In this release memo, the Series/1 product after the upgrade is referred to as the IB/2-UG20. This release memo lists the contents of the upgrade kit, and describes the procedure for up grading your Series/1 product to an IB/2-UG20. It also describes the firmware and soft ware compatibility requirements of an IB/2-UG20. Contents of the Upgrade Kit The upgrade kit includes the following items: MCPU20 board 96-TPI disk drive "96TPI" label Six shorting plugs Two sets of M1 IECM Revision 02A PROMs Distribution diskette containing SW/20-IB Version 2.0 Release memo for M1 IECM PROMs Revision 02A Release memo for SW/20-IB Version 2.0 Internetwork Bridge Installation and Operation Guide Network Management Guide Compatibility A protocol independent product, the IB/2UG20 running SW/20-IB Version 2.0 can operate with all 3Com products. Table 1 illustrates the hardware and firmware compatibility requirements of the IB/2-UG20: Table 1 Hardware/Firmware Compatibility Product Software Boards PROMS IB/2-UG20 SW/20-IB Version 2.0 MCPU20 M3 MMON Rev. 00J or later IB/2-UG20 SW/20-IB Version 2.0 EC/2 M1 IECM Rev. 02A or later Installation Follow these instructions to upgrade your Series/1 product to an IB/2- UG20: 1. Install the 96-TPI disk drive on the Series/1 system, using the procedure described below. Refer to Figures 4 and 5 for information on the location of the components. The 96-TPI disk drive, which is manufactured by TEAC, has a product label indi- cating its model number. It may be one of the following numbers: FD-55-F FD-55-FV-03-U FD-55-FV-13-U FD-55-FR-511-U Before you install the new disk drive, verify that the drive is configured according to Figure 1, 2, or 3. After you have installed the shorting plugs, follow these steps to install the disk drive: a. Power off the Series/1 system. b. Disconnect the AC power cord of the Series/1 system. c. Remove the top cover of the Series/1 system. The cover of this unit is held in place by ball studs. Remove it by lifting each side of the back overhang with a brisk upward motion, thereby disengaging each ball stud separately. d. Disconnect the floppy power cable from the disk drive. e. Disconnect the floppy ribbon cable from the disk drive. f. The floppy disk drive assembly is mounted on the Series/1 chassis with four cross head screws at the base of the floppy disk drive support bracket. To remove the floppy disk drive assembly, unscrew the four screws, which are accessible from the underside of the chassis. g. Remove the 48-TPI disk drive from the support bracket by unscrewing the crosshead screws that attach the disk drive to the bracket. h. Apply the "96TPI" label to the front of the new disk drive as shown in Figure 4. i. Use the crosshead screws to attach the support bracket to the new drive. Be sure that the screws are installed in the upper holes, which are metric holes, on the support bracket. j. Mount the disk drive back on the Series/1 chassis. k. Reconnect the ribbon cable to the new disk drive. l. Reconnect the floppy power cable to the new disk drive. Make sure that pin 1 on the ribbon cable is connected to pin 1 on the edge connector of the disk drive. The ribbon cable has pin 1 on the side with the red edge; the connector on the drive has markings indicating the pin numbers.

Install the MCPU20 board, using the procedure described below. Refer to Figure 5, which illustrates the internal structure of the Series/1 chassis, for additional information. The only external jumper on the MCPU20 that you can alter is at position A of jumper block E77. When a shorting plug is installed at this location, the MCPU20 will repeat the self-test continuously after power on. ** CAUTION ** When installing or removing boards, make sure that you have powered off the Series/1 system. Otherwise, the boards will be damaged. a. Disconnect the floppy ribbon cable from the FDC board, which is mounted on the MCPU board. b. Remove the MCPU board from Slot C of the Series/1 chassis. c. Insert the MCPU20 board in Slot C of the Series/1 chassis, taking care to slide the left and right edges of the board in the grooves of the board guides for this slot. d. Plug the floppy ribbon cable into the 34-pin connector at the top edge of the MCPU20. Figure 5 Series/1 Chassis 3. Remove the EC/2 board from Slot B of the Series/1 chassis. 4. Install one set of M1 IECM Revision 02A PROMs on the EC/2 board according to the procedure described in the accompanying M1 IECM PROMs Revision 02A release memo. 5. Replace the EC/2 board in Slot B of the Series/1 chassis. 6. Remove the other EC/2 board from Slot H of the Series/1 chassis. 7. Install the second set of M1 IECM Revision 02A PROMs on the EC/2 board according to the procedure described in the M1 IECM PROMs Revision 02A release memo. 8. Replace the EC/2 board in Slot H of the Series/1 chassis. 9. Replace the top cover of the Series/1 system. 10. Reconnect the AC power cord to the Series/1 system. 11. If you wish to set the MCPU20 configuration parameters through the console port of the newly-configured IB/2-UG20, refer to Section 4.3.3 of the Internetwork Bridge Installation and Operation Guide for information on this procedure. MCPU20 firmware is preset at the factory for the majority of installations and probably does not need to be reconfigured. When you power on the IB/2-UG20, it begins a series of self-test diagnostics. Refer to Appendix B in the Internetwork Bridge Installation and Operation Guide for information on self-test diagnostics. ** NOTE ** Current software programs that operate with the MCPU board are not compatible with the MCPU20 board. Software Copy Before you run SW/20-IB Version 2.0 on your IB/2-UG20, make a backup copy of the SW/20-IB Version 2.0 distribution diskette. Refer to the accompanying SW/20-IB Version 2.0 release memo for this procedure.
