Upgrading DRAM on the CIP2
Product Numbers: MEM-CIP-64M= and MEM-CIP-128M=
This publication contains procedures for upgrading dynamic random-access memory (DRAM)
single in-line memory modules (SIMMs) on the second-generation Channel Interface Processor
(CIP2).
Note
DRAM SIMMs must be removed or installed in the field by a Cisco-certified maintenance
provider only.
Caution
Improper handling of the bus and tag and ESCON channel cables and interface adapters
can cause significant problems for other devices on the same channel as the CIP2. Mainframe
processors can, in some circumstances, be rendered inoperable due to system crashes caused by
improper cable handling. We strongly recommend that only Cisco-certified maintenance providers
connect and disconnect channel cables between the router and the mainframe, and perform
maintenance procedures on the CIP2.
Note
For more complete information on the CIP2, refer to the configuration note
Second-Generation Channel Interface Processor (CIP2) Installation and Configuration, which ships
with the CIP2 and is available on the Cisco Connection Documentation, Enterprise Series CD-ROM,
on the Cisco Products disc.
