Page 13 of 35
The OLT-mini comes with a pre-installed mounting plate that has 4 slotted mounting
holes. The OLT-mini is mounted using 4x 1/4" screws to a backboard or wall of a type
appropriate for the material the OLT is being mounted on. The screws must be adequate
for the OLT-mini's 29.2 pounds. In warmer locations, mounting the OLT-mini in shade
will lower the max temperatures and extend the life of the product.
Power Wiring and Grounding
The OLT-mini power is brought in via the conduit openings and wired to the power
termination blocks on the door of the unit. The unit can be wired for either AC or DC
power. If a DC input from an external rectifier is being used, the AC inputs and wiring
can be ignored.
The wiring is defined in the diagram below:

FlexSym©OLT-mini Installation and Turnup Guide
Page 14 of 35
A ground lug is provided on the bottom of the unit. This should be connected to a
proper earth ground.
Optical Module Installation
Optical Modules must be installed into the OLT-mini. To access the optical modules,
remove the access door from the enclosure.
Remove the two screws as shown below to remove the access door:
The modules can now be slid into and out of the enclosure. Port numbering conventions
are shown below.

FlexSym©OLT-mini Installation and Turnup Guide
Page 15 of 35
The optical modules used should be selected from the modules listed in the site
preparation section of this document.
Both PON modules must be of the same PON type, i.e. both GPON or XGS-PON.
GPON and XGS-PON modules cannot be mixed in the OLT-mini.
The fibers should then be routed into the enclosure via one of the two conduit holes
and routed to the appropriate modules. Labeling of fibers is recommended to aid in
future fiber maintenance. Two fiber slack spools are provided for excess fiber storage
within the enclosure as shown below.

FlexSym©OLT-mini Installation and Turnup Guide
Page 16 of 35
The PON fibers must be single mode SC/UPC.
The uplink fibers are typically LC/UPC and must match the module type (MMF or SMF).
Once the modules are all installed and the fibers routed, replace the Optical Module
Access Door to ensure a weather tight seal of the enclosure.

FlexSym©OLT-mini Installation and Turnup Guide
Page 17 of 35
Powering up the OLT-mini
Once the power and fiber routing is completed, apply power to the OLT. The OLT-mini
will begin displaying LED indications to provide information on the health of the unit.
The device is labeled to indicate the position of each link and its associated LEDs.

OLT Turnup
•OLT-mini Initial Configuration
•Connecting to the OLT-mini
•Connect via μUSB
•Connect via SSHv2
•Turning up the OLT-mini
OLT-mini Initial Configuration
As shipped, the OLT-mini is configured to facilitate quick and easy out of box setup and
testing. This setup is designed to minimize the effort required to establish initial
connectivity. Once connectivity to the OLT-mini is established, it can be configured to
conform to the current network deployment.
Initial Configuration
Setting
Value
Comments
IP Address
192.168.0.10
Change OLT IP once it is manageable to a valid address
within the install environment.
Default VLAN
100 (untagged)
The default configuration makes the uplink untagged to
make it as easy to turn up as possible. The default
management VLAN is 100 but can be changed to any
value. When fully deployed a tagged VLAN is
recommended to ensure seperation of management
and user traffic and to comply with best security
practices.
Uplink
Configuration
All Uplinks in NET1 LAG
Use EMS or turn up to change to the site configuration.
Uplink Speed
Autodetect 10G/1G based on
module.
First module installed will default the uplink LAG speed
and all modules that match will be enabled to pass
traffic.

FlexSym©OLT-mini Installation and Turnup Guide

Connecting to the OLT-mini
Connect via μUSB
The OLT-mini is equipped with an embedded μUSB (microUSB) to serial port interface
which provides direct access to the Command Line Interface (CLI) found on all Tellabs
OLTs. To use this interface, attach a cable from the OLT μUSB port to a USB2 or USB3
port on a PC.
Once the cable is connected, open a serial terminal program (TeraTerm, putty,
HyperTerminal, etc.) Typically, a serial port for the connection is automatically created.
Select the correct port and login to the OLT-mini CLI interface to begin the turnup
process.
Connect via SSHv2
The OLT-mini is shipped with the default IP address 192.168.0.10. When an SFP is
installed into any uplink port, this IP address can be used to access the OLT CLI using an
untagged SSHv2 connection. It is recommended that the default IP address be changed
to avoid a conflict with the next unit turned up. Additionally, the management uplink
should be configured as tagged. Tagging the management VLAN isolates management
traffic from user traffic and reduces exposure to security risks.
Turning up the OLT-mini
Once connectivity has been established, the user will have access to the OLT CLI. The CLI
is used to perform the initial configuration (or turnup) of the OLT-mini. After turnup, the
OLT-mini can be added to and managed by the Panorama PON graphical user interface.
To turnup the OLT-mini, perform the following steps:
•Wait for the system ready message to display and then press ENTER.
