Chapter 1 Installing the Expansion Module Complete the steps in this chapter to install any of the following expansion modules in an ARN: • • • • • Ethernet Token Ring Tri-Serial Ethernet/Tri-Serial Token Ring/Tri-Serial Although each expansion module type looks slightly different, you install them identically onto the ARN base module, as follows: 1. Open the ARN enclosure to access the component tray. 2. Attach an antistatic wrist strap. Caution: Electrostatic discharge can damage hardware.
Installing an Expansion Module in a BayStack ARN Router Opening the ARN To open the enclosure and expose the base module: 1. Be sure that power is turned off (0). 2. Unplug the power cable from the wall receptacle and from the ARN (Figure 1-1). 3. If present, unplug the redundant power supply cable from the ARN (Figure 1-1). 4. Remove all back panel console port cables. Redundant power supply cable Power cable UL Redundant Power 100-240~ 1.2A 50-60Hz UL ARN0017A Figure 1-1.

Installing an Expansion Module in a BayStack ARN Router The antistatic wrist strap directs the discharge of static electricity from your body to the router chassis, thereby avoiding discharge to sensitive electronic components. 10. Continue with the instructions for removing either the expansion slot filler panel or an existing expansion module. • To upgrade the ARN, proceed with “Removing the Filler Panel.” • To replace an expansion module, proceed with “Removing an Installed Expansion Module.
Installing the Expansion Module Insert flathead screwdriver under tabs 3 locking tabs ARN0030A Figure 1-5. Removing the Blank Panel From the Expansion Module Slot 3. With the locking tabs clear of their slots, push the filler panel in toward the component tray until you can remove the panel. Warning: The expansion slot filler panel has sharp, metallic edges; to avoid cutting your hand or fingers, handle the panel only on its surfaces, not edges. 114202 Rev.
Installing an Expansion Module in a BayStack ARN Router 4. Set the filler panel aside. To operate the ARN without the expansion module in the future, you must reinstall the filler panel. 5. Skip the next section and proceed to “Installing the Module.” Removing an Installed Expansion Module To remove an expansion module from the ARN: 1. Remove the five screws and washers that secure the expansion module to the base module (Figure 1-6). ARN0028A Figure 1-6.
Installing the Expansion Module 2. Disconnect the power cable from its connector on the expansion module (refer to Figure 1-6). Pull up on the white tabs in the connector to loosen the cable. 3. Holding the expansion module at either end of its base module connector, pull straight up to detach the connector from the base module socket. Be prepared to use some force at first, but stop pulling once the two connectors are free. 4.

Installing the Module To install the expansion module upgrade or replacement: 1. Locate the expansion module connector and five screw mounts standoffs on the ARN base module (Figure 1-8). Expansion module connector Standoff screw mounts (5) ARN0029A Figure 1-8.
Installing the Expansion Module 2. Insert the module’s interface connector panel into the front panel expansion slot (Figure 1-9). To clear the mounting screw standoffs, hold the expansion module at a 45-degree angle and slide the interface connectors into the slot facing down. ARN0051A Figure 1-9. Aligning the Expansion Module 3. 114202 Rev. A Rotate the module downward until the connectors fit into place in the expansion slot (Figure 1-10).
Installing an Expansion Module in a BayStack ARN Router ARN0027A Figure 1-10. Inserting the Expansion Module 4. Press the module all the way forward into the expansion slot, until the pins in the expansion module’s base module connector align with the base module connector socket. 5. Press down on the corners of the module at either end of the base module connector until the module connector slides securely into place. 6.

Remove the antistatic wrist strap. 2. Align the enclosure top around the base module component tray and slide the enclosure in until it meets the front panel (Figure 1-12). If you meet resistance, lift up slightly on the enclosure, and center the component tray between the enclosure edges. 3. 114202 Rev.

Installing the Expansion Module Connecting Cables To reconnect the ARN: 1. Reconnect any console or network cables that you disconnected from the front and back panel connectors. 2. Connect the appropriate cabling to the new Ethernet, token ring and/or serial interfaces: COM, STP, AUI, or 10Base-T. Refer to the Cable Guide for Routers and BNX Platforms for the cables available from Bay Networks. Figures 1-13 through 1-15 show the cable connections.
