CN2600 Series Hardware Installation
2-2
Desktop
Place your CN2600 on a clean, flat, well-ventilated desktop. For better ventilation, attach the 4 pads from the
desktop kit to the bottom of the unit, and leave some space between the CN2600 and other equipment. Do not
place equipment or objects on top of the unit, as this might damage the server.
Rackmount
The CN2600 is designed to be mounted on a standard 19-inch rack. Use the enclosed pair of L-shaped metal
brackets and screws to fasten your CN2600 to the rack cabinet. Each L-shaped bracket has 6 holes, leaving two
outer or inner holes available for other uses. You have two options. You can lock either the front or rear panel
of the CN2600 to the front of the rack. Locking the front panel is shown in the following figure.
Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your CN2600.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious d
amage to your
equipment.
Temperature Caution!
Be careful when handling the CN2600. When plugged in, the CN2600’s internal components generate heat, and
consequently the board may feel hot to the touch.
You should also observe the following common wiring rules:
•Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must
cross, make sure the wires are perpendicular at the intersection point.
NOTE
Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid interference,
wires with different signal characteristics should be routed separately.

CN2600 Series Hardware Installation
2-3
•You can use the type of signal transmitted through a wire to determine which wires should be kept separate.
The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.
•Keep input wiring and output wiring separate.
•Where necessary, it is strongly advised that you label wiring to all devices in the system.
Connecting the CN2600-8/16’s Power
Connect the CN2600’s 100-240 VAC power line to its AC connector. If the power is properly supplied, the
“Ready” LED will show a solid red color until the system is ready, at which time the color changes to green.
WARNING
CL 1.7.9
Isolation of multiple power sources & CL 3.4.11 Multiple power sources:
Where there is more than one connection supplying HAZARDOUS VOLTAGES or HAZARDOUS ENERGY LEVELS
to equipment, a prominent marking, located close to the entry point provided for a SERVICE PERSON to gain
access to the hazardous parts, shall be provided to indicate which disconnect device or devices isolate the
equipment completely and which disconnect devices can be used to isolate each section of the equipment.
CAUTION: This server may
be shipped with multiple power supplies that require more than one connector to AC
mains. The AC power cords are considered to be the mains disconnect device for the server; always disconnect
power supply cords before opening up or servicing the server.
Connecting the CN2600-8/16-HV’s Power
To connect the CN2600-8/16-HV’s power cord with its terminal block, follow the steps given below:
1. Loosen the screws on the V+ and V- terminals of the CN2600-8/16-HV’s terminal block.
2. Connect the power cord’s VDC wire to the terminal block’s V+ terminal, and the power cord’s DC power
ground wire to the terminal block’s V- terminal, and then tighten the terminal block screws. (Note: the
CN2600-8/16-HV can still operate even if the DC and DC power ground are reversed.)
If the power is properly supplied, the “Ready” LED will show a solid red color until the system is ready, at which
time the “Ready” LED will change to a green color.
NOTE
You should use 8 kg

Grounding the CN2600-8/16-HV
Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the
ground connection from the ground screw to the grounding surface prior to connecting devices. The shielded
ground (sometimes called protected ground) contact is the second contact from the right of the 5-pin power
terminal block connector located on the rear panel of the CN2600-8/16-HV. Connect the SG wire to the Earth
ground
ATTENTION
This product is intended to be
mounted to a well-grounded mounting surface such as a metal panel.
Connecting to the Network
Connect one end of the Ethernet cable to the CN2600’s 10/100M Ethernet port and the other end of the cable
to the Ethernet network. There are 2 LED indicators located on the top left and right corners of the Ethernet
connector. If the cable is properly connected, the CN2600 will indicate a valid connection to the Ethernet in the
following ways:
The top right corner LED indicator maintains a solid green color w
hen the cable is properly
connected to a 100 Mbps Ethernet network.
The top left corner LED indicator maintains a solid orange color when the cable is properly
connected to a 10 Mbps Ethernet network.
Connecting to a Serial Device
Use appropriately wired serial data cables to connect serial devices to the CN2600’s serial ports.
Connecting to the Console Port
A console is a combination of keyboard and monitor that is used to configure settings and monitor the status
of your system. The console port can be used if a network is unavailable, or you do not know the CN2600’s IP
address. To connect to the console port, use a PC running UNIX, or a PC with terminal emulation software (e.g.,
HyperTerminal or PComm by Moxa; parameter settings are: baudrate = 115200 bps, parity check = None, data
bits = 8, stop bits = 1, terminal type = VT100). Use an RJ45-to-DB25 or RJ45-to-DB9 cable to connect the
terminal to the console port.

