Versatile Interface Processor Functions VIP Port Adapter Hardware Configuration Overview The port adapter attaches to the VIP motherboard. (See Figure 7.) The port adapter contains the physical connections for the VIP interface types to connect to your network.
Versatile Interface Processor Functions Note VIP-FE-TX is a fixed configuration. The FE-TX port adapter is not available as a spare part. The entire VIP-FE-TX assembly is a FRU. The FE-TX port adapter has a handle attached, but this handle is not shown to allow a full view of the detail on the port adapter’s faceplate. Caution To prevent system problems, do not remove port adapters from the VIP motherboard or attempt to install other port adapters on the VIP motherboard.
Versatile Interface Processor Functions VIP Installation Prerequisites This section provides a list of parts and tools you will need to perform the installation, and it also includes safety and ESD-prevention guidelines to help you avoid injury and damage to the equipment. This section also provides a detailed description of the OIR function to help you perform online installation successfully and avoid error message and system restarts.
Versatile Interface Processor Functions Preventing Electrostatic Discharge Damage Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. A processor module comprises a printed circuit board that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and a handle are integral components of the carrier.
Versatile Interface Processor Functions Online Insertion and Removal—An Overview The OIR feature allows you to remove and replace a VIP board while the system is operating; you do not need to notify the software or shut down the system power. Note The VIP port adapters themselves do not support OIR, nor are they FRUs.
Versatile Interface Processor Functions The function of the ejector levers (see Figure 9) is to align and seat the card connectors in the backplane. Failure to use the ejector levers and insert the interface processor properly can disrupt the order in which the pins make contact with the card or interface processor.

Versatile Interface Processor Functions VIP Installation The following sections describe the procedures for removing or installing a VIP in the Cisco 7000 series and Cisco 7500 series routers. The functionality is the same for each router model; therefore, the term the chassis will be used except where specific model issues arise. The OIR function allows you to install and remove a VIP without first shutting down the system; however, you must follow the instructions carefully.
Versatile Interface Processor Functions Figure 10 shows proper handling of an interface processor during installation. Handling Processor Modules for Installation and Removal (Horizontal Orientation Shown) H4714 Figure 10 Captive installation screws To remove a VIP, follow these steps: Step 1 If you are replacing a failed VIP, disconnect all cables from the VIP ports; however, if you are only moving a VIP to another slot, this step is not necessary.
Versatile Interface Processor Functions Installing a VIP The VIP slides into the open interface processor slot and connects directly to the backplane. The interface processors are keyed to guide pins on the backplane, so the VIP can be installed only in an interface processor slot. Figure 9 shows the functional details of inserting an interface processor and using the ejector levers. Figure 10 shows proper handling of an interface processor during installation.
Versatile Interface Processor Functions Checking the Installation and Verifying VIP Status You can use the configure command to configure a VIP interface. To use the configure command, enter the privileged level of the EXEC command interpreter with the enable command. The system will prompt you for a password if one has been set. The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>).
Versatile Interface Processor Functions Note When a new VIP is inserted or when a VIP is moved to a new slot, the system recognizes the new interfaces, but leaves them in a shutdown state until you configure them and change their state to up with the configure command. The following example display shows the events logged by the system as a new VIP-FE-TX is inserted in slot 3.
Versatile Interface Processor Functions Step 6 If the VIP is a replacement, use the show interfaces type slot/port adapter/port or show controllers cbus command to verify the status of the interfaces. (Refer to the section “Verifying VIP Status Using show Commands” on page 22.) If you replaced a VIP with a new VIP with a greater number of ports (for example, if you replaced a one-port VIP with a two-port VIP), the system will recognize the first interface, but will not recognize the additional interface.
Versatile Interface Processor Functions The show controllers cbus command displays the internal status of each interface processor, including the slot location, the card hardware version, and the currently-running microcode version. It also lists each interface (port) on each interface processor including the logical interface number, interface type, physical (slot/port adapter/port) address, and hardware (station address) of each interface.
Versatile Interface Processor Functions Upgrading VIP Microcode The Cisco 7000 series and the Cisco 7500 series support downloadable microcode, which enables you to upgrade microcode versions without having to physically replace the microcode Flash memory device on the board. You can download new microcode versions and store multiple versions in Flash memory, and you can boot from them just as you can with the system software images.
Versatile Interface Processor Functions Follow these steps to download (copy) a microcode version from a TFTP server to Flash memory. Step 1 To display the total amount of Flash memory present, its location, any files that currently exist in Flash memory and their size, and the amount of Flash memory remaining, use the show flash command. Following is an example of the output that is displayed: Router# show flash -#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name 1 ..
Versatile Interface Processor Functions Step 5 To ensure that the new microcode is used when you reboot the system, add the appropriate commands to the configuration file. To modify the configuration file, enter the configure terminal command, as follows: Router# config t Enter configuration commands, one per line. Router(config)# End with CNTL/Z. Step 6 Specify that you are changing the microcode for the VIP (microcode vip), and that it will load from Flash memory (flash).
Versatile Interface Processor Functions Upgrading and Replacing DRAM SIMMs VIPs are shipped with 8 MB of DRAM as the default memory configuration. Depending on memory requirements, you might need to upgrade the amount of DRAM by replacing the DRAM SIMMs on the VIP. You also might need to replace a single SIMM in the case of a diagnosed DRAM SIMM failure. Note DRAM SIMMs should be upgraded or replaced in the field by a Cisco-certified maintenance provider. Both DRAM SIMMs are replaced for all upgrades.
