    Local Management. USING THIS GUIDE Read through this guide to completely understand the 2H28-08R capabilities and Local Management functions. A general working knowledge of Ethernet and IEEE 802.3 type data communications networks and their physical layer components is helpful when using this device.

  • Page 14: 2H28-08R Overview

    System LEDs COM Port RESET Button The 2H28-08R also has two slots (7 and 8) for optional Fast Ethernet Interface Modules. The device bridges each Ethernet segment to the other switch ports, and to the optional interface modules in port slots 7 and 8. The optional Fast Ethernet Interface Modules provide uplinks to 100BASE-TX or 100BASE-FX Fast Ethernet networks, and connectivity to 10BASE-T.

  • Page 15: Connectivity

    The 2H28-08R may be used as a tabletop unit or can be installed in a standard 19-inch rack using the supplied rack mounting hardware. The 2H28-08R has two power supplies. Both are universal ac power supplies with automatic voltage sensing that allows operation using 100–125 or 200–240 Vac, 50/60 Hz.

    Runtime IP Address Discovery (RAD) checks the 2H28-08R for an IP address. If one has not been assigned (2H28-08R default IP address set to 0.0.0.0), RAD checks to see if any of the 2H28-08R interfaces have a link. If so, RAD sends out Reverse Address Resolution Protocol (RARP) and BootP requests to obtain an IP address from a BootP server on the network.
