5.3 Safety Items
n Optical interface
To ensure personal safety, please operate the optical maser according to the following rules:
－Please take good care of the fiber and cleanse it before usage. Also please put the protective cap onto the fiber before it is linked to the fiber connector, just in case of the pollution and physical lesion.
－Maintainer and operator have to be well trained.
－Don’t look squarely at the fiber cross-section before the light source is shut down.
Note: Bend-radius≥30mm。
n Electric interface
The input voltage is this equipment is -48VDC.
n Static damage prevention
The operator has to put on antistatic equipment to touch circuit board.
5.4 Machinery installation
IDM-MSTP155-24 chassis should be installed on a 19” standard rack. To ensure the ventilation , the equipment should be at least 1U away from adjoining items.
Under normal circumstances, please do not block the louver.
During the installation, most faults are caused by the poor connection of PGND and GND, so please take care of the common-ground issue.
5.5.1 Server room wiring
Ø According to the actual situation of the server room, fix the power line, E1 cable, fiber, users’ line and network management line trimly and regularly to the rack.
Ø In case of the interference, power line and data wire should be separate.
Ø Fiber connection
1. Before the test of optical interfaces, to ensure the accuracy, all optical connectors should be cleaned.
2. Insert the fiber connector to the equipment optical interface connector tightly.
3. In a point-to-point network, connect either TX on equipment A to either RX on equipment B and the other RX on equipment A to the other TX on equipment B. In a ring network, connect TXB and RXB on equipment No.1 to RXA and TXA on equipment No.2 respectively. Connect TXB and RXB on equipment 2 to RXA and TXA on equipment No.3 respectively. On the analogy of this, finally connect TXB and RXB on equipment No.n to RXA and TXA on equipment No.1 respectively.
4. Bond the fibers to the rack with cable tie, all connection is done.
Ø E1 cable connection
When do the E1 cable connection, please be careful of the cable matching. Don’t plug/unplug too hard so as not to damage or deform the pins.
Ø All cables should be placed in the chute with binding ties after the connection.
5.6 Power supply installation
Ø The power supply switch should be “OFF” before hook up.
Ø The power configuration of a standard model is dual power supply (DC -48V and AC 220V), when either one fails, the other will back it up.
DC -48V：-48V±10％
AC 220V：220V±20％
Before power-up, please use multi-meter to test the power supply, so as to find out if short circuit exists and the voltage is normal.
Ø The GND and the PGND should be separate. The PGND should be connected to the frame.
Ø Power up after all the check-up.
5.7.1 Chain network connection
When the chain network is established as below, pilot lamps LOSB and LOFB of equipment No.1 are off and LOSA and LOFA are on. Pilot lamps LOSB and LOFB of equipment No.N are off and LOSA and LOFA are off. Pilot lamps LOSA, LOFA, LOSB and LOFB of the others in between are all off.
Diagram5-1 IDM-MSTP155-24 chain network connection
1. Pilot lamps NET1, NET2, NET3 and NET4 of each equipment are one-to-one correspondences, after the connection of Ethernet, pilot lamps LINK, FULL and 100M/ACT will be on.
2. The equipment is in normal operation condition and all services are all standing by.
When the ring network is established as below, all pilot lamps are off.
Diagram5-2 IDM-MSTP155-24 ring network connection
1. Pilot lamps NET1, NET2, NET3 and NET4 of each equipment are one-to-one correspondences, after the connection of Ethernet, pilot lamps LINK, FULL and 100M/ACT will be on.
2. The equipment is in normal operation condition and all services are all standing by.
5.8 NM (network management) software installation and configuration
Please check《Network Management Users’ Manual》for your reference.
6 Common faults
Please check if the device power line access is correct and the voltage and consumption are the right matching with the equipment. The power supply must be stable and reliable and the PGND should be well connected, so as to be free from lightning strike.
1. Check up if there is a loose contact between fiber and equipment.
2. Check if the equipment itself is working well. To do the test, connect RX and TX (on the same equipment) with a fiber, if the alarm indicator doesn’t go on, that’ll mean the equipment has no problem.
3. If the equipment still doesn’t work after the above tests, please check out the fiber circuit.
4. Dual fiber unidirectional optical module: wavelength is 1310nm. The transmitting range is 40km, 60km and 80km. Please make sure the wavelength and transmitting range of the modules at two ends are same.
Check if the interface impedance settings are right, if yes, please use code error tester to test hop by hop, in this way, users can find out if it’s an equipment fault, transmission fault or setting fault.
1. Firstly check if the twisted pair is well connected.
2. Check up the RJ45 PINs order, “cross-over” for connection to PC and “straight-through” for connection to switch.
3. Check if the configuration of PCs at two sides is right.
6.4.2 E1 service fault
1. First check up for the poor contact of 4×E1 plug and the 2mm high-density connector.
2. Check up if the wiring order is right and the pins of 2mm high-density connector is deformed or damaged.
