Figure 2-5. PowerConnect 2724 Front Panel On the front panel there are 24 ports which are numbered 1 to 24, top down and left to right. On each port there are LEDs to indicate the port status. There are two SFP (Small Form-Factor Plugable) ports, designated as ports 23 and 24, for fiber connection. The two combo ports are logical ports with two physical connections: • An RJ-45 connection for Twisted Pair (TP) copper cabling • An SFP port for swappable optical transceiver, which offers high-speed 1000BASE-SX or 1000BASE-LX connection. NOTE: Only one of the two physical connections of a combo port can be used at any one time. Port features and port controls are determined by the physical connection used. The system automatically detects the media used on a combo port, and utilizes the information in all the control interfaces. NOTE: The system can switch from the RJ-45 to the SFP (or vice versa) without resetting the device. If both RJ-45 and SFP ports are present, the SFP port will be the active port, whereas the RJ-45 port will be disabled. On the left side of the front panel is the Managed Mode LED which indicates the Ethernet switch operational status. The Power LED on the front panel indicates whether the device is powered on or not. A Managed Mode push-button, located on the far right side on the front panel, restores the device's default settings configuration. Figure 2-6. PowerConnect 2724 Back Panel 17

PowerConnect 2724 Front Panel
On the front panel there are 24 ports which are numbered 1 to 24, top down and left to right. On
each port there are LEDs to indicate the port status. There are two SFP (Small Form-Factor
Plugable) ports, designated as ports 23 and 24, for fiber connection. The two combo ports are
logical ports with two physical connections:
•
An RJ-45 connection for Twisted Pair (TP) copper cabling
•
An SFP port for swappable optical transceiver, which offers high-speed 1000BASE-SX or
1000BASE-LX connection.
NOTE:
Only one of the two physical connections of a combo port can be used at any one time. Port
features and port controls are determined by the physical connection used. The system automatically
detects the media used on a combo port, and utilizes the information in all the control interfaces.
NOTE:
The system can switch from the RJ-45 to the SFP (or vice versa) without resetting the device. If
both RJ-45 and SFP ports are present, the SFP port will be the active port, whereas the RJ-45 port will be
disabled.
On the left side of the front panel is the Managed Mode LED which indicates the Ethernet switch
operational status. The Power LED on the front panel indicates whether the device is powered on
or not. A Managed Mode push-button, located on the far right side on the front panel, restores the
device’s default settings configuration.
