    The following sections describe interface numbering, and MAC address assignments. Interface Numbering In all of the Cisco RF switches, the slot number is the chassis slot in which an Ethernet controller or an upstream switch module or downstream switch module is installed, and the logical interface number is the physical location of the interface port on an Ethernet controller.

  • Page 18: Power Supply Module

    To allow OIR, an address allocator with a unique MAC address is stored in an EEPROM on the Cisco RF switch midplane. Each address is reserved for a specific port and slot in the switch, regardless of whether an Ethernet controller or an upstream or downstream switch module resides in that slot.

  • Page 88 Cisco uBR7246VXR Universal Broadband Router Configurations A single Cisco uBR7246VXR router contains up to four Cisco uBR-MC16x (C, E, S, U, or X) line cards or Cisco uBR-MC28x (C, U, or X) line cards. This configuration uses a redundancy scheme where one protect card supports from one to four working line cards.
  • Page 89 Protection Scheme for the Cisco uBR7246VXR CMTS Figure 5-2 shows a chassis configuration using Cisco MC28C cards, two RF switches, and three upconverters. Three upconverters are required for this configuration. The Cisco uBR-MC28U cable interface line cards have onboard upconverters. Upconverters are not Note required in a configuration using this line card.
