6. Equipment install and maintain
Ø Taken from the packaging machine and accessories, when opening the packing direction, ensure the heads, so as to avoid missing accessories package
Ø Check equipment and accessories in accordance with the packing list, please pay attention to check, and check whether is consistent with the packing list.
Ø Network configuration safey figure, in order to install and maintain.
Ø Please note that don't block device up, down, left, right and ventilation cooling hole
Ø Please note that don't have other impurities inside the chassis. When the equipment into the dust with a soft cloth to clear it.
Ø Please test power line voltage whether is -48V±10% with multimeter before starting up. Protected area is good and room to pick up.
Ø If the device to provide telephone service, please pay attention to distinguish between local site and remote site. Local site equipment connect with switch, remote site equipment connect with user telephone.
Ø Push device fully into the cabinet, make the earmuffs positioning hole and rack installation bracket positioning hole, tighten the rack screws, reliable fixed equipment and cabinets.
Ø Power lines connect
Equipment standard power supply AC220/DC-48V, please confirm the voltage and power consumption whether in the range before access to the power supply
a. -48V power: -48V±10%
b. AC220V power: AC220V±20%, 50Hz
Ø Please check before give equipment introduced power equipment of the power switch is in OFF, if not put OFF, please put it OFF;
Ø Check -48v, the power cord, GND PGND line connection is correct, Note: the work of equipment are separated and protected area, protected area is connected to a chassis. If you need to work can be connected to a protected area in the back the power connection.
Ø Grounding technical advice: Equipment chassis connect PGND, If the local site machine room provide GND and PGND, equipment GND and PGND should insert corresponding ground copper bar. If local site only provide one ground copper bar, allow GND and PGND unite ground connection, ground connection resistance shouldn’t be more than 4Ω
Ø 
Equipment of master-slave clock when the factory has been set up according to the requirements of the user's business!
Pls confirm GND and PGND is OK, If the abnormal situation after add electric power immediately, check and eliminate!
-48V work power line is red, GND is black, PGND is greenyellow and white.
Pay attention to distinguish when connection, make sure not to the polarity of the power supply!
Number remark:
1. Prompted to install personnel when the installation of the equipment must be well protected area, protect the wiring for the yellow-green color
2. Prompt attention when installation personnel is being installed AC220V power electricity safety
3. Prompted to install personnel in 2m line connected to the equipment must first add electric measurement before 2m (E1) interface potential difference between shell and head of cable BNC shell, there is no potential difference 2 m line connection to the device;
Ø The tail fiber connection: Unscrew the tail fiber on both ends of the dust cap, Insert the tail fiber connector lightly to the light in the interface And then screw down the fixed nut, tail fiber one site connect TX, another site connect RX.
Ø 2M line connection: 2M line one site connect E1 IN, another site connect E1 OUT,
6.2 Equipment Common troubleshooting
Ø optical alarm light: NOP light indicate equipment don’t reception optical signal, LOF light indicate optical path out-of-frame, RAI light indicate another site equipment alarm. According to the alarm indicator light alarm indicator can quickly optical path fault judgement.
Ø Check the fiber contact with the equipment are well, Optical fiber plugs on both ends and devices to reconnect mouth in order to protect the connection is good
Ø Optical fiber to reconnect after warning light still have the alarm, need to run out of power meter measuring optical fiber ends the sending power and receiving power of the plate; If send power normal end plate, and the receiving optical power is unusual, thenis fiber; If the plate shine power is very low, and can be judged to be plate problems
Ø Optical plate sending power after normal use the tail fiber to this end equipment of light mouth, from the ring; If the warning light board since the ring is still warning lights, then the problem is the light board, If the warning light goes out after the ring you need to use the same method to test for the end of the light board. If the light on the end plate from the ring alarm lights are off, you can determine the fiber is problematic
Ø When two devices are connected via a single fiber: First ends of the optical module is different, one end is 1310nm optical module, the other end is 1550nm optical module, also the transmission distance is different for example 20KM, 40KM, 60KM etc. When the two ends communicate with each other to ensure the end of the first identified as 1310nm, and the other end is identified as 1550nm, and secondly to ensure the same distance from both ends of the work identified in order to communicate
Ø First check the interface contacts are good and the network cable is connected to the Ethernet interface
Ø Check the cable: Check the pressure line RJ-45 meets the requirements of Ethernet cable, Check the cable line sequence is correct, Connected with the PC using a crossover cable, connected to the Ethernet switch using the straight-through
Ø Check the configuration on both sides of the PC is correct, whether in the same network segment, Correct preparation of both ends of the IP address, Working Group, Gateway etc.
Ø Check the cable is connected to the telephone service interface PHONE
Ø Check the configuration of the device itself telephone line and the telephone service used to qualify whether the correspondence
Ø Equipment and cables connected to a corresponding interface connector is wired correctly
Ø When determining equipment business wiring accurate, please check the device Bureau remote connection is normal, central office equipment connected switches, remote devices connected telephones
Ø Finally, check the phone can work
Ø Check whether interface impedance matching, to ensure that instead of the impedance of the connected device and the impedance of the device itself
Ø Each E1 has light all the way, Indicator said equipment corresponding E1 signal loss, extinguish during normal working, Indicator should check whether equipment E1 2 m cable and BNC good connecting.
Ø Check whether the device itself can work normally, Inspection method is to use 2 m cables connect one equipment sending and reception(E1 loopback), Disappear LOS red light shows that this equipment E1 interface is normal, equipment shall be so check on both ends.
6.3 Equipment business opening
6.3.1 Telephone business opening
Ø Equipment connect order
In the local site, equipment connected to the switch; At the remote site, equipment connected to the ordinary telephone. local end equipment and remote equipment connected by fiber cable.
Ø According to the connection way to connect the various business cable equipment good equipment charging and observe the indicator light after instructions.
Ø Remote telephone connect remote business interface, Off-hook dial, if it is well, so the telephone business opening.
6.3.2 Ethernet business opening
Ø When open Ethernet business Ethernet cable connect Equipment Ethernet interface and PC
Ø Ethernet connect well, please set the IP address, gateway, subnet mask.
