System Bootstrap, Version 4.6(7.3)
If the display indicates that the System Bootstrap Version is an earlier version of 4.6 than
4.6(7.3), or an earlier version of 4.7 than 4.7(2.1), your RP will not support 16 MB SIMMs.
Contact a service representative for information about the RP upgrade.

Use the show diag slot command to display current hardware and diagnostic information about
the processor installed in the slot you specify. Because the RP always resides in the same (RP)
slot, specify slot 6 for a Cisco 7000 chassis. The third line of the display shows the current
hardware (HW) and board revisions. (Do not confuse the HW revision with the board revision;
you need only verify that the board revision is B0 or later.)

Slot 6:
EEPROM format version 1
Route Processor, HW rev 1.1, board revision B0
Serial number: 00809933
If the display indicates that the RP board revision is earlier than B0, your RP will not support
16 MB SIMMs. Contact a service representative for information about the RP upgrade.

The SIMMs must meet the following requirements:
— SIMMs must be the nine-module type, 16 MB x 9.
— Minimum speed is 70 ns.
— Maximum height is one inch.
All four SIMM sockets must be filled, and all must contain SIMMs of the same capacity and
speed. The RP supports only 4 MB x 9 SIMMs (for a total of 16 MB) or 16 MB x 9 SIMMs (for
a total of 64 MB). The RP does not support 32MB of DRAM because 8MB x 9 SIMMs are not
available.
Parts and Tools
In addition to the tools you need to remove and replace the RP, you will also need the following tools
and parts to replace SIMMs. If you need additional equipment, contact a service representative for
ordering information.
•
Four 16 MB x 9, 70 ns SIMMs
•
Antistatic mat or pad for the removed RP
•
SIMM extraction tool manufactured by AMP, Inc. (AMP Part Number 382264-1). The toll-free
phone number for AMP product information is 1 800 526-5142.
Removing SIMMs
Because the SIMMs on the RP are not intended to be replaced often, if at all, the SIMM sockets do
not use the thumb tabs that are often used in PCs and other computer equipment. Each RP SIMM
socket has two metal retaining springs, one at each end. (See Figure 5-9.)When a SIMM is fully
seated in the socket, the retaining springs snap upward into the holes at the ends of the SIMM to lock
