a Precautions

•Specify the type and quantity of network interfaces based on service requirements. It is recommended to

connect the service cables of the same type to network interfaces from the left to right.

•As the Ethernet service interfaces support the adaptive function, the network cable can be either

crossover cable or straight through cable. The straight through cable is recommended.

When installing or maintaining fibers, do not look into the optical port without eye protection. See Figure 1.

NOTE

When routing fibers, take proper measures to avoid any damage to fiber connectors.

After installing the fibers, place protective caps on the idle optical ports and place fiber caps on the idle

fibers. See Figure 2. The type of the fiber connector is LC/PC.

• Specify the type and quantity of optical

interfaces based on service requirements.

• Optical modules can be delivered with the

device or separately. Optical modules that are

delivered separately must be installed on the

device on site.

ETH/OAM

NM (network management)

NOTE

The NMS cable is a serial cable and has different pin arrangement than a common network cable. When the

ATN device is powered on for the first time, use the NMS cable to connect the ETH/OAM interface (Console

interface) to establish the local configuration environment. After the configurations (such as IP address and

static route) are complete, replace the NMS cable with a network cable and use the network cable to connect

the ETH/OAM interface (Console interface) of the ATN device to the network.

To check the connectivity of the network cable, you can also adopt the approach of looping back the data

ports (applicable to the data ports on two sets of equipment that is powered on). That is, connect the two

data ports with the network cable. If the LINK indicator is on, it indicates that the network cable is normal.

NM center

1. An hardware installation engineer powers on the device, sets up optical paths, and informs a software commissioning

engineer in the network management (NM) center that the device is powered on and optical paths are set up.

2. The software commissioning engineer searches for and creates NEs to ensure that the device can be managed remotely.

Then, the software commissioning engineer configures data for the site to ensure that the device is functioning properly

and alarm and performance data can be reported.

3. The software commissioning engineer sets outloops for E1 ports on the NMS, and instructs the hardware installation

engineer to test the bit error rate (BER) using a BER tester.

• If no bit errors occur or loss of signal (LOS) signals are displayed, the E1 cables are normal;

• If bit errors occur or LOS signals are displayed, check whether the 2 Mbit/s cables are incorrectly connected or poor

soldering occurs.

Installation Checklist

No. Item

1 The chassis are positioned in the proper place as prescribed by the engineering design specific to the site.

When the chassis is installed in a 19-inch cabinet, make sure that the chassis does not come into contact

the front door and that the cables are not pressed against the front door when it is closed.

2 Each chassis component does not have any paint drop, damage, or stain. Otherwise, re-paint or clean the

component.

3 Cables are routed according to the engineering design, facilitating future maintenance and expansion.

4 Cables are not damaged or broken, and there are not any joints on the cable.

5 Cables are tested for connectivity.

6 Cables are bundled closely with proper force. The spacing between the cable ties is even. After the cable

ties are fixed, the remaining part is trimmed with no burrs.

7 Signal cables are routed correctly.

8 Cables outside the cabinet are routed as follows:

• Cables are laid neatly without crossing.

• If a cabling ladder is used, the cables should be bound onto the ladder beam neatly. If the cabling frame

is 0.8 m or higher than the cabinet top, a cabling ladder must be available on the cabinet top to support

the cables and to ease stress.

9 The cable turns are smooth and have a big bending radius.

10 Cable labels are marked correctly and firmly attached. They are aligned and face to the same direction.

The labels need to be placed two centimeters away from the connectors.

11 The power cable and grounding cable are routed separately from the signal cables.

12 Protective caps are placed on unused cable connectors for protection.

13 The protective tube for fiber jumpers is led into the cabinet and the tube inside the cabinet is about 10 cm.

If the cut end of the tube has sharp edges, wrap it using insulation tape.

14 The cut end of the protective tube for fiber jumpers is smooth and without sharp edges. If the cut end is

not smooth, wrap it using insulation tape.

15 The fiber jumpers are not tightly bound and are able to moved freely in the cable tie.

16 The connecting points of fiber jumpers are free from dust. The unused fiber connectors and optical

interfaces are protected by protective caps or plugs.

NOTE

To check tail fiber connection, you need to check the deviation of the optical power between an optical

interface on the board and the peer interface on the ODF. If the optical power meter reads a value less than

or equal to 1 dB, it indicates that the tail fiber connection is correct. Otherwise, check the fiber.

If the fiber is connected through a flange, the deviation should be less than 2 dB.

When using an optical power meter during a test, you are recommended to record the launched optical

power of each optical interface and check whether the launched optical power is normal.

Consult the project supervisor or software engineer and determine whether it is necessary to test the

received optical power by using an optical power meter, with an intention to check whether the received

optical power is normal.
