Note The HP ESCON PA supports online insertion and removal (OIR), which allows you to install or remove
an HP ESCON PA while the system is operating without shutting down system power.
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.
• When ordered as a spare, the HP ESCON PA microcode is available via Cisco.com.
• When ordered as part of a new system, the HP ESCON PA microcode is available on Flash memory
cards and SanDisk memory devices (which also include the Cisco IOS release compatible with the
microcode version) and via Cisco.com.
• When shipped with a new system, there is a default setting in Cisco IOS that points to the HP
ESCON PA microcode with which it has been virtually bundled (separately bundled and preloaded
onto the Flash memory card or SanDisk memory device along with the compatible Cisco IOS
software). The Cisco IOS software loads the HP ESCON PA microcode image onto the port adapter
when the router boots and when an HP ESCON PA is inserted into a router that has already been
booted.
We recommend that you use the version of the HP ESCON PA microcode that is virtually bundled with
your Cisco IOS software. If you choose not to, you must copy a microcode image onto the router Flash
memory card or SanDisk memory device and use the microcode router configuration command to
instruct the Cisco IOS software to use the microcode image you copied instead of the microcode image
virtually bundled with your version of the Cisco IOS software.
• For instructions on placing HP ESCON PA microcode on the router Flash memory card, see the
“Copying a New Image to the Flash Memory Card on a Cisco 7200 Series Router” section on
page 36.
• For instructions on placing HP ESCON PA microcode on the SanDisk memory device, see the
“Using SanDisk Devices” section on page 38.
• For instructions on configuring Cisco IOS to use an HP ESCON PA image from the router Flash
memory card or SanDisk memory device, refer to the “Configuring the HP ESCON PA Microcode”
section on page 34.
