Operations Interfaces The Sentry has two interfaces: the HTML interface accessed via the HTTP enabled Ethernet connections and the command line for serial and Telnet connections. Outlet Naming and Grouping For commands requiring an outlet name, you may specify it in one of two ways: a predefined absolute name or a descriptive name assigned by an administrator. Absolute names are specified by a period (.) followed by the tower letter, the infeed letter and outlet number.
HTML Interface The HTML interface is constructed of three major components: the System Location bar, the User/Navigation bar and the Control Screen. The System Location bar displays the Sentry’s location and IP address as well as the current Control Screen title. The User/Navigation bar displays the current user and privilege level and provides access to all HTML pages. And the Control Screen is used to display current data and allow changes to outlet states or system configuration.
Outlet Control The Outlet Control section offers access to the Individual and Group outlet control pages. From the Individual and Group pages, the user can review and manipulate power control functions for all outlets and groups assigned to the current user. Both pages include the outlets absolute and descriptive names, the Outlet Status reported to the Sentry by the outlet, the current Control State being applied by the Sentry and the outlet load in amperes.
Configuration The Configuration section offers access to all unit configuration options including Network, Telnet/HTTP, Serial Ports, Outlets, Groups, Users, FTP, Proxy/SNTP and SNMP. This section is available to administrative level users only.
Telnet/SSH The Telnet/SSH configuration page used to enable or disable Telnet and SSH support and configure the port number that the Telnet or SSH server watches.

Advanced Operations SSL Secure Socket Layers (SSL) version 3 enables secure HTML sessions between a Sentry Remote Power Manager and a remote user. SSL provides two chief features designed to make TCP/IP (Internet) transmitted data more secure: • • Authentication – The connecting client is assured of the identity of the server. Encryption – All data transmitted between the client and the server is encrypted rendering any intercepted data unintelligible to any third party.
SSH Secure Shell (SSH) version 2 enables secure network terminal sessions between a Sentry Remote Power Manager and a remote user over insecure network. SSH provides an encrypted terminal sessions with strong authentication of both the server and client, using public-key cryptography and is typically used as a replacement for unencrypted Telnet.
SNMP The Sentry family of products supports the Simple Network Management Protocol (SNMP). This allows network management systems to use SNMP requests to retrieve information and control power for the individual outlets. The Sentry includes an SNMP v1 agent supporting standard MIB I and MIB II objects. A private enterprise MIB extension (Sentry3 MIB) is also supported to provide remote power control. NOTE: For security, SNMP support is disabled by default.
Setting the trap timer The Set Traptime command sets the timer period between repeated error-condition traps. The valid range for the timer period is 1 to 65535 (in seconds). The default value for the timer period is 60 seconds. To set the trap timer: At the Sentry: prompt, type set traptime, followed by the timer period and press Enter.
SNMP Traps The Sentry supports three types of SNMP traps. Traps are enabled at the tower (T), infeed (I) or outlet (O) level. Trap Summary Name Level(s) Status T, I, O Description Operational status change Change O Control status change Load I Input load out of limit All traps include the Location of the Sentry as defined with the Set Location command. See Creating a location description in Chapter 3: Operations for more information.
Load Trap The Load trap is generated whenever the total input load on an infeed exceeds a preset threshold. Load traps include the reported input load, load status, Location of the Sentry, and identifier and name of the affected infeed. Any error state generates a Load trap and triggers the trap timer. A new trap is generated at the end of every timer period until the Load returns to a non-error status.
Enabling or Disabling a Load trap The Set Trap Infeed Load command is used to enable or disable an Infeed Load trap. To Enable or Disable a Load trap: At the Sentry: prompt, type set trap infeed load, followed by the infeed name, and on or off. Press Enter, or Type set trap infeed load all, followed by on or off and press Enter. Examples The following command enables the Load trap for second infeed on the first tower, using the infeed’s absolute name: Sentry: set trap infeed load .
