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). DRAM SIMMs must be removed or installed in the field by a Cisco-certified maintenance Note provider only. Improper handling of the bus and tag and ESCON channel cables and interface adapters Caution can cause significant problems for other devices on the same channel as the CIP2.
You need the following tools and parts to upgrade a CIP2. If you need additional equipment, contact a customer service representative for ordering information. • Number 2 Phillips or a 3/16-inch flat-blade screwdriver • DRAM upgrade products—MEM-CIP-64M= or MEM-CIP-128M= • ESD-preventive wrist strap or other device for preventing ESD damage 2 Upgrading DRAM on the CIP2...

Upgrading DRAM on the CIP2 This section includes procedures to perform an upgrade of DRAM SIMMS on the CIP2. 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.

Upgrading DRAM on the CIP2 Disconnect the Y cable from each PCA and the ESCON cable from each ECA. (See Step 5 Figure 2.) Do not disconnect the V-type cables from the Y cable. To disconnect the Y cable from the PCA, it might be necessary to temporarily remove any strain relief used to support the V-type bus and tag cables, which are quite heavy.

Upgrading DRAM on the CIP2 Installing a CIP2 Follow these steps to install the CIP2 in the router: Attach an ESD-preventive wrist strap between you and the chassis. Step 1 Hold the CIP2 handle with one hand and placing your other hand under the carrier to Step 2 support the CIP2, guide it into the slot.

Upgrading DRAM on the CIP2 Place the select/bypass switch in select mode. (See Figure 7.) The select/bypass switch Step 8 marked S (for select mode) and B (for bypass mode) is located on the rear of the PCA connector. (See Figure 7.) The select/bypass switch is required to allow the cable to be separated from the PCA without “opening”...
