    1.1.16 UPS Monitoring The TRMM-4 can monitor an Uninterruptible Power Supply (UPS). The devices are connected via a special cable from the TRMM-4 COM port to the UPS. See the TRMM-4 Local Management User’s Guide for details about configuring the COM ports to support UPS monitoring.

  • Page 28: Telnet

    The UPS COM port configuration supports a monitoring connection for an Uninterruptible Power Supply (UPS). After using a DB9-to-RJ45 cable to connect the UPS and the TRMM-4, a MIB tool can be used to get specific information about the state of the UPS.

    Ring 4 2.2.2 Forced Network Download Any repositioning of Switch 6 will cause the TRMM-4 to initiate a BootP server forced network download. If no BootP server responds, the TRMM-4 will continue to send BootP requests until it is reset. Upon reset, it will send BootP requests (less than eleven times).

  • Page 34: Clearing Nvram

    The TRMM-4 treats the configuration setting of single ring MIMs differently than port switching MIMs. 2.3.1 Single Ring MIMs The TRMM-4 does not override the settings of single ring MIMs. The TRMM-4 reads the configuration settings of the jumpers/switches on single ring MIMs and implements them.
