Adding a 7302 FD Subrack in Existing Racks

•For thermal and cabling reasons, any Alcatel-Lucent subracks(with a maximum of 2 active subracks and 1 passive/splittersubrack) must be positioned in the FD cabinet.

• ISAM LT subracks must be mounted at the bottom of the rack onrack vertical pitch number 60 (subrack pitch number 1). This way,

a free air inlet is created of about 75 mm below the bottom ISAMsubrack.

• The distance between 2 indication lines (identical to the distancebetween 2 mounting holes) is 25 mm. This results in a bottom FDLT mounting position of 60 x 25 = 1500 mm from the top of the

• Above the top ISAM subrack, an free air exhaust space of 75 mmmust be foreseen.

Warnings !

4. Rack Cabling

for Racks with NFXS-A 3FE 26685 AACL

Rack Cabling

Danger 1 —

Before working on the power supplyunit, verify if it is not live. If the power supply islive, which can deliver -48Vdc or -60Vdc, you mustuse an insulated tool kit and consult the manual onworking on live components.

Danger 2 — Avoid risk of electric shock! Always wear protective gloves and footwear for allhandling tasks. Carefully follow the instructions.

External Power Interface on Backpanel

Cables that can be used for the external power cabling

External Power Cabling

All the power cables have to be equipped with an 8 mm lug at one end. The color of thepower cables must be according to local installation practices.

Sample Cabling

Connecting the Power Cables

Alarm Cabling

The rack alarm extension cable(code 3FE 26690 AC, length 1100 mm) canbe used for the alarm extension between

the bottom and middle subrack andbetween the middle and top subrack incase of the NFXS-A 3FE 26685 AACL.

Alarm Cable comes from therack itself to the shelf in thebottom (down port) 1

Rack/Subrack Alarm Extension

The cable must be connected to the RJ45 connectors on the subrack backplane as follows:• The left RJ45 connector is used to connect the alarm cable going to the subrack above

• The right RJ45 connector is used to:• connect the alarm cable from the subrack below (for the uppermost subrack(s))• connect the rack lamps (for the lowermost subrack only)

Door Alarm

Two cables need to be assembled and routed in order to use the door alarm feature:

• The cables are composed of an insulated wire with a minimal cross-section 0.75 mm2 andof sufficient length.

• One end of the cable is equipped with a 6.35X0.81 mm insulated female fast-on connector.

• The other end must be connected to the door contact. The door alarm contact can beconnected to the fast-on connectors DOOR_ALARM_A and DOOR_B on the backplane

External Alarm Extension

The cable is connected on the “CO Alarms up”connector in the lower subrack and on the

“CO Alarms down” connector of the uppersubrack. The external alarm cable is a signalcable with a Sub-B 15-pins connector (cablecode 3FE 27753 AA).

The building blocks of these configurations are one of the following:• duplets: LT board and splitter board

• triplets: LT board, splitter board and POTS board• quadruplets: LT board, splitter board, ISDN board and ISDN board

Supported Mixed LT/Splitter Configurations

Installing ESD Sensitive Boards

ESD Awareness Symbol

Carefully follow these rules when handling ESD sensitive boards.• Transport and store boards in ESD protective bags or boxes• Make sure to wear a grounded wrist strap before handling• DO NOT touch circuit traces or components on the board• Handle boards at front and side edges only.

Ejector Handle

5mm Stiffener

To adjust the difference between the width of the NT board (30mm) and thewidth of the LT board (25mm), a 5mm stiffener is mounted by default beside the

slot for NTB in all delivered 7302 FD subracks.

Note: In case the stiffener isremoved (for example, for makingan NT redundant configuration), itshould be retained for later usewhen the system is converted backto an 18 LT system.

Installing the NT Boards

A 7302 FD subrack has one or two redundant Network Termination (NT) boards.The single (first) NT board is inserted in slot NT A, the redundant board, if any, in slot NT B

Danger: Risk of eye damage or skinburns by LASER emission. Wheninstalling optical boards or handlingoptical fibers, never look insideconnectors of boards or fibers whenthese are not connected.

The board first displays a heartbeat signal,that is, the green “PWR” LED is flashing. Then it displays an enabling operation signal,that is,

• the green “PWR” LED is steady on, • the green “A/S” LED is steady on, • the red “ALM” LED is off.

