NETWORK POWER SWITCH

2. Introduction

2.1 Description

Network equipment sometimes locks up, requiring a service call just to flip the power switch to perform a simple reboot. The Network Power Switch gives network administrators the ability to perform this function from anywhere on the LAN/WAN, or if the network is down, to simply dial in from a modem for out-ofband power control.

NTELLIGENTPOWERCONTROL

The Network Power Switch can communicate over any TCP/IP network using generic Telnet, or out-of-band using an external modem and terminal emulation. Each outlet can be assigned an individual password, device name, reboot delay time, and unique power-up default status.

ECURITY ANDCO-LOCATIONFEATURES

Address-specific IP security masks prevent unauthorized network access to the Network Power Switch command mode. The Network Power Switch provides two password security levels: System level and User level. The System password allows access to all configuration and command functions. The User password allows access only to assigned plugs. User-level security features are ideal for co-location applications, where multiple users may be allowed plug-specific access to the Network Power Switch.

ASY TOUSE

, E

ASY TOCONFIGURE

Reboots and plug switching are controlled by simple ASCII commands sent to the Switch via network, modem, or from a local PC. Set-up and configuration is also simple; easy-to-follow menus lead you through the installation process.

2.2 Features

• Turn on or off any AC-powered device via telnet, modem, or local terminal.

• Eight individual switched outlets.

• Dual 15-Amp circuits.

• Two levels of outlet-specific password security plus network security.

CHAPTER 3: Installation

3. Installation

3.1 Option Switches

The Option Switches select default settings for the Baud Rate, Command Echo, Boot Delay, and Disconnect Timeout. Default settings selected via the Option Switches will be used when the unit is reset to default parameters as described in Section 3.7.

NOTE

Although the Option Switches select default settings for these features, operating settings can also be defined using the Network Power Switch configuration menus described in Chapter 4.

Option Switch settings are described below.

Baud Rate The default baud rate for the Console Port and Modem

Port. This rate will be selected after a power interruption, and when the unit is reset to default parameters.

Boot Delay The default Boot Delay setting. When a boot cycle is

initiated, the Boot Delay determines the length of time that the switched outlet will remain off until power is restored.

Command Echo The default setting for the Command Echo for the Console

Port, Modem Port, and Network Port. When Command Echo is enabled, commands entered at your keyboard will be sent to the Network Power Switch and echoed back to your display monitor.

Disconnect Timeout The default Disconnect Timeout value. This determines

how long the Network Power Switch will wait for additional commands before automatically disconnecting. Note that when the Network Power Switch times out, DTR will drop, and the modem disconnect string and initialize string will be sent.

NETWORK POWER SWITCH

Switch Function Up Down

1 Default Baud Rate 38.4 kbps 9600 bps (factory setting) 2 Default Boot Delay 10 sec. 5 sec. (factory setting) 3 Default Command Echo Enable Disable (factory setting) 4 Default Disconnect Timeout 30 min. 2 min. (factory setting)

3.2 Console Port Connection

The male DB9 connector, which is used for connection to a local PC or control device. The Console port is DTE, like the serial port on a PC. The Appendix describes the port interface.

3.3 Connecting an External Modem

When connecting directly to an external modem, use a standard AT-to-modem cable. Make certain the modem is initialized at the same baud rate as the Network Power Switch (Option Switch 1). The modem must be set to Auto-Answer, in one ring. Please refer to the modem user’s guide for more information. Section 4.4 describes the procedure for defining the Network Power Switch modem setup string. The Appendix describes the port interface.

3.4 Connecting the Network Cable

The Network port is an RJ-45 Ethernet jack, for connection to a TCP/IP network. Connect your 10BASE-T cable to the Network port, then complete the remainder of the installation procedure. Before attempting to access the Switch via network, please assign the IP Address, Gateway Address, and Subnet Mask as described in Section 4.6.

3.5 Power Supply Connection

The Network Power Switch includes two AC inputs. The Bus A input provides power for plugs 1 through 4. The Bus B input provides power for plugs 5 through

8. In order for the Network Power Switch to function, either Bus A or Bus B or both must be connected to the appropriate power supply.

CHAPTER 3: Installation

3.6 Connection to Switched Outlets

The main power switch must be on in order for the Network Power Switch to operate. When the Switch is powered on, the eight AC outlets will be switched on or off, as specified by the user-defined Power-Up Default (see Section 4.5).

Each outlet can switch up to 15 Amps AC. The total for each Bus cannot exceed 15 Amps.

3.7 Reset Unit to Defaults

If Option Switch settings are changed while the Switch is powered on, new settings will not be applied until the Switch is reset to default settings. There are two ways to reset the Switch to defaults: the default parameters option and the default button (local).

