Installing the SP and RP Memory Upgrade Kit
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.
