DES-1526
26-Port PoE 10/100Mbps Smart Switch
With 2 Combo 1000BASE-T/SFP Gigabit Connections
The DES-1526 Smart Switch combines 10/100Mbps Ethernet switching with 802.3af standard remote power on network
cabling of up to 100 meters. This switch presents a cost-effective solution for the small and medium business, delivering the
perfect combination of functionality, ease of use and affordable pricing. With integral power sourcing capability and inherent
support including VLAN, Priority Queues, port trunks and simplified management, this switch is ideal PoE choice that offers
security, Quality of Service, low infrastructure cost and easy deployment.

Port Mirroring
The DES-1526 supports port mirroring to assist network
traffic monitoring. Your network administrator can use this
function as a diagnostic tool or debugging feature, especially
when fending off an attack. It enables you to keep close track
of switch performance and alter it, if necessary. Port mirroring
can be managed locally or remotely. Your administrator places
a protocol analyzer on the port receiving the mirrored data to
monitor each segment separately. The analyzer captures and
evaluates the data without affecting the client on the original
port.
