Secure Racking

If Secure Racked units are installed in a closed or multi-unit rack assembly, they may require further evaluation by Certification Agencies. The following items must be considered.

1. The ambient within the rack may be greater than room ambient. Installation should be such that the amount of air flow required for safe operation is not compromised. The maximum temperature for the equipment in this environment is 55°C. Consideration should be given to the maximum rated ambient.

2. Installation should be such that a hazardous stability condition is not achieved due to uneven loading.

3. Side vents are used to dissipate heat generated within the unit. When mounting the unit in an equipment rack, make certain to allow adequate clearance for venting.

Input Supply

Check nameplate ratings to assure there is no overloading of supply circuits that could have an effect on overcurrent protection and supply wiring.

Warnings and Cautions:

Installation Instructions

Grounding

Reliable earthing of this equipment must be maintained. Particular attention should be given to supply connections when connecting to power strips, rather than direct connections to the branch circuit.

No Serviceable Parts Inside; Authorized Service Personnel Only

Do not attempt to repair or service this device yourself. Internal components must be serviced by authorized personnel only.

• Shock Hazard - Do Not Enter

• Lithium Battery CAUTION: Danger of explosion if battery is incorrectly replaced. Replace only with same or equivalent type recommended by the manufacturer. Discard used batteries according to the manufacturer's instructions.

Disconnect Power

If any of the following events are noted, immediately disconnect the unit from the outlet and contact qualified service personnel:

1. If the power cord becomes frayed or damaged.

2. If liquid has been spilled into the device or if the device has been exposed to rain or water.

Two Power Supply Cables

Note that some MPC series units feature two separate power circuits, and a separate power supply cable for each power circuit. If your MPC unit includes two power supply cables, make certain to disconnect both power supply cables from their power source before attempting to service or remove the unit.

Detached 15-Amp “Starter” Cable(s)

If the MPC unit includes a detached, 125 VAC, 15 Amp “Starter” Cable(s,) this allows you to connect the MPC to power for bench testing and initial start up is adequate for applications that only require 15 Amps. For 20-Amp power switching applications, please refer to the WTI Power Cable guide supplied with the unit, or use appropriate 20Amp cables.

Warnings and Cautions

Units with Attached Power Supply Cable(s)

For MPC units that include attached power supply cable(s), the socket outlet(s) shall be installed near the equipment and shall be accessible.

1. Introduction

WTI’s MPC series Managed Power Controllers allow secure, remote metering and management of AC powered rack mount equipment via SSL, SSH, SNMP, web browser, telnet, external modem or local terminal. The MPC can monitor power to your equipment, and automatically notify you when changes in current levels, temperature, circuit breaker status or other factors exceed user-defined threshold values.

The MPC features two separate power circuits with up to 20 Amps input feed handling capacity per branch circuit, and is available in a horizontal, rack mount version with eight or sixteen switched outlets, or as a “zero unit” vertical mount model with 20 switched outlets.

Power Metering and Management:

The MPC can constantly measure current consumption, temperature levels, ping response and other factors. If the MPC detects that user defined thresholds for these values have been exceeded, the unit can promptly notify you via email, SNMP, Syslog, LED or audible alarm. When temperature and current readings exceed user defined critical values, the MPC can also intelligently shed the current load by temporarily shutting down nonessential devices; when readings return to acceptable levels, the MPC can restore power to those devices to return to normal operating conditions.

In addition, the MPC can also notify you when the Invalid Access Lockout has been triggered, when one of the MPC circuit breakers is open, or when a loss of communication with the optional auxiliary units is detected. The MPC also records current consumption data to a convenient log file, which can be retrieved in ASCII, XML, or CSV format or displayed in graph format.

Security and Co-Location Features:

Secure Shell (SSHv2) encryption and address-specific IP security masks help to prevent unauthorized access to command and configuration functions.

The MPC also provides four different levels of security for user accounts: Administrator, SuperUser, User and ViewOnly. The Administrator level provides complete access to all plug functions, operating features and configuration menus. The SuperUser level allows switching and rebooting of all plugs but does not allow access to configuration functions. The User level allows access to only a select group of Administrator-defined plugs. The ViewOnly level allows you to check plug status and unit status, but does not allow switching or rebooting of outlets or access to configuration menus.

The MPC includes full Radius support, LDAP capability, TACACS capability, DHCP and an invalid access lockout feature. An Audit Log records all user access, login and logout times and command actions.

1-1

Convenient, Durable Design:

The MPC is available with an optional remote display panel, which can be used to show the status of MPC units installed in hard-to-reach spots, deep inside equipment racks. When additional outlets are needed, each MPC unit can also be connected to up to three Auxiliary/Remote MPC units, allowing control of up to 80 outlets via a single IP Address .

Model Numbers

The MPC series includes a variety of horizontal and vertical models to accommodate the power distribution needs of almost any rack mount application.

5. Basic Configuration

This section describes the basic configuration procedure for all MPC units. For more information on Reboot Options and Alarm Configuration, please refer to Section 6 and Section 7.

5.1. Communicating with the MPC Unit

In order to configure the MPC, you must first connect to the unit, and access command mode. Note that, the MPC offers two separate configuration interfaces; the Web Browser Interface and the Text Interface.

In addition, the MPC also offers three different methods for accessing command mode; via network, via modem, or via local console. The Web Browser interface is only available via network, and the Text Interface is available via network (SSH or Telnet), modem or local PC.

5.1.1. The Text Interface

The Text Interface consists of a series of simple ASCII text menus, which allow you to set options and define parameters by entering the number for the desired option using your keyboard, and then typing in the value for that option.

Since the Web Browser Interface and Telnet accessibility are both disabled in the default state, you will need to use the Text Interface to contact the unit via Local PC or SSH connection when setting up the unit for the first time. After you have accessed command mode using the Text Interface, you can then enable Web Access and Telnet Access, if desired, in order to allow future communication with the unit via Web Browser or Telnet. You will not be able to contact the unit via Web Browser or Telnet until you have specifically enabled those options.

Once Telnet Access is enabled, you will then be able to use the Text Interface to communicate with the MPC via local PC, Telnet or SSH connection. You can also use the Text Interface to access command mode via an external modem installed at the MPC's serial Console Port.

In order to use the Text Interface, your installation must include:

• Access via Network: The MPC must be connected to your TCP/IP Network, and your PC must include a communications program (such as HyperTerminal.)

• Access via Modem: An external modem must be installed at the MPC's RS-232 Console Port, a phone line must be connected to the external modem, and the Console Port must be configured for Modem Mode. In addition, your PC must include a communications program.

• Access via Local PC: Your PC must be physically connected to the MPC’s RS232 Console Port as described in Section 4, the MPC's Console Port must be configured for Normal Mode, and your PC must include a communications program.

5-1

Basic Configuration

To access command mode via the Text Interface, proceed as follows:

Note: When communicating with the unit for the first time, you will not be able to contact the unit via Telnet, until you have accessed command mode, via Local PC or SSH Client, and used the Network Parameters Menu to enable Telnet as described in Section 5.9.

1. Contact the MPC Unit:

a) Via Local PC: Start your communications program and press [Enter]. Wait

for the connect message, then proceed to Step 2.

b) Via Network: The MPC includes a default IP address (192.168.168.168) and a

default subnet mask (255.255.255.0.) This allows you to contact the unit from any network node on the same subnet, without first assigning an IP Address to the unit. For more information, please refer to Section 5.9.

i. Via SSH Client: Start your SSH client, and enter the MPC’s IP Address.

Invoke the connect command, wait for the connect message, then proceed to Step 2.

ii. Via Telnet: Start your Telnet Client, and then Telnet to the MPC’s IP

Address. Wait for the connect message, then proceed to Step 2.

c) Via Modem: Use your communications program to dial the number for the

external modem which you have connected to the MPC’s Console Port.

2. Login / Password Prompt: A message will be displayed, which prompts you to enter a username (login name) and password. The default username is "super" (all lower case, no quotes), and the default password is also "super".

