Installing the SP Bootflash Memory Kit

The SP memory procedure is divided into the following tasks:

•Removing the Supervisor Engine 720

•Installing the SP Bootflash DIMM

•Reinstalling the Supervisor Engine 720

Removing the Supervisor Engine 720

---

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030

---

The following tools are required to perform the bootflash upgrade kit installation:

•3/16-inch flat-blade screwdriver for the captive installation screws on the supervisor engine

•Antistatic mat or foam pad to support and protect the removed supervisor engine

•Your own ESD-prevention equipment or the disposable grounding wrist strap included with all upgrade kits, field-replaceable units (FRUs), and spares

---

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

---

---

Caution Always use an ESD wrist strap when handling the Supervisor Engine 720 or coming in contact with internal components.

---

To remove the supervisor engine, follow these steps:

---

Step 1 Power down your system.

Step 2 Disconnect any network interface cables attached to the supervisor engine.

Step 3 Attach an ESD grounding strap to your wrist and to ground.

---

Note If you are unsure about the correct way to attach an ESD grounding strap, see the "Attaching Your ESD Grounding Strap" section for instructions.

---

Step 4 Verify that the captive installation screws on all of the modules in the chassis are tight.

---

Note This step ensures that the space created by the removed supervisor engine is maintained. 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 module.

---

Step 5 Loosen the two captive screws on the supervisor engine that is to be removed.

Step 6 Depending on the orientation of the slots in the chassis (horizontal or vertical), perform one of the following 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 7 Immediately place the supervisor engine on an antistatic mat or antistatic foam.

Installing the SP Bootflash DIMM

To install the SP bootflash DIMM, follow these steps:

---

Step 1 Locate the SP bootflash DIMM socket on the Supervisor Engine 720. (See Figure 3.)

The SP bootflash DIMM is on the left side of the Supervisor Engine 720 as you face the front of the board. The RP bootflash DIMM is on the right side of the Supervisor Engine 720 as you face the front of the board.

---

Caution The DIMM is a sensitive component that is susceptible to ESD damage. To prevent ESD damage, wear an ESD grounding wrist strap and handle the DIMM by the edges only; avoid touching the memory modules, pins, or traces (including the metal fingers along the connector edge of the DIMM). 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, see the "Attaching Your ESD Grounding Strap" section for instructions.)

---

Figure 3 SP and RP Bootflash DIMM Locations on the Supervisor Engine 720

Step 2 Release the CompactFlash adapter from the socket by simultaneously releasing the two locking spring clip tabs on either side of the DIMM socket. (See Figure 4, left view.) The CompactFlash adapter will flip up in the socket. (See Figure 4, right view.)

Step 3 Hold the CompactFlash adapter by its edges and carefully remove it from the DIMM socket.

Figure 4 Removing the SP CompactFlash Adapter

Step 4 Immediately place the CompactFlash adapter in an antistatic bag.

Step 5 Open the antistatic bag containing the replacement 64-MB bootflash DIMM.

Step 6 Carefully align the 64-MB bootflash DIMM edge connector with the DIMM socket. Slide the bootflash DIMM edge connector at an angle into the socket. (See Figure 5.)

---

Note Make sure that the DIMM edge connector is fully inserted into the DIMM socket.

You are now ready to reinstall the Supervisor Engine 720 into the switch chassis.

---

Reinstalling the Supervisor Engine 720

---

Caution During this procedure, wear grounding wrist straps and handle modules by the carrier edges only to avoid ESD damage to the card.

---

To reinstall the Supervisor Engine 720 in the chassis, follow these steps:

---

Step 1 Attach an ESD grounding strap to your wrist and to ground.

---

Note If you are unsure about the correct way to attach an ESD grounding strap, see the "Attaching Your ESD Grounding Strap" section for instructions.

---

Step 2 Verify that the captive installation screws are tightened on all modules installed in the chassis.

---

Note This action assures that the EMI gaskets on all modules are fully compressed in order to maximize the opening space for the removed supervisor engine. 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 that is being installed. (See Figure 6.)

Figure 6 Positioning the Supervisor Engine in a Horizontal Slot Chassis

Step 4 Depending on the orientation of the slots in the chassis (horizontal or vertical), perform one of the following sets of steps:

Horizontal slots

a. Position the supervisor engine in the slot. (See Figure 6.) 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 7.)

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 7.)

---

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 7.)

---

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. Power up your system.

g. At the rmon> prompt, enter the boot bootflash:s72033-ipservicesk9-mz.122-18.SXF6.bin command to boot your system with the default Cisco IOS image that is on the SP bootflash. Once your system is running Cisco IOS software, you can download your specific Cisco IOS image from CCO onto the SP bootflash.

h. Verify that the Supervisor Engine 720 STATUS LED is lit.

i. Periodically check the STATUS LED:

•If the STATUS LED changes from orange to green, the module 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.

---

Note After a successful boot process, the router (or the host name) prompt should be seen.

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.

To prevent ESD damage, follow these guidelines:

•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 are equipped with a banana plug connector (identified by the ground symbol next to the connector) on the front panel. If you have an older Catalyst 6500 series 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 Catalyst 6500 series 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 online Catalyst 6500 Series Switches Installation Guide or the Cisco 7600 Series Router Installation Guide 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, you can perform the procedure in this section.

To attach the ESD wrist strap, follow these steps:

---

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 10):

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 10 Attaching the ESD Wrist Strap Clip to the System Ground Lug Screw

---

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohm (Mohm).

---

---

Module Handling Guidelines

When handling modules, follow these guidelines:

•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.
