§1. PRODUCT DESCRIPTION
Dualcomm’spatent pending 5-Port 10/100base-T LAN Switch TAP (DCSW-
1005PT/DCSW-1005) can be used as both an 10/100Base-T Ethernet switch and a
network TAP (Test Access Point) device. Specifically, it offers several unique features
to better meet your network application needs, which include:
•“Power over Ethernet" Inline Power Pass-Through (DCSW-1005PT Only)
DCSW-1005PT implements a set of two ports for Power-over-Ethernet (PoE) inline
power pass-through, which provides a low cost solution to "expand" a PoE uplink
port into four downstream ports, one of which is capable of receiving the inline
power from the uplink cable to power a connected PD (e.g. an PoE enabled IP phone).
•Port-Mirroring
DCSW-1005/DCSW-1005PT offers a unique and low cost solution for capturing and
monitoring network traffic by means of Port-Mirroring. Port-Mirroring used to be a
feature typically found only in much more expensive managed switches requiring a
series of software configurations, but DCSW-1005/DCSW-1005PT makes it plug and
play and hassle free without going over your budget.
•USB Powered
DCSW-1005/DCSW-1005PT is designed to be conveniently powered by any USB port
of a computer so that no extra AC/DC power adapter is required and no AC outlet is
needed to get this device powered!

§3. FRONT PANEL (LEDs)
DCSW-1005/DCSW-1005PT Switch TAP includes following LED indicators on the front
panel:
•Power LED: This green LED is tuned on when the device receives external input
power properly.
• Port Status LEDs: Each port is provided with a green LED to indicate link/activity
status of the port as defined below:
Link/A t: Solid = linked-Up; Blinking = Activity
§4. REAL PANEL (RJ45 JACKS & DC POWER JACK
DCSW-1005/DCSW-1005PT provides five (5) 10/100Base-T ports that support auto-
negotiation and auto MDI-X. Each port operates as a standard Ethernet switch port
to receive and forward packets.

DCSW-1005/DCSW-1005PT can be used as an aggregation network TAP, in which a
copy of both outgoing and incoming packets associated with Port 1 (Target Port) is
forwarded to Port 5 (Monitor Port). Such a port-mirroring mechanism is hardware-
configured and therefore no software setup is necessary.
DCSW-1005/DCSW-1005PT further implements Port 1 and Port 2 for facilitating PoE
inline power pass through between these two ports. When Port 1 is connected with
an active Ethernet uplink with PoE inline power, the inline power is coupled to Port 2
to supply power to a powered device (PD) that is connected to Port 2. In the same
way, Port 1 also can receives inline power that is passed through Port 2 when Port 2
is connected with a PoE enabled uplink.