3. If a valid username and password are entered, the MPC will display the Plug Status Screen, shown in Figure 5.1.

Basic Configuration

5.1.3. Access Via PDA

In addition to the Web Browser Interface and Text Interface, the MPC command mode can also be accessed by PDA devices. Note however, that due to nature of most PDAs, only a limited selection of MPC operating and status display functions are available to users who communicate with the unit via PDA.

When the MPC is operated via a PDA device, only the following functions are available:

• Plug Status Screen (Section 8.2)

• Plug Group Status Screen (Section 8.3)

• Plug Control Screen (Section 9.1.1)

• Plug Group Control Screen (Section 9.1.2)

• Current & Power Metering (Section 8.4)

• Current History Graph (Section 8.5)

• Unit Info (Shows Site I.D. message and firmware version.)

For more information on these functions, please refer to the appropriate section listed next to each function in the list above.

These screens will allow PDA users to review Plug Status and Plug Group Status, invoke switching and reboot commands, display Current Metering Readings, show Current History and display the Site I.D. and firmware version. Note however, that PDA users are not allowed to change or review MPC configuration parameters.

To configure the MPC for access via PDA, first consult your IT department for appropriate settings. Access the MPC command mode via the Text Interface or Web Browser interface as described in this section, then configure the MPC's Network Port accordingly, as described in Section 5.9.

In most cases, this configuration will be adequate to allow communication with most PDAs. Note however, that if you wish to use a BlackBerry® to contact the MPC, you must first make certain to configure the BlackBerry to support HTML tables, as described below:

1. Power on the BlackBerry, and then click on the BlackBerry Internet Browser Icon.

2. Press the Menu button, and then choose "Options."

3. From the Options menu, choose "Browser Configuration," then verify to make certain that "Support HTML Tables" is checked (enabled.)

4. Press the Menu button, and select "Save Options."

When you have finished communicating with the MPC via PDA, it is important to always close the session using the PDA's menu functions, rather than by simply closing the browser window, in order to ensure that the MPC has completely exited from command mode, and is not waiting for the inactivity timeout period to elapse. For example, to close a session on a BlackBerry, press the Menu button and then choose "Close."

5.2. Configuration Menus

Although the Web Browser Interface and Text Interface provide two separate means for selecting parameters, both interfaces allow access to the same set of basic parameters, and parameters selected via one interface will also be applied to the other. To access the configuration menus, proceed as follows:

• Text Interface: Refer to the Help Screen (/H) and then enter the appropriate command to access the desired menu. When the configuration menu appears, key in the number for the parameter you wish to define, and follow the instructions in the resulting submenu.

• Web Browser Interface: Click the appropriate link on the left hand side of the screen (see Figure 5.2) to access the desired configuration menu. To change parameters, click in the desired field and key in the new value or select a value from the pull-down menu. To apply newly selected parameters, click on the "Change Parameters" button at the bottom of the menu or the "Set" button next to the field.

The following sections describe options and parameters that can be accessed via each of the configuration menus. Please note that essentially the same set of parameters and options are available to both the Web Browser Interface and Text Interface.

Notes:

• Configuration menus are only available when you have logged into command

mode using a password that permits Administrator Level commands. SuperUser accounts are able to view configuration menus, but are not allowed to change parameters.

• Configuration menus are not available when you are communicating with the

MPC via PDA

• When defining parameters via the Text Interface, make certain to press the

[Esc] key to completely exit from the configuration menu and save newly defined parameters. When parameters are defined via the Text Interface, newly defined parameters will not be saved until the "Saving Configuration" message has been displayed and the cursor returns to the command prompt.

Basic Configuration

• Time Zone: Sets the time zone, relative to Greenwich Mean Time. Note that the Time Zone setting will function differently, depending upon whether or not the NTP feature is enabled and properly configured. (Default = GMT (No DST).)

◆

NTP Enabled: The Time Zone setting is used to adjust the Greenwich Mean

Time value (received from the NTP server) in order to determine the precise local time for the selected time zone.

◆

NTP Disabled: If NTP is disabled, or if the MPC is not able to access the NTP

server, then status screens and activity logs will list the selected Time Zone and current Real Time Clock value, but will not apply the correction factor to the displayed Real Time Clock value.

• NTP Enable: When enabled, the MPC will contact an NTP server (defined via the NTP Address prompts) once a day, and update its clock based on the NTP server time and selected Time Zone. (Default = Off.)

Notes:

• The MPC will also contact the NTP server and update the time whenever you

change NTP parameters.

• To cause MPC to immediately contact the NTP server at any time, make

certain that the NTP feature is enabled and configured, then type /F and press [Enter]. When the System Parameters menu appears, press [Esc]. The MPC will save parameters and then attempt to contact the server, as specified by currently defined NTP parameters.

• Primary NTP Address: Defines the IP address or domain name (up to 64 characters long) for the primary NTP server. (Default = undefined.)

Note: In order to use domain names for web addresses, DNS Server parameters must first be defined as described in Section 5.9.5.

• Secondary NTP Address: Defines the IP address or domain name (up to 64 characters long) for the secondary, fallback NTP Server. (Default = undefined.)

Note: In order to use domain names for web addresses, DNS Server parameters must be defined as described in Section 5.9.5.

• NTP Timeout: The amount of time in seconds, that will elapse between each attempt to contact the NTP server. When the initial attempt is unsuccessful, the MPC will retry the connection four times. If neither the primary nor secondary NTP server responds, the MPC will wait 24 hours before attempting to contact the NTP server again. (Default = 3 Seconds.)

5-10

Basic Configuration

5.3.2. The Invalid Access Lockout Feature

When properly configured and enabled, the Invalid Access Lockout feature will watch all login attempts made at the Network Port and serial Console Port. If the port exceeds the selected number of invalid attempts, then the port where the Invalid Attempts occurred will be automatically disabled for a user-defined length of time (Lockout Duration.) The Invalid Access Lockout feature uses two separate counters to track invalid access attempts:

• Serial Port Counter: Counts invalid access attempts at the RS232 Console Port. If the number of invalid attempts at the port exceeds the user-defined Lockout Attempts value, then the port will be locked.

• Telnet, SSH and Web Browser Counter: Counts all invalid attempts to access command mode via Telnet, SSH or Web Browser interface. If the number of cumulative invalid attempts exceeds the user-defined Lockout Attempts value, then the Network Port will be locked.

Note: In the Web Browser Interface, the Invalid Access Lockout item does not appear in the System Parameters Menu, and is instead accessed via the "Invalid Access Lockout" link on the left hand side of the screen.

Note that when an Invalid Access Lockout occurs, you can either wait for the Lockout Duration period to elapse (after which, the MPC will automatically reactivate the port), or you can issue the /UL command (type /UL and press [Enter]) via the Text Interface to instantly unlock all of the MPC's logical network ports.

Notes:

• When the Invalid Access Lockout Alarm has been enabled as described

in Section 7.7, the MPC can also provide notification via email, Syslog Message, and/or SNMP trap whenever an Invalid Access Lockout occurs.

• Invalid Access Lockout parameters, defined via the System Parameters

menu, will apply to both the Serial Console Port and the Network Port.

• When the Console Port is locked, an external modem connected to that port

will not answer.

• When either the Console Port or Network Port are locked, the other port will

remain unlocked, unless the Invalid Access Lockout feature has also been triggered at that port.

• If any one of the MPC’s logical network ports is locked, all other network

connections to the unit will also be locked.

• All invalid access attempts at the MPC Network Port are cumulative (the

count for invalid access attempts is determined by the total number of all invalid attempts at all 16 logical network ports.) If a valid login name/ password is entered at any of the logical network ports, then the count for all MPC logical network ports will be restarted.

• If the Network Port has been locked by the Invalid Access Lockout feature, it

will still respond to the ping command (providing that the ping command has not been disabled at the Network Port.)

