Power Supply Requirements
The Catalyst 4006 switch requires dual power supplies. The Catalyst 4500 series switch requires one
power supply (dual for redundancy).
Release 7.x Memory Requirements
The Catalyst 4500 series supervisor engine software release 7.x requires a minimum of 64-MB DRAM
installed on your supervisor engine. All Supervisor Engine II modules are shipped with 64-MB DRAM.
If your Supervisor Engine I has less than 64-MB DRAM, you can add more memory by ordering the
32-MB DRAM upgrade (Cisco product number MEM-C4K-32-RAM=) for the Catalyst 4500 series
Supervisor Engine I.
ROMMON Requirements
If the Boot ROM (ROMMON) loaded onto your switch is version 4.5(1) or earlier, you need to upgrade
the ROMMON to at least version 5.4(1) in order to run software release 7.1 or later.
Upgrading the ROMMON
Follow these guidelines to upgrade the ROMMON on your switch:
Caution To avoid actions that might make your system unbootable, read this entire section before starting the
upgrade.
You can perform this procedure entirely over a Telnet connection, but if something fails, you will need
to have access to the console serial port. If done improperly, the system can become unbootable, and you
will have to return it to Cisco for repair.
