1.4 Management Preparations
After you have decided how to manage your Managed Switch, you are required to connect
cables properly, determine the Managed switch IP address and, in some cases, install MIB
shipped with your Managed Switch.
Connecting the Managed switch
It is very important that the proper cables with the correct pin arrangement are used when
connecting the Managed switch to another switches, hubs, workstations, etc.
1000Base-X / 100Base-FX SFP Port
The small form-factor pluggable (SFP) is a compact optical transceiver used in optical
data communications applications. It interfaces a network device mother board (for a
switch, router or similar device) to a fiber optic or unshielded twisted pair networking
cable. It is a popular industry format supported by several fiber optic component
vendors.
SFP transceivers are available with a variety of different transmitter and receiver
types, allowing users to select the appropriate transceiver for each link to provide the
required optical reach over the available optical fiber type. SFP transceivers are also
available with a "copper" cable interface, allowing a host device designed primarily for
optical fiber communications to also communicate over unshielded twisted pair
networking cable.
SFP slot for 3.3V mini GBIC module supports hot swappable SFP fiber transceiver.
Before connect the other switches, workstation or Media Converter, make sure both
side of the SFP transfer are with the same media type, for example: 1000Base-SX to
1000Base-SX, 1000Bas-LX to 1000Base-LX.And check the fiber-optic cable type
match the SFP transfer model. To connect to 1000Base-SX transceiver, use the
multi-mode fiber cable- with one side must be male duplex LC connector type. To
connect to 1000Base-LX transfer, use the single-mode fiber cable-with one side must
be male duplex LC connector type.
10/100/1000Base-T RJ-45 Auto-MDI/MDIX Port
24 x 10/100/1000Base-T
RJ-45 Auto-MDI/MDIX ports are located at the front of the
Managed Switch. These RJ-45 ports allow user to connect their traditional copper-
based Ethernet/Fast Ethernet devices to the network. All these ports support auto-
negotiation and MDI/MDIX auto-crossover, i.e. either crossover or straight through
CAT-5 UTP or STP cable may be used.
RS-232 DB-9 Port
The RS-232 DB-9 port is located at the rear of the Managed Switch. This DB-9 port is
used for local, out-of-band management. Since this DB-9 port of the Managed switch
is DTE, a null modem is also required to connect the Managed Switch and the PC.