5-11

Basic Configuration

The Invalid Access menus allow you to select the following:

• Lockout Enable: Enables/Disables the Invalid Access Lockout feature. (Default = On.)

• Lockout Attempts: The number of invalid attempts required in order to activate the Invalid Access Lockout feature. (Default = 9.)

• Lockout Duration: The length of time that logical network ports will remain locked when an Invalid Access Lockout occurs. If the duration is set at "Infinite", then ports will remained locked until the /UL command is issued. (Default = 30 Minutes.)

5-12

Basic Configuration

5.3.3. Automated Mode

The Automated Mode allows the MPC to execute switching and reboot commands, without displaying menus or generating response messages. Automated Mode is designed to allow the MPC to be controlled by a device which can generate commands to control power switching functions without human intervention.

When Automated Mode is enabled, power switching and reboot commands are executed without a “Sure?” confirmation prompt and without command response messages; the only reply to these commands is the “MPC>” prompt, which is re-displayed when each command is completed.

Note that although Automated Mode can be enabled using either the Web Browser Interface or Text Interface, Automated Mode is designed primarily for users who wish to send ASCII commands to the MPC without operator intervention, and therefore does not specifically apply to the Web Browser Interface. When Automated Mode is enabled, the Web Browser Interface can still be used to invoke switching and reboot commands.

Notes:

• When the Automated Mode is enabled, password prompts will not be

displayed at login, and you will be able to access Administrator Level command functions (including the configuration menus) and control plugs without entering a password.

• If you need to enable the Automated Mode, but want to restrict network

access to configuration menus, it is strongly recommended to enable and configure the IP Security Function as described in Section 5.9.3.

To enable/disable the Automated Mode, go to the System Parameters menu (see Section 5.3,) and then set the “Automated Mode” option to “On”. When Automated Mode is enabled, MPC functions will change as follows:

1. All Password Security Suppressed: When a user attempts to access command mode, the password prompt will not be displayed at either the Console Port or Network Port. Unless specifically restricted by the IP Security Function, all users will be allowed to access both switching and configuration functions, and all commands will be immediately accepted without the requirement to enter a password.

2. Status Screen Suppressed: The plug status screen will not be automatically displayed after commands are successfully executed. Note however, that the /S command can still be invoked to display the status screen as needed.

3. “Sure?” Prompt Suppressed: All commands are executed without prompting for user confirmation.

4. Error Messages Suppressed: Most error messages will be suppressed. Note however, that an error message will still be generated if commands are invoked using invalid formats or arguments.

All other status display and configuration commands will still function as normal.

5-13

Basic Configuration

5.3.4. Log Configuration

This feature allows you to create records of command activity, alarm actions and current and power consumption for the MPC unit. The Log features are enabled and configured via the System Parameters Menus. The ability to view the Current and Power Metering logs is individually enabled for each account via the User Directory as described in Section 5.5. The MPC features four event logs: the Audit Log, the Alarm Log, the Current Metering Log and the Power Metering Log:

• Audit Log: The Audit log creates a record of all power switching and reboot activity at the MPC unit, including reboots and switching caused by Load Shedding, Load Shedding Recovery, Ping No Answer Reboots and Scheduled Reboots. Each Log record includes a description of the activity that caused the power switching or reboot, the username for the account that initiated the power switching or reboot and the time and date that the power switching or reboot occurred.

• Alarm Log: The Alarm log creates a record of all Alarm Activity at the MPC unit. Each time an alarm is triggered, the MPC will generate a record that lists the time and date of the alarm, the name of the Alarm that was triggered, and a description of the Alarm.

• Current Metering Log: The Current Metering Log provides a record of current consumption for the MPC unit. Each Log record will include the time and date, current and voltage readings for each available branch circuit and the temperature reading. The Current Metering Log can be downloaded in ASCII, CSV or XML format, and when viewed via the Web Browser Interface, can also be displayed as a graph.

• Power Metering Log: The Power Metering Log provides a record of power consumption (in Kilowatt Hours) for the MPC unit. The Power Metering Log can be downloaded in ASCII, CSV or XML format, and when viewed via the Web Browser Interface, can also be displayed as a graph.

Note: If optional Auxiliary MPC units have been connected to the AUX ports on your local MPC unit, the Log Function will also record events that occur at the Auxiliary units too.

5-14

Basic Configuration

5.3.4.1. The Audit Log and Alarm Log

The System Parameters menu allows you to select three different configuration parameters for the Audit Log and Alarm Log. Note that the Audit Log and Alarm Log function independently, and parameters selected for one log will not be applied to the other.

• Off: The Log is disabled, and command activity and/or alarm events will not be logged.

• On - With Syslog: The Log is enabled, and power switching, reboot activity and/or alarm events will be logged. The MPC will generate a Syslog Message every time a Log record is created.

• On - Without Syslog: The Log is enabled, and power switching, reboot activity and/or alarm events will be logged, but the MPC will not generate a Syslog Message every time a Log record is created. (Default Setting.)

Notes:

• In order for the Audit Log or Alarm Log to generate Syslog Messages,

Syslog Parameters must first be defined as described in Section 5.9 and Section 11.1.

• The Audit Log will truncate usernames that are longer than 22 characters,

and display two dots (..) in place of the remaining characters.

5.3.4.2. The Current Metering Log and Power Metering Log

The System Parameters menu allows you to enable or disable Current Metering and Power Metering. When disabled, the MPC will not log current, power, voltage or temperature readings.

5.3.5. Callback Security

The Callback function provides an additional layer of security when callers attempt to access command mode via modem. When this function is properly configured, modem users will not be granted immediate access to command mode upon entering a valid password; instead, the unit will disconnect, and dial a user-defined number before allowing access via that number. If desired, users may also be required to re-enter the password after the MPC dials back.

In order for Callback Security to function properly, you must first enable and configure the feature via the System Parameters menu as described in this section, and then define a callback number for each desired user account as described in Section 5.5. To configure and enable the Callback function, proceed as follows:

• Text Interface: Type /F and press [Enter] to access the System Parameters menu, then type 6 and press [Enter] to display the Callback Security Menu.

• Web Browser Interface: Click the "System Properties" link on the left hand side of the screen to access the System Configuration menu, then click the "Configure Callback Security" link to display the Callback Security Menu.

In both the Text Interface and Web Browser Interface, the Callback Security Menu offers the following options:

• Callback Enable: This prompt offers five different configuration options for the Callback Security feature: (Default = On - Callback (Without Password Prompt.)

◆

Off: All Callback Security is disabled.

◆

On - Callback (Without Password Prompt): Callbacks will be performed for

user accounts that include a Callback Number, and the login prompt will not be displayed when the user’s modem answers. If the account does not include a Callback Number, that user will be granted immediate access and a Callback will not be performed.

◆

On - Callback (With Password Prompt): Callbacks will be performed for user

accounts that include a Callback Number, and the login prompt will be displayed when the user’s modem answers (accounts that include a Callback Number will be required to re-enter their username/password when their modem answers.) If the account does not include a Callback Number, then that user will be granted immediate access and a Callback will not be performed.

◆

On - Callback ONLY (Without Password Prompt): Callbacks will be performed

for user accounts that include a Callback Number, and the username/password prompt will not be displayed when the user’s modem answers. Accounts that do not include a Callback Number will not be able to access command mode via modem.

◆

On - Callback ONLY (With Password Prompt): Callbacks will be performed

for user accounts that include a Callback Number, and the username/password prompt will be displayed when the user’s modem answers (users will be required to re-enter their username/password when their modem answers.) Accounts that do not include a Callback Number will not be able to access command mode via modem.

5-17

Basic Configuration

• Callback Attempts: The number of times that the MPC will attempt to contact the Callback number. (Default = 3 attempts.)

• Callback Delay: The amount of time that the MPC will wait between Callback attempts. (Default = 30 seconds.)

Notes:

• After configuring and enabling Callback Security, you must then define a

callback phone number for each desired user account (as described in Section 5.5) in order for this feature to function properly.

