Safety Overview
Safety warnings appear throughout this publication in procedures that may harm you if performed incorrectly. A warning symbol precedes each warning statement.
Statement 1071—Warning Definition
Installing the DRAM Memory Kit
This section is divided into the following topics:
•Removing the Supervisor Engine 32 from the Chassis
•Removing and Installing the DRAM DIMMs
•Installing the Supervisor Engine 32
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
Required Tools
The following tools are required to perform the memory kit installation:
•Antistatic mat or foam pad to support and protect the removed supervisor engine
•3/16-inch flat-blade screwdriver for the captive installation screws on the supervisor engine
•Your own ESD-prevention equipment or the disposable grounding wrist strap included with all upgrade kits, field-replaceable units (FRUs), and spares
Caution Always use an ESD wrist strap when handling modules or coming into contact with internal components.
Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029
Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034
Removing the Supervisor Engine 32 from the Chassis
To install the DRAM memory kit, you must first remove the Supervisor Engine 32 from the chassis.
The Supervisor Engine 32 is a required system component. If only one Supervisor Engine 32 is present, removing it while the system is operating causes the system to halt. When two Supervisor Engine 32s are installed, hot swapping allows you to remove and replace one of the supervisor engines without turning off the system power.
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. Statement 94
To remove the Supervisor Engine 32, follow these steps:
Step 1 Attach an ESD grounding strap to your wrist and to ground. (If you are unsure about the correct way to attach an ESD grounding strap, refer to the "Attaching Your ESD Grounding Strap" section for instructions.)
Step 2 If there is only one SDisconnect any interface cables attached to the supervisor engine.
Step 3 Verify that the captive installation screws on all of the modules in the chassis are tight. This step ensures that the space created by the removed supervisor engine is maintained.
Note If the captive installation screws are loose, the EMI gaskets on the installed modules will push the modules toward the open slot, reducing the opening size and making it difficult to reinstall the supervisor engine.
Step 4 Loosen the two captive screws on the supervisor engine that is to be removed.
Step 5 Depending on the orientation of the slots in the chassis (horizontal or vertical), perform one of the following two sets of steps:
Horizontal slots
a. Place your thumbs on the left and right ejector levers, and simultaneously rotate the levers outward to unseat the supervisor engine from the backplane connector. (See Figure 1.)
b. Grasp the front edge of the supervisor engine, and slide the supervisor engine partially out of the slot. Place your other hand under the supervisor engine to support the weight of the module. Do not touch the module circuitry. (See Figure 2.)
Vertical slots
a. Place your thumbs on the ejector levers located at the top and bottom of the supervisor engine, and simultaneously rotate the levers outward to unseat the supervisor engine from the backplane connector.
b. Grasp the edges of the supervisor engine, and slide the supervisor engine straight out of the slot. Do not touch the module circuitry.
Step 6 Immediately place the supervisor engine on an antistatic mat or antistatic foam.

Removing and Installing the DRAM DIMMs
This section covers the removal of the DRAM DIMM and the installation of the new DRAM DIMM.
To install the DRAM DIMM kit, perform these steps:
Step 1 Attach an ESD grounding strap to your wrist and to ground. (If you are unsure about the correct way to attach an ESD grounding strap, refer to the "Attaching Your ESD Grounding Strap" section for instructions.)
Step 2 Locate the DRAM DIMM on the supervisor engine. (See Figure 3.)
Figure 3 DRAM DIMM Location on the Supervisor Engine 32
Step 3 Release the old DRAM DIMM from its socket by simultaneously pulling the two locking spring tabs on the socket sides outward and pivoting the DRAM DIMM free of the tabs. Be careful not to bend the locking spring tabs too far, you can break the tabs on the DIMM socket. (See Figure 4.)
Figure 4 Releasing the Spring Clips
Step 4 Holding the DIMM by its edges, (see Figure 5), gently rock and lift it to disconnect it from the DIMM socket. Immediately place the DRAM DIMM on an antistatic mat or in an antistatic bag.
Figure 5 Handling a DIMM
Step 5 Remove the replacement DRAM DIMM from the antistatic package.
Step 6 Holding the DIMM between your thumbs and forefingers, with the connector edge (the metal fingers) down, carefully slide the DIMM into the socket. Make sure that you fully insert the connector edge of the DIMM into the socket connector.
Note A notch (key) is located on the left connector edge of the DIMM. This notch key ensures that the DIMM is correctly oriented in the socket.
Caution When inserting the DIMM, use firm but not excessive pressure. If you damage a socket, you will have to return the supervisor engine to Cisco for repair.
Step 7 Press down on the edges of the DIMM until the DIMM clicks into place (see Figure 6).

