Chapter 1 Installation This chapter describes how to install the HSSI module into the NETBuilder II ® base system. The HSSI module provides a single serial interface for a WAN connection in the NETBuilder II base system. It supports transmission rates up to OC1, including E3, T3, and sub-rates. NOTE: The HSSI module must be used with NETBuilder II HSSI and Single-Mode FDDI Software 6.2. For information about the software, see the NETBuilder II HSSI and SingleMode FDDI Software 6.2 Release Notes.

Installation 1-3 Installing the HSSI Module Installing the HSSI Module Use this procedure to install the HSSI module into the NETBuilder II base system. You will need a small flathead screwdriver. NOTE: There are two versions of the NETBuilder II 4-slot and 8-slot chassis. The older, singlewide versions of the NETBuilder II 4-slot and 8-slot chassis have two flipper ejectors for each module.
1-4 Installation Installing the HSSI Module 3. Insert the HSSI module into an uncovered I/O slot. Make sure the flipper ejector(s) are in an open position. Flipper open Flipper closed With the connector end toward the backplane and the board facing up (check that the labels on the connector/LED panel are right side up), grasp the left and right sides of the panel and fit the board into the I/O slot opening along the guide rails. 4. Lock the board in the slot.
Installation 1-5 Installing the HSSI Module Cabling the HSSI Module for Network Connection A SCSI-type cable connects the HSSI Module DTE connector to a Data Service Unit (DSU). Table 1-1 describes the connectors. Table 1-2 describes the pin assignments. 3Com recommends using minimum lengths of this cable, especially if you plan to use these serial lines at high speeds. The maximum cable length allowed is 50 feet.
1-6 Installation Installing the HSSI Module CAUTION: Connections between 3Com equipment and other equipment and peripherals must be made using shielded cables in order to maintain compliance with FCC, and other agency radio frequency emissions limits. All interconnection cables should be equipped with shielded connectors. The backshells of these connectors must completely surround the cable shield.
Chapter 2 Troubleshooting and Maintenance This chapter describes how to troubleshoot and maintain the HSSI module. If you are unable to resolve a problem with your HSSI module, you will need to contact a customer service representative. Refer to Appendix C, “Technical Support,” for information about who to contact in your area. Troubleshooting Startup Problems The following symptom indicates a self-test failure at startup.
2-2 Troubleshooting and Maintenance Maintaining the HSSI Module Replacing the HSSI Module If any component in the HSSI module fails, you will need to replace the entire module. The HSSI module can be hot-swapped, which means that you can safely remove and install a new one without turning off or rebooting the NETBuilder base system. To perform the following procedure, you may need a small flathead screwdriver. To replace the module, follow these steps to remove the HSSI module: 1.