• When using the "On - Callback (With Password Prompt)" option, it is

important to remember that accounts that do not include a callback number will be allowed to access command mode without callback verification.

5-18

Basic Configuration

5.4. User Accounts

Each time you attempt to access command mode, you will be prompted to enter a username (login) and password. The username and password entered at login determine which plug(s) you will be allowed to control and what type of commands you will be allowed to invoke. Each username / password combination is defined within a "user account."

The MPC allows up to 128 user accounts; each account includes a username, password, security level, plug access rights, service access rights and an optional callback number.

5.4.1. Command Access Levels

In order to restrict access to important command functions, the MPC allows you to set the command access level for each user account. The MPC offers four different access levels: Administrator, SuperUser, User and View Only. The command privileges for each user account are set using the "Access Level" parameter in the Add User or Modify User menus.

Each access level grants permission to use a different selection of commands; lower access levels are restricted from invoking configuration commands, while Administrators are granted access to all commands. The four different access levels can be summarized as follows:

• Administrator: Administrators are allowed to invoke all configuration and operation commands, can view all status screens, and can always direct switching and reboot commands to all of the MPC's switched outlets .

• SuperUser: SuperUsers are allowed to invoke all power switching and reboot commands and view all status screens. SuperUsers can view configuration menus, but are not allowed to change configuration parameters. SuperUsers are granted access to all MPC outlets.

• User: Users are allowed to invoke power switching and reboot commands and view all status screens, but can only apply commands to the outlets that they are specifically granted access to. In addition, Users are not allowed to view configuration menus or change configuration parameters.

• ViewOnly: Accounts with ViewOnly access, are allowed to view Status Menus, but are not allowed to invoke reboot and switching commands, and cannot view configurations menus or change configuration parameters. ViewOnly accounts can display the Plug Status screen, but can only view the status of plugs that are specifically allowed by the account.

Section 17.2 summarizes command access for all four access levels.

5-19

Basic Configuration

In the default state, the MPC includes one predefined account that provides access to Administrator commands and allows control of all of the MPC's switched power outlets. The default username for this account is "super" (lowercase, no quotation marks), and the password for the account is also "super".

Notes:

• In order to ensure security, it is recommended that when initially setting up

the unit, a new user account with Administrator access should be created, and the "super" account should then be deleted.

• If the MPC is reset to default parameters, all user accounts will be cleared,

and the default "super" account will be restored.

5.4.2. Plug Access

Each account can be granted access to a different selection of switched power outlets (plugs) and plug groups. When accounts are created, the Plug Access parameter and the Plug Group Access parameter in the Add User menu or Modify User menu can be used to grant or deny access to each plug or plug group by that account.

In addition, each command access level also restricts the plugs and plug groups that the account will be allowed to access:

• Administrator: Accounts with Administrator access are always allowed to control all plugs and plug groups. Plug access cannot be disabled for Administrator level accounts.

• SuperUser: SuperUser accounts allow access to all plugs and plug groups. Port access cannot be disabled for SuperUser accounts.

• User: Accounts with User level access are only allowed to issue switching and reboot commands to the plugs and plug groups that have been specifically permitted via the "Plug Access" parameter in the Add User and Modify User menus.

• ViewOnly: Accounts with ViewOnly access are not allowed to issue switching and reboot commands to outlets or plug groups. ViewOnly accounts can display the On/Off state of plugs and plug groups, but are limited to the plugs and plug groups specified by the account.

5-20

Basic Configuration

5.4.3. Port Access

The Port Access parameter can be used to grant connection access to the MPC's DB-9 Console port, RJ-45 Remote port and RJ-45 AUX ports. Normally, the Console port is used for connection to a local control device such as a laptop, the Remote port is used for connection to the optional MPC-DISPLAY unit, and the AUX ports are used for connection to additional remote MPC units. However, if your application requires communication with other devices in the equipment rack the Console port, Remote port and AUX ports can also be used for connection to these devices.

Administrator and SuperUser level accounts are always allowed access to the Console Port, and User level accounts can always be granted access to the Console port. Note however, that in order to allow an account to access the AUX ports and Remote port, these ports must first be reconfigured as serial ports as described in Section 5.8.2. When the AUX ports and Remote port are left in their default configuration, accounts will not be allowed to create connections to these ports.

In addition, the command access level will also determine which ports the account will be allowed to access, as summarized below:

• Administrator and SuperUser: Accounts with Administrator or SuperUser level command access are always allowed to connect to the Console Port. If the AUX and Remote ports are configured as serial ports, then Administrator and SuperUser level accounts will also be allowed to connect to these ports. Port access cannot be disabled for Administrator and SuperUser level accounts.

• User: User level accounts are only allowed to connect to the Console Port when port access has been specifically enabled for the account. If the AUX and Remote ports are configured as serial ports, then User level accounts can also be granted access to these ports.

• ViewOnly: Accounts with ViewOnly access are not allowed to create connections to the serial ports.

5-21

Basic Configuration

5.5. Managing User Accounts

The User Directory function is employed to create new accounts, display parameters for existing accounts, modify accounts and delete accounts. Up to 128 different user accounts can be created. The "User Directory" function is only available when you have logged into command mode using an account that permits Administrator commands.

• Text Interface: Type /F and press [Enter] to access the System Parameters Menu. From the System Parameters Menu, type 1 and press [Enter] to access the User Directory.

5.6. The Plug Group Directory

The Plug Group Directory allows you to designate "groups" of plugs that are dedicated to a similar function, and will most likely be switched or rebooted all at the same time or controlled by the same type of user account.

For example, an individual equipment rack might include an assortment of devices that belong to different departments or clients. In order to simplify the process of granting plug access rights to the accounts that will control power to these devices, you could assign all of the plugs for the devices belonging to Department A to a Plug Group named "Dept_A", and all of the plugs for the devices belonging to Department B to a Plug Group named "Dept_B". When user accounts are defined later, this would allow you to quickly grant access rights for all of the plugs for the devices belonging to Department A to the appropriate user accounts for Department A, by merely granting access to the Dept_A Plug Group, rather than by selecting the specific, individual plugs for each Department A user account.

Likewise, Plug Groups allow you to direct On/Off/Boot commands to a series of plugs, without addressing each plug individually. Given the example above, you could quickly reboot all plugs for Department A, by either including the "Dept_A" Plug Group name in a /BOOT command line via the Text Interface, or by using the Plug Group Control menu via the Web Browser Interface.

5.7. Defining Plug Parameters

The Plug Parameters Menu is used to define Plug Names, boot/sequence delay times and Power Up Default values for each of the MPC's Switched AC Outlets. Note that this function is only available when you have accessed command mode using a password that permits Administrator Level commands. To define Plug Parameters, proceed as follows:

• Text Interface: Type /PL and then press [Enter]. The Plug Parameters Menu will be displayed as shown in Figure 5.9. To define Plug Parameters, key in the number for the desired parameter, press [Enter] and then follow the instructions in the resulting submenu.

• Web Browser Interface: Click the "Plug Parameters" link on the left hand side of the screen to display the Plug Group Directory menu (Figure 5.10.) To define Plug Parameters, either place the cursor in the Plug Name field and key in a new name, or locate the drop down menu for the desired parameter, click on the down arrow, and scroll to the desired parameter and select it. When you are finished selecting Plug Parameters, click the "Change Plugs" button to apply he new parameters.

The Plug Parameters Menu allows you to define the following parameters:

• Plug Name: (Up to 16 Characters, Default = undefined.)

Note: Plug Names must begin with either a lower case alphabetic letter or upper case alphabetic letter. Plug Names cannot begin with a number character or symbol character.

