connector tip with a dry lint-free cloth. Check if there are scratches or
debris on the connector surface by using a microscope (ie.100x or 200x).
- If no scratch or debris is found, the connector is ready for connection.
If scratches or debris are found, repeat the fiber patch cord connector
cleaning guidelines.
Fiber Bulkhead connectors
- Compressed air may be used to clean fiber bulkhead connectors. Use
compressed air according to the following specifications:
- Non-residue, inert gas for precision dust removal
- Ultra-filtered to < 0.2 microns
- Recommended for optical systems
- Using compressed air as listed above, remove the bulkhead dust cover
and hold the can of compressed air about 6 inches away from the
connector. After spraying a few short bursts into the bulkhead, the
connector is clean and ready for connection.
- If compressed air is not available, the transmitter fiber bulkhead
connector may be cleaned by a 2.5 mm alcohol sponge, or the
connector plate may be removed to clean the internal fiber patch cords.
-To remove the transmitter optical connector plate, remove the screw on
the far left of the optical plate and remove the screw on the far right of
the optical plate. Do not remove the screws on the optical bulkhead
connector.

16 PORT AND CABLE ASSIGNMENTS
MX-A5400 series provides the following management port:
RS232 port: suitable for examining the MX-A5400 parameters and some system
configuration by a PC RS232 port.
SNMP: Simple network management protocol.
Before connecting the MX-A5400 series to a port, please read the following
instructions and port connectivity requirements.
a. Management Port (RJ-45)
i. Port Description
The MX-A5400 series management port connector type is RJ-45.
Figure 4.1.1 RJ–45 Connector Plug and Socket
The Management port (RJ-45) can be connected to any device that uses
a standard network interface (e.g., a workstation, server, bridge or
router). RJ-45 MDI can be connected with similar network equipment
(such as other MX-A5400 or network Hub). Use unshielded twisted-pair
(UTP) or shielded twisted-pair (STP) cable for RJ-45 connections:
100-ohm Category 3, 4 or 5 cable for 10 Mbps connections or 100- ohm
Category 5 cable for 100 Mbps connections. Please ensure that the cable
length does not exceed 100 meters.
ii. Pin assignment
When a network management cable (RJ-45 connector in each side)
connects NMS PC and the MX-A5400 series directly, it should use a
straight through cable. See Figure 4.1.2.

iii. Port Connection
The MX-A5400 series can automatically detect the Ethernet cable type
(Straight-through or Crossover), so either type may be used. An Ethernet

Page 8 of 12
twisted pair cable should be connected between the RJ-45 connector
(MDI-X) of the MX-A5400 series and any device with a standard network
interface (such as a work station or server), or to a network
interconnection device (such as a bridge or router).
1) Ensure that the device to be connected has a 10BASE-T or 100BASE-TX
network interface card (NIC).
2) Prepare a twisted pair Ethernet cable with RJ-45 plugs on each end.
Use Cat 3, 4 or 5 cable for standard 10Mbps Ethernet connections, or Cat
5 cable for 100Mbps Fast Ethernet connections.
3) Plug one end of the cable into the PC's NIC and plug the other end into
any RJ-45 port of the MX-A5400 series. All the MX-A5400 RJ-45 ports
support both 10Mbps and 100Mbps Ethernet connections. Ensure that the
plug's locking tab clicks into proper position to make good connection.
Caution: Do not plug a phone jack connector into the RJ-45 port. This
may damage the EDFA. Instead, use only twisted-pair cables with RJ-45
connectors that conform to FCC standards.
Note:
1) Connect other compatible MX-A5400 series or network hub, adopt
direct or across cable to connect MDI port in other devices.
2) Ensure that the twisted pair cable length does not exceed 100 meters.
3) Cat 5 cable is recommended for all network connections to avoid
confusion or inconvenience, when upgrading to Fast Ethernet devices in
the future.
4) Cascade length provision: IEEE 802.3 standard prescribes that
through twisted pair at most 4 hub (such as repeaters) can be cascaded,
and IEEE 802.3u standard has more strict order for high-speed Ethernet.
So, when cascading devices except for this MX-A5400 series, please
follow the above connection requirements.
iv. Connection Management (Out-Band)
Remote management can be performed through the dedicated
Management port (10/100BASE-TX port) on the front of the MX-A5400 or
any 10/100BASE port of the MX-A5400.
Before the Management port is accessed through LAN port, please
configure the IP address and subnet mask by serial port according to
network configuration requirement.

Page 10 of 12
notices of warnings, and can correct the majority of status deflections of the
equipment, such as: system parameter floating, equipment tolerance, laser aging,
RF level changes, and temperature changes. The PUMP laser will continue
operating when alarming. The alarm will disappear if the facility is self-detecting
continually or the relative system parameter recovers into normal range. Some
serious warnings can be eliminated by restarting the power supply of the unit. The
warning will disappear automatically if the relative parameters recover to normal
range.
Most of warnings will be sent out when the correction ability is close to or exceeds
the permitted range. For most situations, the user cannot modify these statuses.
Status modification needs special equipment & available facility, thus the
modification can only be processed in the factory.
a. Warning status
When pump laser is in warning status, the status LED will turn red and the
brief note of the status will be displayed on the screen. The warning will not
make the EDFA stop operation, and it only shows the relative parameter
exceeding to normal scope slightly. If the warning stops, it indicates that the
relative parameter has returned into the permitted scope. The screen & LBD
will return to their normal status and there is no need for user to interfere.
Note that we should emphasize that the problem displayed by the alarm
should not be ignored, there may be a serious system fault.
