HP ESCON PA Microcode Overview
Microcode, also known as firmware, is a set of processor-specific software instructions that enables and
manages the features and functions of a specific port adapter type. At system startup or reload, the
system loads the microcode for each port adapter type present in the system.
The entire HP ESCON PA microcode image is delivered on a router Flash memory card or SanDisk
memory device, or you can download it from Cisco.com.
New microcode is released to enable new features, improve performance, or fix known problems in
earlier versions. The Cisco 7200 series routers support downloadable software and microcode images
for most upgrades. This support lets you download new or upgraded images remotely, store the images
in router memory, and load the new images at system startup without physically accessing the router.
You can store multiple versions of an image in Flash or SanDisk memory for a specific processor type,
and use configuration commands to specify which version of the image loads at startup. All port adapters
of the same type (for example, all HP ESCON PA port adapters) use the same microcode image.
By default, the HP ESCON PA microcode is loaded from the router Flash memory card or SanDisk
memory device for the Cisco 7200 series routers. The default HP ESCON PA microcode version is found
by entering the show microcode command.
