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) dual inline 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 remove and install the DRAM DIMMs on the following Catalyst 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 With the exception of 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.

Safety Overview
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.
Safety Overview
Safety warnings appear throughout this publication in procedures that may harm you if performed
incorrectly. A warning symbol precedes each warning statement.
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Statement 1030
Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution
when servicing. Statement 1034
7.x With software releases 7.5(1) and later, 64-MB DRAM may not provide
adequate free memory for all configurations. With large, existing configurations
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 too large to fit in the 64-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.

Required Tools
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
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 without an MSFC2 (WS-X6K-SUP1A-PFC or WS-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 Engine 1A with an 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 wrist strap when handling modules or coming into contact with internal components.
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 Chapter 26, “Working with Configuration Files,” 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.

Upgrading the DRAM DIMM
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.
This section describes how to remove the existing DIMMs and replace them with the upgrade DIMMs.
The DRAM DIMM location is shown in Figure 3.
Note The Supervisor Engine 1A DRAM uses two DIMMs, one stacked on top of the other.
Figure 3 DRAM Location
Caution Always use an ESD wrist strap when handling modules or coming into contact with internal components.
To install the DRAM upgrade, follow these steps:
Step 1 Remove the DRAM DIMMs from the socket by pulling the locking spring clips on both sides of the
DIMM holder outward, and tilt the DIMM free of the clips. (See Figure 4.) Be careful not to break the
clips on the DIMM connector.
Note The Supervisor Engine 1A DRAM uses two DIMMs, one stacked on top of the other. Remove the upper
DIMM first, and then remove the lower DIMM.

Step 2 Hold the DIMM by its edges, gently lift and remove it, and place it on an antistatic mat or foam.
(See Figure 5.)
Figure 5 Handling a DIMM
Caution DIMMs are sensitive components that are susceptible to ESD damage. To prevent ESD damage, handle
DIMMs by the edges only; avoid touching the memory modules, pins, or traces (the metal fingers along
the connector edge of the DIMM). (See Figure 5.)
Step 3 Remove one upgrade DIMM from the antistatic container.
Step 4 Hold the DIMM by its edges. (See Figure 5.)
Step 5 Tilt the DIMM to approximately the same angle as the socket, and insert the connector edge into the
socket. Note the notch (key) on the right connector edge of the DIMM. (See Figure 5.) This key assures
correct orientation of the DIMM in the socket.
Note The Supervisor Engine 1A DRAM uses two DIMMs, one stacked on top of the other. Install the lower
DIMM first.
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.

Installing the MSFC2
Step 6 Press the DIMM down until it is secured by the spring clips. (See Figure 6.)
Figure 6 Installing the DIMM
Step 7 When the DIMM is installed, check the two alignment holes and ensure that the spring retainer is visible.
If it is not, the DIMM is not seated properly. If the DIMM appears misaligned, carefully remove it and
reseat it in the socket. Push the DIMM firmly back into the socket until the retainer springs snap into
place.
Step 8 Repeat Step 3 through Step 7 for the second (upper) DIMM.
Installing the MSFC2
Note The MSFC2 that shipped after November 2001 is physically smaller than the previous MSFC2.
To install the MSFC2 on the supervisor engine, follow these steps:
Step 1 Align the MSFC2 with the standoffs on the supervisor engine. The MSFC2 shipped before
November 2001 will also align with the male standoff. (See Figure 7.) Make sure that the remaining
mounting holes on the MSFC2 are aligned with the remaining standoffs.
