3.4 FITTING SFP CONNECTORS
Care should be taken when inserting/removing the SFP connectors from the SFP port as SFP modules are
Electrostatic (ES) sensitive and Electrostatic Discharge (ESD) precautions should be taken when installing.
Ensure that the SFP is fully engaged and latched into position.
Inserting SFP – Ensure that the SFP lever is in the locked position and insert into appropriate SFP port.
Gently push the SFP until it locks into place. Remove plastic/rubber dust cap and fit appropriate fiber
cable.
Removing SFP – Remove fiber connector. Pull the SFP lever down to unlock SFP from housing. Using
the lever, gently pull the SFP out.

3.5 CLI OVERVIEW
CONNECT TO CLI
The OSD2790SFP has a Mini USB console port connector located on the front of the unit that is used for
Command Line Interface (CLI) from the PC to the OSD2790SFP via the PC’s USB connector.
To operate and control the OSD2790SFP using the CLI, a proprietary driver will be required to be installed
onto the PC being used. The driver can be found and downloaded via the following site: www.silabs.com
and searching for the CP210x driver. Download the relevant driver for your operating system, install and
follow the installation instructions from your PC.

1. Connect the Console Port on OSD2790SFP (Mini USB) to PC with USB cable.
2. Using HyperTerminal, SecureCRT, etc to set up the following parameters.
•Baud Rate: 115200
•Data Bits: 8
•Parity: None
•Stop Bits: 1
•Flow Control: None
3. Check the link by pressing <ENTER>. The line should jump to the next line.
4. Using the Username and password to login the switch
5. If there is no user input for a period of time, the user will be locked out and will require to re-enter
by pressing ENTER.
6. The admin username is operating at the highest priveldge level (level 15) and has full control over
the OSD2790SFP and its configuration. On this level, the admin can reset the OSD2790SFP
configuration to factory default.

Help may be requested at any point in a command by entering a question mark “?”. If there are no
command arguments available, the help list will be empty and the user must backup (backspace) until
entering a “?” shows the available options. There are two types of help provided;
1. Full help is available when the user is ready to enter a command argument (eg. “show”) and
describes each possible argument.
2. Partial help is provided when an abbreviated argument is entered and user wants to know what
arguments match the input (eg “show pr?”)
Note that there are sub-commands for every 1
st
level commands eg. # clear ? will display all sub command
arguments associated with the clear command. The CLI will then display # clear and wait for the sub
command.

SET HOSTNAME AND ADMIN USER PASSWORD
The CLI has several different modes. When entering the CLI through the admin entry, the mode is in exec
mode. This allows the user to modify configuration files, reload defaults, system information etc. When the
unit is in configuration mode, the user can change detailed configurations.
To set the OSD2790SFP host name, the unit needs to be first set to configuration mode then enter the
hostname command, then a chosen hostname. After this is entered, the units requires an ‘exit’ from
configuration mode.
The host name has now changed to “OSD2790SFP-Sec1” and can be seen on the prompt.
A new password for the ‘admin’ user is recommended to be set.
In the example above the password was changed to “OSD”. Other users can be added using the above
method.

SET VLAN 1 IP ADDRESS
To display current IP address and subnet mask details;
# show ip interface brief
To configure a new IP address the unit needs to be first set to configuration mode then enter the interface
VLAN number, then a chosen IP address. An ‘exit’ from configuration mode is also required when
changes are made. Note that the chosen input arguments (IP address/Subnet mask) are not in bold shown in
the example below.
Switch# configure terminal
Switch(config)# interface vlan 1
Switch(config-if-vlan)# ip address 192.168.0.99 255.255.0.0
Switch(config-if-vlan)# end
Note: IP addresses can only be assigned to VLAN interfaces.
After configuration the IP address is completed, the newly allocated IP address can be checked again by
typing in;
# show ip interface brief
If the DHCP negotiation failed, the fallback IP is assigned (192.168.0.99)
SAVE CONFIGURATION TO FLASH
It is necessary to save any changes to FLASH storage in the ‘startup-config’ otherwise the changes will not
take effect when the unit is powered off. To save the changes the configuration needs to be copied to the
startup configuration.
# copy running-config startup-config
