Installing and Configuring Processor Modules

Installing and Configuring Processor Modules
This section provides installation and removal procedure for all processor modules, which include
the RP, SP, SSP, RSP7000, RSP7000CI, and CxBus interface processors. This section also includes
instructions for replacing spares on the interface processors, for configuring jumpers, and for using
basic configuration commands that you may need when setting up new interfaces.
On the RP, you can change the settings of the hardware configuration register and Flash memory
write-protection jumpers to define boot instructions, set broadcast addresses and console baud rates,
and set (or remove) write protection for the contents of Flash memory.
On the FSIP, you can replace a port adapter if one fails, and with software commands you can change
the rate or direction timing signals, change the default NRZ to NRZI format, or change the default
16-bit error correction cyclic redundancy check (CRC) to 32-bit on individual interfaces.
EPROM replacement procedures are included in this section in case replacement is necessary for
some unforeseen reason. An EPROM component on the SP (or SSP) and each interface processor
contains a default microcode image. The router supports downloadable microcode, so it is unlikely
that you will ever need to replace the microcode EPROM.
Each RP, SP (or SSP), RSP7000, RSP7000CI, and interface processor contains a bus-type connector
that mates with the system backplane. Each card connector comprises a set of tiered pins, in three
lengths. The pins send specific signals to the system as they make contact with the backplane. The
system assesses the signals it receives and the order in which it receives them to determine what
event is occurring and what task it needs to perform, such as reinitializing new interfaces or shutting
down removed ones. For example, when inserting an interface processor, the longest pins make
contact with the backplane first, and the shortest pins make contact last. The system recognizes the
signals and the sequence in which it receives them. The system expects to receive signals from the
individual pins in this logical sequence, and the ejector levers help to ensure that the pins mate in
this sequence.
Caution
remove or install the RP or SP (or SSP) while the system is powered on. Doing so can cause a system
crash and can destroy memory files.
System software upgrades also can contain upgraded microcode images, which will load
automatically when the new software image is loaded. Although most upgrades support the
downloadable microcode feature and are distributed on floppy disk or Flash memory card, some may
require ROM replacement. If replacement is necessary, refer to the section "Microcode Component
Replacement" in this chapter. Also, specific up-to-date replacement and configuration instructions
will be provided with the replacement component in the upgrade kit.

Online Insertion and Removal Information

All CxBus interface processors (AIP, CIP, EIP, FIP, FSIP, HIP, MIP, and TRIP) support online
insertion and removal (OIR), which allows you to install, remove, replace, and rearrange the
interface processors without turning off the system power. When the system detects that an interface
processor has been installed or removed, it automatically runs diagnostics and discovery routines,
acknowledges the presence or absence of the interface processor, and resumes system operation
without any operator intervention. You do not need to notify the software or shutdown the system
power.
When you remove or insert an interface processor, the backplane pins send signals to notify the
system, which then performs as follows:
