consumption figures for Eclipse cards. Use these together
with the IRU600 consumption figures in the following t able to determine total nodal
power consumption.

Power consumption figures are for a -48 Vdc supply voltage at normal room ambients.

Node Card Maximums

The following guidelines should be used to determine maximum INU card/power
loadings for various node (INUe) configurations. Maximums are primarily determined
by operating temperature limits imposed on the DC converter modules in the NCC (and
NPC).

These card maximums apply up to the maximum ambient of 45
loadings may be permitted for lower ambients. Note that for cabinet-mounted INUs
the ambient temperature is the temperature within the cabinet.

INUe card loading maximums are:

• Five RAC 60 cards plus any three DACs

• Four RAC 6X cards plus any three DACs.
Note that:

• RACs should always be installed on the FAN side of the INU for best cooling
efficiency.

•A 2RU FAN
superior cooling compared to two 1RU FAN modules.

• Elevated ambient temperatures should be avoided. The 45
maximum must not be exceeded. Over-temperature operation is a primary factor
affecting long term component reliability.

PCC +24 Vdc Operation

The PCC is for use with standard +24 Vdc (-ve grounded) battery-backed power supply
systems. One PCC supports a maximum three IRU 600 RFUs, plus any combination of
RACs and DACs.

• The PCC +ve and -ve input terminals are isolated from chassis (ground). The -ve
input is grounded by the -ve grounded power supply connection.

• The PCC 20A fuse is fitted in the +ve input. It is a PCB mount type and is not field
replaceable.

• Reverse polarity protection is provided. The PCC will automatically recover from a
reverse polarity connection - the fuse will not blow. Over temperature thermal
protection is included.

• The PCC load maximum is 200 Watts. Use the power consumption data in the
preceding section to determine the maximum number of cards and RFUs that can be
supported.

• The PCC conversion efficiency is nominally 10%. To determine the power cons umed
by the PCC, use a figure of 10% of the power consumed by the INU/INUe cards and
IRU 600 RFUs.

A 2RU FAN is standard with an INUe, but an INUe can be fitted with two 1RU FANs.

6-4 Aviat Networks

• When installed in an INUe, the INUe must be fitted with the 2RU FAN module as it
provides almost double the air flow of two 1RU FAN modules.

• The PCC should always be installed next to the FAN card to get best air flow cooling.

• The PCC must be connected to the NCC before applying power to the PCC to avoid a
current-inrush trip (overload) on the PCC.

• The PCC can be plugged into any INU/INUe option slot. It is not connected to the
backplane and is its function is not monitored within Portal.

• Where an NPC is fitted, two PCCs are required for +24 Vdc operation, one for the
NCC, the other for the NPC. This means an INUe must be used for NCC + NPC
operation.

• If the PCC front-panel LED is not lit, it indicates the existence of abnormal
conditions such as output under-voltage, output over-voltage, loss of input power,
output over-current, or open input fuse.

Power Cables

The INU power cable is included in the IDC Installation Kit. It is supplied with a D-sub
M/F 2W2 connector fitted at one end and wire at the other. The cable is nominall y 5 m
(16 ft), and the wires are 4 mm

2

(AWG 12).

Eclipse Installation Manual

The cable is used for -48 Vdc connections to an NCC or NPC, or for +24 Vdc
connections to a PCC.

The blue wire must be connected to live (-48 Vdc or +24 Vdc); the black wire to ground
(+48 Vdc or -24 Vdc).

Figure 6-4. Power Cable and Connector

DC power connector can be shorted inadvertently if applied at an angle.
Always insert with correct alignment.

The PCC is supplied with a power cable to connect to an NCC or NPC.
Similarly, the power line filter unit is supplied with a power cable to connect to an NCC,

NPC, or PCC.

260-668066-003 Rev 001 August 2010 6-5

Chapter 6. Installing the INU and INUe

This cable is fitted with a D-sub M/F 2W2 connector at each end. Note that a standard
power cable is not included for the reason the cable supplied with an NCC (or NPC) is
not used when powered from a PCC, or via a power line filter, so the cable is re-used as
the power input cable for the PCC or filter unit.

Fuses

The NCC and NPC are fitted with a fast-acting 25 A fuse fitted on the PCB behind the
power cable connector.

The PCC is fitted with a fast-acting PCB-mounted 20A fuse.
NCC, NPC and PCC fuses are not field-replaceable.

FAN Air Filter Option

A fan air filter option is available for installation with the FAN module in an INU, and
with the 2RU FAN module in an INUe. Where Eclipse is required to be NEBS (Network
Equipment-Building System) compliant, the fan air filter must be installed.

The fan air filter must be inspected regularly and replaced when dust
laden. In normal telecommunications equipment -room environments
inspection must be at not more than 12 monthly intervals. In other
environments where air quality is not controlled, more frequent
inspection is required.

A heavily dust-laden filter will severely restrict fan air flow and
may lead to over-heating.

Excessive heat is the number one cause of premature equipment
aging and failure.

To maximize long term component reliability, the fan air filter
must not be allowed to become clogged, and ambient
temperature limits must not be exceeded.