• Boot/Seq. Delay: When more than one plug is switched On or a reboot cycle is initiated, the Boot/Sequence delay determines how much time will elapse before the next plug is switched On. When the Boot/Sequence Delay is applied, the MPC will wait for the user-defined delay period before switching On the next plug. This allows time for the device connected to the first plug to adequately "wake up" before switching on power to the device connected to the next plug. When Reboot cycles and switching actions are initiated, the Boot/Sequence Delay will be applied as follows: (Default = 0.5 Second.)

■

Reboot Cycle Delay: During a reboot cycle, the MPC will first switch all selected

plugs "Off" (with a 0.5 second pause between each "Off" operation), and then begin to switch selected plugs back On again, pausing for the user-defined Boot/Sequence Delay before switching On the next plug. For example, if the Boot/Sequence Delay for Plug 3 is ten seconds, then the MPC will pause for ten seconds before proceeding to the next plug.

■

"On" Sequence Delay: When two or more plugs are switched On, the MPC will

pause for the user-defined Boot/Sequence Delay before switching On the next plug.

5-36

Basic Configuration

• Power Up Default: Determines how this plug will react when the Default command (/D) is invoked, or after power to the unit has been interrupted and then restored. After the default command is invoked, or power is restored, the MPC will automatically switch each plug On or Off as specified by the Power-Up Default. (Default = On).

Note:

• If you have accessed command mode using an account that permits

Administrator or SuperUser level commands, then the Default command will be applied to all switched plugs.

• If you have accessed command mode using an User Level account, then the

Default command will only be applied to plugs allowed by your account.

• Boot Priority: When commands are applied to two or more plugs, the Boot Priority parameter determines the order in which the plugs will be switched On. The Plug that has been assigned a Boot Priority of "1" will always be switched on first, followed by the plug that has been assigned the Boot Priority of "2", and so forth. When you assign a boot priority to any given plug, then all subsequent plugs will have their priority lowered by one. For more information on the Boot Priority parameter, please refer to Section 5.7.1. (Default = All plugs prioritized according to Plug Number.)

5.7.1. The Boot Priority Parameter

Normally, when an "On" or "Reboot" command is invoked, the MPC will switch on it's plugs in their default, numeric order. Although in many cases, the default, numeric order will work fine, there are other cases where an individual device (such as a router) must be switched on first, in order to support a second device that will be switched on later.

The Boot Priority Parameter simplifies the process of setting the order in which plugs are switched On, by assigning a priority number to each plug, rather than by requiring the user to make certain that devices are always connected to the MPC in a set order. Likewise, when new devices are added to your equipment rack, the Boot Priority Parameter eliminates the need to unplug all existing devices and then rearrange the plugs connected to the MPC (and re-define plug parameters) to ensure that they are switched on in the desired order.

Notes:

• No two plugs can be assigned the same Boot Priority number.

• When a higher Boot Priority is assigned to any given plug, all subsequent

plugs will have their boot priorities lowered by a factor of 1.

• The Boot Priority is also displayed on the Plug Status Screen.

5.7.1.1. Example 1: Change Plug A3 to Priority 1

In the Example shown in Figure 5.11, we start out with all Plugs set to their default Boot Priorities, with Plug A1 first, Plug A2 second and so forth.

Next, the Boot Priority for Plug A3 is changed to Priority 1. This means that Plug A3 will now be switched On first after a reboot, and that Plug A1 will now be switched On second, Plug A2 will be third, etc..

Note that when the Boot Priority for Plug A3 is set to 1, the Boot Priorities for all plugs that were previously Booted before plug A1 are now lowered by a factor of one

5.7.1.2. Example 2: Change Plug A5 to Priority 2

Next, the Boot Priority for Plug A5 is changed to Priority 2. This means that Plug A3 will continue to be switched on first after a reboot, but now Plug A5 will be switched on second, Plug A3 will be third, Plug A2 will be fourth, Plug A4 will be fifth and Plug A6 will still be sixth.

Once again, note that when the Boot Priority for Plug A5 is set to 2, the Boot Priorities for all plugs that were previously Booted before plug A5 are now lowered by a factor of one

5.8. Serial Port Configuration

The Serial Port Configuration menus allow you to select parameters for the MPC's serial Console Port, as well as the Remote Port and AUX Ports.

• Console Port: The serial Console Port (Port 1) can be configured for connection to a local PC or Modem or used for connection to serial console ports on other rack equipment. In addition, the Serial Port Configuration menu can also be used to set communications parameters, disable Administrator level commands at the Console Port and also select a number of other Console Port Parameters described in Section 5.8.1.

• Remote Port: The RJ45 Remote Port is normally used for connection to the optional MPC-DISPLAY remote display panel. Note however, that if necessary, the Serial Port Configuration menu can also be used to configure the Remote Port for communication with other serial devices as described in Section 5.8.2.

• AUX Ports: The RJ45 AUX Ports are normally used for connection to optional remote MPC units. This allows you to connect up to three additional MPC units when you need to control additional power outlets via a single IP address. If necessary, the Serial Port Configuration menus can also be used to configure the AUX ports for communications with other serial devices as described in Section 5.8.2.

5.8.1. Console Port Configuration

To configure the MPC's serial Console Port, proceed as follows:

• Text Interface: Type /P 1 and then press [Enter]. The Port Parameters menu will be displayed as shown in Figure 5.13.

• Web Browser Interface: Click the "Serial Port" link on the left hand side of the screen to display the Serial Port Configuration Menu. From the Serial Port Configuration menu, use the dropdown menu to select Port 1 (the Console Port) and then click on the Select Port button to display the Serial Port 1 Configuration Menu, as shown in Figure 5.14.

The Console Port Configuration menu allows the following parameters to be defined. Note that all of these parameters are available via both the Text Interface and Web Browser Interface, and that parameters selected via one interface are also applied to the other.

Communication Settings:

• Baud Rate: Any standard rate from 300 bps to 115.2K bps. (Default = 9600 bps)

• Bits/Parity: (Default = 8-None).

• Stop Bits: (Default = 1).

• Handshake Mode: XON/XOFF, RTS/CTS (hardware), Both, or None. (Default = RTS/CTS).

5-41

Basic Configuration

General Parameters:

• Administrator Mode: Permits/denies port access to Administrator and SuperUser level accounts. When enabled (Permit), the port will be allowed to invoke Administrator and SuperUser level commands, providing they are issued by an account that permits them. If disabled (Deny), then accounts that permit Administrator and SuperUser level commands will not be allowed to access command mode via this port. (Default = Permit).

• Logoff Character: The Logoff Character determines the command(s) or character(s) that must be issued at this port in order to disconnect. Note that the Logoff Character does not apply to Direct Connections. (Default = ^X.)

• Sequence Disconnect: Enables/Disables and configures the disconnect command. This item offers the option to disable the Sequence Disconnect, select a one character format or a three character format. (Default = One Character.)

• Inactivity Timeout: Enables and selects the Timeout Period for this port. If enabled, the Console Port will disconnect when no additional data activity is detected for the duration of the timeout period. (Default = 5 Minutes.)

• Command Echo: Enables or Disables command echo at the Console Port. When disabled, commands that are sent to the Console Port will still be invoked, but the actual keystrokes will not be displayed on your monitor. (Default = On.)

• Accept Break: Determines whether the port will accept breaks received from the attached device. When enabled, breaks received at the port will be passed to any port that this port is connected to. When disabled, breaks will be refused at this port. (Default = On.)

5-42

Basic Configuration

Port Mode Parameters:

• Port Name: Allows you to assign a name to the Console Port. (Default = undefined.)

• Port Mode: The operation mode for this port. (Default = Normal Mode)

Depending on the Port Mode selected, the MPC will also display the additional

prompts listed below. In the Text Interface, these parameters are accessible via a submenu, which will only be active when the appropriate port mode is selected. In the Web Browser Interface, fields will be "grayed out" unless the corresponding port mode is selected.

◆

Normal Mode: Allows communication with a local PC and permits access to

command mode. When the Normal Mode is selected, the following modespecific parameter can also be defined:

➤ DTR Output: Determines how DTR will react when the port disconnects. DTR

can be held low, held high, or pulsed for 0.5 seconds and then held high. (Default = Pulse.)

