D-Link DES-1005D/B Product Data Sheet

10/100Mbps Unmanaged Switch

DES-1005D

DES-1005D switch provides 5 auto-sensing
10/100Mbps ports in a palm-sized box. The
switch allows mix and match of Ethernet and
Fast Ethernet in full- and half-duplex modes.

5-Port 10/100Mbps Switch for SOHO

The DES-1005D is an unmanaged 10/100Mbps switch designed to enhance small workgroup performance while
providing a high level of flexibility. Powerful yet easy to use, this device allows users to simply plug any port to
either a 10Mbps or 100Mbps network to multiply bandwidths, boost response time and satisfy heavy load
demands.

5 Auto-sensing 10/100Mbps Ports

The switch comes with 5 10/100Mbps ports, allowing a
small workgroup to flexibly connect to Ethernet ad Fast
Ethernet and integrate. These intelligent ports detect the
network speed and auto-negotiate between 100BASE-TX
and 10BASE-T, as well as between full- and half-duplex.

Flow Control for Secure Transmission

All ports support 802.3x flow control. This function
minimizes dropped packets by sending out collision
signals when the port's receiving buffer is full. Flow
control is available in the full-duplex mode.

Auto-negotiation of MDI/MDIX Cross Over

All ports support auto-negotiation of MDI/MDIX cross
over. This eliminates the need for cross over cables or
uplink ports. Any port can simply plug to a server, a hub or
a switch, using the usual straight-through twisted-pair
cable.

SOHO Plug-and-Play

With 5 plug-and-play ports, the switch is a perfect choice
for the small workgroup to upgrade performance in a
client/server environment. The ports can be connected to
servers in full-duplex, or hubs in half-duplex.

Desktop Power

With low-cost connection per-port, the switch can also be
set up for direct connection from the PCs. This relieves
data bottleneck by giving each workstation a dedicated
bandwidth on the network.

10/100Mbps Network Kit

For network starters, a convenient kit is available for
ready installation. This kit includes a DES-1005D switch,
2 10/100Mbps Fast Ethernet PCI cards, and 2 6-meter
(20-foot) UTP cables.
