Safety Precautions

Before using the AN6000-15 Optical Line Terminal Equipment, it is important to follow these safety precautions:

• Laser Safety: To prevent laser radiation from injuring eyes, do not look into the end face of a fiber or fiber connector directly with naked eyes.
• ESD Protection:
  • Carpets or other materials that easily generate static electricity should not be used on the floor of the equipment room.
  • Do not touch any components or wires on cards, or metal conductors in sockets. ESD protection measures should be taken if it is necessary to touch the card during maintenance.
• Grounding Requirements: Make sure the cabinet protection earth ground cable and subrack protection earth ground cable are well grounded before powering on the equipment. Check and ensure that the insulation resistance and ground resistance meet the specification.
• Binding Cables:
  • Different types of cables on the installation site should be laid out independently and bound separately. Please note that optical fibers should be bound with dedicated fiber binding straps.
  • Exercise care if you must bend fibers. If bends are necessary, the fiber bending radius should not be smaller than 10 D (D refers to the fiber diameter) and should not be smaller than 30 mm.
  • Cables are bound with appropriate tightness and even distance between cable ties. The cable ties are arranged in good order, and the extra parts of ties are cut from the root without leaving sharp points.
• Inspection Prior to Installation
  Prior to equipment installation, inspect the equipment room, cabinets, power supplies, cables (especially earth ground cables), and supporting facilities. After confirming that the conditions for installation are satisfactory, start the work following project design documents.

Caution

• While pulling an optical module, hold the fiber puller tightly so that the module will not fall down.
• If no fiber puller is available on site, draw out an optical module by pulling its handle

Cards and Components

Installing Cards

Caution

• Before installing a card, check the pins and card connector on the backplane.
• Follow the rules for installing cards.
• If you feel a resistance when inserting a card, pull it out and make sure that you are inserting a card of the correct type to a correct slot in a correct direction. Do not force in the card.
• The core switch card, power card and CIOA card have color marks on both ends. Apply the cards to the slots with the same color marks to prevent mismatch.
• Insert dummy panels to the slots not holding cards. The procedures for installing dummy panels are the same as those for installing common cards

1. Open the latches, align the upper and lower edges of the card with the slide rails in the slot (with the component side of the card facing left), and push the card in along the slide rails slowly.
2. Push the card to its position, and close and secure the card’s latches, as shown in the figure below.
3. Tighten the captive screws on the card panel to lock the card

Installing a Fan Unit

Caution

• Do not operate forcefully; especially do not exert excessive force when installing a fan unit.
• Do not touch the fan blades when the fan unit is running.

Hold the fan unit and align the slide rails on both sides of the fan unit with the slide rail grooves for the fan unit on the subrack respectively. Push the fan unit slowly into the subrack until you hear a click

Preparations for Cable Connection

Instruction

• Internal cables are connected inside a cabinet. Usually they have been connected before delivery. Installers should check the connection of internal cables on site. The items to check include whether the cable distribution is reasonable, whether the wires and cables are properly and neatly arranged, whether the plugs are connected firmly, whether incorrect or poor insertion exists, and whether any part is missing.
• Installers can choose the top access wiring mode or the floor access wiring mode according to the equipment room and the installation site conditions (This guide uses the top access wiring mode as an example).
• The AN6000-15 uses the PDP850A (3000064).

Note

• Before laying out wires and cables, you need to remove the front panel of the PDP. If space is limited for operations, remove the baffle at the bottom of the PDP as well.
• After you have completed layout of wires and cables, restore the front panel and baffle to their original places.

Preparing Wiring Holes on the Cabinet

Instruction

• For a cabinet equipped with mouseproof hop-pockets on the top, fasten the mouseproof hop-pockets after external wires and cables are led into the cabinet and well arranged.
• For a cabinet equipped with a cover plate on the top or bottom, determine the position, size and number of wiring holes according to the wiring plan. Pierce the cover plate with diagonal pliers at desired positions to make wiring holes. The following introduces how to make wiring holes on the top of the cabinet.
  • Prepare the holes from near to far in sequence.
  • Polish the raw edges of the holes so that they will not cut hands or cables.

Connecting External Power Cables

Warning

• Make sure the external power supply is shut off before connecting the power cables. Do not connect the cabinet power cables when the power supply is connected.
• Make sure the DC power input is cut off during cable connection, and attach labels to the switches to be used.
• Never expose the joining part of a power cable or a power connector unless necessary.
• If the bonding resistance between the equipment ground cable and the earth ground bar is higher than 0.1 ohm, the ground cable should be re-arranged.

Caution

• With the premise that cables must be arranged in compliance with the route, the power cables should be processed on site according to the “shortest” route principle.
• The power cables should be made of a continuous segment of copper core with no intermediate connections.

Instruction
The protection earth ground cable for a PDP has been connected with the PE terminal before delivery of the PDP; you only need to connect the other end of the cable to the earth ground point on the top of a cabinet on site

1. Connect the cabinet earth ground cable to the earth ground bar in the equipment room.
2. Lead the -48 V and 0 V power cables into the cabinet.
3. Remove the front panel of the PDP
4. Connect the cabinet power cables to the PDP and the external power supply respectively. The terminals on the PDP from left to right are -48V_A, 0V_A, 0V_B, PE and -48V_B respectively.

Processing External Power Cables
“Cut-Wrap-Crimp-Insulate”

1. Measure a power cable and cut an appropriate length of it as needed with a wire clipper on site.
2. Wrap the bare end of the cable with an insulating tape to prevent short circuit during cable layout.
3. After leading the cable to the desired position, remove the insulating tape, strip the cable end with stripping pliers, install a copper terminal onto the cable end, and crimp it with hydraulic pliers.
4. Insulate the terminal with an insulating tape or a heatshrinkable tube.

Connecting Subrack DC Power Cables

Caution

• Make sure that the power control switch for the corresponding subrack on the PDP is placed in the OFF position before laying the power cables.
• Completely insert the cord end terminals into the terminal blocks on the PDP. To ensure good connection, the metal part exposed should not exceed one sixth of the overall metal length. The length of the exposed insulation covering or metal part of terminals in the same row or batch should be equal whenever possible.
• Do not press the insulation covering of cord end terminals, which may cause poor electrical connection.
• Make sure the side with a larger area of a cord end terminal contacts the terminal block.
• After connecting power cables, attach a label indicating the cable information to both ends of each cable, 1 cm to 2 cm away from the connector on each end.

Instruction
The figures below illustrate how to connect the subrack power cables to the subrack and the PDP850A (3000064).
