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 v2c agent supporting standard MIB I and MIB II objects. A private enterprise MIB extension (Sentry3 MIB) is also supported to provide remote power control. See SNMP on page 18, for information on enabling and configuring SNMP.
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. Status trap A Status trap is generated when an error condition occurs on a tower, infeeed, Environmental Monitor or individual sensor.
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.
