Required Tools

The following tools are required to remove and replace the DIMM:

Antistatic mat or foam pad to support the removed supervisor engine

Flat-blade screwdriver to remove and tighten the captive installation screws that secure the supervisor engine in its slot

A wrist strap or other grounding device to prevent electrostatic discharge (ESD) damage


Note   Refer to the installation guide for your switch for ESD details including the locations of the ESD connectors on the Catalyst 4000 family switches.


Safety Recommendations

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.


Ensuring Safety

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.

Keep the chassis area clear and free of dust during and after installation.

Keep tools and chassis components off the floor and away from foot traffic.

Avoid wearing jewelry (including rings and chains) or other items that could get caught in the chassis. Avoid wearing any loose clothing or securely fasten items such as ties, scarves, or sleeves.


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.


Working Safely with Electricity

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:

Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working.

Do not work alone when potentially hazardous conditions exist.

Never assume that power has been disconnected from a circuit; always check.

Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

Removing the Supervisor Engine

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.

Figure 1 Ejector Levers and Captive Installation Screws

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.


Note   When removing the supervisor engine, use the ejector levers to ensure that the connector pins disconnect from the backplane properly. Any supervisor engine or switching module that is only partially connected to the backplane can disrupt the system. Follow the installation instructions carefully. Detailed instructions for removing and installing switching modules are described in the installation guide for your switch.


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.

Installing the DIMM

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.

Figure 2 Supervisor Engine DIMM Slot Location


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).

Figure 3 Installing the 32-MB DIMM Card

Installing the Supervisor Engine

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).

Figure 4 Installing the Supervisor Engine

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.

Figure 5 Module Ejector Lever Operation

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.

FCC Class A Compliance

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:

Turn the television or radio antenna until the interference stops.

Move the equipment to one side or the other of the television or radio.

Move the equipment farther away from the television or radio.

Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

Modifications to this product not authorized by Cisco Systems could void the FCC approval and negate your authority to operate this product.