Adjustable Pull High/Low Resistors for the
RS-485 Port
In some critical environments, you may need to add termination resistors to prevent the reflection of serial
signals. When using termination resistors, it is important to set the pull high/low resistors correctly so that the
electrical signal is not corrupted. The CN2600 uses jumper settings or DIP switches to set the pull high/low
resistor values for each serial port.
To set the pull high/low resistors to 150 KΩ, make sure both of the assigned DIP switches are in the OFF
position. This is the default setting.
To set the pull high/low resistors to 1 KΩ, make sure both of the assigned DIP switches are in the ON position.
ATTENTION
Do not use the 1 KΩ setting on the CN26
50 when using the RS-232 interface. Doing so will degrade the RS-
232
signals, shorten the maximum allowed communication distance, and the Rx LED
may light up.

Static and Dynamic IP Addresses
Determine whether your CN2600 needs to use a static IP or dynamic IP address (either DHCP or BOOTP/PPPoE
application).
•If your CN2600 terminal server is used in a static IP environment, you will assign a specific IP
address using one of the tools described in this chapter.
•If your CN2600 terminal server is used in a dynamic IP environment, the IP address will be assigned
automatically from over the network. In this case, set the IP configuration mode to DHCP, DHCP/BOOTP,
BOOTP, or PPPoE.
ATTENTION
Consult your network administrator on how to reserve a fixed IP address for your CN2600 in the MAC
-IP
mapping table when using a DHCP Server or BOOTP Server. For most applications, you should assign a fixed
IP address to your CN2600.
Factory Default IP Address
The CN2600 is configured with the following default private IP addresses:
192.168.126.254 and 192.168.127.254
Note that IP addresses that begin with “192.168” are referred to as private IP addresses. Devices configured
with a private IP address are not directly accessible from a public network. For example, you would not be able
to ping a device with a private IP address from an outside Internet connection. If your application requires
sending data over a public network, such as the Internet, your CN2600 will need a valid public IP address,
which can be leased from a local ISP.
Configuration Options
Terminal Server Search Utility
You may configure your CN2600 with the bundled NPort Search Utility for Windows. Please refer to Chapter 9
Software Installation/Configuration, for details on how to install and use Terminal Server Search Utility.
Web Console
You may configure your CN2600 using a standard web browser. Please refer to Chapter 5, Configuration with
the Web console, for details on how to access and use the CN2600 web console.
LCM Console/Front Panel
The CN2600 only gives you the option to configure some settings through the front panel, also known as the
LCM (Liquid Crystal Module) console. The LCM console can be configured for read-only or writeable access.
Read-only access allows settings to be viewed but not changed. Factory default settings are for writeable
access, where configuration is allowed through the LCM console.
NOTE
The wide temperature model does not have an LCM Display panel and push buttons. The LCM description below
applies only to standard temperature models.

ATTENTION
If a password has been enabled for the CN2600 console and the LCM console is configured for writeable status,
the LCM console will require you to enter the password before allowing you access. The password will not be
required if the LCM console
is configured for read-only access.

ARP
You may use the ARP (Address Resolution Protocol) command to set up an IP address for your CN2600. The
ARP command tells your computer to associate the CN2600’s MAC address with an IP address. Afterwards, use
Telnet to access the CN2600 and its IP address will be reconfigured.
ATTENTION
In order to use the
ARP setup method, both your computer and the CN2600 must be connected to the same
LAN. Alternatively, you may use a cross
-
over Ethernet cable to connect the CN2600 directly to your computer’s
Ethernet card. Before executing the ARP command, your CN2600 must be configured with the factory default
IP address (192.168.127.254) and your computer and the CN2600 must be on the same subnet.
To use ARP to configure the IP address, complete the following:
9. Obtain a valid IP address for your CN2600 from your network administrator.
10. Obtain your CN2600’s MAC address from the label on the bottom panel.

11. Execute the arp -s command from your computer’s MS-DOS prompt as follows:
arp -s <IP address> <MAC address>
For example,
C:\>arp -s 192.168.200.100 00-90-E8-04-00-11
12. Next, execute a special Telnet command by entering the following exactly:
telnet 192.168.200.100 6000
When you enter this command, a Connect failed message will appear, as shown below.
13. After the CN2600 reboots, its IP address will assigned to the new address and you can reconnect using
Telnet to verify that the update was successful.
Telnet Console
Depending on how your computer and network are configured, you may find it convenient to use network