Installing an NT I/O Board

Each subrack containing one or two redundant NT boards can have only one NT I/Oapplique.

Installing LT Boards in 7302 FD Subrack

The board first displays a heartbeat signal,that is, the green “PWR” LED is flashing. Then it displays an enabling operationsignal, that is,

• the green “PWR” LED is steady on, • the red “ALM” LED is off.

Installing Splitter Boards in 7302 FD SubrackThe splitter boards are placed to the right of the corresponding LT board.

Installing Combined LT/Splitter Boards in 7302 FDSubrack

The board first displays a heartbeatsignal, that is, the green “PWR” LED isflashing. Then it displays an enabling

operation signal, that is,

• the green “PWR” LED is steady on, • the red “ALM” LED is off.

6. Fibre Optic Cable Management

Fiber Optic Cable

Danger: Never look into the end of an optical fiber while optical power is being appliedto the fiber. When cleaning or taking measurements, avoid eye exposure to open-endedfibers and optical connectors. The fibers and connectors may be connected to a laser

transmitter.

Optical Fiber Management Capacity

For Optical LT Boards

Fiber Management Capacity per LT Slot

Note: Up to 18 LT boards are supported in an FD subrack, on the conditionthat there are no rack and cabling restrictions at the customer side. Thefollowing tables show the fiber management capacity per subrack for thedifferent optical fiber types if the Alcatel-Lucent fiber management kit 3FE61087 AA is being used.

Optical Fiber Management Capacity

Fiber Management Capacity per Subrack for NGLT-x Boards

Note: The limitation in capacity is driven by the fiber management kit.

Fiber Management Capacity per Subrack for NELT-x Boards

Optic Modules / Fiber Cables

Managing Fiber Optic Cables for NT Boards andNTIO Boards

The NTs can be populated with either single-mode or multimode SFP and XFPmodules. The NTIO can be populated with either single-mode or multimode SFPmodules. The number of receptacles depends on the board type. Each of theconnectors are LC connectors and have a Tx port and an Rx port.

Routing FiberCables from NTsand NTIO

i ib i bl f d

Managing Fiber Optic Cables for LT Boards

The GPON SFPs require an SC/APC connector. For NELT-A and NELT-B, 90° fiberconnector strain relief boots are required.

Note 1: In the case of bidirectional fiber optic cables as usedwith the NGLT, the transmit and receive signals are carried onthe same fiber and only have one optical connector.

Note 2: The NGLT-x boards must only be used in ISAMsystems with an FD 100Gbps (NANT-D) or an FD 320Gbps(NANT-E) NT board

ib i h d G b d

Fiber connection on the NELT and NGLT board

• The common cable bending area in front of the shelf (or the

board) is 5 cm. In order to be able to shut the rack door thefiber start may not take more than 5 cm. To help theoperator to achieve this a cable bending element can beused.

Fib ti kit

Fiber routing kits

When optical LT boards (NELT and NGLT) are deployed in ISAM shelves, extrafiber guiding elements can be installed to guarantee a proper fiber handling.

Routing Fiber Optic Cables from LT Boards

Fiber optic cables from LT boards must be routed through the MDF cable area andthen up to the top of the subrack. It is also recommended to use protection tubes

in the rack cabling areas to clearly separate the fiber optic cables from the MDFcabling.

Run the fibers left and/or rightthrough cable inlets and ducts:

1. to the left fiber duct forboards in slots 01 to 08

2. to the right fiber duct forboards in slots 09 to 16 andpositions NTIO/17 and

NTB/18

7. MDF Cabling

Dummy Front Panels

Dummy Front PanelsDummy front panels must be mounted onany unused slot of a subrack for thefollowing purposes:

• In case of an active FD-LT subrack:• to ensure EMC compliance• to ensure thermal compliance via a

correct airflow in the subrack• to ensure safety by avoiding direct

contact with backplane connectors

• To allow MDF pre-cabling towards LTboards (FD-LT subrack) or splitter boards(splitter subrack) when needed.

MDF Cabling Guidelines

MDF Cabling GuidelinesBundle and route the cables in an orderly and efficient way.

MDF Cable Bundle

Risk of performance degradation for VDSL when non- VDSL-specific cables are used for LINE cabling.It is recommended to upgrade the LINE SIDE cabling ofthe subrack, when VDSL deployment is foreseen.

Handling Baillocks