NOTE

When these reset procedures are performed, all user-selected parameters, including passwords and port names, will be lost. We strongly recommend recording all menu-selected parameters before performing either of these procedures.

3.7.1 D

EFAULTPARAMETERSOPTION

This method allows default parameters to be set without affecting the On/Off status of the Network Power Switch’s eight switched plugs. To reset the Switch to default parameters:

1. Access the Network Power Switch Command Mode (see Section 4.2 or 5.1).

2. At the NPS> command prompt, type /G and press [Enter]. The General

Parameters menu will appear.

3. From the General Parameters menu, type A and press [Enter]. The unit will display the “Default Parameters?” prompt. Type Y and press [Enter] to proceed with the reset procedure. After a brief pause, parameters will be reset to default values.

Typically, this method is used when devices have not been connected to the Network Power Switch, and you have immediate access to the installation site.

NOTE

This method will temporarily switch all plugs off.

Set the Master Power Switch to the off position. Press and hold the Default Button on the back panel. Place the Master Power switch in the on position. Wait about 5 seconds, and then release the Default Button.

CHAPTER 4: Configuration

4. Configuration

4.1 System Mode and User Mode

In order to restrict access to sensitive command functions, the Network Power Switch features two separate operating modes: System Mode and User Mode.

System Mode allows access to all configuration menus, command functions, and status screens. When System Mode is active, Boot/On/Off commands can be directed to any of the Network Power Switch’s eight switched outlets. The System Status Screen shows On/Off conditions and user passwords for all eight switched outlets, and lists system parameters including network configuration and modem setup. In addition, System Mode also allows access to all system configuration functions.

User Mode allows limited access to command functions and status screens; users are not allowed to access configuration menus. When User Mode is active, Boot/On/Off commands can only be directed to the specific outlets that are “owned” by that individual user. Outlets owned by other users cannot be switched. The User Status Screen only shows conditions at the outlets owned by the user; system parameters are not displayed.

When properly configured, the Network Power Switch will display a password prompt when the Switch is contacted via the Console Port, Modem Port, or Network Port. The password entered at this prompt determines whether the Switch will start up in System Mode or User Mode. If the System Password (defined via the General Parameters menu) is entered, the System Mode will be active. If the User Password (defined via the Plug Configuration Menus) is entered, the User Mode will be active.

Note that if the System Password is not defined, the Network Power Switch will not display the password prompt, and will always start up in System Mode. Once the System Password has been defined, individual users can be granted access to specific outlets by assigning passwords to each plug as described in Section 4.5.

NETWORK POWER SWITCH

4.2 Communicating with the Network Power Switch

In order to configure the Network Power Switch or invoke command functions, you must first connect to the Network Power Switch and access command mode.

1. The Network Power Switch is transparent to parity and will accept 7-bit or 8-bit characters, but will always answer back at 8 bits, no parity. Make certain your communications program (for example, ProComm

or HyperTerminal) is set

for the appropriate baud rate, bits, and parity.

a) Via Modem: Start your communications program. Dial the external

modem connected to the Network Power Switch. Wait for the Connect message and proceed to step 2.

b) Via Local PC: Start your communications program and then press

[Enter].

c) Via Network: During initial configuration, the Network Power Switch

cannot be accessed via the Network Port. After network parameters (such as the IP Address) have been defined as described (see Section 4.6), the unit may then be accessed via network as described in Section 5.1.

2. Password: If the System Password has been defined, the Switch will display the Password Prompt. Key in either the System Password or User Password, and press [Enter]. If the system password has not been defined, the prompt will not be displayed.

NOTE

The Password feature is case-sensitive. If you forget the System Password, contact the Network Power Switch

via the Console Port. When the password prompt appears, press the default button to bypass the password requirement. When the NPS> prompt appears, type /G and press [Enter] to access the General Parameters menu. Use the General Parameters menu to review or change the system password.

Since 255 is a wild card, Mask 1 blocks all IP address. Mask 2 then grants access to all addresses that begin with 192. Finally, Mask 3 specifically blocks access by

192.1.1.5.

NOTE

Mask #5 has priority over the other four masks. If Mask #5 is set to deny access by “255.255.255.255” (all wild cards), all IP Addresses will be blocked, and you will not be able to access the Network Power Switch Command Mode via network. Access will only be allowed via the Console Port or Modem Port.

When using the wild card address “255.255.255.255” to block access by all IP Addresses, make certain that at least one higher priority mask permits access by your IP address.

4.7 Save Configuration Parameters

After the unit has been completely configured, save the parameters to an ASCII file as described in Chapter 6. This allows quick recovery in case the unit is reset to default parameters, or the configuration is accidentally deleted or altered.

