Safety Overview
Safety warnings appear throughout this publication in procedures that, if performed incorrectly, may harm you. A warning symbol precedes each warning statement.
Warning
This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. To see translations of the warnings that appear in this publication, refer to the "Translated Safety Warnings" section in this document.
Warning
Before you install, operate, or service the system, read the Site Preparation and Safety Guide. This guide contains important safety information you should know before working with the system.
Warning
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Required Tools
These tools are required to upgrade the memory on the OSM:
•
3/16-inch flat-blade screwdriver for the captive installation screws on the OSM
•
Antistatic mat or antistatic foam
•
Your own ESD-prevention equipment or the disposable grounding wrist strap included with all upgrade kits, field-replaceable units (FRUs), and spares
CautionAlways use an ESD wrist strap when handling modules or coming into contact with internal components.
Upgrading the OSM Memory
This section provides the procedures for removing and replacing the memory on the OSM.
The synchronous dynamic random-access memory (SDRAM) on the OSM is contained in one small outline dual inline memory module (SODIMM) (see Figure 1).
The OSM has a default memory configuration of 64 MB with Error Checking and Correction (ECC) (single-bit error detection and correction; 2-bit error detection) and is upgradable to 128 MB, 256 MB, or 512 MB.
Note
You should use only 100-MHz SDRAM SODIMMs. A Cisco part number appears on the SODIMMs.
CautionTo prevent ESD damage, handle the SODIMM by the card edges only (see Figure 3). Place the removed SODIMM on an antistatic mat or store it in an antistatic container.
Removing the SODIMM
Warning
During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself.
To remove the existing SODIMM, follow these steps:
Step 1
Make sure you take the necessary precautions to prevent ESD damage.
Step 2
Remove the OSM from the system (refer to the Optical Services Module Installation and Configuration Note for removal instructions).
Step 3
Place the OSM on an antistatic mat or pad.
Step 4
Locate the SODIMM (see Figure 1).
Figure 1 Location of SDRAM SODIMM on an OSM
Step 5
Release the spring clips from the SODIMM that you want to remove, and release the SODIMM from the socket (see Figure 2).
Figure 2 Releasing the SODIMM Spring Clips
Step 6
When both ends of the SODIMM are released from the socket, grasp the ends of the SODIMM with your thumb and forefinger and pull the SODIMM completely out of the socket. Handle the edges of the SODIMM only; avoid touching the memory modules, pins, or traces (the metal fingers along the connector edge of the SODIMM), along the connector edge.
Step 7
Place the SODIMM in an antistatic container to protect it from ESD damage.
This completes the SODIMM removal procedure. Proceed to the next section to install the new SODIMM.
Installing the New SODIMM
CautionSODIMMs are sensitive components that are susceptible to ESD damage. Handle SODIMMs by the edges only; avoid touching the memory modules, pins, or traces (the metal fingers along the connector edge of the SODIMM). (See Figure 3.)
Figure 3 Handling a SODIMM
Follow these steps to install the new SODIMM:
Step 1
Remove a new SODIMM from the antistatic container.
Step 2
Hold the SODIMM component side up, with the connector edge (the metal fingers) away from you.
Step 3
Hold the sides of the SODIMM between your thumb and middle finger, with your forefinger against the far edge, opposite the connector edge (see Figure 3).
Step 4
Tilt the SODIMM to approximately the same angle as the socket, and insert the connector edge into the socket.
CautionWhen inserting SODIMMs, use firm but not excessive pressure. If you damage a socket, you will have to return the OSM to the factory for repair.
Step 5
Press the SODIMM down until it is secured by the spring clips.
Step 6
When the SODIMM is installed, check the two alignment holes and ensure that the spring retainer is visible. If it is not, the SODIMM is not seated properly. If any SODIMM appears misaligned, carefully remove it and reseat it in the socket. Push the SODIMM firmly back into the socket until the retainer springs snap into place.
Step 7
Reinstall the OSM in the system (refer to the Optical Services Module Installation and Configuration Note for installation instructions).
