This section is divided into the following topics:
•Required Tools, page 8
•Removing the Supervisor Engine 720, page 8
•Removing and Installing the DRAM DIMMs, page 11
•Installing the Supervisor Engine 720, page 14
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 upgrade 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 720
To install the DRAM DIMM upgrade, you must first remove the Supervisor Engine 720 from the switch.
The Supervisor Engine 720 is a required system component. If only one Supervisor Engine 720 is
present, removing it while the system is operating causes the system to halt. When two Supervisor
Engine 720s are installed, hot swapping allows you to remove and replace one of the supervisor engines
without turning off the system power.
To avoid erroneous failure messages, note the current configuration of all interfaces before you remove
or replace another switching module, and allow at least 15 seconds for the system to reinitialize after a
module has been removed or replaced.

Installing the SP and RP Memory Upgrade Kit
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 Disconnect any network interface cables attached to the supervisor engine.
Step 2 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 module 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 module.
Step 3 Loosen the two captive screws on the supervisor engine that is to be removed.
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. 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 5 Place the supervisor engine on an antistatic mat or antistatic foam.

Installing the SP and RP Memory Upgrade Kit
To install the DRAM DIMM upgrade kit, perform these steps:
Step 1 Remove the old DRAM DIMM from its socket by pulling the locking spring clips on both sides
outward and tilting the DIMM free of the clips. Be careful not to break the clips on the DIMM
connector.
Step 2 Holding the DIMM by its edges, gently lift to disconnect it from the DIMM socket, and place the
DIMM on an antistatic mat or foam.
Step 3 Remove the upgrade DIMM from the antistatic package.
Step 4 Hold the DIMM between your thumbs and forefingers, with the connector edge (the metal fingers)
down, and insert the connector edge of the DIMM into the socket connector.
Note A notch (key) is located on the right connector edge of the DIMM. (See Figure 5.) This notch
key ensures that the DIMM is correctly oriented in the socket.
Step 5 Slide the DIMM into the connector so that none of the metal fingers at the edge of the DIMM are
visible under the lining of the connector.
Caution When inserting the DIMM, use firm but not excessive pressure. If you damage a socket, you must
return the supervisor engine to Cisco for repair.
Step 6 Press down on the edges of the DIMM until the DIMM clicks into place. (See Figure 5.)

Installing 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 module.
To reinstall the Supervisor Engine 720 in the chassis, follow these steps:
Step 1 Verify that the captive installation screws are tightened on all modules installed in the chassis. This
action assures that the EMI gaskets on all modules are fully compressed to maximize the space for the
removed module.
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 module.
Step 2 Fully open both ejector levers on the supervisor engine that you are installing. (See Figure 6.)

Step 3 Depending on the orientation of the slots in the chassis (horizontal or vertical), perform one of the
following two sets of stepsfor positioning the module in a chassis with either horizontal or vertical slots:
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 become 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. Verify that the STATUS LED is lit.
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 module has not successfully completed the boot
process and may have encountered an error.

Translated Safety Warnings
This section repeats in multiple languages the basic warnings that appear in this publication.
Statement 1029—Blank Faceplates and Cover Panels
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.
Waarschuwing
Lege vlakplaten en afdekpanelen vervullen drie belangrijke functies: ze voorkomen blootstelling
aan gevaarlijke voltages en stroom binnenin het frame, ze bevatten elektromagnetische storing
(EMI) hetgeen andere apparaten kan verstoren en ze leiden de stroom van koellucht door het frame.
Het systeem niet bedienen tenzij alle kaarten, vlakplaten en afdekkingen aan de voor- en achterkant
zich op hun plaats bevinden.
Varoitus
Tyhjillä tasolaikoilla ja suojapaneeleilla on kolme tärkeää käyttötarkoitusta: Ne suojaavat
asennuspohjan sisäisille vaarallisille jännitteille ja sähkövirralle altistumiselta; ne pitävät
sisällään elektromagneettisen häiriön (EMI), joka voi häiritä muita laitteita; ja ne suuntaavat
tuuletusilman asennuspohjan läpi. Järjestelmää ei saa käyttää, elleivät kaikki tasolaikat, etukannet
ja takakannet ole kunnolla paikoillaan.
Attention
Ne jamais faire fonctionner le système sans que l’intégralité des cartes, des plaques métalliques et
des panneaux avant et arrière ne soient fixés à leur emplacement. Ceux-ci remplissent trois
fonctions essentielles : ils évitent tout risque de contact avec des tensions et des courants
dangereux à l’intérieur du châssis, ils évitent toute diffusion d’interférences électromagnétiques
qui pourraient perturber le fonctionnement des autres équipements, et ils canalisent le flux d’air de
refroidissement dans le châssis.