CHAPTER 5: Operation

5. Operation

Your PC or Control Device must send ASCII characters at the same data rate as the Network Power Switch. The Switch accepts 8 bits with no parity, or 7 bits with even or odd parity, but will always answer back at 8 bits, no parity.

5.1 Access the Network Power Switch Command Mode

In order to invoke commands, you must first access the Network Power Switch Command Mode. Commands can be sent to the Network Power Switch via Network or modem, or from a local PC connected directly to the Console port. To access the Command Mode:

1. Contact the Network Power Switch:

a) Via Network: Telnet to the Network Power Switch’s IP Address. For

example, assuming the IP Address is 192.1.1.1, on a UNIX

system the

Telnet command would be invoked as:

$ telnet 192.1.1.1 [Enter]

NOTE

If the Telnet connection to the Network Power Switch is refused, this probably means that the Switch is busy, or that the IP Security feature has denied the connection.

b) Via Modem: Start your communications program (for example,

ProComm or HyperTerminal). Dial the external modem that is connected to the Network Power Switch. Wait for the Connect Message.

c) Via Console Port: Start your communications program (for example,

ProComm or Hyper Terminal) and press [Enter]. Make certain that you are communicating via the COM port that is connected to the Network Power Switch.

2. Password: If the System password has been defined, a prompt will be displayed. Key in your System or User Password, and press [Enter].

3. Disconnect: To end the session, type /X and press [Enter] (or disconnect using Telnet software).

NETWORK POWER SWITCH

5.2 Displaying Plug Status

The Status Screens display the On/Off state and user-defined parameters for the switched plugs. There are two Network Power Switch Status Screens: the System Status Screen and the User Status Screen.

The System Status Screen (Figure 6) lists On/Off status and parameters for all eight plugs. Communication settings, modem commands, network parameters, and other functions are also listed. Note that in System Mode, the /S command will also accept an argument that will display the User Password for each plug. To display plug passwords, access the System Mode, then type /SP and press [Enter].

The User Status Screen (Figure 7) only lists the On/Off status and parameters for the plugs owned by the User’s password. Communication parameters and other Network Power Switch functions are not listed.

CHAPTER 5: Operation

5.3 Boot/On/Off Commands

These commands are used to Boot or change the On/Off status of the Network Power Switch’s eight switched plugs. Commands can be applied to one, several, or all owned plugs. Plugs may be specified by name or number.

NOTE

When User Mode is active, commands will only be applied to plugs owned by the User’s password. Commands will not affect plugs owned by other users.

When the System Mode is active, commands can be applied to all eight switched plugs.

Wait for the NPS> prompt before entering commands. The prompt will not reappear until the previous command is complete.

If an invalid command or parameter is entered, the Network Power Switch will respond with the “?” message.

Commands are not case-sensitive. All commands are invoked by pressing [Enter].

1. Switch Plug(s) On: To power-on a plug, type /ON n [Enter]. “n” is the number

or name of the desired plug. For example:

/ON 1 or /ON ROUTER

2. Switch Plug(s) Off: To power-off a plug, type /OFF n [Enter]. “n” is the number or name of the desired plug. Note that the “/OFF” command can also be entered as “/OF”. For example:

/OFF 5 or /OF ROUTER

3. Boot Plug(s): To initiate a Boot cycle, type /BOOT n [Enter]. “n” is a the number or name of the desired plug. Note that the “/BOOT” command can also be entered as “/BO”. For example;

/BOOT 3 or /BO ATMSWITCH

Note that the Network Power Switch will display a series of periods (dots) while a Boot cycle is in progress.

NETWORK POWER SWITCH

5.3.1 A

PPLYINGCOMMANDS TOSEVERALPLUGS

Boot/On/Off commands can be applied to one plug, several plugs, a range of plugs, or all plugs as described below:

NOTE

When commands are applied to several plugs, the Network Power Switch will delay for approximately 1 second between plug operations. For example, when switching all plugs On, the Network Power Switch will switch Plug 1 On, delay one second, switch Plug 2 On, delay one second, etc.

1. Single Plug: To apply a command to a single plug, enter the number or name for that plug. For example:

/ON 3 or /ON ROUTER

2. Several Plugs: To apply a command to several plugs, enter plug names or numbers with each name/number separated by a plus sign or a space. For example:

/OFF 1+3+7 or /OF ROUTER DSU/CSU

3. Range of Plugs: To apply a command to several plugs in sequence, enter the plug names or numbers with each name/number separated by a colon (:). For example:

/BOOT 1:4 or /BOOT ROUTER:DSU/CSU

4. All Plugs: To apply a command to all owned plugs, enter an asterisk in place of the name or number. For example:

/ON * or /BO *

5. Plugs with the Same Name: If you have assigned an identical plug name to several plugs, all such plugs can be addressed with one command. For example, if plugs 3, 4, and 5 have been named “ATMSWITCH”, then all three plugs can be switched with the same command as shown below:

/ON ATMSWITCH or /BOOT ATMSWITCH

CHAPTER 5: Operation

5.4 The Default Command

The Default Command (/D) sets all plugs to their default On/Off status. The default status is set using the Plug Parameters menus described in Section 4.5. Plugs will be set to these defaults when /D is invoked, or after a power interruption. To set all plugs to defaults, type /D and press [Enter].

