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 other 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
communication 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
connecting 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 matches the SFP transfer
model. To connect to 1000Base-SX transceiver, use the multi-mode fiber cable with male
duplex LC connector type for one side. To connect to 1000Base-LX transfer, use the single-
mode fiber cable with male duplex LC connector type for one side.
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 be connected to the Managed Switch and the PC. By connecting
this DB-9 port, it allows you to configure & check the status of Managed Switch even when
the network is down.