Versatile Interface Processor Functions Following is the procedure for replacing or upgrading DRAM SIMMs. Step 1 Attach an ESD-preventive wrist strap between you and an unpainted chassis or VIP surface. Step 2 Disconnect all cables from the VIP and remove it from the chassis using the procedure in the section “Removing a VIP” on page 17. Step 3 Place the VIP on a flat surface (preferably an antistatic mat or foam), and turn it so the face plate is away from you and the connector edge is toward you.
Versatile Interface Processor Functions Step 5 Remove a SIMM by pulling outward on the connectors to unlatch it, as shown in the enlargement in Figure 13. Be careful not to break the holders on the SIMM connector. Figure 13 Removing and Replacing DRAM SIMMs Faceplate edge of the system card Pull the tabs away with your thumbs, bracing your forefingers against the posts. Raise the SIMM to a vertical position.
FE-TX Port Adapter Functions FE-TX Port Adapter Functions The following sections discuss the FE-TX port adapter, which is shown in Figure 14.
FE-TX Port Adapter Functions IEEE 802.
FE-TX Port Adapter Functions Table 1 lists the cabling specifications for 100-Mbps Fast Ethernet transmission over UTP and STP cables. Table 2 summarizes IEEE 802.3u 100BASE-T physical characteristics. Table 1 Parameter Specifications and Connection Limits for 100-Mbps 100BASE-T Transmission RJ-45 MII 1 UTP2, 22 to 24 AWG3 Category 3, 4, or 5, 150-ohm UTP or STP, or multimode optical fiber Cable specification Category 5 Maximum cable length – 0.5 m (1.64 ft.
FE-TX Port Adapter Functions The bank of three status LEDs indicates the following: • • MII—On when the MII port is selected as the active port by the controller. • RJ-45—On when the RJ-45 port is selected as the active port by the controller. Link—When the RJ-45 port is active, this LED is on when the FE-TX port adapter is receiving a carrier signal from the network. When the MII port is active, this LED is an indication of network activity, and it flickers on and off proportionally to this activity.
FE-TX Port Adapter Functions Table 3 FE-TX RJ-45 Connector Pinout Pin Description 1 Receive Data + (RxD+) 2 RxD– 3 Transmit Data + (TxD+) 6 TxD– Note Referring to the RJ-45 pinout in Table 3, proper common-mode line terminations should be used for the unused Category 5, UTP cable pairs 4/5 and 7/8. Common-mode termination reduces the contributions to electromagnetic interference (EMI) and susceptibility to common-mode sources.
FE-TX Port Adapter Functions The MII receptacle uses 2-56 screw-type locks, called jackscrews (shown in Figure 20), to secure the cable or transceiver to the MII port. MII cables and transceivers have knurled thumbscrews (screws you can tighten with your fingers) that you fasten to the jackscrews on the FE-TX port adapter’s MII connector. Use the jackscrews to provide strain relief for your MII cable.
FE-TX Port Adapter Functions Attaching FE-TX Port Adapter Interface Cables On a single 100BASE-T port adapter, you can use either the RJ-45 connection or the MII connection. If you have two FE-TX, 100BASE-T port adapters on your VIP, you can use the RJ-45 connection on one and the MII connection on the other. Note RJ-45 and MII cables are not available from Cisco Systems; they are available from outside commercial cable vendors.
FE-TX Port Adapter Functions Step 2 Attach the ferrite bead to the RJ-45 cable (at either end), as shown in Figure 22. Caution The ferrite bead prevents electromagnetic interference (EMI) from affecting the FE-TX-equipped system and is a required component for proper system operation.
FE-TX Port Adapter Functions Note The configure command requires privileged-level access to the EXEC command interpreter, which usually requires a password. Contact your system administrator, if necessary, to obtain EXEC-level access. Selecting Chassis Slot, Port Adapter, and Fast Ethernet Interface Port Numbers The following section describes how to identify chassis slot, port adapter, and Fast Ethernet interface port numbers.
FE-TX Port Adapter Functions Interface ports on the VIP maintain the same address regardless of whether other interface processors are installed or removed. However, when you move a VIP to a different slot, the first number in the address changes to reflect the new slot number. Figure 23 shows some of the slot port adapter and interface ports of a sample Cisco 7505 system.
FE-TX Port Adapter Functions Configuring the FE-TX Port Adapters—Descriptions and Examples Following are descriptions and examples of the commands for configuring the FE-TX interface 3/0/0 (slot 3, port adapter 0, Fast Ethernet interface port 0). Descriptions are limited to fields that are relevant for establishing and verifying the configuration. After configuring the new FE-TX interface, use show commands to display the status of the new interface or all interfaces, or to verify changes you have made.
FE-TX Port Adapter Functions The RJ-45 connection is the default. To change to an MII connection and then verify it, use the following series of commands, including the media-type configuration command: Router# config t Enter configuration commands, one per line. Router(config)# int fa 3/0/0 Router(config-if)# media-type mii Router(config-if)# ^Z End with CNTL/Z.
SELV Circuit Warning Translations SELV Circuit Warning Translations Warning The ports labeled “Ethernet,” “10BaseT,” “Token Ring,” “Console,” and “AUX” are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because the BRI circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the telephone network voltage (TNV) circuits.
