Upgrade Installation Note
Part Number: MEM-S1-128MB=
The MEM-S1-128MB= memory upgrade kit consists of 2 64-MB dynamic random-access memory
(DRAM) dualinline memory modules (DIMMs). The memory upgrade kit upgrades the total supervisor
engine memory from 64 MB (2 32-MB DIMMs) to 128 MB (2 64-MB DIMMs).
This publication describes how to removeand install the DRAM DIMMson the followingCatalyst 6500
series supervisor engines:
• WS-X6K-S1A-MSFC2
• WS-X6K-SUP1A-PFC
• WS-X6K-SUP1A-2GE
Note The WS-X6K-SUP1A-2GE shipped since June 2004 has 128 MB installed as default. Enter the
show version mod command to display the total DRAM installed on the supervisor engine.
• WS-X6K-SUP1A-MSFC—See the following Note statements for information about the
MEM-S1-128MB-UPG= upgrade kit for the WS-X6K-SUP1A-MSFC.
Note Withthe exceptionof WS-X6K-SUP1A-MSFC, all other Supervisor Engine 1A modules can upgrade to
128-MB DRAM using the MEM-S1-128MB= upgrade kit. To upgrade to 128-MB DRAM on the
WS-X6K-SUP1A-MSFC, use the MEM-S1-128MB-UPG= upgrade kit which also includes an MSFC2
upgrade.

beneath the MSFC. The MSFC is not field replaceable. Re-installing the MSFC could damage your
supervisor engine. To upgrade the DRAM, you must also upgrade the MSFC to an MSFC2. Both
upgrades are available in the MEM-S1-128MB-UPG= upgrade kit.

Memory Recommendations and Requirements
See Table 1 for memory recommendations and requirements.

Catalyst Software

Safety Overview
Table 1 Memory Recommendations and Requirements (continued)
Catalyst Software
Release Memory Recommendation/Requirement
7.x With software releases 7.5(1) and later, 64-MB DRAM may not provide
adequate free memory forallconfigurations.Withlarge,existingconfigurations
using many features, or when enabling new features available in release 7.5 and
later, 64-MB DRAM might not be enough memory. We recommend upgrading to
128-MB DRAM to ensure that adequate free memory is available to the system at
all times.
Software release 7.6(4)and later 7.6(x)releases are toolargeto fit in the64-MB
DRAM that originally shipped on some Supervisor Engine 1A modules. You
must upgrade to 128-MB DRAM.
8.x With Catalyst software releases 8.1(1) and later, your Supervisor Engine 1A
configuration requires 128-MB DRAM.
Caution The supervisor engine is a required system component. If only one supervisor engine is present,
removing it while the system is operating causes the system to halt.

Warning
Blank faceplates and cover panels serve three important functions: they prevent exposure to
hazardous voltages andcurrents insidethe chassis; theycontain electromagneticinterference (EMI)
that might disruptother equipment;and they directthe flowof cooling air through thechassis. Do not
operate thesystem unlessall cards, faceplates, front covers, and rearcovers arein place. Statement

Required Tools
These tools are required to upgrade the supervisor engine DRAM:
• Antistatic mat or foam pad to support the removed supervisor engine
• 3/16-inch flat-blade screwdriver for the captive installation screws on the supervisor engine
• Number 1 Phillips-head screwdriver for the screws and cap nut that fasten the MSFC2 to the
supervisor engine (if an MSFC2 is installed 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
Refer to the Catalyst 6500 Series Switch Installation Guide for the locations of the ESD connectors on
the Catalyst 6500 series switches.
Removing the MSFC2
Note If upgrading a supervisor engine withoutanMSFC2 (WS-X6K-SUP1A-PFC orWS-X6K-SUP1A-2GE),
proceed to the “Upgrading the DRAM DIMM” section on page 7 to install the DRAM.
Note The DRAM DIMMs on the Supervisor Engine1A withan MSFC (WS-X6K-SUP1A-MSFC) are located
beneath the MSFC. The MSFC is not field replaceable. Re-installing the MSFC could damage your
supervisor engine. To upgrade the DRAM, you must also upgrade the MSFC to an MSFC2. Both
upgrades are available in the MEM-S1-128MB-UPG= upgrade kit.
For information on removing the MSFC, refer to the Catalyst 6500 Series Multilayer Switch Feature

Caution Always use an ESD wriststrap when handlingmodules orcoming into contactwith internalcomponents.
Before you remove the supervisor engine, you should first upload the current configuration to a server.
You can recover the configuration by downloading it from the server to the nonvolatile memory of the
supervisor engine.For more information,refer to Chapter26, “Workingwith ConfigurationFiles,”in the
Catalyst 6500 Series Software Configuration Guide.
The DRAM is located beneath the MSFC2. To upgrade the supervisor engine, you must remove the
MSFC2 from the supervisor engine.

Removing the MSFC2
To remove the MSFC2 from the supervisor engine, follow these steps:
Step 1 Upload the current configuration to a server. On any modules running Cisco IOS software, save the
running configuration.
Step 2 Remove the supervisor engine from the Catalyst 6500 series switch. (Refer to the Catalyst 6500 Series
Module Installation Guide for removal instructions.)
Step 3 Place the supervisor engine on an antistatic mat or foam.
Step 4 Remove the securing screws and cap nutthat secure the MSFC2 to the supervisor engine. (See Figure 1
for an MSFC2 shipped before November 2001, or see Figure 2 for an MSFC2 shipped after November
2001.)
Note The MSFC2 shipped after November 2001 is physically smaller than the previous MSFC2 and
is not secured with a cap nut. (See Figure 2.)

Step 5 Hold the top edge of the MSFC2 with your right hand and the bottom-left edge with your left hand.
(See Figure 1 for an MSFC2 shipped before November 2001 or Figure 2 for an MSFC2 shipped after
November 2001.) Gently lift the MSFC2 with both hands simultaneously, and remove the MSFC2 from
the supervisor engine.
Caution Use care not to damage the connectors on the supervisor engine. If you damage a connector, you will
have to return the supervisor engine to Cisco for repair.
Step 6 Place the MSFC2 on an antistatic mat or antistatic foam pad.
Proceed to the “Upgrading the DRAM DIMM” section on page 7 to install the DRAM.
