PDC Distribution
HP Electronic Support Center (HPESC) Access
This method of PDC distribution is treated as if it were a software patch. The process of retrieving and/or
downloading a software patch is the same process that is used to get the PDC update files.
The patches are available on HP Electronic Support Center (HPESC) for immediate Internet access. The
patches can be downloaded electronically from HPESC via email, the World Wide Web (WWW), or ftp.
The following items are discussed in this section:
• File Naming Convention
• Downloading patches via World Wide Web (WWW)
• Downloading patches via ftp
File Naming Convention
The patch file, which is a shar file, uses the following naming convention for firmware update patch files:
PF_TPPPdddd
where:
PF - signifies firmware patches (Patch Firmware)
T - Firmware Category
C = CPU
I = I/O card
N = Network card
D = Disk
T = Tape
PPP - Product Description
dddd - Datecode or Revision
The following is an example of a “shar” patch file name for a PDC update:
PF_CKHK0013
|\\ /\\ /
| | ^------ 0013 = Firmware revision 1.3
| |--------- KHK = Kittyhawk
|----------- C = CPU firmware update
The shar patch file contains other files that are named as follows:
TPPPdddd.zzzz
where:
zzz - File Extension
text = readme file
frm = firmware update image
As an example, the PF_CKHK0013 shar file would contain:
CKHK0013.text - readme file
and
CKHK0013.frm - PDC firmware update image
