But some common commands (such as ping and display current-configuration) can be executed in all views. 4-6 Arranging Slots and Numbering Interfaces Slot arrangement The MSR 20 series provides many types of interfaces, such as console, AUX, Ethernet, serial (synchronous/asynchronous), and asynchronous port.

Different interfaces on an interface module share the same slot number X. For every interface, Y starts from 0 and Y indicates the interface sequence on the interface module, from left to right. If you install an SIC-1FEA and an SIC-4FSW respectively in SLOT1 and SLOT2 on the AR MSR 20-20, the Ethernet interfaces are numbered as follows: Fixed Ethernet interfaces are Ethernet 0/0 and Ethernet 0/1; The Ethernet interface on the SIC-1FE is Ethernet 1/0; The Ethernet interfaces on the SIC-4FSW module are Ethernet 2/0, Ethernet 2/1, Ethernet 2/2 and Ethernet 2/3. 4-8 Table of Contents 5 Software Maintenance·······························································································································5-1 Introduction ·············································································································································5-1 Files ·················································································································································5-1 Software Maintenance Methods······································································································5-3 BootROM Menu ······································································································································5-4 Main BootROM Menu ······················································································································5-4 BootROM Submenus·······················································································································5-6 Upgrading BootROM Through Serial Port ······························································································5-9 Modifying Serial Port Parameters····································································································5-9 Upgrading BootROM ·····················································································································5-11 Upgrading Application Program Through Serial Port············································································5-12 Upgrading Application Program Through Ethernet Interface································································5-12 Configuring Ethernet Parameters··································································································5-12 Upgrading Application Program Through Ethernet Interface ························································5-14 Maintaining Application Program and Configuration Through Command Lines···································5-16 Maintaining the Router with TFTP Server ·····················································································5-16 Maintaining the Router with FTP Server ·······················································································5-18 Maintaining Application Program and Configuration File······································································5-21 Dealing with Router Password Loss ·····································································································5-24 User Password Loss······················································································································5-24 BootROM Password Loss ·············································································································5-25 Super Password Loss····················································································································5-25 Backing up and Restoring BootROM ····································································································5-25 i 5 Files Software Maintenance Introduction BootROM program file The file is used for booting application at boot. A complete BootROM file includes two segments: basic and extended. Application program file The router is available with Dual Image function. By default, the system defines and attempts to boot in order with three boot files: main, backup, and secure, provided they are available with CF card. If the router fails to boot with the secure boot file, it prompts the boot failure. For more information about the boot files, refer to section "Maintaining Application Program and Configuration File". Table 5-1 Default names and types of the boot files Boot file Main boot file Backup boot file Secure boot file main. bin backup. bin secure. bin File name M B S File type The application programs for system boot can be type M, B and S, but not type N. For example, if an M+B file exists, it is impossible to have another M or B file. If you change the file type of another file to B, the M+B file becomes a type M file. You can modify the file name of an application file in CF card using the command after it boots. You cannot modify the file type of a type S application image file, but you can modify the file type of type M/B and N application program files in the BootROM menu or using commands after the application program boots. However, you cannot modify this file or change the type of another file to S. If you change the name of the secure boot file with the rename command after the system boots, the file is removed from CF card. To use the secure boot file after that, you need to download it again. 5-1 Configuration file The file stores configuration information of the router. By default, the system defines and attempts to boot in order with three configuration files: main, backup, and default, provided they are available with CF card. If the router fails to boot with the secure boot file, it prompts the boot failure. For more information about the boot files, refer to section "Maintaining Application Program and Configuration File". [. . . ] It is normal that you feel hard when removing the memory bar, but do not overexert. Otherwise, anomalies might occur to the device Memory Bar Structure Figure 6-11 Memory bar structure Memory Bar Slot Figure 6-12 Memory bar structure Installing/Removing Memory Bar Follow the steps below to install the memory bar: Step 1: Make sure all power interfaces are shut down, and then proceed. Step 2: Align the memory bar golden finger with the slot on the main board. Step 3: Make the memory bar to form an angle of 45 degrees with the main board and insert it into the slot. [. . . ]
