This configuration note contains procedures for installing the 32-MB dual inline memory module (DIMM) upgrade kit for the Catalyst 4000 family supervisor engine.
This document contains the following sections:
The following tools are required to remove and replace the DIMM:
Safety warnings appear throughout this note 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, you must be aware of the hazards involved with electrical circuitry and familiar with standard practices for preventing accidents. To see translated versions of the warnings that appear in this publication, refer to the Appendix, "Translated Safety Warnings" in the installation guide for your switch. |
Follow these guidelines to ensure your safety and protect the equipment. This list does not include all potentially hazardous situations that you may be exposed to as you install the switch, so be alert.
| Warning
Only trained and qualified personnel should be allowed to install or replace this equipment. |
| Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. |
The supervisor engine, power supplies, fan assembly, and switching modules are designed to be removed and replaced while the system is operating without presenting an electrical hazard or damage to the system.
Follow these basic guidelines when working with any electrical equipment:
To install the DIMM, you must first remove the supervisor engine from the switch.
 | Caution Always use an ESD wrist strap when handling modules or coming into contact with internal components. |
| Caution The supervisor engine is a required system component. Removing a supervisor engine while the system is operating causes the system to halt. |
Before you remove a supervisor engine, you should first upload the current configuration to a server. This saves time when bringing the module back online. You can recover the configuration by downloading it from the server to the nonvolatile memory of the supervisor engine.
To remove a supervisor engine, perform these steps:
| 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. |
Step 1 Use a screwdriver to loosen the captive installation screws at the left and right sides of the module.
Step 2 Grasp the left and right ejector levers; simultaneously pull the left lever to the left and the right lever to the right to release the module from the backplane connector.
Step 3 As you pull the module out of the slot, place one of your hands under the carrier to support it. Avoid touching the module itself.
Step 4 Carefully pull the module straight out of the slot, keeping one hand under the carrier to guide it. Keep the module at a 90-degree orientation to the backplane (horizontal to
the floor).
Step 5 Place the removed module on an antistatic mat or antistatic foam.
The DIMM slot is located on the motherboard of the supervisor engine (see Figure 2). Once you remove the supervisor engine from the Catalyst 4000 family switch, you can install the DIMM.
| Caution Always use an ESD wrist strap when handling modules or coming into contact with internal components. |
 | Caution Handle the DIMM by its edges only; avoid touching the memory module, pins, or traces (the metal fingers along the connector edge of the DIMM). DIMMs are sensitive components that are susceptible to ESD damage and can be damaged by mishandling. |
Remove the 32-MB DIMM from its package, holding it by its edges, and carefully insert it into the connector so that it clicks into place (see Figure 3).
When installing the supervisor engine, you must install it in slot 1 of your Catalyst 4000 family switch.
| Caution To prevent ESD damage, handle switching modules by the carrier edges only. |
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 install the supervisor engine, follow these steps:
Step 1 Take the necessary precautions to prevent ESD damage.
Step 2 Hold the front panel of the supervisor engine with one hand, and place your other hand under the carrier to support the module. Do not touch the printed circuit boards or connector pins (see Figure 4).
Step 3 Align the edges of the supervisor engine carrier with the slot guides on the sides of the switch chassis.
Step 4 Pivot the two module ejector levers out away from the faceplate. The ejector levers are shown pivoted out in Figure 5.
Step 5 Keeping one hand under the carrier to guide the supervisor engine, carefully slide it into the slot on the Catalyst 4000 family switch until the ejector levers click into place on the chassis. Be sure to keep the module horizontal to the backplane and avoid touching any of the components on the module.
Step 6 Using the thumb and forefinger of each hand, simultaneously pivot in both ejector levers, as shown in Figure 5, to fully seat the supervisor engine in the backplane connector.
Step 7 Tighten the captive installation screws with a screwdriver.
Catalyst 4000 family modules, when intalled in a system, comply with the standards listed in Table 1:

This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
Modifications to this product not authorized by Cisco Systems could void the FCC approval and negate your authority to operate this product.
