OS414 is a Linux based 20 port (4 1x4 duplex) optical switch used in patch panel
automation applications. It provides a serial ( S232) and an Ethernet (10/100)
port connectivity for management. Serial port is normally used in special situations
such as to debug network connectivity if OS414 is not reachable through Ethernet.
You might require a Laptop or a PC to configure OS414 with an IP address before
connecting to your network so that you would be able to access OS414 from
remote. You could either use Serial or Ethernet port to configure IP. If you use
serial port using supplied null modem cable then you would need to configure
serial for 38400 baud

would need to configure the PC or Laptop’s IP to match OS414’s default network.
The default network configuration is as follows

There is one non-root default user available on OS414 which can be used once the
switch is setup (for doing switching of port).

The above command configures IP address of OS414 as 192.168.1.10 with mask
255.255.255.0 and gateway & DNS as 192.168.1. Once the IP is configured from a
PC or a Laptop using Ethernet or serial port, you can then connect OS414 to your
network and access it using “telnet” or “ssh”.

Other Administrative commands
Most of other administrative functions can be done using standard Linux
commands. For example, to change the password use “ passwd ” command from the
Linux prompt and to add new user use “ useradd ” command. You have to be “root”
user in order to add a new user.

OS414’s front panel has 4 port blocks each with 5 LC duplex connectors numbered
left to right and top to bottom from 1 to 4. Each port block is an individual duplex
1x4 optical switch, consists of 1 input port labeled as “IN” and 4 output ports
labeled as “O1”, “O2”, “O3” and “O4”. Even though we refer ports as input and
output ports they are bi-directional (duplex) so you can use them as either input or
output. This means switch can act as 1x4 or 4x1 switch
.
Eac
h input ports’ Tx and x are
internally connected to
corresponding output ports’ Tx
and x. OS414 uses 8 such 1x4
switches, as one shown on right, to
provide 20 ports connectivity.

The switching
of light from input port to any of the
four
output ports can be
achieved using a command line interface. To simply the operation, all functions are
provided in a single command called “osctl”. Osctl provides 3 major functions
1. Network & Host configuration (allowed only in “root”)
2. Switch Control & Status
3. Port group Management
Osctl will show correct syntax usage if you make mistakes in typing command
options. It will also provide some examples on how to use the command when you
make mistakes. Also you may use “osctl -?” which shows all syntaxes with all
examples.
Network & Host configuration

by using following command.
$ osctl
osctl osctl
osctl -

Note that the “{}” (braces) groups options and “|” is equivalent to “or”. If the
options are in square brackets “[]” then it is optional. Note: wherever you see
in_port# or port# they represent 1 of 4 port block of OS414.

Port group Management
Port group management commands provide convenience of switching bunch of
ports together identified by a name. Group name can be any alpha-numeric name.
Group name can not be just a number or start with a number. For example group
name can not be “10” or 10gp1. The following are the group commands. Whenever
you see reference to port_group it is same as group name.
Osctl provides 5 different syntaxes to manage port group functions.
1. To create a new group
$ osctl
osctl osctl
osctl -
--
-c
cc
c <port_group>
<port_group> <port_group>
<port_group> {<in_port#/s> | <inport_range>}
{<in_port#/s> | <inport_range>}{<in_port#/s> | <inport_range>}
{<in_port#/s> | <inport_range>}
2. To update existing group
$ osctl
osctl osctl
osctl -
--

roubleshooting
If you use telnet and is very slow, it could be due to name server / DNS
issue. Make sure you have name server configured correctly (-n option).
Try “ping <name_server_ip>” to see if name server configured can be
reached from OS414. If you don’t have dns on your network then you can
just remove file “/etc/resolv.conf” and see if it works normal.
All the group information is stored in a hidden XML database file. If for
some reason this file is corrupted, the system will recover from this error
by trying to copy the backup database file. If this happens it will throw a
warning message but it is not guaranteed that all the group information
will be restored correctly. In that case you may need to recreate missing
groups.

OS414 ports can be cascaded to use as a 1x13 switch. This might be useful if you want to share
13 optical devices with one other optical device. Note that cascading increases the insertion loss
but that shouldn’t an issue for most of the applications. To get a 1x13 configuration you will
have to make following connections:
The above setup needs some sequence of osctl commands to work. For ports 1 to 3 just use osctl
command as in normal case. For ports 4-13 you to follow the following sequence,

It is handy to have a shell script instead of issuing above commands manually.
It is recommended that you install OS414 1 U chassis on a 19 inch rack that meet ANSI/EIA 310-
D and ETS 300-119 standards. We also recommend that you have a 2nd person to assist in the
physical installation of the chassis as its heavy.
Make sure you install the chassis with all 4 screws tightened to the rack. If installation is not
proper you might see that the chassis is not flat (leveled) to the ground, in that case it is
recommended that you install OS414 on a rack tray with rear brackets that comes with the tray.
Trays are sold separately by many vendors. One of them is UI from California ->
http://www.rui.cc/ ACK%20T AYS.htm. Also make sure there are no heavy equipments
sitting (unmounted equipments) on top of OS414.
After installing the chassis, connect the power cable to the power socket at the back of the
chassis and connect the Ethernet port of OS414 at the front panel with a cross-over/straight
cable to a PC/Switch/Laptop to configure network. Also connect optical devices using multimode
cables to the input and output ports of OS414. Make sure Tx and x of MM cable are connected to
B and A of LC connector respectively on both OS414 input and output ports. The order of optical
connection is important; if you connect Tx to B then follow same order on output side as well.
Similarly if chose to connect Tx to A then follow same order on ouput. This is because switch
implements straight through connection as opposed to cross-over.
