OSD2524P Quick Start Guide
2.2.3 LOCATION
As with any electrical device, the OSD2524P should be placed where the switch will not be
subjected to extreme temperatures, humidity, or electromagnetic interference. Specifically,
the site selected should meet the following requirements:
•The ambient temperature should be between -20°C to 70°C.
•The relative humidity should be less than 95 percent, non-condensing.
•Surrounding electrical devices should not exceed the electromagnetic field (RFC)
standards.
•Make sure that the switch receives adequate ventilation. Do not block the ventilation
holes on any side of the switch.
Note: Without proper cooling and control (lowering) of ambient temperature, the components
within the OSD2524P can be subject to increased heat shortening the longevity and reliability.
It is thus good engineering practice to ensure the unit is installed in a well ventilated area.
2.2.4 POWER SUPPLY CONNECTIONS
The OSD2524P requires external power to the Redundant DC Terminal Block Power
Connector located at the rear of the unit. Always ensure that the power is off before any
installation.
Redundant DC Terminal Block Power Inputs
There are two pairs of power inputs for use with redundant power sources. Only one power
input is required to be connected to run the switch.
Step 1: Connect the DC power to the appropriate power source, connect the plug-able
terminal block on the OSD2524P switch and then turn power on.
Step 2: Disconnect the power if you want to shut down the switch.

PAGE 17 10119802
OSD2524P Quick Start Guide
2.4 COMMAND LINE INTERFACE
The Command Line Interface (CLI) is a useful tool for checking link status and debugging link
connections. To enable the use of CLI the OSD2524P must be connected to a PC with a
serial port and an appropriate cable as specified in section 2.2.5. Using a terminal emulation
program such as Hyperterminal, a number of command lines specific to the OSD2524P can
be implemented to check link/node status, ring/bus topology and enable/disable float backup.
Note: Screen shots may vary due to terminal emulation programs and minor software
updates. The screen shots are for illustrative purpose only.
1. Connect the Console Port on OSD2524P (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 OSD2524SFP and its configuration. On this level, the admin can
reset the OSD2524SFP configuration to factory default.

PAGE 18 10119802
OSD2524P Quick Start Guide
2.4.1 CLI COMMANDS (TOP LEVEL)
By entering “?” a list of CLI commands available with a brief description will be displayed
Some terminal emulators like SecureCRT support the “Tab” key. At the # prompt pressing the
“Tab” key will also produce a list of available commands within the command level. Partially
typing a command and hitting “Tab” key will autocomplete the command.
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 1st 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.

PAGE 19 10119802
OSD2524P Quick Start Guide
2.4.2 RESET CONFIGURATION TO FACTORY DEFAULT
To reset the configuration to factory defaults;
# reload defaults
When the promt returns, the unit has reverted to factory defaults
2.4.3 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 OSD2524P 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 unit
requires an ‘exit’ from configuration mode.
The host name has now changed to “OSD2524P-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.

PAGE 20 10119802
OSD2524P Quick Start Guide
2.4.4 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)
2.4.5 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
