    85 to 111 ohms). The ports are IEEE 802.3 10BASE-T and IEEE 802.3u 100BASE-T compliant. The 2H23-50R has two front panel slots (5 and 6) for optional Fast Ethernet Interface Modules to support an uplink to Fast Ethernet backbones or a high speed connection to a local server.

  • Page 17: Smarttrunking

    Address Discovery (RAD) checks the device for an IP address. If one has not yet been assigned (2H23-50R IP address set to 0.0.0.0), RAD checks to see if any of the device’s interfaces have a link. If so, RAD sends out RARP and BootP requests to obtain an IP address from a server on the network.
