Features and Benefits

Overview

The CCM console management appliance provides non-blocked access and control for devices such
as serial-managed Linux (or other UNIX) servers, routers, power management devices and firewalls.
This includes Avocent SPC power control devices that provide advanced power management.

• The CCM850 appliance has 8 serial ports. A single 10/100 Mbps Ethernet port provides net­work connectivity on each appliance. Two CCM850 appliances may be mounted in 1U of ver­tical space in a standard 19 inch rack.

• The CCM1650 appliance has 16 serial ports. A single 10/100 Mbps Ethernet port provides
network connectivity on each appliance. Two CCM1650 appliances may be mounted in 1U of
vertical space in a standard 19 inch rack.

• The CCM4850 appliance has 48 serial ports. A single 10/100/1000 Mbps Ethernet port
provides network connectivity on each CCM appliance. One CCM4850 appliance may be
mounted in 1U of vertical space in a standard 19 inch rack.

Each appliance has a console port that uses a Command Line Interface (CLI) for configuration,
management and optionally, connection to other ports.

1

Serial device access options

You may choose from among several client application options to access the CCM appliance and
its attached serial devices:

• The AVWorks
client and a Secure Shell (SSH) client

• Third party Telnet clients

• Third party SSH clients

Access to attached serial devices is also possible through the appliance serial CLI, plus PPP (Point
to Point Protocol) and other types of dial-in connections to a modem on the console port.

When session sharing is enabled, the CCM appliance supports multiple concurrent sessions.
Configured user access levels may be used as preemption criteria for serial port access.

®

cross-platform management application that offers a built-in enhanced Telnet

2 CCM Installer/User Guide

User authentication and data security

The CCM user database supports up to 64 user accounts, which include usernames, passwords and/
or keys, plus specifications of access rights/levels to CCM appliance ports and commands. User
definitions may be changed at any time. You may choose to have user access authenticated locally
at the CCM user database and/or at one or more RADIUS (Remote Access Dial-In User Service)
servers. Data security may be enhanced using industry-standard SSH encryption.

Extensive command set

The CCM appliance offers a wide range of commands that allow administrators to easily configure,
control and display information about the CCM appliance operating environment, including its
ports, user accounts and active sessions. The serial CLI is always available on the unit’s console
port, and may be easily accessed during a session with an attached serial device.

The user interface also offers descriptive error message data and built-in command help
information. On-board Trivial File Transfer Protocol (TFTP) support allows administrators to
upload new functionality to CCM appliances in the field.

Port history

Each CCM port has a buffer that holds the most recent 64K bytes of online and offline serial data.
A separate history command mode lets you navigate within a port’s current history file and conduct
tailored searches.

You may also configure the appliance to write serial port data to a file on an NFS server, thus
preventing data loss due to overflow of the history buffer.

Safety Precautions

To avoid potential device problems, if the building has 3-phase AC power, ensure that a computer
and its monitor (if used) are on the same phase. For best results, they should be on the same circuit.

To avoid potentially fatal shock hazard and possible damage to equipment, please observe the
following precautions:

• Do not use a 2-wire extension cord in any product configuration containing this appliance.

• Test AC outlets at the computer and monitor (if used) for proper polarity and grounding.

• Use only with grounded outlets at both the computer and monitor. When using a backup Unin­terruptible Power Supply (UPS), power the computer, the monitor and the CCM appliance off
the supply.

NOTE: The AC inlet is the main disconnect.

Rack mount safety considerations

• Elevated Ambient Temperature: If installed in a closed rack assembly, the operation tempera­ture of the rack environment may be greater than room ambient. Use care not to exceed the
rated maximum ambient temperature of the unit.

• Reduced Airflow: Installation of the equipment in a rack should be such that the amount of air­flow required for safe operation of the equipment is not compromised.

• Mechanical Loading: Mounting of the equipment in the rack should be such that a hazardous
condition is not achieved due to uneven mechanical loading.

• Circuit Overloading: Consideration should be given to the connection of the equipment to the
supply circuit and the effect that overloading of circuits might have on overcurrent protection
and supply wiring. Consider equipment nameplate ratings for maximum current.

• Reliable Earthing: Reliable earthing of rack mounted equipment should be maintained. Pay
particular attention to supply connections other than direct connections to the branch circuit
(for example, use of power strips).

