Cisco Catalyst 6500 128MB DRAM Upgrade on Supervisor (SUP1), Spare MEM-S1-128MB=-3RD Benutzerhandbuch

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 warnings appear throughout this publication in procedures that may harm you if performed 
incorrectly. A warning symbol precedes each warning statement.

Only trained and qualified personnel should be allowed to install, replace, or service this equipment. 
Statement 1030

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.

This warning symbol means danger. You are in a situation that could cause bodily injury. Before you 
work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar 
with standard practices for preventing accidents. Use the statement number provided at the end of 
each warning to locate its translation in the translated safety warnings that accompanied this 
device. Statement 1071
