21
GE-DS-82 and NS2503-8P/2C Series User Manual
Before connecting to the other switches, workstations or Media Converters do the following:
1. Make sure both sides use the same SFP transceiver, for example: 1000Base-SX to 1000Base-SX, or 1000Bas-LX to
1000Base-LX.
2. make sure that the fiber-optic cable type matches the SFP transceiver model.
To connect to 1000Base-SX SFP transceiver, use the multi-mode fiber cable- with one side must be male duplex LC
connector type.
To connect to 1000Base-LX SFP transceiver, use the single-mode fiber cable-with one side must be male duplex
LC connector type.
Connect the fiber cable
1. Attach the duplex LC connector on the network cable into the SFP transceiver.
2. Connect the other end of the cable to a device – switches with SFP installed, fiber NIC on a workstation or a Media
Converter.
3. Check the LNK/ACT LED of the SFP slot on the front of the Switch. Ensure that the SFP transceiver is operating correctly.
4. Check the Link mode of the SFP port if the link failed.
Remove the transceiver module
1. Make sure there is no network activity. Use the management interface of the switch to disable the port in advance.
2. Remove the Fiber Optic Cable gently.
3. Turn the handle of the MGB module to the horizontal position.
4. Pull out the module gently the handle.

The Managed Switch offers management features that allow users to manage the Managed Switch from anywhere on the
network through a standard browser such as Microsoft Internet Explorer. After you set up your IP address for the switch, you
can access the Managed Switch’s Web interface applications directly in your Web browser by entering the IP address of the
Managed Switch.

You can then use your Web browser to list and manage the Managed Switch configuration parameters from one central location,
just as if you were directly connected to the Managed Switch’s console port. Web Management requires either Microsoft
Internet Explorer 6.0 or later, Safari or Mozilla Firefox 2.0 or later.

SNMP-Based Network Management
You can use an external SNMP-based application to configure and manage the Managed Switch, such as SNMPc Network
Manager, HP Openview Network Node Management (NNM) or What’sup Gold. This management method requires the SNMP
agent on the switch and the SNMP Network Management Station to use the same community string. This management
method, in fact, uses two community strings: the get community string and the set community string. If the SNMP Net-work
management Station only knows the set community string, it can read and write to the MIBs. However, if it only knows the get
community string, it can only read MIBs. The default gets and sets community strings for the Managed Switch are public.

Administration Console
The administration console is an internal, character-oriented, and command line user interface for performing system
administration such as displaying statistics or changing option settings. Using this method, you can view the administration
console from a terminal, personal computer, Apple Macintosh, or workstation connected to the switch’s console (serial) port.
There are two ways to use this management method: via direct access or modem port access. The following sections describe
these methods. For more information about using the console, refer to Chapter 5 Console Management.

Direct Access
Direct access to the administration console is achieved by directly connecting a terminal or a PC equipped with a
terminal-emulation program (such as HyperTerminal) to the Managed Switch console (serial) port.
When using this management method, a straight DB9 RS-232 cable is required to connect the switch to the PC. After
making this connection, configure the terminal-emulation program to use the following parameters:
The default parameters are:
57600 bps
8 data bits
No parity
1 stop bit
