RCHITECTURE
This switch employs a wire-speed, non-blocking switching fabric. This permits
simultaneous wire-speed transport of multiple packets at low latency on all
ports. The switch also features full-duplex capability on all ports, which
effectively doubles the bandwidth of each connection.
This switch uses store-and-forward switching to ensure maximum data integrity.
With store-and-forward switching, the entire packet must be received into a
buffer and checked for validity before being forwarded. This prevents errors
from being propagated throughout the network.

ETWORK
ANAGEMENT
With a comprehensive array of LEDs, the switch provides "at a glance"
monitoring of network and port status. The switch can be managed over the
network with a web browser.
For a detailed description of the management features, refer to the Management
Guide.

All 48 RJ-45 ports (1~48) of the ECS2000-50P switch support the IEEE 802.3at
standard that enables DC power to be supplied to attached devices using wires
in the connecting Ethernet cable. The total PoE power delivered by all ports
cannot exceed the 375 W power budget.
Any PoE-compliant device attached to a port can directly draw power from the
switch over the Ethernet cable without requiring its own separate power source.
This capability gives network administrators centralized power control for
devices such as IP phones and wireless access points, which translates into
greater network availability.
For each attached PoE-compliant device, the switch automatically senses the
load and dynamically supplies the required power. The switch delivers power to a
device using the wire pairs in UTP or STP cable. Any RJ-45 port on the switch can
provide up to 30 W of power, but only 12 ports maximum can deliver 30 W
simultaneously to attached devices without exceeding the switch power budget.
