LEDs indicate establishment of Gigabit link

Supports Variety of Authentication Functions Permitting Only Authorized Users to Connect

The BS-POE-G21M supports IEEE 802.1X/EAP authentication,which when used with a RADIUS server allows only users with proper access to connect to the network.
Also supported are Web authentication and MAC address authentication requiring no supplicant.

A Variety of Qos (Quality of Service)Functions to Control Signal Priority

Today's office networks carry a mix of widely differing applications,necessitating various QoS functins to distinguish the relative importance of the transmissions.The BS-POE-G21M provides four levels of QoS based on the IEEE 802.1 standard,while also supporting DSCP/IP Precedence.These functions can be used to suit any particular need.

Reduce Energy Consumption with Low Power Idle Mode

In addition to the energy-saving adjustments based on link status and cable length,the Low Power ldle mode cuts energy consumption at times when there is no data being transmitted.Use of Power ldle mode can cut energy consumption up to 29% when all ports are in use,and up to 38% when no ports are in use.

UL60950-1 safety standard certified

As proof of design safety by a third-party organization,these switches are UL-listed (UL60950-10),approved by Underwriters Laboratories.

Conveniently designed to meet a variety of installation needs

PoE Profiler Function Checks Wasted PoE Power

Turns PoE on and off at specified times or days of the week.Cuts wasteful power use.

The PoE Profiler function turns the PoE power supply on and off at specified times or days of the week.This makes it easy to reduce wasteful power use by stopping PoE supplies,for example at night and days off,when wireless access points are not used much.

Swtiches Feature a Variety of Functions

-Compliant with IEEE802.3ab (1000BASE-T)/IEEE802.3u (100BASE-TX)/IEEE802.3 (10BASE-T)standards

AC Cable Hook Prevents Disconnection

Optimal for Configuring Secure Networks

The switches support the "EAPOL (IEEE 802.1X frame) pass"security function required in MAC-based IEEE 802.1X authentication environments.This is Optimal for Configuring Secure Networks.Also supported is the "BDPU pass" function required for redundant networks.

No More Messy Outlets

The internal power supply means no AC adapters are needed,so normally messy outlets are now tidy and clear.

Automatically Distinguishes Between Straight and Crossover Cables

The units feature Auto-MDIX to automatically distinguish between connected straight and crossover LAN cables.This prevents problems from mistakes in connecting,thus helping to reduce repair and maintenance costs.

RoHS Compliant

This product complies with the "RoHS D irective,"a directive implemented in the EU since July 2006 that places restrictions on the use of specified hazardous substances in manufacturing electronic equipment.
