    INSTALLATION CHAPTER 3: INSTALLATION Mechanical Installation 3.3.1 DIN-Rail Mounting the Multilink ML1200 The Multilink ML1200 is designed for use in a “factory floor” industrial environment. It is available with optional DIN-Rail brackets to mount it securely in a metal factory floor enclosure, maintained vertically for proper convection cooling of the unit.
  • Page 55 CHAPTER 3: INSTALLATION INSTALLATION For best cooling of the ML1200, attach the metal brackets to metal (rather than wood or plastic). Attaching to metal helps conduct heat away from the ML1200 through the metal brackets and into the metal support structure. Since the ML1200 has special internal thermal techniques (patent pending) to move the heat generated by the electronic components inside into the case, the case may be quite warm to the touch during normal operation.

  • Page 165: Tag Vlan Vs. Port Vlan

    CHAPTER 10: VLAN VLAN If VLANs are entirely separate segments or traffic domains - how can the VLANs route traffic (or “talk”) to each other? This can be done using routing technologies (e.g., a router or a L3-switch). The routing function can be done internally to a L3-switch. One advantage of an L3 switch is that the switch can also support multiple VLANs.
  • Page 166 VLAN CHAPTER 10: VLAN 802.1Q VLANs aren't limited to one switch. VLANs can span many switches. Sharing VLANs between switches is achieved by inserting a tag with a VLAN identifier (VID) into each frame. A VID must be assigned for each VLAN. By assigning the same VID to VLANs on many switches, one or more VLAN (broadcast domain) can be extended across a large network.

To utilize the capabilities of GVRP, GE Multilin recommends that the user become familiar with the concepts and capabilities of IEEE 802.1q.

    There must be one common VLAN (that is, one common VID) connecting all of the GVRP- Note aware devices in the network to carry GVRP packets. GE Multilin recommends the default VLAN (DEFAULT_VLAN; VID = 1), which is automatically enabled and configured as untagged on every port of the MultiLink ML1200 Managed Field Switch.

Rapid Spanning Tree Protocol (RSTP) (IEEE 802.1w) is an evolution of the Spanning Tree Protocol (STP) (802.1d standard) and provides for faster spanning tree convergence after a topology change.
  • Page 210 Even though RSTP inter-operates with STP, RSTP is more efficient at establishing the network path and network convergence in case of a very fast failure. As such, GE recommends that all network devices be updated to support RSTP. RSTP offers convergence times typically less than one second.
  • Page 211 CHAPTER 13: RAPID SPANNING TREE PROTOCOL RAPID SPANNING TREE PROTOCOL Under some circumstances, it is possible for the rapid state transitions employed by RSTP to result in an increase in the rates of frame duplication and the order in which the frames are sent and received. To allow RSTP switches to support applications and protocols that may be sensitive to frame duplication and out of sequence frames, RSTP may have to be explicitly set to be compatible with STP.
