EGS7228P
24-Port Gigabit PoE+
Layer 2 Managed Switch
with 4 Dual-Speed SFP
Cost-effective, simple-to-use networking solutions
for small-to-medium businesses
The EGS7228P is a full featured Gigabit Ethernet switch with comprehensive
Layer 2 switching capabilities and PoE+ support. It provides 24 Gigabit ports
that support IEEE802.3at/af PoE+, and 4 SFP slots for ber transceivering
that can extend the reach of the network beyond the limitation of Ethernet
cabling. With rich Layer 2 management features, the EGS7228P allows quick
deployment and simplied maintenance as well as seamless upgrades, making
it the ideal networking solution for businesses looking for the best combination
of features, performance and value.
Equipped with Rich Layer 2 Features
The EnGenius Layer 2 switch includes IGMP Snooping, MLD Snooping, Port Mirroring,
Rapid Spanning Tree, Multiple Spanning Tree, Spanning Tree, VLAN group, Voice VLAN,
ACL, 802.1X port security, SNMP v1/v2c/v3 and IEEE802.3ad Link Aggregation Control
Protocol (LACP). The EGS7228P includes 24 Gigabit PoE (10/100/1000 Mbps) ports and
four SFP (copper/hot-swappable small form-factor pluggable) Gigabit ports for optional ber
connectivity. IT managers or VARs who are expanding network deployments for businesses,
schools, resorts and hotels, or other expansive venues can expect superior performance
and reliability at a price point that is much more attractive than from larger, more enterprisefocused network brands.
This high-performing switch also features a non-blocking wire-speed architecture with a
56 Gbps switching capacity for maximum data throughput. The IEEE 802.3x Flow Control
function allows servers to directly connect to the switch for fast, reliable data transfer. Network
maintenance features include Spanning Tree and Cable Diagnostics.
Easy Network Management and Visibility
This EnGenius Layer 2 Switch is designed for easy network management and can quickly
be added to an existing rack of other branded L2 and L3 switches. Conguring the switch is
made through an intuitive and user-friendly Web interface for quick and easy management.
The EnGenius L2 switch also includes SNMP (v1, v2 and v3) to collect and track data to
monitor network health, manage devices, and more easily enforce critical IT controls and
policies. The switch’s Link Layer Discovery Protocol (LLDP) feature allows it and other network
devices connected to it to announce and display their identity and capabilities on the local
network, which helps IT managers better manage, troubleshoot or correct issues that may
arise on the network.

VLAN and Voice VLAN
The EGS7228P provides support 802.1Q VLANs for improved convergence and
bandwidth utilization. The switch automates the process of setting up VoIP devices on
a network. Voice VLAN guarantees clear quality and efcient transmission for all voice
communications. VLANs also provide a means of securing each broadcast domain,
segregating them from each other. VLANs can be congured to segment departmental
resources. VLANs implemented on an SMB network help to restrict access to sensitive
information from one department to another.
Multicast Support
The EGS7228P supports IGMP Snooping, MLD Snooping, and VLAN for multicast
applications. By passively snooping IGMP packets transferred between the switch
and the IP multicast host, registration information is recorded and sorted into multicast
groups. The switch can then intelligently forward trafc to only those ports that
request multicast trafc. MLD Snooping enhances efciency in selective distribution by
forwarding IPv6 multicast data to receiving ports, rather than ooding all ports in a VLAN.
IGMPv1—Dened in RFC 1112. An explicit join message is sent to the switch,
but a timeout is used to determine when hosts leave a group.
IGMPv2—Dened in RFC 2236. Adds an explicit leave message to the join
message so that the switch can more easily determine when a group has no
interested listeners on a LAN.
IGMPv3—Dened in RFC 3376. Support for a single source of content for a
multicast group.
QoS for Smoother Video Conferences and Clearer Phone Calls
Priority queueing ensures high-priority trafc gets delivered efciently, even during
congestion from high trafc bursts. The ability to prioritize trafc ensures quality of
latency-sensitive services and applications despite increasing trafc loads. For mission
critical environments, the EGS7228P supports 802.1D, 802.1w and 802.1s Spanning
Tree Protocols (STP). STP allows you to congure the switch with a redundant backup
bridge path, so transmission and reception of packets can be guaranteed in the event
of any failed switch on the network. To help streamline networks, 802.1p Priority Tagging
places a priority tag in a specied frame placing it in a priority queue once received and
enabling it to be prioritized ahead of other frames. IEEE 802.1p enables administrators
to assign and designate trafc priority. This process helps applications such as VoIP and
video conferencing to be delivered clear and jitter-free.
Making the Network More Secure
The EGS7228P also supports 802.1X port-based authentication, so IT managers can
authenticate clients via external RADIUS servers. In addition, the Access Control List
(ACL) feature enhances network security and protects the network by screening trafc
from unauthorized MAC or IP addresses.
Energy Saving
This EnGenius Layer 2 Switch is capable of conserving power without sacricing
operational performance. With the Energy Efcient Ethernet (EEE) standard, the network
will automatically decrease its power usage when trafc is low with no setup required.
The PoE Management feature lets IT managers control the PoE on each port so that
unnecessary power consumption can be saved during off hours. The switch can also
detect the length of connected cables to automatically reduce power usage on shorter
cable connections.
Power over Ethernet (PoE)
With a total power budget of 185 Watts for the EGS7228P, customers can choose to
plug in up to 24 802.3at/af IP-based devices. Power-over-Ethernet (PoE) optimizes the
installation and power management of network devices such as wireless Access Points
(APs), Voice over IP (VoIP) phones, and IP-based surveillance cameras. In addition,
the EGS7228P’s Power-over- Ethernet (IEEE 802.3at/af) capabilities reduce installation
time and costs for many new network productivity devices. Free your wireless AP
deployments and IP cameras from the restrictions of power outlet proximity using a
standard Cat 5 cable.
