A switch is a device with which it is possible to connect computers into a (local area) network, provided your computers all have an appropriate networking device installed. Switches can be daisy chained to form larger networks and come in managed and unmanaged variaties. The unmanaged versions generally cannot filter data and will forward any data that is fed into them, so they are better suited for small networks. Switches are easy to set up (just plug in the network cables) and allow you to share printers, storage space and other network resources with your entire home or office network.

Best fit for SMB & Campus for Convergence Network
ZyXEL ES-2048 is an entry-level, managed L2 Fast Ethernet Switch, and specially designed for SMB or Campus to empower multi-tasks in today's dynamic network environment requiring capability over security, QoS and network management. Complete product portfolio with optimized port configuration (26/50 port), embedded two dual-personality GbE ports and Power over Ethernet (PoE) can easily find solution and fit in any network very easily.

High-Security Network Edge
The ES-2048 features wide range security functions to prevent unauthorized data access. 256 Static VLAN entry enables complicated VLANs portfolio for policy management. Full range 4K VLAN (4K PVID) are equipped as well. Besides central access authentication by 802.1x, it can further assigns VLAN and bandwidth per pre-defined attribute for valid user which greatly lifts flexibility over network management. In addition, extra support of MAC filtering, MAC freezing and Specific MAC forwarding, allow the network administrator to set security policy toward device MAC address. The ES-2048 is designed to offer comprehensive security features for enforcing security policies to the edge.

Intelligent Traffic Prioritization for Multi-Services
Multiple priority queues and scheduling mechanism, makes the ES-2048 easy to perform traffic prioritizing for delay-service applications. You can also customize DSCP settings to provide an end-to-end QoS environment. MVR ensures efficient transmission of multicasting stream on the network-wide multicast VLAN. For bandwidth management, the ES-2048 supports bandwidth increment of 64Kbps to give different bandwidth allocations. Moreover, with broadcast storm control, network can limit the broadcast packets once over pre-defined threshold which prevents the network outrage.

Industry Standard-based Network Management
Managing the ES-2048 is simple through its iStacking™, SNMP, Web, telnet and RS-232 support. iStackingTM, ZyXEL-exclusive clustering technology, allows administrators to manage up to 24 switches with one single IP. In addition, IT staff may opt for Web, CLI (Command Line Interface) or text-based configuration for their convenience and even encrypt the instructions using SSHv1/v2 and SSL. Thanks to these sophisticated functionalities, the IT staff is able to build a highly secure and efficient corporate network with minimum effort.

Installment Freedom by Power over Ethernet
The ES-2024PWR supports IEEE802.3af Power over Ethernet (PoE) to ease the installment in challenging space, such as ceiling or top of wall, Device compliant with IEEE802.3af, like WLAN AP, IP surveillance camera, etc, can get powered Ethernet connectivity through just single Cat-5 cable, with up to 100 meters of successful link distance. There is no need to use extra power adapter and you can walk away from the headache of how to set up the power line to devices. In addition, ES-2024PWR supports intelligent power management via web GUI. You can set the priority levels of power-feeding over different ports to get the best use of power resource.

Management features
Switch type*
What switch device has, managed or unmanaged.
Switch layer
A network switch is a computer networking device that links networking segments. A switch has different layers, such as layer 2 (a network bridge, operating at the data link layer, interconnecting a small number of devices) and layer 4 (can act as a firewall, amongst other things).
Quality of Service (QoS) support
Ports & interfaces
Basic switching RJ-45 Ethernet ports quantity*
The number of basic switching RJ-45 Ethernet ports (sockets).
Console port
Networking standards*
The way in which the network is working, e.g. IEEE 802.11a, IEEE 802.11b, IEEE 802.11g.
IEEE 802.1d, IEEE 802.1p, IEEE 802.1Q, IEEE 802.1w, IEEE 802.1x, IEEE 802.3, IEEE 802.3ad, IEEE 802.3af, IEEE 802.3u, IEEE 802.3x, IEEE 802.3z
Full duplex
A full-duplex system allows communication in both directions, and unlike half-duplex, allows this to happen simultaneously.
Link aggregation
Flow control support
Port mirroring
Data transmission
MAC address table*
The MAC address is the 'Media Access Control Address'. It is a unique address given to a network interface controller (NIC) in a device. A MAC address table shows the addresses in a table format.
16000 entries
Switching capacity*
The data transfer capacity of the switch per second.
13.6 Gbit/s
Static port security
MAC address filtering
Security access control method whereby the 48-bit address assigned to each network card is used to determine access to the network. MAC addresses are uniquely assigned to each card, so using MAC filtering on a network permits and denies network access to specific devices through the use of blacklists and whitelists.
Power consumption (typical) *
Amount of power consumed by this model, often expressed in watts (W). Typical values that manufacturers give are power consumption when off, standby/suspended mode, typical use, maximum usage.
60 W