Fan Air Filter Installation

The fan air filter kit comprises a filter frame, filter element, and fastening screw. It is
installed in the INU/INUe to the right side of the FAN module, as illustrated in Figure
6-5 for an INUe.

1. Remove the FAN module and slide the air filter into the chassis so that it locates to
the right side of the FAN module backplane connector, and up against the chassis
side.

6-6 Aviat Networks

Eclipse Installation Manual

FAN module removal and replacement does not affect INUe traffic.

2. Fasten in place using the screw supplied. Do not over-tighten - the screw is
designed to bite into the unthreaded hole provided in the plastic frame.

3. Replace the FAN module.

Installation instructions are included with the fan filter kit.

Figure 6-5. Location of Fan Air Filter in INUe

Power Line Filter Option

An external DC power line filter option is available and must be installed with an INU/
INUe for NEBS compliance. It ensures Eclipse meets EMI requirements specified
within Telcordia GR-1089-CORE, Issue 4, June 2006.

It is 1RU tall and 140mm wide (5.5”), and is supplied as a kitset comprising the filter
unit, bracket for left or right side rack mounting, and a short 2W2-to-2W2 cable for
connecting the filter unit to the NCC or NPC -48 Vdc inputs.

• Where an NPC is fitted, two filter units are required, one for the NCC, the other for

the NPC.

• The standard power cable supplied with an INU or NPC is re-used as the power input

cable for the filter unit.

INU/INUe Installation Requirements

Table 6-1. INU Installation Requirements

Function/Requirement Details

Restricted access The INU/INUe and its associated dc power supply must be installed

in a restricted access area such as a secure equipment room, closet,
or cabinet.

For NEBS compliance, this equates to installation of the INU/INUe in
a secure, restricted access central office (CO) or customer premises
(CP) location.

Required Rack Space The INU requires 44.5 mm (1RU) of vertical rack space and

300 mm rack depth. The INUe requires 89mm (2RU) vertical rack
space.

Ventilation The INU/INUe requires unobstructed air passage to each side for

ventilation purposes. There must be a minimum of 50 mm (2”) of
side spacing to any rack panels, cable bundles or similar. No space
above or below is required for ventilation purposes.

Fan Air Filter The fan air filter must be installed where the INU/INUe is requir e d

to be NEBS compliant. The filter must be inspected regularly and
replaced when dust laden. Inspection must be at not more than 12
monthly intervals in controlled air environments, or more
frequently otherwise.

this is achieved by grounding the INU to the ground bar in its
equipment rack or frame. This bar is most often located to one side
of the rack or at rack top or bottom. In turn, the ground bar is
grounded to the station ground.

Intrabuilding connections to/from Eclipse ports must only be
connected via intrabuilding or unexposed wiring or cabling.

Intrabuilding ports MUST NOT be metallically connected to
interfaces that connect to the OSP or its wiring. These interfaces are
designed for use as intrabuilding interfaces only (Type 2 or Type 4
ports as described in GR-1089-CORE, Issue 4) 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.

Shielded and grounded cables must be used for intrabuilding
cabling to/from Eclipse ports. Cables must be grounded at both
ends.

Installing / Changing Plug-ins

ESD grounding strap Always connect yourself to the INU/INUe with an ESD

grounding strap before changing or removing a plug-in.
Failure to do so can cause ESD damage to the plug-ins.
Avoid hand contact with the PCB top and bottom.

Finger-grip fasteners Plug-ins must be withdrawn and inserted using their

finger-grip fasteners/pulls. Never withdraw or insert using
attached cables, as damage to the plug-in connector and
its PCB attachment can occur. If not complied with, the
Aviat Networks warranty may be voided.

Hot-swappable Plug-ins are hot-swappable.

• Removal of an in-service payload plug-in will interrupt its
traffic.

• Removal of the NCC will affect all traffic - unless
protected by an NPC.

• Removal / replacement of the FAN does not affect traffic.

Engaging backplane
connector

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.

Revision time lag When swapping or installing plug-ins, up to 60 seconds can

be required for the INU/INUe to show its revised status via
the front panel LEDs, or via Portal.

EMC integrity Plug-ins and blanking panels are held in place by captive

finger-screws. Ensure the finger-screws are fastened as
failure to do so may compromise EMC integrity and fan
cooling.

RACs

Connecting and
disconnecting the RFU
cable at the RAC

Removing RAC from a
powered INU

Never disconnect or reconnect an RFU cable to a RAC
without first turning the power off to the INU or
withdrawing the RAC from the backplane.

Note: The RFU cable provides the power feed to the IRU 600.

Arcing during connection and disconnection at the RAC
on a live RAC can cause damage to connector contact
surfaces. Power spikes caused by live connection and
disconnection may also cause errors on other traffic
passing through the INU/INUe. The only exception to
live disconnection and connection should be for checks
of protected operation at link commissioning.

When removing a RAC from a powered INU, always the
disengage the RAC from the backplane before
disconnecting its RFU cable. Similarly before inserting an
RAC, always reconnect the RFU cable before engaging the
backplane.

Installing an INU

Procedure

1. Fit the rack mounting ears to the chassis with the grounding stud to left or right side
for the most direct ground wire path to the rack ground bar.

