WARNING:

• Use multiple persons to move or lift a chassis and take measures to protect personal safety.

• Laser beams will cause eye damage. Do not look into bores of optical modules or optical fibers without eye protection.

NOTICE:

• During equipment transport and installation, prevent the equipment from colliding with objects like doors, walls, or shelves.

• 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 device to be installed must be used indoors. To ensure normal operation and long service life of the device, the following requirements must be met:

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

• Dustproof measures must be taken in the installation site. This is because dust will cause electrostatic discharges on the device and affect connections of metal connectors and joints, shortening the service life of the device and even resulting in device failures.

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

• The device that is operating may cause radio interference. If this is the case, relevant measures may be needed to reduce the interference.

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

The device must be installed in an IEC 19-inch cabinet or an ETSI 21-inch cabinet. If customers choose to purchase cabinets by themselves, the cabinets 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. If the cabling space is insufficient, cables will block the cabinet door from closing. Therefore, a cabinet with broader cabling space is recommended, such as a cabinet with a convex door.

3. The device draws air from the left side and exhausts from the right side. Therefore, if the device is 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 to ensure good ventilation.

4. The porosity of each cabinet door must be greater than 50%, meeting heat dissipation requirements of devices.

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

6. The cabinet has a ground terminal to connect to the device.

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

NOTE:

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

• For cabinets with left-to-right air channels, such as open racks, installing cabinets side by side may cause cascaded heating. Therefore, you are advised to install cabinets with left-to-right air channels vertically at different levels rather than side by side. If side-by-side installation cannot be avoided, it is recommended that the distance between cabinets be at least 500 mm (19.67 in.).

• If the device requires optical modules or attenuators with a puller, ensure that sufficient space is available for routing optical fibers. For a convex door or open rack, it is recommended that the distance between the cabinet door and the front panel of the board be greater than or equal to 120 mm (4.72 in.).

CAUTION:

• When installing a device in a cabinet, 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.

NOTE:

• Certain steps support two installation modes. Select a proper PGND cable installation mode according to cabling requirements. The PGND cable can be connected to either the front or side face of the device. Connecting the cable to the side face is preferred.

• Figures in the document are for reference only, and the actual device appearance may vary depending on the exact device model.

1. Install floating nuts onto the cabinet.

2. Connect the PGND cable to the front or side face of the device. Connecting the cable to the side face is preferred.

3. Install the device into the cabinet using M6 screws.

1. Install floating nuts onto the cabinet.

2. Install the conversion mounting ears on both sides of the chassis using M6 screws.

3. Connect the PGND cable to the front or side face of the device. Connecting the cable to the side face is preferred.

4. Install the device into the cabinet using M6 screws.

Common cables include:

• PGND cable

• DC power cable

• Optical fiber

• AC power cable

• Shielded Ethernet cable

• 120-ohm 16 x E1 cable

• 75-ohm 16 x E1 cable

NOTE:

• To ensure that power cables are connected in order, you are advised to plan power cable routing.

• It is recommended that power cables and ground cables be routed on the left side of the cabinet. It is recommended that cables, such as optical fibers and Ethernet cables, be on the right side of the cabinet.

• 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.

First, check the fuse capacity of the external power supply and the maximum cable size.

After checking, select a cabling mode according to the actual DC power supply port type of the device and connect the cables.

First, check the fuse capacity of the external power supply.

After checking, select a cabling mode according to the actual AC power supply port type of the device and connect the cables.

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.

NOTE (Best Practices):

• 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.

This step is required only for the ATN 910C-K chassis. It is recommended that E1 cables and Ethernet cables be routed in interleaving mode.

NOTE:

• It is recommended that the ATN 910C-K chassis use Ethernet cables crimped onsite.

• Bundle the network cables in a rectangle shape. Ensure that the cable ties are evenly spaced and face the same direction.

• Before bundling network cables, use a network cable tester to test cable connectivity.

• In a 300 mm deep cabinet with a flat door, common shielded network cables are not recommended when electrical modules are used. Instead, use Huawei-customized conversion short pigtail shielded network cables.

Check Before Power-on:

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

• Check whether the fuse capacity of the external power supply meets requirements.

• Check whether the external power supply voltage is normal.

CAUTION: If the power supply voltage does not meet requirements, do not power on the device.

Power-on Check:

WARNING:

• Before performing a power-on check, turn off all the switches on the device and external power supply system.

• If indicators are in specified abnormal states after you power on the device, handle the abnormalities onsite.

The following table describes the states of indicators when the device is operating properly.