NOTE

When User Mode is active, this command will only be applied to plugs owned by the User’s password. The command will not be applied to plugs owned by other passwords.

When the System Mode is active, this command will be applied to all eight plugs.

This command will always be applied to all owned plugs. It cannot be applied to only one plug.

5.5 Other Commands

5.5.1 LOGI

NASDIFFERENTUSER

The /R command is used to re-log-in using a different password. When invoked, the Network Power Switch will display the password prompt, allowing you to enter a different password in order to access other ports or command functions. The /R command can be used to switch from User Mode to System Mode.

Note that although this command is not listed in the User Help Screen, it is available in both System Mode and User Mode. To log in as a different user, type

/R, press [Enter], and then key in a different valid password at the prompt.

5.5.2 R

ESETNETWORKPORT

The /T command is used to reset the Network Power Switch Network Port. When the /T command is invoked, the Network Power Switch will re-initialize its network card. The /T command is not available in User Mode. To reset the Network Port, type /T and press [Enter].

5.5.3 E

XIT/DISCONNECT

To exit from the Network Power Switch Command Mode and discontinue connection to the unit, type /X, and press [Enter]. The Network Power Switch will display the “DISCONNECT” message.

NETWORK POWER SWITCH

5.6 Operating Tips

When connecting the the Network Power Switch via network, modem, or console port, keep in mind:

1. One Connection at a Time: Only one port can access the command mode at a time. When a command port is busy, the Network Power Switch will react as follows:

a. Network Port Busy: If a second user attempts to connect via the Modem

Port, the Network Power Switch will send a busy message. If a second user attempts to connect via the Console Port, the port will not wake.

b. Modem Port Busy: If a second user attempts to connect via the Network

Port, the connection will be refused. If a second user attempts to connect via the Console Port, the port will not wake.

c. Console Port Busy: If a second user attempts to connect via the Network

Port, the connection will be refused. If a second user attempts to connect via the Modem Port, the Console Port will disconnect and the Modem Port will be granted access; the Modem Port has priority over the Console Port.

2. Ping Packet Size: The Network Power Switch will not accept Ping Packets larger than approximately 1000 bytes.

If you have any questions about configuring or operating the Network Power

Switch, please contact Black Box Technical Support at 724-746-5500.

CHAPTER 6: Saving and Restoring Configuration Parameters

6. Saving and Restoring

Configuration Parameters

After you’ve properly configured the Network Power Switch, you can download parameters and save them as an ASCII text file. Later, if the configuration is accidentally altered, the file with the saved parameters can be uploaded to automatically reconfigure the unit without manually assigning each parameter.

You can upload saved parameters to other Network Power Switches. This allows

rapid setup when you’re configuring several units with the same parameters.

You can perform the “Save Parameters” procedure from any terminal emulation program (for example, ProComm, Crosstalk, HyperTerminal, etc.) that allows downloading of ASCII files.

6.1 Sending Parameters to a File

1. Start your communications program and access the Network Power Switch command mode using the System Level Password.

2. When the Network Power Switch command prompt appears, type /DL and press [Enter]. The Network Power Switch will prompt you to prepare your communications program. Set up your communications program to receive and ASCII download, and specify a name for the file that will receive the saved parameters (for example, NPS.PAR).

3. When the communications program is ready to receive the file, return to the Network Power Switch command mode, and press [Enter] to proceed.

4. The Network Power Switch will send a series of ASCII command lines that specify the currently selected Network Power Switch parameters.

6.2 Restoring Saved Parameters

This section describes how to use ProComm to send saved parameters to the Network Power Switch.

1. Start your communications program and access the Network Power Switch command mode using the System Level Password.

2. Configure your communications program to upload an ASCII text file.

NETWORK POWER SWITCH

3. Upload the file with the saved parameters. If necessary, key in the file name and directory path.

4. When the upload is complete, make certain to terminate the communications program’s upload mode.

NOTE

The current On/Off status of each Network Power Switch plug will not be saved or restored. However, the selected default On/Off setting for each plug will be saved and restored.

When the configuration file is sent to the Network Power Switch via telnet, the unit’s IP Address, Subnet Mask, and Gateway Address cannot be altered.

5. Type /SP and press [Enter]. The Network Power Switch will display the Status Screen with passwords revealed. Check the Status Screen to make certain that saved parameters have been restored.