2. Locate the INU/INUe in the equipment rack and secure it using four No.12 Phillips

dome-head screws from the IDC installation kit.

3. Where NEBS compliance is required, install the power line filter unit. Install

immediately below or above the INU. Separate filter units are required for the NCC
and, where fitted, the NPC. Use the supplied 2w2 to 2w2 cable to connect the
output of the filter unit to the input of the NCC or NPC.

4. Ground the INU/INUe from the grounding stud to the rack/frame ground bar

using a length of 4 mm
a suitably sized ground lug at each end (supplied by the installer).

•For NEBS compliance, 16 mm

wire is required together with a star washer under the grounding screw. Torque
the INU grounding post screw to 1.2-1.5 Nm (10-13 in-lbs).

5. If the equipment rack/frame requires grounding, use 16 mm

its ground bar to the station ground.

Do not assume that an existing rack or mounting frame is correctly
grounded. Always check the integrity of the ground connections, which
must include a check through to the master ground for the station, which
should be located at the point of cable entry to the equipment building.

For NEBS compliance:

- All bare conductors must be coated with an appropriate antioxidant

compound before crimp connectors are fitted.

- All unplated connectors, braided strap, and bus bars must be brought

to a bright finish and then coated with an antioxidant before they are
connected. This does not apply to tinned, solder-plated, or silv er- plat ed
connectors and other plated connection surfaces – but all must be clean
and free of contaminants.

- All raceway fittings must be tightened to provide a permanent

low-impedance path.

6. Install the plug-ins in their assigned slot positions, and check that their front panels

are flush-fitted (not protruding) and held secure by their fasteners. Ensure unused
slots are covered by blanking panels. Refer to .

Chapter 6. Installing the INU and INUe

Where a fan air filter is to be installed, install it prior to installing the FAN plug-in.

7. Install the CompactFlash card in the NCC plug-in; withdraw the NCC and insert in
the socket on the right side of the PCB.

8. Fit the IF cable between the RAC(s) and IRU 600 RFU(s). IF cables are supplied
with the IRU 600.

Fit the DAC tributary cables.

For a DAC 16x, ensure correct orientation of the Mini RJ-21 connector
before pushing it home. This can be checked by the scalloped key to one
side of the connector . Additional ly, a trib cable supplied by Aviat Networks
will have the cable exiting to the right side when viewed from the front.

Do NOT over-tighten the Mini RJ-21 retaining screws.

The following steps describe the procedure for preparing the power cable, and
preparing for power-on. Do not connect the power until all steps have been
completed.

9. Run the supplied power cable through to the power pick up point, which will
normally be at a circuit breaker panel in the rack. A circuit breaker (or fuse) should
have a capacity of 12 A for the INU and 25 A for the INUe.

10. For a -48 Vdc supply, connect the blue wire to -48 Vdc (live), and the black wire to
ground/+ve. (Power input on the NCC and NPC is polarity protected).

11. For a +24 Vdc supply, connect the blue w ire to+24 Vdc (live), and the black wire to
ground/-ve. (Power input on the PCC is polarity protected).

12. Measure the volt age on the dc power connector.

• For -48 Vdc operation the voltage should be -48 Vdc, +/-2 Vdc for a non battery
floated supply, and nominally -56 Vdc for a battery floated supply. (Limits are

-40.5 to - 60 Vdc).

• For +24 Vdc operation the voltage should be 24 +/- 2 Vdc for a non battery floated
supply, and nominally 30 Vdc for a battery floated supply. (Operating limits are
20 to 36 Vdc).

This product meets the global product safety requirements for SELV
(safety extra-low voltage) rated equipment and the input voltage must
be guaranteed to remain within the SELV limits (60 V maximum) in the
event of a single internal fault.

Always check the integrity of the dc power supply to an INU/INUe right
to its source. Never assume that the supply provided to the pick-up point
in a rack is correct.

Eclipse Installation Manual

Eclipse dc power, IF, tributary, auxiliary and NMS cables are not to be
routed with any AC mains power lines. They are also to be kept away
from any AC power lines which cross them.

13. Carry out a complete check of the installation. If all is correct, and the IRU 600 and
its waveguide, pressurization and antenna installation has likewise been completed
and checked, Eclipse is now ready for power-on. If a PCC is installed, ensure
the PCC to NCC/NPC cable is fitted before power-on.

Once powered up the RFU(s) will be transmitting with the pre-configured or
ex-factory frequency and power settings unless the start-up transmit mute
option has been invoked. (All RFUs shipped ex-factory have the
transmit-mute set as the default unless otherwise specified).

If frequency and power settings are not correct, interference can be caused
to other links in the same geographical area.

14. Power on for -48 Vdc by connecting the power cable to the NCC, and to the NPC
where fitted.

• For +24 Vdc operation, connect to the PCC input.

• Where a power line filter is installed (for -48 Vdc), connect to the filter input.

The 2W2 DC power connector can be shorted inadvertently if
applied at an angle. Always insert with correct alignment.

Next step: The Eclipse node is ready for configuration and antenna alignment.
