    Figure 3. MMC Communications Temperature and Voltage Sensors The MMC monitors the temperature and voltage of the module and provides automatic alert and shutdown, as well as restart and power control capabilities. The sensor data monitors the FRU by providing records that can be read at any point in time as directed by the Shelf Manager. Events from the sensors are sent if the sensor readings transition above or below the sensor threshold listed in Table 2 through Table 4.

  • Page 31: Chapter 4: Installation And Hot Swap Procedures

    Chapter 4: Installation and Hot Swap Procedures This chapter describes how to install or remove the Telum GE-QT on an AdvancedTCA or proprietary shelf that contains AMC bays. The Telum GE-QT module is a single-wide, full-height AMC module that complies with PICMG 3.0 platform specification for a telecommunication shelf.

  • Page 32: Hot Swap Overview

    Telum GE-QT from the carrier/shelf. Bay guide rails are the ridges in which the edges of a Telum GE-QT slide in and out of the AMC bay. The bay guide rails are attached to the component cover of the carrier. The bay guide rails may provide an ESD discharge path when the Telum GE-QT is not inserted in the bay.

  • Page 33: Inserting The Telum Ge-Qt

    Inserting the Telum GE-QT To insert a new Telum GE-QT, slide the module along the bay guide rails. Then, push in the handle to lock the Telum GE-QT into place. Perform the following steps: 1. Ground yourself before handling the module and the card. (See previous ‘‘Installation...

  • Page 34: Hot Swapping Or Removing The Telum Ge-Qt

    1. To activate the hot swap mechanism on the Telum GE-QT, pull the handle from the locked position out to only 3 mm as shown in Figure 7. Extending the handle only 3 mm requests the IPMI to disengage the module from the shelf for hot swap extraction.

  • Page 39 TxDescriptors Valid Range: 80-4096 Default Value: 256 This value is the number of transmit descriptors allocated by the driver. Increasing this value allows the driver to queue more transmits. Each descriptor is 16 bytes. N O T E Depending on the available system resources, the request for a higher number of transmit descriptors may be denied.

  • Page 40: Speed And Duplex Configuration

    If the link partner is forced to a specific speed and duplex, then this parameter should not be used. Instead, use the Speed and Duplex parameters previously mentioned to force the module to the same speed and duplex. 30 Telum GE-QT User’s Guide...

  • Page 41: Additional Configurations

    Additional Configurations The following provides information about additional configurations. Configuring the Driver on Different Distributions Configuring a network driver to load properly when the system is started is distribution dependent.
