  • Page 30: Basic Operation

    5. Basic Operation 5.1. Communicating with the VMR/NPS Unit In order to control and configure the VMR/NPS, you must first connect to the unit, and access command mode. Note that, the VMR/NPS offers two separate command interfaces; the Web Browser Interface and the Text Interface. In addition, the VMR/NPS also offers three different methods for accessing command mode;...
  • Page 31 Basic Operation 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 6.8. Contact the VMR/NPS Unit: Via Local PC: Start your communications program and press [Enter]. Wait for the connect message, then proceed to Step 2. Via Network: The VMR/NPS 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.

    When installed at your network operation center or support facility, the WMU eliminates the need to individually access WTI units in order to perform firmware updates, control power switching functions, edit user accounts and perform other management and control functions.

  • Page 33: Controlling Power - Web Browser Interface

    Basic Operation 5.2. Controlling Power - Web Browser Interface When using the Web Browser Interface, switching commands are invoked via the Plug Control Screen and Plug Group Control Screen. 5.2.1. The Plug Control Screen - Web Browser Interface The Plug Control Screen lists the On/Off status of the VMR/NPS Series unit's Switched Outlets and is used to control switching and rebooting of the outlets.

  • Page 34: The Plug Group Control Screen - Web Browser Interface

    Basic Operation 5.2.2. The Plug Group Control Screen - Web Browser Interface The Plug Group Control Screen is used to send switching and reboot commands to the user-defined Plug Groups. As described in Section 6.5, Plug Groups allow you to specify a group of outlets that are dedicated to a similar purpose or client, and then direct switching commands to the group, rather than switching one plug at a time.

  • Page 35: Controlling Power - Text Interface

    Basic Operation 5.3. Controlling Power - Text Interface When using the Text Interface, all power switching functions are performed by invoking simple, ASCII commands. ASCII commands are also used to display status screens and to log out of command mode. The Text Interface includes a Help Menu, which summarizes all available commands.

  • Page 36: Switching And Reboot Commands - Text Interface

    Basic Operation 5.3.2. Switching and Reboot Commands - Text Interface These commands can be used to switch or reboot the VMR/NPS Series unit’s switched plugs, and can also be used to set plugs to the user-defined Power-Up Default values. Plugs may be specified by name or number. Notes: • If an asterisk appears in the "Status" column for any given plug, this indicates that the plug is currently busy, processing a previously issued command.
  • Page 37 Basic Operation Switch Plug(s) Off: To power-off a plug or Plug Group, type /OFF n and press [Enter]. Where "n" is the number or name of the desired plug or Plug Group. Note that the “/OFF” command can also be entered as “/OF”. For example: /OFF 2 [Enter] or /OF ROUTER [Enter] Reboot Plug(s): To initiate a Boot cycle, type /BOOT n and press [Enter].

  • Page 38: Applying Commands To Several Plugs - Text Interface

    Basic Operation 5.3.2.1. Applying Commands to Several Plugs - Text Interface As described below, switching and reboot commands can be applied to only one Switched AC Outlet, or to an assortment of outlets. Note: When switching and reboot operations are initiated, Boot/Sequence Delay times and user-defined Plug Priority values will be applied as described in Section 6.6. Switch Several Plugs: To apply a command to several plugs, enter the numbers or names for the plugs, separated by a "plus sign"...

  • Page 39: The Automated Mode

    Basic Operation 5.4. The Automated Mode The Automated Mode allows the VMR/NPS to execute switching and reboot commands, without displaying menus or generating response messages. Automated Mode is designed to allow the VMR/NPS to be controlled by a device which can generate commands to control power switching functions without human intervention.

Notes: • In order to use domain names for web addresses, DNS parameters must first be defined as described in Section 6.8.4. • The Web Browser Interface includes two separate fields that are allowed to define both an IPv4 protocol and IPv6 protocol format Primary NTP Address and Secondary NTP Address. • When the Primary NTP Address and Secondary NTP Address are defined via the Text Interface, the VMR/NPS will display a prompt that instructs the user to select IPv4 or IPv6 protocol. • The VMR/NPS allows parameters for both IPv4 and IPv6 protocols to be defined and saved. • Secondary NTP Address: Defines the IP address or domain name (up to 64 characters long) for the secondary, fallback NTP Server.

  • Page 47: The Invalid Access Lockout Feature

    Configuration Options 6.2.2. The Invalid Access Lockout Feature When properly configured and enabled, the Invalid Access Lockout feature can watch all login attempts made via SSH connection, Telnet connection, web browser or the serial SetUp Port. If the counter for any of these exceeds the user-defined threshold for maximum invalid attempts, then the corresponding port or protocol will be automatically disabled for the length of time specified by the Lockout Duration parameter.
  • Page 48 Configuration Options • SSH Protection: Enables/Disables and configures the Invalid Access function for SSH connections. When this item is enabled and excessive Invalid Access Attempts via SSH are detected, then the VMR/NPS will lock out the offending MAC address for the user-defined SSH Lockout Duration Period or until the /UL command is issued.
  • Page 49 Configuration Options • Web Protection: Enables/Disables and configures the Invalid Access function for Web connections. When this item is enabled and excessive Invalid Access Attempts via Web are detected, then the VMR/NPS will lock out the offending MAC address for the user-defined Web Lockout Duration Period or until the /UL command is issued.

  • Page 50: Syslog Messages

  • Page 68: The Boot Priority Parameter

    Configuration Options 6.6.1. The Boot Priority Parameter Normally, when an "On" or "Reboot" command is invoked, the VMR/NPS will switch on its 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.

  • Page 69: Example 2: Change Plug A5 To Priority 2

    Configuration Options 6.6.1.2. Example 2: Change Plug A5 to Priority 2 In the second Example shown in Figure 6.2, we start out with Boot Priorities for the plugs set as they were at the end of Example 1; Plug A3 is first, Plug A1 is second, Plug A2 is third, Plug A4 is fourth, and Plug A6 is sixth.

  • Page 76: Network Port Parameters

    Configuration Options 6.8.1. Network Port Parameters Note: The IP Address, Subnet Mask, Subnet Prefix, Gateway Address and DHCP status cannot be changed via the Web Browser Interface. In order to change these parameters, you must access the VMR/NPS via the Text Interface. • IP Address: (Defaults: IPv4 = 192.168.168.168; IPv6 = undefined) • Subnet Mask: (IPv4 Only; Default = 255.255.255.0) • Subnet Prefix: (IPv6 Only; Default = undefined) • Gateway Address: (Default = undefined.) • DHCP: Enables/Disables Dynamic Host Configuration Protocol. When this option is "On", the VMR/NPS will perform a DHCP request.
  • Page 77 Configuration Options • 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.
