Serial management interface (DB9 Console port)
The serial management interface allows you to configure and manage the device using a
third-party terminal emulation application on a directly-connected PC. A straight-through EIA or TIA
DB9 serial cable (M or F) ships with the device. The serial management interface (the DB9 Console
port) is located in the left corner of the front panel.
Out-of-band RJ45 management interface
The out-of-band RJ45 management interface enables you to configure and manage the device
using a third-party terminal emulation application on a directly-connected PC.

PowerConnect B-FCX 10/100/1000 BASE-T ports
All PowerConnect B-FCX devices except for the fiber models contain 24 or 48 RJ45 ports that
operate at 10 Mbps or 100 Mbps, half or full duplex, or at 1000 Mbps, full duplex. Because all
ports support automatic MDI or MDI-X operation, you can use straight-through cables for all
network connections to PCs or servers, or to other switches or hubs. In addition, it is ideal and
preferred to use straight-through cable for switch-to-switch connections.
Each of these ports supports auto-negotiation, so the optimum transmission mode (half or full
duplex), and the data rate (10, 100, or 1000 Mbps) can be selected automatically. If a device
connected to one of these ports does not support auto-negotiation, the communication mode of
the port can be configured manually.
Combination ports
PowerConnect B-FCX devices contain four combination ports, which are four Small Form Factor
Pluggable (SFP) network interfaces (1F~4F) that are shared with four of the RJ45 ports (ports 1~4).
In the default configuration, if an SFP transceiver is installed in a slot and has a valid link on its
port, the associated RJ45 port is disabled and cannot be used. The switch can also be configured
to force the use of a combination RJ45 port or SFP slot, as required.
