Server Tech CW-24V2-L30M Switched PDU Features:

  • Easy to use and access, secure, integral HTML Web GUI over HTTP/S, plus LDAP/S and TACACS+ external authentication and authorization support
  • Secure remote power management; reboot individual or grouped outlets (SSL, SSH, Telnet, SNMP, RS-232)
  • Outlets may be linked to one or multiple groups without loss of control of that individual outlet
  • Native power-up sequencing prevents in-rush current overload during initial start-up or after power loss. Unlike other products on the market, sequencing occurs during initial startup, after power loss and after user-initiated power cycling to prevent overload
  • True RMS input current monitor(s) on easy-to-read local LED, via network or serial connection
  • Optional temperature and humidity probes with 10-ft cords to allow sensors to be located in different locations
  • SNMP traps provide automated alerts for power and environmental conditions. Additionally, event notification is available via Syslog and email
  • Expandability: add additional outlets under one IP address through link unit
  • Local and remote notification if a branch circuit is down (FE will display on LED and through the web-based interface, SNMP and email alerts)
  • 3 Phase products have a separate LED for each phase to simplify load balancing

Question: I'm trying to log into one so that I can turn on all the power outlets. It seems that they are all powered off. I'm using hyper terminal plugged into the serial port. What am I missing?
Answer: Thank you for your inquiry. Unfortunately, detailed product support is beyond the scope of this simple FAQ. That being said, here a few thoughts. Once attached to the serial port and after pressing enter, you should see Sentry Version x.xx (where x.xx is the firmware version) followed by a user name prompt. To continue, a valid user name and password are required. If this information failed to display, check to see if a cross over cable is being used and the terminal is configured to support ANSI or VT100 at a supported data rate (300, 1200, 2400, 4800, 9600, 19200, 38400, 576000, or 11520 BPS) - 8 data bits-no parity-one stop bit and Device Ready output signal (DTR or DSR). Additional configuration information, specific commands and the factory reset procedure (if required) can be found in the product manual.
