FCC Warning Statement:
The Cyclades-PC400 has been tested and found to comply with the limits for Class A digital devices, pursuant to
Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in accordance with the Installation Manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause
harmful interference in which case the user is required to correct the problem at his or her own expense.
Canadian DOC Notice:
The Cyclades-PC400 does not exceed the Class A limits for radio noise emissions from digital apparatus set out
in the Radio Interference Regulations of the Canadian Department of Communications.
Le Cyclades-PC400 n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils
numériques de la classe A prescrites dans le règlement sur le brouillage radioélectrique edicté par le Ministère
des Communications du Canada.

CHAPTER 1 WHAT IS IN THE BOX
Two Cyclades-PC400 models are available: one with DSPs (for analog modem connections) and one without
them (for digital connections). One cable per channel is provided for connection of the board to a T1/E1 line. A
diskette containing the PC400 driver is also included, and its use is described in chapter 3.

6Chapter 2 Hardware Installation
CHAPTER 2 HARDWARE INSTALLATION
The body carries static electricity and if the person installing the PC400 is not correctly grounded, the board
could suffer irreversible damage. Please follow the instructions outlined below carefully to avoid harming the
board.
Step One:
Unplug the computer and remove all cables connecting the computer to other devices.
Step Two:
Carry the computer to a workbench or table where an anti-static wrist-strap is available. It is highly
recommended that a wrist-strap be used. Remove the computer cover, exposing the boards inside. Attach the
wrist-strap to your wrist.
.

7Chapter 2 Hardware Installation
Step Three:
Be careful to not touch any components inside the computer’s chassis, as they also can be damaged by static
electricity. Confirm that the wrist-strap is grounded. If a wrist-strap is not available, touch a non-painted,
metallic part of a computer plugged in to a wall outlet to remove any excess charge. Remove the board from its
anti-static packaging, being careful to not touch the components or metal parts of the board.
.

8Chapter 2 Hardware Installation
Step Four:
Insert the board carefully into any unused PCI slot so that the external connector is aligned with the opening in
the back of the computer. Make sure that the board does not touch any metallic parts of the interior of the
computer. The second bracket of models with two ports should be installed similarly.
Step Five:
Fasten the bracket to the back panel of the computer with a screw. Replace the computer’s cover and replace
the screws. Now you can remove the wrist-strap.

9Chapter 3 Software Installation
CHAPTER 3 SOFTWARE INSTALLATION
The PC400 driver diskette contains the files needed to run the Cyclades-PC400 in a Linux environment. This
driver should run without problems with all processors supported by Linux. However, Ix86-compatible
architectures are the only platforms officially supported by Cyclades.
This Installation manual assumes a minimum knowledge of the Linux operating system. Please
read the file /usr/src/linux/README before continuing, in order to understand the basics of kernel
compilation.
System Requirements for compatibility with the PC400:
• Linux kernel 2.2.17 or later or 2.4.0 or later.
• 486 processor or better.
• PCI bus support.
These instructions assume that your kernel source tree is /usr/src/linux.
Before installing the driver, please back up any critical information in your system.
Log in to the Linux computer as root. Place the diskette in the diskette drive.
Execute the following commands, beginning from any directory:
cd /tmp
tar xvf /dev/fd0 (this command copies the tar file from the diskette to the directory /tmp)
ls (to see the name of the tar file)
tar zxvf filename.tgz (to unzip and untar the file)
ls (to see the name of the directory)
cd pc400-<version> (to go to the newly created directory)

10Chapter 3 Software Installation
NOTE: at this point you should read the file README included in the directory pc400-<version>
to learn about any changes implemented since this manual was produced.
sh install (to run the install script)
This script will detect the system information (kernel version, current Cyclades-PC400 driver version, etc.) and
install the proper driver package files. A default configuration file will be placed in /etc/cyclades/pc400/
pc400.cfg and is used when /usr/local/sbin/pc400util -p is executed.The following utilities are compiled and
installed :
/usr/local/sbin/pc400util
/usr/local/sbin/pc400load
/usr/local/sbin/pc400dump
/usr/local/sbin/pc400hwtest
/usr/local/sbin/pc400syslog
And the firmware is installed in
/usr/local/lib/pc400.bin
If an older version of the PC400 driver already exists, the files pc400.c and pc400.h are backed up with
modified names in the same directory. If a newer version is already installed, the files will not be updated with
those of the older driver.
Configure the kernel by executing “make config” or “make menuconfig”:
Please note the following before beginning the kernel configuration. The only difference between
selecting ‘Y’ , ‘∗’ or ‘M’ is the following: ‘Y’ or ‘∗’ causes the driver to be compiled as part of the
kernel and is activated every time the computer is booted; ‘M’ creates the driver as a module, which
can be loaded or unloaded with a command without the need to reboot the computer.
