5-168 Cisco 7000 Hardware Installation and Maintenance
Installing and Configuring Processor Modules
Step 5 Enter the command microcode card-type rom to negate the instruction to load from Flash
memory.
Step 6 Enter the command microcode reload to load the new ROM microcode.
Step 7 Enter the show controller cxbus command again. The first line of the display for the
interface should show the new microcode version loaded from ROM.
The replacement procedure is complete. If the enabled LED fails to light after a second installation
attempt, or if any of the interfaces fail to return to their previous state, refer to the troubleshooting
procedures in the chapter “Troubleshooting the Installation.”
RP and RSP7000 Configurations
This section describes the following maintenance aspects of the RP and RSP7000, with differences
noted:
• Changing RP jumper settings
Note The RSP7000 uses the software configuration register feature exclusively; there are no
user-configurable jumpers on the RSP7000. For the RSP7000’s configuration register functions,
refer to the section “Software Configuration Register,” later in this chapter.
• Changing software configuration register settings
• Replacing system software EPROMs
• Replacing DRAM SIMMs
Most system software upgrades are distributed on floppy disk or Flash memory cards. However,
occasionally it might be necessary to replace the system software ROMs to ensure proper operation
with a newer software release. Also, if your RP supports 16-MB SIMMs, you can upgrade the
DRAM yourself.
Configuring Jumpers
The RP contains the hardware configuration register and the Flash memory write-protection jumper,
both of which are shown in Figure 5-4. Jumpers installed on the hardware configuration register
settings define boot instructions and set broadcast addresses and console baud rates. Jumper J2,
when removed, protects the contents of onboard Flash memory by preventing any information from
being written to Flash memory.