Using AVWorks Software

The AVWorks cross-platform management application may be used to manage CCM appliances
and access attached devices. Using AVWorks software, you may perform most of the operations
that are described in this manual. This manual describes how to manage a CCM appliance by
entering commands using the CLI. The AVWorks Installer/User Guide describes how to manage a
CCM appliance using the graphic interface.

Installing the CCM Appliance

WARNING: This unit is not user serviceable. To avoid electrical shock, do not attempt to open the unit or operate

with the cover off. Do not attempt to make any repairs. See Appendix F on page 113 for information.

WARNING: The power outlet should be near the equipment and easily accessible.

To install the CCM appliance hardware:

1. Place the unit where you can connect cables between the serial devices and the CCM serial
ports, and where you can connect a LAN interface cable between the Ethernet hub or switch
and the CCM LAN connector.

2. Connect devices to the CCM serial ports; see Device Cabling on page 95 for cable information.
Connect each serial device to its appropriate power source, following the device’s documentation.

8 CCM Installer/User Guide

3. Attach a LAN interface cable to the LAN connector on the CCM appliance. A CAT 5 cable is
required for 100BaseT operation. For CCM4850 appliances, a CAT 6 cable is required for
1000BaseT operation.

4. Insert the power cord into the back of the CCM appliance. Insert the other end of the power
cord into a grounded electrical receptor.

5. Check that the POWER LED on the front of the unit is illuminated. If not, check the power
cable to ensure that it is inserted snugly into the back of the unit. The ONLINE LED will illu­minate within two to three minutes to indicate that the self-test is complete. If the ONLINE
LED blinks, contact Technical Support for assistance.

6. For CCM850/1650 appliances, check that the LINK LED is illuminated.

For CCM4850 appliances, check that the LAN port LEDs indicate that a 10, 100 or 1000 Mbps
link exists.

If there is no link, check the Ethernet cable to ensure that both ends are correctly inserted into
their jacks.

7. Once the POWER, ONLINE and appropriate LEDs are illuminated, proceed with the configu­ration process (if you will be using BootP, remove power from the appliance).

Configuring the CCM Appliance

To configure the CCM appliance, you must specify a unique IP address, plus other network address
information. This information will be stored in the CCM configuration database. During initial
login, you will specify a password for the Admin user.

Configuring the network address settings

You may configure the CCM appliance network address settings using AVWorks software, BootP
or the serial CLI on the console port.

To configure the network address settings using AVWorks software:

Using the AVWorks New Appliance Wizard is the easiest method to configure the CCM appliance
network address settings. See the AVWorks Installer/User Guide for instructions. After the
network address settings are configured, see Initial CCM appliance login on page 10.

To configure the network address settings using BootP:

1. Ensure that there is a BootP server on your network that is configured to correctly respond to a
BootP request from the CCM appliance. BootP servers require the Ethernet MAC address of
network devices. The Ethernet MAC address is printed on a label affixed to the appliance. See your
BootP server’s system administrator guide for information about configuring the BootP server.

2. After you have configured your network’s BootP server with the CCM appliance Ethernet
MAC address, IP address, subnet mask and gateway, restore power to the CCM appliance and
wait for the ONLINE LED to illuminate. Once this occurs, the CCM appliance has completed
the BootP protocol, obtained its network address information and stored these in FLASH.

Chapter 2: Installation and Configuration 9

3. You may verify that the BootP process was successful with a ping command, which tests net­work connectivity. The ping command is entered as:

ping <ip_address>

For example, the following command tests the network connectivity of a CCM appliance with
the IP address 192.168.0.5.

ping 192.168.0.5

4. If the CCM appliance completes the BootP successfully, you will see a display similar to
the following.

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 CCM appliance did not successfully obtain its IP address with the BootP protocol, you
will see a display similar to the following.

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 address information provided to the BootP server to confirm it is correct.
Verify that the Ethernet LAN adaptor cable is correctly installed on the CCM appliance and the
Ethernet hub.

After the network address settings are configured successfully, launch a Telnet session to the
assigned IP address. Then, see Initial CCM appliance login on page 10.

To configure the CCM appliance using the serial CLI:

1. Attach a compatible device to the console port. The compatible device types are: ASCII,
VT52, VT100, VT102, VT220 and VT320.

For cable and adaptor information, see Device Cabling on page 95. You may use any terminal
emulation program that is available on your system.

