1. Introduction Network equipment sometimes "locks-up", requiring a service call just to flip the power switch to perform a simple reboot. The NPS 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-of-band power control.
2. Unit Description 2.1. Front Panel Figure 1: Front Panel As shown in Figure 1, the NPS front panel includes a series of LED indicators which function as follows: À ON: Lights when AC Power is applied to the NPS. Á RDY: Flashes when the NPS is ready to receive commands. Â RXD: Lights when the NPS receives commands. Ã DCD: Lights when the Modem Port detects the Carrier. Ä NET: Lights when a Telnet session is in progress. Å Bus A Indicators (1 - 4): Light when the corresponding Plug is switched On.
NPS Series - Network Power Switches, User's Guide Unit Description 2.2. Back Panel Figure 2: Back Panel (Model NPS-115 Shown) À Bus B (Plugs 5 - 8): Includes the following components: A) Power Inlet with Cable Clamp: Supplies power for plugs 5 through 8. B) Circuit Breaker: NPS-115: 15 Amps; NPS-230: 10 Amps C) Switched AC Outlets (5 - 8): Each outlet can switch up to 15 Amps (NPS-115) or 10 Amps (NPS-230). The total for all four outlets must not exceed 15 Amps for NPS115, or 10 Amps for NPS-230.
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, the NPS configuration menus can also be used to select operating parameters as described in Section 4.
NPS Series - Network Power Switches, User's Guide Installation 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 NPS (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 modem command strings. Appendix A describes the modem port interface. 3.4.
NPS Series - Network Power Switches, User's Guide Installation 3.7.1. Default Parameters Option This method allows default parameters to be set without effecting the On/Off status of the NPS's eight switched plugs. To reset the unit to default parameters, proceed as follows: 1. Access the NPS 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].
4. Start-Up / Configuration 4.1. System Mode and User Mode In order to restrict access to sensitive command functions, the NPS features two separate operating modes; System Mode and User Mode. The System Mode allows access to all configuration menus, command functions and status screens. When the System Mode is active, Boot/On/Off commands can be directed to any of the eight switched outlets.
NPS Series - Network Power Switches, User's Guide Start-Up / Configuration 4.2. Communicating with the NPS In order to configure the NPS or invoke command functions, the user must first connect to the NPS and access command mode. 1. The NPS is transparent to parity and will accept 7 or 8 bit characters, but will always answer back at 8 bits, no parity. Make certain your communication program (e.g. ProComm orHyper Terminal) is set for the appropriate baud rate, bits and parity.

5. Operation Your PC or Control Device must send ASCII characters at the same data rate as the NPS. The unit accepts 8 bits no parity, or 7 bits even or odd parity, but will always answer back at 8 bits, no parity. 5.1. Access the NPS Command Mode In order to invoke commands, the user must first access the NPS Command Mode. Commands can be sent to the NPS via Network or modem, or from a local PC connected directly to the Console Port. To access the Command Mode, proceed as follows: 1.
NPS Series - Network Power Switches, User's Guide Operation 5.2. Displaying Plug Status The Status Screens display the On/Off state and currently selected parameters for the switched plugs. To display the Status Screen, type /S and press [Enter]. Note that although the /S command is available in both User Mode and System Mode, the System Status Screen includes more information than the User Status Screen. Network Power Switch v2.04 Site: WESTERN TELEMATIC, INC.
NPS Series - Network Power Switches, User's Guide Operation When the System Mode is active, the /S command will produce the screen shown in Figure 9, which lists status and parameters for all eight plugs, along with Console Port parameters, and modem command strings. Note that in System Mode, the /S command will also accept an argument which will display the User Password for each plug. To display plug passwords, access the System Mode, type /SP and press [Enter].
NPS Series - Network Power Switches, User's Guide Operation 5.3.1. Applying Commands to Several Plugs 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 NPS will delay for approximately 1 second between plug operations. For example, when switching all plugs On, the NPS will switch Plug 1 On, delay one second, switch Plug 2 On, delay one second, and etc. 1.
NPS Series - Network Power Switches, User's Guide Operation 5.5. Other Commands 5.5.1. Login as Different User The /R command is used to re-login using a different password. When invoked, the NPS will display the password prompt, allowing the user to enter a different password in order to access other plugs or command functions.

NPS Series - Network Power Switches, User's Guide 6. Operation Saving and Restoring Configuration Parameters After the NPS has been properly configured, parameters can be downloaded and saved 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 the need to manually assign each parameter. Saved parameters can also be uploaded to other NPS units.
