One-port, rear-panel module.

Connects to 1000BASE-T devices at 1000M/full duplex, 100M/full duplex, 100M/half duplex, and Auto.

Supports Category 5+ or higher cable connections of up to 100 meters.

LED Indicators

The LED indicators of the Switch include Power, Console, Slot2, Giga, Speed, and Link/Act. The following shows the LED indicators for the Switch along with an explanation of each indicator.

Figure 3-11. The LED indicators

Power This indicator on the front panel should be colored amber during the Power-On Self Test (POST). It will light green approximately 2 seconds after the switch is powered on to indicate the ready state of the device. The LED will blink green while downloading new software for the switch, or if the system’s configuration has changed and will light yellow when an error occurs.

Console This indicator is lit green when the switch is being managed via out-of-band/local console management through the RS-232 console port using a straight-through serial cable.

Slot 2 This indicator is lit green when a Gigabit Ethernet slide-in module is present in the rear panel of the Switch.

Giga This indicator is lit green when a link is established. It blinks green when the Gigabit port is active.

100M These indicators are illuminated green when a 100 Mbps device is connected to any of the 24 ports or uplink port. If a 10 Mbps device is connected to any of the 24 ports or uplink port, these LEDs remain dark.

Link/Act These indicators are lit when there is a secure connection (or link) to a device at any of the ports. The LEDs blink whenever there is reception or transmission (i.e. Activity--Act) of data occurring at a port.

DES-3225G specifications

The D-Link DES-3225GF and DES-3225G are both robust Ethernet switches designed to meet the networking needs of small to medium-sized enterprises and organizations. These devices are part of D-Link's comprehensive range of unmanaged layer 2 switches, known for their reliability and ease of use.

The DES-3225GF features a total of 25 Ethernet ports, including 24 10/100Base-TX ports and 1 Gigabit SFP slot, while the DES-3225G also comes with 25 ports but includes 24 10/100/1000 Mbps copper ports. Both models support Auto-MDI/MDI-X for seamless connection setup without the need for crossover cables, simplifying the deployment process.

One of the standout features of these switches is their wire-speed performance that enables high-speed data transfers and efficient traffic management. Each port is designed to provide non-blocking switching, which ensures that the bandwidth is fully utilized without any packet loss. The switches support IEEE 802.3x flow control, which helps to manage data flow and prevent overflow during heavy traffic periods.

The DES-3225GF and DES-3225G offer users a simple yet efficient way to expand their network. With a plug-and-play design, they require minimal configuration, allowing for quick integration into existing network infrastructures. These switches are equipped with a durable chassis, ensuring they can withstand the rigors of a busy IT environment.

Both models boast energy-efficient technologies that comply with IEEE 802.3az, which helps in reducing power consumption during periods of inactivity. By detecting link status and adjusting power accordingly, these switches contribute to a more sustainable networking solution.

In terms of form factor, the DES-3225GF and DES-3225G are rack-mounted, making them suitable for integration into standard network cabinets. This design ensures that the devices can be efficiently managed alongside other network equipment.

For management and security, the switches support features such as VLAN tagging and port security, allowing network administrators to segment traffic and protect the network from unauthorized access. With their sturdy build, innovative features, and straightforward implementation, the D-Link DES-3225GF and DES-3225G are ideal choices for organizations looking to enhance their network performance while keeping costs manageable.
