Review this section to familiarize yourself with the CPS. It describes the front
and rear panels, connector pinouts and device cabling.
About the CPS
The INIT button (Figure 1) can be used to remove configured information
from a CPS unit. The CPS stores nonvolatile data, such as IP addresses and
usernames, in a database in FLASH. This information can be erased by
pressing the INIT button.
Note that pressing the INIT button will interrupt operation of the CPS and cause
re-initialization to occur.
CPS Hardware
INIT: Pushing this button will restore the CPS to
factory defaults.
RESET: Pushing this button will reboot the CPS.
The 100MBps LED lights when the CPS is connected to a
100 Mbps LAN.
The TRAFFIC LED blinks when there is network traffic.
The LINK LED is lit when the CPS recognizes that it has a
connection to the network.
The ONLINE LED is lit (not blinking) when the CPS’s
self-test and initialization procedures have completed
successfully.
The POWER LED is lit when the CPS is connected to a
power source.
Figure 1

14 CPS 810/1610 Installer/User Guide
The FLASH erase is performed in two phases. The first phase erases the
CPS Configuration Database, which contains all nonvolatile data EXCEPT the
IP address. The second phase erases the IP address and restores the CPS to
factory default settings. This feature can be used to erase a CPS’s FLASH for
reinstallation elsewhere on your network.
When the INIT button is first pressed, the ONLINE LED will begin to blink
to confirm that you have pressed the INIT button. Pressing the button and
holding it for 5 seconds erases the Configuration Database in the CPS FLASH.
When the database has been erased, the ONLINE LED begins to FLASH
rapidly. If you release the INIT button before the 5 second mark, no action is
taken and the CPS does not reinitialize. If the button is pressed and held for an
additional 5 seconds, the IP address is also erased.
If any portion of FLASH is erased, the CPS will reboot itself when the INIT
button is released.
The RESET button can be used to reset the CPS. Pushing this button will cause
an immediate reboot.
On the rear of the CPS, there are 8 (CPS810) or 16 (CPS1610) RJ-45 connectors
for serial cabling, a LAN connector for a 10baseT or a 100BaseT Interface cable
and a power receptacle.
Warning: The power outlet should be installed near the equipment and should
be easily accessible.
Figure 2: CPS Rear
Panel CPS1610 shown

A typical installation will provide serial cabling for up to 16 attached serial
devices. Locate the CPS so that you can connect cables between the serial
devices and the CPS serial ports. Refer to Appendix B: Device Cabling for
information on CPS serial port pinouts.
The CPS also requires connection to your network. Locate the CPS where
you can readily connect a LAN interface cable to the LAN connector on the
rear of the CPS.
1. Attach a 10BaseT or 100BaseT LAN interface cable to the LAN connector on
the back of the CPS. The CPS requires a CAT 5 cable for 100BaseT operation.
2. Insert the power cord into the rear of the CPS. Insert the other end of the
power cord into a grounded electrical receptacle.
3. Check that the PWR LED is illuminated. If not, check the power cable to
ensure that it is inserted snugly into the rear of the CPS.
The ONLINE LED will illuminate within one minute to indicate that the
CPS self-test is completed. If the ONLINE LED blinks, contact Avocent
Technical Support for assistance.
4. Check to see that the LINK LED is also illuminated. If not, check the
CAT 5 Ethernet cable to be sure that both ends are correctly inserted into
their jacks. If the CPS is not correctly connected to an Ethernet hub or
switch, it will not be possible to configure the CPS for operation. If the
CPS is connected to a 100MB Ethernet hub, then the 100Mbps LED will
also be illuminated.
Once the PWR, ONLINE, and LINK LEDs are illuminated, remove power from
the CPS and proceed to the next section, Configuring the CPS.
Warning: The CPS and all attached devices should be powered-down before servicing
the unit. Always disconnect the power cord from the wall outlet.
CPS Hardware Installation

16 CPS 810/1610 Installer/User Guide
To configure the CPS, you must enter the following information so that it can
be stored in the CPS database:
A unique IP address
The subnet mask for the network
A password for the “Admin” user
Serial port settings
There are several methods that you can use to configure your CPS. Review the
remainder of this section to determine which method best suits your configuration.
Configuring IP Address and Subnet Mask
There are four methods you can use to configure the IP address and subnet
mask for the CPS.
vConsole
BOOTP
TELNET Command Line Interface via RARP
Serial Command Line Interface via Port 1
These methods will work as documented on most Windows and UNIX systems.
However, the actual implementation of these features on your system may
differ from the instructions provided. In that case, refer to your system’s
administrator guide or use vConsole to simplify installation and configuration
of your CPS.
vConsole
The easiest method of configuring the CPS IP address and subnet mask is to
use the vConsole installation wizard. Refer to the enclosed vConsole CD-Rom
for detailed instructions on its use.
BOOTP
BOOTP is a standard internet protocol used by network devices to obtain their
IP address and subnet mask. To use BOOTP, there must be an existing BOOTP
server on your network, and you must configure the BOOTP server to correctly
respond to a BOOTP request from the CPS. Refer to your BOOTP server’s system
administrator handbook for information on configuring your BOOTP server.
Configuring the CPS