◆

Modem Mode: Permits access to command mode and simplifies connection

to an external modem. Modem Mode ports can perform all functions normally available in Normal Mode, but Modem Mode also allows definition of the following, additional parameters:

➤ Reset String: Redefines the modem reset string. The Reset String can be

sent prior to the Initialization string. (Default = ATZ.)

➤ Initialization String: Defines a command string that can be sent to

initialize a modem to settings required by your application. (Default = AT&C1&D2S0=1&B1&H1&R2)

➤ Hang-Up String: Although the MPC will pulse the DTR line to hang-up an

attached modem, the Hang-Up string is often useful for controlling modems that do not use the DTR line. (Default = undefined.)

➤ Periodic Reset Value: Determines how often the Reset String will be sent to

the modem at this port.

Note: When communicating with the MPC via modem, these parameters will not be changed until after you exit command mode and disconnect.

5.8.2. Remote Port and AUX Port Configuration

In most applications, it is not necessary to change the configuration of the Remote Port or AUX Port. If you do not intend to use the Remote or AUX ports, or if you intend to use the Remote Port and AUX Ports for connection to the optional MPC-DISPLAY unit and additional MPC units, then the factory default settings for these ports will work fine and you will not need to change the configuration of these ports.

Note however, that in addition to their default functions (connection to the MPC-DISPLAY unit or additional MPC units), the Remote and AUX Ports can also be configured to allow serial communication with Console Ports on attached devices. In this case, you must reconfigure the MPC's Remote and/or AUX Ports as follows:

• Text Interface: Type /P AUX and then press [Enter]. The Remote/AUX Port Parameters menu will be displayed as shown in Figure 5.15.

• Web Browser Interface: Click the "Serial Port" link on the left hand side of the screen. From the Serial Port Configuration menu, use the dropdown menu to select "Aux" and then click on the Select Port button to display the Remote/AUX Port Configuration Menu, as shown in Figure 5.16.

The Remote/AUX Port Configuration menus allow the following parameters to be defined. Note that all of these parameters are available via both the Text Interface and Web Browser Interface, and that parameters selected via one interface are also applied to the other.

• Port Function: Determines whether each port will be used for connection to optional MPC devices, or used for serial communication. (Default: Remote Port = "Remote"; AUX Port = "AUX".)

Notes:

• In the default state all other Remote/AUX Port parameters are inaccessible.

When the Remote/AUX Mode is selected for a port, additional menu items for that port will then be activated.

• When the Remote and/or AUX Ports are used for serial communication,

Alarms will be temporarily suppressed whenever the ports are connected.

• If the AUX port is already connected to an AUX MPC unit, then you will need

to re-initialize the AUX unit before configuring the AUX port as a serial port. Access your local MPC unit via the Text Interface and then issue the /I (initialize) command at your local MPC unit. When the submenu appears, select the AUX port that you intend to reconfigure as a serial port. After the command is completed, disconnect the AUX MPC unit from the AUX port and then reconfigure the AUX port as described in this section.

• When an AUX or Remote port is set for Serial Port mode, then accounts

that permit access to that port will be allowed to invoke the /C command to connect to the port as described in Section 9.2.4.

Basic Configuration

5.9. Network Configuration

The Network Parameters Menus are used to select parameters and options for the Network Port and also allow you to implement IP Security features, which can restrict access based on the user’s IP Address.

Although the Web Browser Interface and Text Interface allow definition of essentially the same parameters, parameters are arranged differently in the two interfaces. In the Text Interface, most network parameters are defined via one menu. But in the Web Browser Interface, network parameters are divided into separate menus as described in this section.

To access the Network Parameters Menus, proceed as follows:

• Text Interface: Type /N and press [Enter]. The Network Parameters Menu shown in Figure 5.17 will be displayed.

• Web Browser Interface: Click on the "Network Configuration" link on the left hand side of the screen. The MPC will display the Network Configuration menu shown in Figure 5.18, which allows you to access the various submenus used to configure the network port.

Notes:

• Settings for network parameters depend on the configuration of your network.

Please contact your network administrator for appropriate settings.

• The Network Parameters Menu selects parameters for all 16 logical Network

Ports.

• When a new IP Address is selected, or the status of the DHCP feature is

changed, the unit will disconnect and reconfigure itself with the new values when you exit the Network Parameters Menu. When configuring the unit via Web or Telnet, make certain your DHCP server is set up to assign a known, fixed IP address in order to simplify reconnection to the unit after the new address has been assigned.

• The Network Parameters menu is only available when you have logged into

command mode using an account and port that permit Administrator level commands (Supervisor Mode enabled.)

The Network Parameters menu allows you to define the parameters discussed in the following sections. Note that although the descriptions of network parameters are arranged according to the Web Browser Interface, in the Text Interface, most parameters are included in a single menu.

5-48

Basic Configuration

5.9.1. Network Port Parameters

In the Text Interface, these parameters are found in the main Network Configuration menu (Figure 5.17.) In the Web Browser Interface, these parameters are found by clicking the "Network Port Parameters" link on the left hand side of the screen to display the Network Port Configuration Menu.

• Administrator Mode: Permits/denies port access to accounts that allow Administrator or SuperUser level commands. When enabled (Permit), the port will be allowed to invoke Administrator and SuperUser level commands, providing they are issued by an account that permits them. If disabled (Deny), then accounts that permit Administrator and SuperUser level commands will not be allowed to access command mode via this port. (Default = Permit)

• Logoff Character: Defines the Logoff Character for this port. This determines which command(s) must be issued at this port in order to disconnect from a second port. (Default = ^X ([Ctrl] plus [X]).)

Note: The Sequence Disconnect parameter can be used to pick a one character or a three character logoff sequence.

• Sequence Disconnect: Enables/Disables and configures the Resident Disconnect command. Offers the option to either disable the Sequence Disconnect, or select a one character, or three character command format. (Default = One Character).

Notes:

• The One Character Disconnect is intended for situations where the

destination port should not receive the disconnect command. When the Three Character format is selected, the disconnect sequence will pass through to the destination port prior to breaking the connection.

• When Three Character format is selected, the Resident Disconnect uses the

format "[Enter]LLL[Enter]", where L is the selected Logoff Character.

• Inactivity Timeout: Enables and selects the Inactivity Timeout period for the Network Port. If enabled, and the port does not receive or transmit data for the specified time period, the port will disconnect. (Default = 5 Minutes).

• Command Echo: Enables or Disables the command echo for the Network Port. (Default = On).

• Accept Break: Determines whether the port will accept breaks received from the attached device, and pass them along to a connected port. When enabled, breaks received at this port will be passed to any port this port is connected to, and sent to the device connected to the other port. When disabled, breaks will be refused at this port. (Default = On.)

• Multiple Logins: If the MPC is installed in an environment that does not include communication via an open network (local communication only), then the Multiple Logins parameter can be used to determine whether or not multiple users will be able to communicate with the unit at the same time. If this parameter is set to "Off" then only one user will be allowed to communicate with the unit at a time. (Default = On.)

Note: The "Multiple Logins" prompt is not included in the Web Browser Interface.

5-49

Basic Configuration

5.9.2. Network Parameters

In the Text Interface, these parameters are accessed via the Network Configuration menu (Figure 5.17.) In the Web Browser Interface, these parameters can be found by clicking the "Network Parameters" link on the left hand side of the screen to display the Network Parameters menu.

• IP Address: (Default = 192.168.168.168.)

• Subnet Mask: (Default = 255.255.255.0.)

• Gateway Address: (Default = undefined.)

• DHCP: Enables/Disables Dynamic Host Configuration Protocol. When this option is "On", the MPC will perform a DHCP request. Note that in the Text Interface, the MAC address for the MPC is listed on the Network Status Screen. (Default = Off.)

