  • Page 24: Community Names

    COMMUNITY NAMES When using Local or Remote management tools to access the EMME, it is important that the network manager has the ability to maintain network security. Community names provide some network security by serving as passwords to the device and the software running it. The network manager (super user) establishes three (3) passwords, each of which controls varying levels of access to the hardware and software.

  • Page 25: Management Information Base (Mibs)

    1.8.1 Management Information Base (MIBs) The MIBs are a database which are resident on the network device (i.e., EMME). Objects in the information base are uniquely identified by administratively assigned identifiers (called object identifiers or OIDs) and can be viewed, retrieved, or changed using an SNMP packet exchange over the network or locally using MIB Navigator.

    CHAPTER 3: INSTALLING THE EMME SETTING THE EMME MODE SWITCHES The bank of dip switches located at the top right of the EMME (shown in Figure 3-1) should be set to their default positions when the module is shipped. Check these switches to ensure that they are in the correct position for normal operation of the EMME.
  • Page 46 Switches should be positioned as follows: Never adjust switch settings on the EMME while there is power applied to it. Slide the EMME out of the chassis and WARNING change the switch as needed to select a function. The function is initiated when the EMME is reinstalled.
  • Page 47 Ensure that a BOOTP server has been configured prior to NOTES changing the switch 6 position. When the state of switch 6 is changed, the EMME will begin requesting a BOOTP server in an attempt to get a flash image download. The EMME’s BOOT PROM inhibits the sequence and the EMME requests an IP address and a filename from the BOOTP server.
