Rp And Rsp7000 Configurations; Configuring Jumpers - Cisco 7000 Series Hardware Installation And Maintenance Manual

RP and RSP7000 Configurations

This section describes the following maintenance aspects of the RP and RSP7000, with differences
noted:
•
Changing RP jumper settings
Note
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.

Configuring Jumpers

The RP contains the hardware configuration register and the Flash memory write-protect jumper,
both of which are shown in Figure 5-4. Jumpers installed on the hardware configuration register
define boot instructions and set broadcast addresses and console baud rates. Jumper J2, when
removed, protects the contents of Flash memory by preventing any information to be written to Flash
memory. Jumpers J3 and J4 (see Figure 5-4) are set according to the size of the eight software
EPROMs on the RP. These jumpers correspond to the EPROMs only and not to the software image
size; you do not need to reset the jumpers when loading a larger software image into Flash memory.
(See Figure 5-8 for jumper settings.)