Note: Before configuring this feature via Telnet or Web, make certain your DHCP server is set up to assign a known, fixed IP address. You will need this new IP address in order to reestablish a network connection with the MPC unit.

• Telnet Access: Enables/disables Telnet access. When Telnet Access is "Off," users will not be allowed to establish a Telnet connection to the unit. (Default = On.)

• Telnet Port: Selects the TCP/IP port number that will be used for Telnet connections. Note that in the Text Interface, this item is defined via a submenu, which is displayed when the Telnet Access parameter is selected (item number 21.) (Default = 23.)

• SSH Access: Enables/disables SSH communication. (Default = On.)

• SSH Port: Selects the TCP/IP port number that will be used for SSH connections. Note that in the Text Interface, this option is defined via a submenu that is displayed when the SSH Access parameter is selected (item number 22). (Default = 22.)

• HTTP Access (Web Access): Enables/disables the Web Browser Interface. When disabled, users will not be allowed to contact the unit via the Web Browser Interface. (Default = Off.)

• HTTP Port: Selects the TCP/IP port number that will be used for SSH connections. (Default = 80.)

• HTTPS Access: Enables/disables HTTPS communication. For instructions on setting up SSL encryption, please refer to Section 14. (Default = On.)

• HTTPS Port: Selects the TCP/IP port number that will be used for HTTPS connections. (Default = 443.)

Notes:

• In the Text Interface, HTTP and HTTPS parameters reside in a separate

submenu. To enable and configure HTTP and HTTPS Access via the Text Interface, access the Network Configuration Menu as described in Section 5.9, then type 23, press [Enter] and use the resulting submenu (Figure 14.1) to select parameters.

• When the Web Access parameter is accessed via the Text Interface, the

resulting submenu will also allow you to select SSL (encryption) parameters as described in Section 14.

5-50

Basic Configuration

• SYSLOG Address: The IP Address or domain name (up to 64 characters) for the Syslog Daemon that will receive log records generated by the MPC. For more information, please refer to Section 11. (Default = undefined.)

• Ping Access: Enables/Disables response to the ping command. When Disabled, the MPC will not respond to Ping commands. Note that disabling Ping Access at the Network Port will not effect the operation of the Ping-No-Access Alarm. (Default = On.)

5.9.3. IP Security

The IP Security feature allows the MPC to restrict unauthorized IP addresses from establishing inbound Telnet connections to the unit. This allows you to grant Telnet access to only a specific group of IP addresses, or block a particular IP address completely. In the default state, the MPC accepts incoming IP connections from all hosts.

In the Text Interface, IP Security parameters are defined via item 5 in the Network Configuration menu (Figure 5.17.) In the Web Browser Interface, these parameters are found by clicking the "IP Security" link on the left hand side of the screen. In the default state, IP Security is disabled.

The IP Security Function employs a TCP Wrapper program which allows the use of standard, Linux operators, wild cards and net/mask pairs to create a host based access control list.

The IP Security configuration menus include "hosts.allow" and "hosts.deny" client lists. Basically, when setting up IP Security, you must enter IP addresses for hosts that you wish to allow in the Allow list, and addresses for hosts that you wish to deny in the Deny list. Since Linux operators, wild cards and net/mask pairs are allowed, these lists can indicate specific addresses, or a range of addresses to be allowed or denied.

When the IP Security feature is properly enabled, and a client attempts to connect, the MPC will perform the following checks:

1. If the client’s IP address is found in the "hosts.allow" list, the client will be granted immediate access. Once an IP address is found in the Allow list, the MPC will not check the Deny list, and will assume you wish to allow that address to connect.

2. If the client’s IP address is not found in the Allow list, the MPC will then proceed to check the Deny list.

3. If the client’s IP Address is found in the Deny list, the client will not be allowed to connect.

5-51

Basic Configuration

4. If the client’s IP Address is not found in the Deny list, the client will be allowed to connect, even if the address was not found in the Allow list.

Notes:

• If the MPC finds an IP Address in the Allow list, it will not check the Deny list,

and will allow the client to connect.

• If both the Allow and Deny lists are left blank, then the IP Security feature will

be disabled, and all IP Addresses will be allowed to connect (providing that the proper password and/or SSH key is supplied.)

• When the Allow and Deny lists are defined, the user is only allowed to specify

the Client List; the Daemon List and Shell Command cannot be defined.

5.9.3.1. Adding IP Addresses to the Allow and Deny Lists

To add an IP Address to the Allow or Deny list, and begin configuring the IP Security feature, proceed as follows.

Notes:

• Both the Allow and Deny list can include Linux operators, wild cards, and

net/mask pairs.

• In some cases, it is not necessary to enter all four "digits" of the IP Address.

For example, if you wish to allow access to all IP addresses that begin with "192," then you would only need to enter "192."

• The IP Security Configuration menu is only available when the Administrator

Mode is active.

1. Access the IP Security Configuration Menu.

a) Text Interface: Type /N [Enter] to display the Network Configuration Menu.

From the Network Configuration Menu, type 5 [Enter] to display the IP Security Menu.

b) Web Browser Interface: Click on the "IP Security" Link on the left hand side of

the screen to display the IP Security Menu shown.

2. Allow List: Enter the IP Address(es) for the clients that you wish to allow. Note that if an IP Address is found in the Allow list, the client will be allowed to connect, and the MPC will not check the Deny list.

a) Text Interface: Note the number for the first empty field in the Allow list, then

type that number at the command prompt, press [Enter], and then follow the instructions in the resulting submenu.

b) Web Browser Interface: Place the cursor in the first empty field in the

parameters menu, then key in the desired IP Address, operators, wild cards, and/or net/mask pairs.

Basic Configuration

5.9.3.2. Linux Operators and Wild Cards

In addition to merely entering a specific IP address or partial IP address in the Allow or Deny list, you may also use any standard Linux operator or wild card. In most cases, the only operator used is "EXCEPT" and the only wild card used is "ALL," but more experienced Linux users may note that other operators and wild cards may also be used.

EXCEPT:

This operator creates an exception in either the "allow" list or "deny" list.

For example, if the Allow list includes a line which reads "192. EXCEPT 192.255.255.6," then all IP address that begin with "192." will be allowed; except 192.255.255.6 (providing that this address appears in the Deny list.)

ALL:

The ALL wild card indicates that all IP Addresses should be allowed or denied. When ALL is included in the Allow list, all IP addresses will be allowed to connect; conversely, if ALL is included in the Deny list, all IP Addresses will be denied (except for IP addresses listed in the Allow list.)

For example, if the Deny list includes a line which reads "ALL EXCEPT 168.255.192.192," then all IP addresses except 168.255.192.192 will be denied (except for IP addresses that are listed in the Allow list.)

Net/Mask Pairs:

An expression of the form "n.n.n.n/m.m.m.m" is interpreted as a "net/mask" pair. A host address is matched if "net" is equal to the bitwise AND of the address and the "mask."

For example, the net/mask pattern "131.155.72.0/255.255.254.0" matches every address in the range "131.155.72.0" through "131.155.73.255."

5.9.3.3. IP Security Examples

1. Mostly Closed: Access is denied by default and the only clients allowed, are those explicitly listed in the Allow list. To deny access to all clients except

192.255.255.192 and 168.112.112.05, the Allow and Deny lists would be defined as follows:

• Allow List:

1. 192.255.255.192

2. 168.112.112.05

• Deny List:

1. ALL

5-53

Basic Configuration

2. Mostly Open: Access is granted by default, and the only clients denied access, are those explicitly listed in the Deny list, and as exceptions in the Allow list. To allow access to all clients except 192.255.255.192 and 168.112.112.05, the Allow and Deny lists would be defined as follows:

• Allow List:

1. ALL EXCEPT 192.255.255.192, 168.112.112.05

• Deny List:

1. 192.255.255.192, 168.112.112.05

Notes:

• When defining a line in the Allow or Deny list that includes several IP

addresses, each individual address is separated by either a space, a comma, or a comma and a space as shown in Example 2 above.

