Chapter 1 Overview
1.1 Introduction
The ADAM-6521 series consists of industrial-grade 10/100 Mbps Ether-
net switches with fiber ports that make it possible to expand industrial
networks fast and cost-effectively. In addition to four 10/100 Mbps Ether-
net ports with RJ-45 connector, ADAM-6521 also provide one multi-
mode fiber optic port, while ADAM-6521S provides one single-mode
fiber optic port with a SC-type connector. Using fiber optics, you can pre-
vent noise from interfering with your system and support high-speed (100
Mbps) and long-distance (ADAM-6521: 2km; ADAM-6521/ST: 2km;
ADAM-6521S: 15km) transmissions.
ADAM-6521 modules can accept a input voltage range from +10 to 30
VDC to the terminal block. In addition, the operating temperature is from
-10 to 65° C. The above functions make the ADAM-6521 modules more
stable and reliable, so they are especially suitable for industrial environ-
ments that require Ethernet networking, such as: semiconductor factories,
warehouses, industrial conveyer systems and more.
High-Speed Transmission
ADAM-6521 modules have a switch controller that can automatically
sense transmission speeds (10/100 Mbps). The RJ-45 interface can also
be auto-detected, so MDI or MDI-X is automatically selected and a cross-
over cable is not required. All ports have memory buffers that support the
store-and-forward mechanism. This assures that data is properly transmit-
ted.
Flexible Mounting
Due to its versatility and innovative design, ADAM-6521 modules can be
fixed in three ways: DIN rail, panel and piggyback mounting.
Advanced Protection for Power line
The power line of ADAM-6521 modules supports up to 3000 VDC surge
protection (EFT), which secure equipment against unregulated voltage
and make systems safer and more reliable.

3 Chapter1
Easy Troubleshooting
There are 6 LED indicators supplied that aid troubleshooting for ADAM-
6521 modules. Each port has a pair of LEDs to indicate link status and
port activity. This makes it easy to monitor collisions, link status, power
failure and data reception for on-site diagnostics.

2.3 Mounting the Module
2.3.1 Choosing a Mounting Method
Due to its versatile and innovative design, the ADAM-6521 modules can
be:
• Fixed to a wall
• Fixed to a DIN Rail
• Piggyback Stacked
Panel Mounting
ADAM-6521 modules can be attached to a wall using the included brack-
ets. Each bracket comes with four screws; first attach the bracket to the
bottom of the ADAM-6521 module. Next, screw the bracket to the wall.
Figure 2.4: Wall Mounting

11 Chapter2
DIN-rail Mounting
You can mount ADAM-6521 modules on a standard 35 mm DIN-rail.
First, use two screws to attach the DIN-rail bracket to the ADAM mod-
ule. Because ADAM-6521 modules use special hex head slotted shoulder
screws, the tops of the screws will be even with the front of the module.
Snap the module onto the DIN-rail.
Figure 2.5: Attaching DIN Rail Bracket
Piggyback Stack
Several ADAM-6521modules can be stacked as seen in the figure below.
Figure 2.6: Piggyback Stacking

ADAM-6521 Series User Manual 12
2.4 Connections
2.4.1 Connection to the Devices
ADAM-6521 modules have one fiber and four RJ-45 ports. Each of the
switch's twisted-pair ports can be used to connect a station or other
devices. Use a straight-through twisted-pair cable with RJ-45 connectors
on both ends. The twisted-pair cable extended from a twisted-pair port is
called a “twisted-pair segment,” and it can be up to 100 meters long. You
can connect any RJ-45 (MDI-X) station port on the switch to any device
that uses a standard network interface such as a workstation or server.
2.4.2 Connection to Other Hubs or Switches
ADAM-6521 modules have four RJ-45 ports that support connection to
10Mbps Ethernet or 100Mbps Fast Ethernet, and half or full-duplex oper-
ation. ADAM-6521 modules can be connected to other hubs or switches
via a two-pair straight-through cable or crossover cable. The connection
can be made from any port on ADAM-6521 modules (MDI-X) to other
hubs or switches either by either an MDI-X port or uplink MDI port.
ADAM-6521 modules support auto crossover to make networking easier
and more flexible. You can connect any RJ-45 (MDI-X) station port on
the switch to any device such as a switch or a bridge or router .
2.4.3 Connection to a Fiber Network
Connect to a fiber network segment with a two strand fiber. All you need
to remember is to connect the Tx (transmit) port of device I to the Rx
(receive) port of device II, and the Rx (receive) port of device I to the Tx
(transmit) port of device II.
With fiber optic transmissions you can reach speeds up to 100 Mbps, you
can block all noise interference from the system, and the transmission dis-
tance goes up to 2km for multi-mode fiber, or 15km for single-mode
fiber.
Note Please use the dust cover that was shipped
with your ADAM-6521 modules on the fiber-optic
port if it is not being used.

13 Chapter2
2.4.4 Power Connection
You should take the following steps to connect ADAM-6521 modules to
a power supply.
1. Connect the power cable to a 2-pin connector.
2. Connect the power cable to a power adapter.
