Installation Ensure that you have the following items. Introduction The 4-Port Token Ring Interface provides four 4- or 16-Mbit/s connections for connecting token ring networks to the HP Router 650. Installation Ensure that you have the following items.
Installation Install interface card. Install interface card. Notes You can install the interface card without taking the system offline (that is, without switching the router off and taking all networks down)— refer to “Installing the Interface Card (System Online),” page 9. (Installing an interface card without taking the system offline is often called “hot swapping.
Installation Install interface card. 2. Open the front door of the router by pulling its lock—the round post at the upper right—to the right. Figure 1. Opening Router Door 3. Switch the power supply off by pressing the bottom of its switch (marked with “ ❍ ”). If two power supplies are installed, switch both off. 4. Connect a grounding wrist strap (one is provided with the interface card) to your wrist and to the back of the router.
Installation Install interface card. 5. Press down slightly on the insides of both locks on the old card’s bezel (see figure 2), then swing them outward until the bezel disengages (see figure 3). Figure 2. Unlocking Card Bezel Figure 3. Disengaging Card Bezel 6. Grasping the left and right edges of the bezel, pull out until the tray is about half exposed. 7. Grasping the sides of the tray, remove the card from the router. 8.
Installation Install interface card. 9. Pull the locks on the bezel outward, then push evenly on both ends until the card engages fully and the locks swing inward to about 45°. Figure 4. Installing Interface Card 10. Push the two locks evenly to close them, pressing downward slightly to secure them in place. 11.
Installation Install interface card. 15. To replace the label at the left of the slot that identifies the department or site served by the interface card, slide it out from the right. Position the new label with its shiny side facing the router, and slide it in from the right. (Additional labels are provided in the router’s accessories kit and also with each interface card.
Installation Install interface card. Installing the Interface Card (System Online) Note If you will be installing the new interface card in a slot where another interface card is not currently installed, skip steps 1 and 3. 1. Disconnect all cables from the interface card you will be removing, and save them for reconnection when you later install that card again. 2. Connect a grounding wrist strap (one is provided with the interface card) to your wrist and to the back of the router. 3.
Installation Install interface card. 4. Press down slightly on the insides of both locks on the old card’s bezel (see figure 7), then swing them outward until the bezel disengages (see figure 8). Figure 7. Unlocking Card Bezel Figure 8. Disengaging Card Bezel 5. Grasping the left and right ends of the bezel, pull out until the tray is about half exposed. 6.

Installing Interface Card 9. Push the two locks evenly to close them, pressing downward slightly to secure them in place. A self-test of the new interface card begins. 10.
Installation Install interface card. 11. Open the front door of the router by pulling its lock—the round post at the upper right—to the right. Figure 10. Opening Router Door 12. Remove the old card’s LED label strip from the position corresponding to the slot where you have installed the new interface card, then insert the LED label strip provided with the new card as far as it will go. 13. Bend the end of the label strip toward the back of the router, creating a 90° fold. 14. Close the router door.
Installation Install interface card. 15. To replace the label at the left of the slot that identifies the department or site served by the interface card, slide it out from the right. Position the new label with its shiny side facing the router, and slide it in from the right. (Additional labels are provided with the interface card, as well as in the router’s accessories kit.
Installation Connect network cables. Connect network cables. Connect the network cables as described below. You should also make sure that all network equipment and links are ready. Caution Static discharge may damage equipment. Do not touch the connector pins on the interface card or on the cable. 1. Secure the D-connector on the token ring cable to the token ring port, using the screws on the connector. Swap 1 2 3 4 Factory Test Token ring cable Trunk Coupling Unit (TCU) Figure 12.
Installation Arrange network cables. Arrange network cables. To help keep the network cables orderly—and out of the way when interface cards are being removed or installed—arrange the cables over the bars at the right of the router. These cable-management bars have slots in them that you can use for tie-wrapping the network cables. Included with each interface card is a tie-wrap that you can use to wrap the cables and then attach the bundle to the cable management bar, as shown in figure 13. Figure 13.
Prepare the router. Prepare the router. To prepare the router after installing the new interface card, you should do the following procedures, all of which are described in chapter 1 of the HP Router 650 Installation Guide: Connect a console. Plug in and verify router hardware. Configure and boot the router. Verify router initialization and configuration.
Cables and Connectors Troubleshooting For general information about troubleshooting problems using any interface card in the Router 650, refer to chapter 3 of the HP Router 650 Installation Guide. The following troubleshooting information is specific to the token ring interface card. Note In the description of the port status LEDs in chapter 2 of the HP Router 650 Installation Guide, the label “Tx” is shown for the third port status LED for each port.