• Take care when using the "ALL" wild card. When ALL is included in the Allow

list, it should always include an EXCEPT operator in order to allow the unit to proceed to the Deny list and determine any addresses you wish to deny.

5.9.4. Static Route

The Static Route menu allows you to type in Linux routing commands that will be automatically executed each time that the unit powers up or reboots. In the Text Interface, the Static Route menu is accessed via item 6 in the Network Configuration menu. In the Web Browser Interface, the Static Route menu is accessed by clicking the Static Route link, located on the left-hand side of the screen.

Both the Text Interface and Web Browser Interface allow the following parameters to be defined:

• Enable: Enables/disables SNMP Polling. (Default = Off.)

Note: This item only applies to external SNMP polling of the MPC; it does not effect the ability of the MPC to send SNMP traps.

• Version: This parameter determines which SNMP Version the MPC will respond to. For example, if this item is set to V3, then clients who attempt to contact the MPC using SNMPv2 will not be allowed to connect. (Default = V1/V2 Only.)

• Read Only: Enables/Disables the "Read Only Mode", which controls the ability to access configuration functions and invoke switching commands. When Enabled ("Yes"), you will not be able to change configuration parameters or invoke other commands when you contact the MPC via SNMP. (Default = No.)

Note: In order to define user names for the MPC via your SNMP client, the Read Only feature must be disabled. When the Read Only feature is enabled, you will not be able to issue configuration commands to the MPC unit via SNMP.

• Authentication / Privacy: Configures the Authentication and Privacy features for SNMPv3 communication. The Authentication / Privacy parameter offers two options, which function as follows:

1. Auth/noPriv: An SNMPv3 username and password will be required at log in,

but encryption will not be used. (Default Setting.)

2. Auth/Priv: An SNMPv3 username and password will be required at log in, and

all messages will be sent using encryption.

Notes:

• The Authentication / Privacy item is not available when the Version parameter

is set to V1/V2.

• If the Version Parameter is set to V1/V2/V3 (all) and Authentication / Privacy

parameter is set to "Auth/Priv", then only V3 data will be encrypted.

• The MPC supports DES encryption, but does not currently support the AES

protocol.

• The MPC does not support "noAuth/noPriv" for SNMPv3 communication.

Basic Configuration

5.9.8. LDAP Parameters

The MPC supports LDAP (Lightweight Directory Access Protocol,) which allows authentication via the "Active Directory" network Directory Service. When LDAP is enabled and properly configured, command access rights can be granted to new users without the need to define individual new accounts at each MPC unit, and existing users can also be removed without the need to delete the account from each MPC unit.

This type of authentication also allows administrators to assign users to LDAP groups, and then specify which plugs the members of each group will be allowed to control at each MPC unit.

In order to apply the LDAP feature, you must first define User Names and associated Passwords and group membership via your LDAP server, and then access the MPC command mode to enable and configure the LDAP settings and define port access rights and command access rights for each group that you have specified at the LDAP server.

To access the LDAP Parameters menu, login to MPC command mode using a password that permits Administrator Level commands and then proceed as follows:

• Text Interface: Type /N and press [Enter] to display the Network Parameters Menu (Figure 5.17.) At the Network Parameters Menu, type 27 and press [Enter] to display the LDAP Parameters Menu.

• Web Browser Interface: Click on the "LDAP Parameters" link on the left hand side of the screen to display the LDAP Parameters Menu.

Notes:

• Plug access rights are not defined at the LDAP server. They are defined via

the LDAP Group configuration menu on each MPC unit and are specific to that MPC unit alone.

• When LDAP is enabled and properly configured, LDAP authentication will

supersede any passwords and access rights that have been defined via the MPC user directory.

• If no LDAP groups are defined on a given MPC unit, then access rights will

be determined as specified by the "default" LDAP group.

• The "default" LDAP group cannot be deleted.

The LDAP Parameters Menu allows you to define the following parameters:

• Enable: Enables/disables LDAP authentication. (Default = Off.)

• Primary Host: Defines the IP address or domain name (up to 64 characters) for the primary LDAP server. (Default = undefined.)

• Secondary Host: Defines the IP address or domain name (up to 64 characters) for the secondary (fallback) LDAP server. (Default = undefined.)

• LDAP Port: Defines the port that will be used to communicate with the LDAP server. (Default = 389.)

5.9.10.1. Dictionary Support for RADIUS

The RADIUS dictionary file can allow you to define a user and assign command access rights and plug access rights from a central location. The RADIUS dictionary file, "dictionary.wti" is included on the CDROM along with this user's guide. To install the dictionary file on your RADIUS server, please refer to the documentation provided with your server; some servers will require the dictionary file to reside in a specific directory location, others will require the dictionary file to be appended to an existing RADIUS dictionary file.

The WTI RADIUS dictionary file provides the following commands:

• WTI-Super - Sets the command access level for the user. This command provides the following arguments:

0 = ViewOnly

1 = User 2 = SuperUser 3 = Administrator

For example, in order to set command access level to "SuperUser", the command

line would be:

WTI-Super="2"

• WTI-Plug-Access - Determines which plug(s) the user will be allowed to access. This command provides an argument that consists of a four character string, with one character for each the MPC's switched outlets. The following options are available for each switched plug:

0 = Off (Deny Access)

1 = On (Allow Access)

For example, to allow access to Plugs 2 and 4, the command line would be:

WTI-Plug-Access="0101"

• WTI-Group-Access - Determines which plug group(s) the user will be allowed to access. The argument for this command includes a character for each, defined plug group, with the first character in the string being used to represent the first plug group defined, and the last character in the string representing the last plug group defined. The following options are available for each plug group:

0 = Off (Deny Access)

1 = On (Allow Access)

For example, to allow access to the first three defined plug groups out of a total of

six defined plug groups, the command line would be:

WTI-Group-Access="111000"

5.10. Save User Selected Parameters

It is strongly recommended to save all user-defined parameters to an ASCII file as described in Section 15. This will allow quick recovery in the event of accidental deletion or reconfiguration of port parameters.

When changing configuration parameters via the Text Interface, make certain that the MPC has saved the newly defined parameters before exiting from command mode. To save parameters, press the [Esc] key several times until you have exited from all configuration menus and the MPC displays the "Saving Configuration" menu and the cursor returns to the command prompt. If newly defined configuration parameters are not saved prior to exiting from command mode, then the MPC will revert to the previously saved configuration after you exit from command mode.

5.10.1. Restore Configuration

If you make a mistake while configuring the MPC unit, and wish to return to the previously saved parameters, the Text Interface's "Reboot System" command (/I) offers the option to reinitialize the unit using previously backed up parameters. This allows you to reset the unit to previously saved parameters, even after you have changed parameters and saved them.

Notes:

• The MPC will automatically backup saved parameters once a day, shortly

after Midnight. This configuration backup file will contain only the most recently saved MPC parameters, and will be overwritten by the next night's daily backup.

• When the /I command is invoked, a submenu will be displayed which

offers several Reboot options. Options 4 and 5 are used to restore the configuration backup file. The dates shown next to options 4 and 5 indicate the date that you last changed and saved unit parameters.

• If the daily automatic configuration backup has been triggered since the

configuration error was made, and the previously saved configuration has been overwritten by newer, incorrect parameters, then this function will not be able to restore the previously saved (correct) parameters.

To restore the previously saved configuration, proceed as follows:

1. Access command move via the Text Interface, using a username/password that permits access to Administrator level commands (see Section 5.1.1.)

2. At the MPC command prompt, type /I and press [Enter]. The MPC will display a submenu that offers several different reboot options.

3. At the submenu, you may choose either Item 4 (Reboot & Restore Last Known Working Configuration) or Item 5 (Restore Last Known Working Configuration.) Key in the number for the desired option, and then press [Enter].

Note: When invoking the /I command to restore configuration parameters, Item 4 is recommended.

4. The MPC will reboot and previously saved parameters will be restored.
