Layer 2 Features - D-Link DES-3326SR User Manual

circuit continuously monitors the internal power supply. In the
event of a power interruption, the redundant power supply is
immediately triggered so that the DES-3326SR and connected
devices can continue providing service.
This results in a more reliable network infrastructure and
protects a network from a single failure of a network device
power supply.
The redundant power supply may be purchased with and
included in the original system installation, or may be added to
an existing system at a later time.

Layer 2 Features

•
8.8 Gbps switching fabric capacity
•
Store and forward switching scheme.
•
Full and half-duplex for both 10Mbps and 100Mbps
connections. The
operates at full-duplex only. Full-duplex allows the switch
port to simultaneously transmit and receive data, and only
works with connections to full-duplex capable end stations
and switches. Connections to hubs must take place at half-
duplex.
•
Supports IEEE 802.3x flow control for full-duplex mode
ports.
•
Supports Back-pressure flow control for half-duplex mode
ports.
•
Auto-polarity detection and correction of incorrect polarity
on the transmit and receive twisted-pair at each port.
•
IEEE 802.3z compliant for all Gigabit ports (optional
module).
