• Move an unpacked chassis upright. Do not drag it with it lying down.

• Do not touch unpainted surfaces of the equipment with wet or contaminated gloves.

• Do not open the ESD bags of cards and modules until they are delivered to the equipment room. When taking a card out of the ESD bag, do not use the connector to support the card’s weight because this operation will distort the connector and make the pins on the backplane connector bend.

Before installing, operating, or maintaining the equipment, wear an ESD wrist strap and insert the other end into the ESD jack on the chassis or cabinet. Remove conductive objects like jewelry and watches to prevent damages to the equipment and cards caused by electrostatic discharge.

The HUAWEI ATN 910C-G must be used indoors. To ensure normal operation and long service life, the following requirements must be met:

• The device needs to be installed in a clean, dry, well-ventilated, and temperature-controllable standard equipment room. The equipment room must be free from leaking or dripping water, heavy dew, and condensing.

• Dustproof measures must be taken in the installation site. Dust can cause electrostatic discharges, affect connections, shorten service life, and result in device failures.

• The installation site must be free from acidic, alkaline, and other types of corrosive gases.

• The device may cause radio interference. If this occurs, relevant measures may be needed to reduce the interference.

• Generally, wireless antennas should not be installed in the equipment room. If they must be installed indoors, ensure the electromagnetic environment meets requirements or take necessary shielding measures.

The device must be installed in an IEC 19-inch or an ETSI 21-inch cabinet. If you purchase your own cabinet, it must meet the following requirements:

1. 19-inch or 21-inch cabinet with a depth of greater than or equal to 300 mm.

2. The cabling space in front of the cabinet complies with the cabling space requirements of boards. It is recommended that the distance between the cabinet door and any device board be greater than or equal to 120 mm. A cabinet with broader cabling space, such as a convex door, is recommended.

3. The device draws air from the left side and exhausts from the right side. If installed in a 19-inch cabinet, there must be a clearance of at least 75 mm at the left and right sides of the cabinet for good ventilation.

4. The porosity of each cabinet door must be greater than 50% to meet heat dissipation requirements.

5. The cabinet must have installation accessories, such as guide rails, floating nuts, and screws.

6. The cabinet must have a ground terminal to connect to the device.

7. The cabinet must have a cable outlet on the top or at the bottom for overhead or underfloor cabling.

• The cabinet may be installed on an ESD floor or a concrete floor.

• For cabinets with left-to-right air channels, installing them side by side may cause cascaded heating. It is advised to install such cabinets vertically at different levels rather than side by side. If side-by-side installation is unavoidable, the distance between cabinets should be at least 500 mm (19.67 in.).

• If the device requires optical modules or attenuators with a puller, ensure sufficient space for routing optical fibers. For a convex door or open rack, the distance between the cabinet door and the front panel of the board should be 120 mm (4.72 in.) or more.

• Ensure that the total heat consumption of all devices in the cabinet does not exceed the heat dissipation capability of the cabinet.

• To prevent air return from affecting heat dissipation, leave at least 2 U space between devices in the cabinet.

• Do not block the heat dissipation holes on panels.

• A device that needs to share the same cabinet with other devices cannot be installed near the air exhaust vents of those devices.

• Consider the impact of a device’s air exhaust vent on adjacent devices to prevent high temperature.

• When fastening floating nuts, ensure that there is at least 75 mm space on the left and right sides of the device for ventilation after device installation.

• If cables are routed on the rear of a device, ensure that the cables do not block the air vents of the device to achieve proper heat dissipation.

• Before routing cables, make temporary labels and attach them to the cables. After the cables are routed, make formal labels and attach them to the cables as required.

• Do not bundle or route outdoor cables (such as outdoor antenna feeders and outdoor power cables) and indoor cables together in the cabinet or cable tray.

For a DC-powered HUAWEI ATN 910C-G, the recommended fuse capacity of the external power supply is ≥6 A. For hierarchical power supplying protection, the current of the circuit breaker at the user side should be no less than 6 A. The maximum cable size is 4 mm².

For an AC-powered HUAWEI ATN 910C-G, the recommended fuse capacity of the external power supply is ≥1.5 A. For hierarchical power supplying protection, the current of the circuit breaker at the user side should be no less than 1.5 A.

WARNING: When performing operations such as installing or maintaining optical fibers, do not move your eyes close to or look into the optical fiber outlet without eye protection.

CAUTION: Before routing internal optical fibers, install fixed optical attenuators at the corresponding optical ports on devices according to the fixed optical attenuator installation table.

General Guidelines:

• The bending radius of a single-mode G.657A2 optical fiber is no less than 10 mm, and that of a multi-mode A1b optical fiber is no less than 30 mm.

• After laying out optical fibers, use binding straps to bind the fibers neatly without squeezing them.

• After the optical fibers are connected, the optical ports and optical connectors that are not used must be covered by dustproof plugs and dustproof caps, respectively.

• Do not use an open-end corrugated pipe to hold excessive optical fibers. It is recommended that an open-end corrugated pipe with a diameter of 32 mm accommodate a maximum of 60 fibers with a diameter of 2 mm.

• It is recommended that the length of a corrugated pipe inside a cabinet be about 100 mm.

Before powering on the device, perform the following checks:

• Check whether fixed optical attenuators have been added in accordance with corresponding configuration rules.