2. Configure your terminal or terminal emulation program as follows.

Baud rate 9600
Bits per character 8
Stop bits 1
Flow control None

3. Press the

Return or Enter key until a prompt appears, requesting your username. If you do not

receive a prompt after pressing the key five times, check your cable and serial settings to be
sure that they are correct.

4. Proceed to Initial CCM appliance login on page 10.

Rebooting and Reinitializing the CCM Appliance

You may reboot or reinitialize the CCM appliance by pressing a recessed button on the appliance
front panel or by issuing a command.

Rebooting

During a reboot, any active Telnet sessions, including your own, are terminated. Any configuration
changes that require a reboot will become effective when the reboot completes.

To reboot the appliance in hardware:

1. Locate the recessed RESET button on the front of the CCM appliance. An opened paper clip
may be used to depress the button.

2. Insert the opened paper clip in the recess, then depress the button.

To reboot the appliance with a command:

Issue a Server Reboot command.

Reinitializing

Reinitializing the CCM appliance removes configured information. This may be useful when
reinstalling the unit at another location in your network.You may erase the configuration database,
which contains all nonvolatile data except the IP address, subnet mask and gateway. You may also
erase both the configuration database and the network address information.

To reinitialize the CCM appliance in hardware:

1. Locate the recessed INIT button on the front of the CCM appliance. An opened paper clip may
be used to depress the button.

2. Insert the end of the opened paper clip in the recess, then depress and hold the button. The
ONLINE LED will blink, indicating an initialization has been requested. You have approxi­mately seven seconds to release the button before any action is taken.

After seven seconds, the ONLINE LED will blink more rapidly to confirm that the CCM
configuration database has been erased. Continuing to hold the INIT button for a few more seconds
will erase the IP address as well. The ONLINE LED will blink faster to confirm the deletion.

If any portion of FLASH is erased, the CCM appliance reboots when the INIT button is released.

Chapter 2: Installation and Configuration 11

To reinitialize the CCM appliance with a command:

1. Issue a Server Init command with the Config parameter if you wish to erase the configura­tion database but retain the network address information.

-or­Use the All parameter if you wish to erase the configuration database and the network
address information.

2. You are prompted to confirm or cancel the operation.

The appliance reboots after initializing the database and copying it to the configuration FLASH.

Operations

3

Overview

The CCM console management appliance and its ports are easily configured and managed to meet
your requirements for device connection, user authentication, access control, power status
monitoring, port history information display and Simple Network Management Protocol (SNMP)
compliance for use with third party network management products.

Configuring Global Settings

Generally, the CCM appliance-level commands affect console port operations, configure/initiate
physical operations and enable/disable features.

13

Console port settings

The Server CLI command includes parameters that configure the console port:

• The terminal type to be used

• Enabling/disabling connections to devices from the console port - see Connecting to devices
from the console port on page 18

• The modem initialization character - see Configuring and using dial-in connections on page 19

This command also covers the following:

• The CLI access character that will suspend a device session and place you in CLI command
mode (this value may be overridden at the port level) - see CLI Mode on page 26

• Local port history file processing options during connection and when a session ends - see
Managing Port History on page 33.

• The session time-out value, which indicates the period of inactivity that must occur before a
session is ended (this value may be overridden at the port level) - see Session time-out on
page 27

Network settings, updating firmware and rebooting/reinitializing the appliance

To change the CCM appliance IP, gateway or subnet addresses, use the Server Set command
(page 71).

14 CCM Installer/User Guide

To update the boot or application firmware on the appliance, use the Server FLASH command
(page 67).

The appliance may be rebooted or reinitialized by pressing a button on the appliance or by issuing a
command; see Rebooting and Reinitializing the CCM Appliance on page 10.

Updating the Appliance Clock

The CCM appliance supports the NTP protocol. When NTP is enabled, the real time clock on the
CCM appliance will be updated immediately after NTP is enabled, each time the appliance reboots
and optionally, at specified intervals.

You may specify one or two NTP servers to provide the time. An NTP server may be external or an
internal server that you supply. The primary server will be queried for the time first. If it does not
respond with a valid time, the secondary server will be queried.

To enable or disable NTP:

To enable NTP, issue an NTP command with the Enable parameter.

NTP ENABLE [IP=<prim_add>[,<sec_addr>]] [UPDATE=<hours>]

If this is the first time NTP is being enabled, you must specify at least one NTP server address.

