Field-Replaceable Units Chapter 1 Cisco 7200 VXR Product Overview BCM12500 CPU at 500Mhz, Implementation 1, Rev 0.1, 512KB L2 Cache 6 slot VXR midplane, Version 2.0 Input/Output Controller This section describes five different models of I/O controllers. These models are distinguished from one another by their Ethernet interface options. Table 1-22 lists the I/O controllers by product number and describes their differences. Note For a description of the configuration commands you need to configure the different interfaces on your I/O controller, refer to the Input/Output Controller Replacement Instructions document. Table 1-22 I/O Controller Descriptions Product Number Description C7200-I/O-GE+E 1 Gigabit Ethernet and 1 Ethernet port; equipped with a GBIC receptacle for 1000 megabits per second (Mbps) operation and an RJ-45 receptacle for 10-Mbps operation. (See Figure 1-15.) C7200-I/O-2FE/E C7200-I/O-FE1 2 autosensing Ethernet/Fast Ethernet ports; equipped with 2 RJ-45 receptacles for 10/100-Mbps operation. (See Figure 1-16.) 1 Fast Ethernet port; equipped with an MII receptacle and an RJ-45 receptacle for use at 100 Mbps full-duplex or half-duplex operation. Only 1 receptacle can be configured for use at a time. (See Figure 1-17 and Figure 1-18 .) C7200-I/O Has no Fast Ethernet port. (See Figure 1-19 and Figure 1-20.) C7200-I/O-FE-MII2 1 Fast Ethernet port; equipped with a single MII receptacle. (See Figure 1-21.) 1. The Product Number C7200-I/O-FE does not specify MII because both an MII and an RJ-45 receptacle are included. 2. The I/O controller with the Product Number C7200-I/O-FE-MII has a single MII Fast Ethernet receptacle only. Although still supported by Cisco, this I/O controller with a single MII receptacle is no longer an orderable product as of May 1998. You can also identify your I/O controller model from a terminal by using the show diag slot 0 command. (See the "Viewing Your System Configuration" section on page 4-20.) The I/O controllers consist of the following components and options: • Ethernet, Fast Ethernet, or Gigabit Ethernet interface options • Dual channels for local console and auxiliary ports The console port has full data communications equipment (DCE) functionality and the auxiliary port has full data terminal equipment (DTE) functionality. • NVRAM for storing the system configuration and environmental monitoring logs Note NVRAM uses lithium batteries to maintain its contents when disconnected from power. Some I/O controllers use a static RAM (SRAM) component with an external lithium battery to provide the same functionality as the NVRAM. • Two PC Card (PCMCIA) slots that hold Flash Disks or PC Cards for storing the default Cisco IOS software image 1-32 Cisco 7200 VXR Installation and Configuration Guide OL-5013-09
