Chapter 4 Removing and Replacing FRUs
Supervisor Memory Upgrade
Supervisor Memory Upgrade This section describes how to perform a memory upgrade. You might need to upgrade mem ory on the
Supervisor Engine 6-E for the following reasons:
• To upgrade to a new Cisco IOS feature set or release that requires additional memory. (Memory
requirements for each feature set and release are available in the release notes for that release.)
• To use very memory-intensive features.
This document describes how to upgrade dynamic memory. The Supervisor Engine 6-E ships with 512
MB and can be upgraded to 1 GB in the form of an SDRA M miniDIMM.
Tools and Equipment Needed
You need the following tools and equipment to remove and install miniDIMMs in a Supervisor
Engine 6-E:
• Number 2 Phillips screwdriver
• Small flat-blade screwdriver
• ESD-preventive wrist strap
• Antistatic mat
Removing Memory
You will not need to remove the base memory to perform a memory upgrade, but it may make installing
the new memory easier. This procedure presumes you have already removed the supervisor e ngine from
the switch. To remove an SDRAM miniDIMM:
Step 1 Attach an ESD-preventive wrist strap and ensure that it makes good contact with your skin. Connect the
equipment end of the wrist strap to the metal back plate of the chassis, avoiding contact with the
connectors.
Step 2 On the mainboard, locate the SDRAM miniDIMM sockets. (See Figure 4-25.)
