1. IntroductionThank you for selecting MetroEdge-Express, the SDH based fiber optic multi-service
access platform.
The MetroEdge-Express is built on SDH/MSPP technology. It is aimed at providingboth TDM based traditional telecom services and ever growing Ethernet based data services.
There are two types of equipment in the MetroEdge-Express family, the CPE end equipment
(hereafter referred to as LM, LMC, LMV, LM63 and LMFIT), and the aggregation
equipment at the central office (hereafter LMX). There are three types of CPE equipment in
MetroEdge-Express, show as follow.
Table 1-1 Difference between CPE models
Model Feature
LMFIT 4 interface slots, multi-interface card selections include:
DS0 64k Cross-connection DXC card, fiber optic interface card Dual

The console port is a RS232 serial port for command line access to the internal
microcontroller system. [Software version 1.2.1 or above adopt Telnet instead of F interface
and delete RS232 interface]. The console port can be connected to a VT100 dummy
terminal, or a PC running terminal emulation program such as the windows HyperTerminal.
The console port protocol is 9600 baud, 8 data bits, 1 stop bit, no parity, no flow control.
The main function of the console is to modify hardware parameters such as the node address,
etc. It can also be used to check operational status, or issue simple commands. The
command input is not case sensitive. Console access is password protected. Default
username is admin, and default password is hhpostern or admin. The user can change
the user name and password. If no key stroke is performed in 3 minutes, the system will
automatically log off.
Orderwire:
The RJ11 port (label: OW) at the right is the phone jack for orderwire telephone. This
telephone is also used as a hand held input device for LCD menu selection.

Power Inputs:
The H9MO-LM FIT can be powered either with -48VDC or ~220VAC supply. The flip
switch selects the power input. When flipped up, -48VDC is selected, and ~220VAC is
selected with switch flipped down. The middle position switches the power off..
Use standard AC power cord supplied with the unit to connect to the ~220VAC power
supply.
Use power outlet with secure earth connection to avoid danger of electricshock.
-48VDC power supply is connected to the LM through the PWR-IN socket, a plug is
supplied for the socket. Connect power wires to the plug according to Fig.3.3-2. Insert the
prepared wire end into the hole on the left end of the plug, tighten the screw to securely fix
the wire to the plug. After fixing all the wires, push the plug into the socket.

Shelf Alarm Output:
The H9MO-LM FIT can output system alarms for maintenance purposes. The shelf
alarm port is socket. There are 2 alarm output pins, the Prompt Alarm (P) and the Deferred
Alarm (D), as shown in Fig. 3.3-3, in the 3.5mm plug for shelf alarm port. The alarm
conditions for each alarm output are set by the user. The output ports float when no alarm is
present, and connect to ground when alarm activates.

Optical Port:
Default fiber optic interface is the dual fiber SC socket type, with nominal wavelength
of 1310nm and link range of under 40km. Tx denotes output port, and Rx the input port.
With single fiber option, only one fiber socket is used for both input and output. Single fiber
module transmits and receives optical signals in different wavelengths. Only transmit
wavelength is specified. Usually, the single fiber version LIU on LMX transmits at 1310nm,
and single fiber LM FIT transmits at 1550nm. Note that when two single fiber LM FITs are
to be linked point-to-point, they must have different transmit wavelength.

3.6 Installation and Operation
Connect power supply with correct voltage to the appropriate power-in sockets.
Connect fiber optic connectors into the FO socket on the rear panel. Pay attention to the
transmit and receive relationship. When plugging in the connectors, make sure the peg on
the connector is aligned with the opening on the socket. Push firmly all the way until click.
Do not drag the fiber when unplugging. Keep fiber bending radius above 50mm. Please
keep aside the socket cap, and always cover the socket with the cap to prevent dust
whenever fiber is removed.
Switch on the power, the system starts to boot-up. The LEDs may twinkle randomly.
The boot-up takes about one second, and the system starts normal operation.
Select correct clock mode. The line clock mode is for slave and internal clock for
master.
Check the alarm LEDs. Check fiber connections or the received optic power if some
of these LEDs shines of the F155-DO or F155-D. Since the E1s are not connected yet, the
E1 alarm LEDs will be on of the F4E1 card and F8E1 card, which can be masked out.
Connect the Ethernet cables to appropriate ports. Check their status LEDs. The link
should work as intended. The maximum channel bandwidth of the Ethernet is 100Mbit/s.

4. Network Management
An access network built with MetroEdge-Express product can be managed with the
network management software package H7GMSW.
The H7GMSW is a GUI based network element management software package. It
supports both SNMP and TABS protocols. At the physical layer, SNMP uses Ethernet,
while TABS uses RS485 to connect to the monitored equipment. H9MO-LMFIT supports
SNMP and TABS.
The software models the monitored network in 3 different perspectives: the
network/area view, the site/element view, and the equipment/card view. In the
network/area view, icons represent equipment sites are connected with lines representing
fiber optic connections, forming networks. Double click on a site icon enters into the
site/element view. Installed equipment in the site is graphically represented. Double click
on the equipment or cards inside the equipment brings up the equipment/card window.
Alarms will be indicated at any level by flashing the respective icons, and detailed defects
are shown at the equipment/card window. Control on individual equipment or card is also
done at that window. Control at the network level, such as channel allocation, is done at
the network/area window.
How to get the IP address of the device?
You can get the IP address of H9MO-LMFIT by dip switch. Push down the first dip
switch and you can see the IP address is displayed in the LCD.
How to change the IP address of the device?
Login in telnet and you can change the IP address of H9MO-LMFIT.
Login in telnet. Both the user name and password are admin.