17
BOOTP servers require the Ethernet MAC address of network devices. The
Ethernet MAC address of the CPS is located on the rear panel of the CPS above
the LAN connector.
Once you have configured your network’s BOOTP server with the Ethernet
MAC address, IP address and subnet mask for the CPS, restore power to the
CPS and wait for the ONLINE LED to illuminate. Once the ONLINE LED is
illuminated, the CPS has completed BOOTP protocol, obtained its IP address
and subnet mask and stored these in FLASH.
You can verify that the BOOTP process was successful by using the ping
command. The ping command is often used to test network connectivity. The
format of the ping command is:
ping ip-address
To test network connectivity of your CPS, enter the ping command. This
example shows a ping command for a CPS with IP address 192.168.0.5. If the
CPS has completed BOOTP protocol successfully, you will see a display similar
to the following:
ping 192.168.0.5
Pinging 192.168.0.5 with 32 bytes of data:
Reply from 192.168.0.5: bytes=32 time<10ms TTL=128
Reply from 192.168.0.5: bytes=32 time<10ms TTL=128
Reply from 192.168.0.5: bytes=32 time<10ms TTL=128
Reply from 192.168.0.5: bytes=32 time<10ms TTL=128
If the CPS did not successfully obtain its IP address with BOOTP protocol, you
will see a display similar to the following:
ping 192.168.0.5
Pinging 192.168.0.5 with 32 bytes of data:
Request timed out.
Request timed out.
Request timed out.
Request timed out.
In this case, check the MAC address and IP address provided to the BOOTP
server and confirm that they are correct. Verify that the Ethernet LAN adaptor
cable is correctly installed on the CPS and the Ethernet hub.

an IP address

18 CPS 810/1610 Installer/User Guide
Once the IP address has been successfully configured, launch a TELNET client
to the IP address of the CPS to perform the initial CPS login. For additional
information, see Initial Login to the CPS in Chapter 2.
TELNET Command Line Interface
The CPS can also be configured directly from a TELNET Command Line
Interface (CLI). Choose a server or workstation that you will use to configure
the CPS. This server or workstation must have a TELNET client and must be
on the same LAN segment with the CPS to be configured.
First, you must update the server or workstation with the Ethernet MAC
address for the CPS and the IP address for the CPS. This is done by adding
a static entry to the ARP table via the arp command. When entering the arp
command, you must enter the Ethernet MAC address of the CPS and the IP
address to be assigned to the CPS. The Ethernet MAC address of the CPS is
located on the rear panel of the CPS above the LAN connector. The format
of the arp command is:
arp -s ip-address mac-address
For example, to assign IP address 192.168.0.5 to the CPS with Ethernet MAC
address 00-80-7D-54-01-54, enter the following command:
arp -s 192.168.0.5 00-80-7d-54-01-54
On a Unix platform, you may need to enter this command in the following
format:
arp -s 192.168.0.5 00:80:7d:54:01:54
To verify that the information is correctly entered, use the following arp com-
mand to display your entry:
arp -a
This command will show all of the arp entries for the server or workstation.
If you need additional help with the arp command, refer to your system’s
administrator guide for assistance.
Once the arp entry is correctly entered, launch your TELNET client to the IP
address assigned via the arp command.
During the first login, you must enter additional configuration information.
Refer to Chapter 2, Initial Login to the CPS for further instructions.
Example of the arp
command

19
Serial Command Line Interface
By factory default, Port 1 of the CPS is configured with a serial Command Line
Interface (CLI), which inhibits using Port 1 with an attached serial device.
Once configuration is completed you can disable the Serial CLI and use Port
1 with an attached serial device. For additional information, see Chapter 2,
Configuring Serial Port Settings. The serial CLI can be accessed by cabling
any ASCII TTY or VT100 compatible device to Port 1 of the CPS. Refer to
Appendix B: Device cabling, and attach an appropriate cable between the CPS
and your terminal.
You may also use any terminal emulation program available to you on your
system. To connect a standard DB-9 PC COM port to port 1 of the CPS, use the
following Avocent components:
Pn 690226 10 foot 8-wire Reversing Module Cable
Pn 210095 RJ-45 to DB-9 Female Adaptor
Configure your terminal or terminal emulation program settings as shown below:
Baud rate 9600 Baud
Bits per character 8
Parity None
Stop Bits 1
Flow Control None
Press the Return key until a prompt appears requesting your Username. If
you do not receive a prompt after pressing the Return key 5 times, check your
cable and serial settings to be sure that they are correct.
During the first login, you must enter additional configuration information.
Refer to Chapter 2, Initial Login to the CPS for further instructions.
Initial Login to the CPS
This section describes procedures for your first login to the CPS. All access to
the CPS, its serial ports and the attached devices, is protected by an authentica-
tion process. You must correctly enter a username and password to gain
access to the CPS. The CPS is shipped with a single user in its database.
Usernames and passwords are case sensitive, so when entering these values,
be sure to enter them exactly as shown. Upon establishing your TELNET or
serial CLI session you will be prompted for a username.

20 CPS 810/1610 Installer/User Guide
