Switch Fabric Module 2 (WS-X6500-SFM2) Note The Switch Fabric Module 2 is not supported on the Cisco 7603 Internet Router. The Switch Fabric Module 2 (WS-X6500-SFM2), shown in Figure 1-24, requires a Supervisor Engine 2 and must be installed in slots 5 or 6 of the Cisco 7600 series Internet Router. For redundancy, you can install a second Switch Fabric Module 2.
Chapter 1 Product Overview Catalyst 6000 Family Modules The front panel on the Switch Fabric Module 2 has a 2-line by 20-character LCD display. The display allows you to monitor the module’s input/outport port traffic and local bus traffic. The display also displays system information. Two push buttons are used with the LCD display: • SELECT—Use this push button switch for LCD display menu selection. • NEXT—Use this push button switch to scroll to the next item on the LCD display menu.

Orange The module or port is disabled through the CLI command or the module is initializing2. Flashing orange The port is faulty and has been disabled. Off The port is not active or the link is not connected. 1. CLI = command-line interface. 2. This is a good time to verify that all LINK LEDs are functioning.
Chapter 1 Product Overview Port Addresses Physical Interface Addresses Physical port addresses specify the actual physical location of each module port on the rear of the router, as shown in Figure 1-25. (The port numbering convention is the same in the three-slot, six-slot, and nine-slot chassis.) The address is a two-part number in the format slot/port number. The first number identifies the slot in which the module is installed. Module slots are numbered from right to left starting with 1.
Chapter 1 Product Overview Hot Swapping Supervisor Engines and Modules Interface ports maintain the same address regardless of whether other modules are installed or removed. However, when you move a module to a different slot, the first number in the address changes to reflect the new slot number. For example, on a 4-port OC-12c POS OSM in slot 4 of the Cisco 7609 Internet Router, the address of the top WAN port is 4/1, and the address of the bottom WAN port is 4/4.
Chapter 1 Product Overview Hot Swapping Supervisor Engines and Modules Note Although the FlexWAN module supports hot swapping, individual port adapters do not. To replace port adapters, you must first remove the FlexWAN module from the chassis and then replace port adapters as required. When you remove or insert a module while the router is powered on and operating, the system does the following: 1. Determines if there is sufficient power for the module. 2.

Chapter 1 Product Overview OSM Technology Overview SONET1 SDH Equivalent STS-3c STM-1 STS-12c STM-4c STS-48c STM-16c 1. ANSI-defined SONET specifications SONET is not limited to optical links. Electrical specifications have been defined for single-mode fiber, multimode fiber, and CATV 75-ohm coaxial cable. OSMs currently allow transmission only over single-mode and multimode optical fiber. Transmission rates are integral multiples of 51.
