The D-Link DGS-1250 Series Smart Managed Switches are the latest generation of switches
to provide increased Power over Ethernet (PoE) output, high port density, multiple
management interfaces, and advanced Layer 2 features. With all of these features combined,
the DGS-1250 Series provides a cost-ecient and exible solution for expanding any business
network.
Seamless Integration
The DGS-1250 Series includes a wide range of port and media types. All models in the
DGS-1250 Series feature four 10G SFP+ ports, allowing you to choose the most suitable
media type for your requirements. All DGS-1250 Series PoE switches include support for
IEEE 802.3af/at and higher power budgets, allowing more PoE devices to be powered
by the switch and for devices to be installed in remote locations without immediate
access to power outlets. Furthermore, the DGS-1250-28XMP and DGS-1250-52XMP
can supply PoE power up to 370 W providing even more power for connected devices.
Advanced Features
The DGS-1250 Series comes equipped with a complete lineup of L2 features, including
IGMP snooping, port mirroring, Spanning Tree Protocol (STP), and Link Aggregation Control
Protocol (LACP). The IEEE 802.3x Flow Control function allows servers to directly connect
to the switch for fast, reliable data transfers. The DGS-1250 Series also supports advanced
features such as static routing, which allow network administrators to divide the network
into VLANs, increasing network eciency. Network maintenance features include loopback
detection and cable diagnostics. Loopback detection signicantly speeds up troubleshooting
by automatically detecting and shutting down switching loops. The cable diagnostics feature,
designed primarily for administrators and customer service representatives, determines the
cable quality and quickly discovers errors, allowing for swift diagnostics and maintenance.
DGS-1250 Series Smart Managed Switches
Surveillance Mode
The DGS-1250 Series supports Auto Voice VLAN and Surveillance Mode, which
allows voice and video trac to be automatically identied and handled
dierently than regular network trac. Auto Voice VLAN detects Voice over
IP (VoIP) trac and automatically segments it from the rest of the network,
adding a layer of isolation and allowing Quality of Service (QoS) to be applied.
Surveillance Mode detects compatible ONVIF cameras and places them in a
surveillance VLAN, allowing a single switch to be used for voice, video, and data,
removing the need for dedicated hardware and reducing maintenance costs.
Surveillance Mode also includes its own Web UI, making surveillance features
easily accessible and simplifying management of your surveillance network.
Advanced Access Control
D-Link’s innovative Safeguard Engine helps to protect the switches against
trac ooding caused by malicious attacks. The DGS-1250 Series supports
802.1X port-based authentication, allowing clients to be authenticated
through external RADIUS servers. The Access Control List (ACL) feature helps
to enhance network security and helps to protect the internal IT network. The
DGS-1250 Series also features Address Resolution Protocol (ARP) spoong
prevention, which helps to provide protection from attacks on the network
that could allow an intruder to sni data frames, modify trac, or bring trac
to a halt altogether by sending fake ARP messages. To help prevent ARP
spoong attacks, the switch uses packet control ACLs to block invalid packets
that contain fake ARP messages. The DHCP server screening lters DHCP
replies on unauthorized ports to prevent them from being assigned an IP
address.
Versatile Management
The DGS-1250 Series comes with the D-Link Network Assistant (DNA)
utility that enables administrators to remotely control their network
down to the port level. The D-Link Network Assistant utility furthermore
allows customers to easily discover multiple D-Link Smart Managed
Switches within the same L2 network segment and display them on-
screen for instant access. With this utility, users do not need to change
the IP address of their PC. This allows for simultaneous conguration and
setup of all discovered devices, including password changes and rmware
upgrades. The DGS-1250 Series supports Command Line Interface (CLI)
through console port. SNMP is also supported which allows for the central
management of network assets, remote conguration, and logging functions.
6kV Surge Protection
The DGS-1250 Series switches feature built-in 6kV surge protection on all PoE
and non-PoE Ethernet access ports. This helps protect the switches against
sudden electrical surges such as lightning strikes or unstable electrical current.
Built-in 6kV surge protection helps reduce the chances of equipment being
damaged from electrical surges, and eectively lowers maintenance costs by
minimizing the need for expensive equipment repairs or replacement.
Lifetime Warranty
D-Link oers a Lifetime Warranty and Next Business Day (NBD) hardware
replacement for the DGS-1250 Series Smart Managed Switches to further its
commitment to product quality and long-term customer condence.