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. Statement 94
To reinstall the Supervisor Engine 32 in the chassis, follow these steps:
Step 1 Attach an ESD grounding strap to your wrist and to ground. (If you are unsure about the correct way to attach an ESD grounding strap, refer to the "Attaching Your ESD Grounding Strap" section for instructions.)
Step 2 Verify that the captive installation screws are tightened on all supervisor engines installed in the chassis. This action assures that the EMI gaskets on all supervisor engines are fully compressed in order to maximize the opening space for the removed supervisor engine.
Note If the captive installation screws are loose, the EMI gaskets on the installed modules will push adjacent modules toward the open slot, reducing the opening size and making it difficult to install the removed supervisor engine.
Step 3 Fully open both ejector levers on the supervisor engine being installed.
Step 4 Depending on the orientation of the slots in the chassis (horizontal or vertical), perform one of the following two sets of steps:
Horizontal slots
a. Position the supervisor engine in the slot. (See Figure 7.) Make sure that you align the sides of the module carrier with the slot guides on each side of the slot.
b. Carefully slide the supervisor engine into the slot until the EMI gasket along the top edge of the module makes contact with the module in the slot above it and both ejector levers have closed to approximately 45 degrees with respect to the module faceplate. (See Figure 8.)
c. Using the thumb and forefinger of each hand, grasp the two ejector levers and press down to create a small 0.040 inch (1 mm) gap between the supervisor engine's EMI gasket and the module above it. (See Figure 8.)
Note Do not press down too forcefully on the levers because they will bend and be damaged.
d. While pressing down, simultaneously close the left and right ejector levers to fully seat the supervisor engine in the backplane connector. The ejector levers are fully closed when they are flush with the module faceplate. (See Figure 8.)
Note Failure to fully seat the module in the backplane connector can result in error messages.
e. Tighten the two captive installation screws on the supervisor engine.
Note Make sure that the ejector levers are fully closed before tightening the captive installation screws.
f. If the chassis is powered down, power-up the chassis.
Verify that the STATUS LED is lit. Periodically check the STATUS LED. If the STATUS LED changes from orange to green, the supervisor engine has successfully completed the boot process and is now online. If the STATUS LED remains orange or turns red, the supervisor engine has not successfully completed the boot process and may have encountered an error.

c. Using the thumb and forefinger of each hand, grasp the two ejector levers and exert a slight pressure to the left, deflecting it approximately 0.040 inches (1 mm) creating a small gap between the supervisor engine's EMI gasket and the module adjacent to it. (See Figure 10.)
Note Do not exert too much pressure on the ejector levers because they will bend and be damaged.
d. While pressing down on the ejector levers, simultaneously close the levers to fully seat the supervisor engine in the backplane connector. The ejector levers are fully closed when they are flush with the supervisor engine faceplate.
e. Tighten the two captive installation screws on the supervisor engine.
Note Make sure that the ejector levers are fully closed before tightening the captive installation screws.
f. If the chassis is powered down, power-up the chassis.
g. Verify that the STATUS LED is lit. Periodically check the STATUS LED. If the STATUS LED changes from orange to green, the supervisor engine has successfully completed the boot process and is now online. If the STATUS LED remains orange or turns red, the supervisor engine has not successfully completed the boot process and may have encountered an error.
Attaching Your ESD Grounding Strap
Electrostatic discharge (ESD) damage, which can occur when modules or other FRUs are improperly handled, results in intermittent or complete failures. Modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, always use an ESD grounding strap when handling modules.
Follow these guidelines for preventing ESD damage:
•Always use an ESD wrist strap and ensure that it makes maximum contact with bare skin. ESD grounding straps are available with banana plugs, metal spring clips, or alligator clips. All Catalyst 6500 series chassis and Cisco 7600 series routers are equipped with a banana plug connector (identified by the ground symbol next to the connector) somewhere on the front panel. If you have an older chassis equipped with a plastic banana plug connector, we recommend that you use either the supplied ESD grounding wrist strap (with a metal clip) or an ESD grounding wrist strap equipped with an alligator clip. If you have a newer chassis that has a bare metal hole as the banana plug connector (also identified by the ground symbol next to the connector), we recommend that you use a personal ESD grounding strap equipped with a banana plug.
•If you choose to use the disposable ESD wrist strap supplied with most FRUs or an ESD wrist strap equipped with an alligator clip, you must attach the system ground lug to the chassis in order to provide a proper grounding point for the ESD wrist strap.
Note This system ground is also referred to as the network equipment building system (NEBS) ground.
•If your chassis does not have the system ground attached, you must install the system ground lug. Refer to the your chassis installation documentation for the procedure.
Note You do not need to attach a supplemental system ground wire to the system ground lug; the lug provides a direct path to the bare metal of the chassis
After you install the system ground lug, follow these steps to correctly attach the ESD wrist strap:
Step 1 Attach the ESD wrist strap to bare skin as follows:
a. If you are using the ESD wrist strap supplied with the FRUs, open the wrist strap package and unwrap the ESD wrist strap. Place the black conductive loop over your wrist and tighten the strap so that it makes good contact with your bare skin.
b. If you are using an ESD wrist strap equipped with an alligator clip, open the package and remove the ESD wrist strap. Locate the end of the wrist strap that attaches to your body and secure it to your bare skin.
Step 2 Grasp the spring or alligator clip on the ESD wrist strap and momentarily touch the clip to a bare metal spot (unpainted surface) on the rack. We recommend that you touch the clip to an unpainted rack rail so that any built-up static charge is then safely dissipated to the entire rack.
Step 3 Attach either the spring clip or the alligator clip to the ground lug screw as follows (See Figure 11):
a. If you are using the ESD wrist strap that is supplied with the FRUs, squeeze the spring clip jaws open, position the spring clip to one side of the system ground lug screw head, and slide the spring clip over the lug screw head so that the spring clip jaws close behind the lug screw head.
Note The spring clip jaws do not open wide enough to fit directly over the head of the lug screw or the lug barrel.
b. If you are using an ESD wrist strap that is equipped with an alligator clip, attach the alligator clip directly over the head of the system ground lug screw or to the system ground lug barrel.
Figure 11 Attaching the ESD Wrist Strap Clip to the System Ground Lug Screw
In addition, follow these guidelines when handling modules:
•Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.
•Place a removed component board-side-up on an antistatic surface or in a static shielding container. If you plan to return the component to the factory, immediately place it in a static shielding container.
•Never attempt to remove the printed circuit board from the metal carrier.
Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm (Mohm).