If you want the time to be updated periodically, specify an update interval of up to 99 hours. If you
specify a zero interval value (which is the default), the time will be updated only when the CCM
appliance reboots.

When you enable NTP, you are prompted to confirm or cancel the operation.

To disable NTP, issue an NTP command with the Disable parameter.

NTP DISABLE

Configuring Serial Port Settings

You may configure a CCM port to support one of two types of target devices (TDs): SPC or console.

For more information about SPC power control devices, see the SPC Installer/User Guide.

A console TD may be a serial-managed Linux (or other Unix) server, router, firewall or other
supported serial device.

By default, CCM ports are configured with the settings listed in Table 3.2.

Table 3.2: Default Port Settings

Parameter Value

Target device Console

Name xx-xx-xx Pn (last 3 octets of MAC address plus the port number)

Baud rate 9600

Bits per character 8

Parity None

Stop bits 1

Flow control None

Chapter 3: Operations 15

Time-out 15 minutes

CLI access character Use Server CLI setting (^D)

Power None

Most of these settings are standard serial port operating characteristics.

The CLI access character parameter specifies how you access the CLI. For more information, see
CLI Mode on page 26.

The Power parameter instructs the CCM appliance to monitor the state of a specified RS-232
control signal. Signal transitions may be configured to trigger SNMP traps. The parameter value
indicates an inbound control signal (CTS, DCD or DSR) and the state of that signal (low or high).
When the defined signal is true, the CCM appliance interprets it as a power on condition for the
attached device; when the signal is false, a power off condition for the device is assumed. The
signal specified for flow control may not be used for power control, and vice versa.

Port groups

The CCM appliance supports access control groups which may include one or more serial ports.
This feature allows a user account to be granted access to a group of ports using a single
specification. Each port may belong to only one group (but multiple ports may belong to the same

16 CCM Installer/User Guide

group). One or more port groups may then be specified in a user account. A group name may
contain up to eight characters.

Up to 8 port groups may be specified for a CCM850 appliance user, up to 16 port groups for a
CCM1650 appliance user and up to 48 port groups for a CCM4850 appliance user.

For example, assume that ports 1, 2, 3 and 4 are assigned to a group named LINUX. Ports 5, 6, 7
and 8 are assigned to a group named ROUTERS.

Users who must be able to access all Linux devices can be granted this right by having the LINUX
group specified in each of their user accounts. Those users will be able to access the devices
connected to ports 1, 2, 3 and 4.

Users who must be able to access Linux and router devices can be granted this right by having both
the LINUX and the ROUTERS groups specified in their user accounts. Those users will be able to
access the devices connected to ports 1 through 8.

To configure TD=console serial port settings:

Issue a Port Set command. You may specify settings for one port, multiple ports or all ports.

PORT [<port>|ALL] SET TD=CONSOLE [NAME=<name>] [BAUD=<baud>]
[SIZE=<size>] [PARITY=<parity>] [STOP=<stop_bits>] [FLOW=<flow_ctrl>]
[TIMEOUT=<time-out>] [SOCKET=<socket>] [CHAR=^<cli_char>]
[TOGGLE=NONE|DTR] [POWER=<signal>] [GROUP=<group>]

For more information and descriptions of all valid parameters, see Port Set command on page 61.

To configure TD=SPC ports and settings:

Issue a Port Set command with the TD=SPC parameter.

PORT <port> SET TD=SPC [NAME=<name>] [GROUP=<group>]

When a port is configured for an SPC power control device, you may specify only the Name and
Group parameters; no other serial port settings may be specified with the Port Set command.
However, you may use the SPC command to change certain configuration values for the SPC device.

SPC <port>|ALL [MINLOAD=<amps>] [MAXLOAD=<amps>]

Use an SPC Socket command to configure or control the state of the sockets on the SPC device.

SPC <port>|ALL [SOCKET <socket>] [WAKE=ON|OFF] [ONMIN=<time>]
[OFFMIN=<time>] [POWER=ON|OFF|REBOOT]

For more information, see SPC Command on page 85 and SPC Socket Command on page 85.

NOTE: Users who wish to use the native command interfaces of the SPC device should specify TD=console.

To display serial port settings:

Issue a Show Port command.

SHOW PORT [<port>|ALL|NAMES|GROUPS]

When you request information about a port configured as TD=console, the display includes
configuration information, current power status (if power status monitoring has been enabled), plus
