Use the show version and show hardware commands to display the router’s current hardware and software configurations. The show microcode command lists the bundled microcode (and target hardware) version for each processor type. The show controller cbus command shows the microcode version you are running. The show diagbus command shows the RSP8 board’s hardware version and revision.
For additional descriptions of show commands, refer to the Configuration Fundamentals Configuration Guide and Configuration Fundamentals Command Reference publications, which are available online, on the Documentation
Note If the required system software and microcode are not available in your system, contact a customer service representative for upgrade information. (To obtain assistance, see the “Obtaining Technical Assistance” section on page 89 .)
Hardware Prerequisites
Your router’s configuration, protocols and features might require more than the 64 MB of DRAM that is shipped with the RSP8. To upgrade DRAM, see the “Replacing and Upgrading DRAM DIMMs” section on page 74.
To ensure proper operation of a system configured for HSA or HA, note the guidelines below:
•With HSA and HA, the RSP8 can interoperate with another RSP8, or with an RSP16.
•To ensure that the standby RSP8 operates properly, the active and the standby RSP8 (or the RSP8 and the RSP16) should have the same DRAM configuration and boot ROM version.
•Removing the active RSP8 while the system is operating might cause the system to crash; however, the system reloads with the standby RSP8 as the new active RSP8. To prevent system problems, do not remove the active RSP8 while the system is operating.
